There are several subspecies and races of Gypsy Moth. There are: - The Asian gypsy moth Lymantria dispar dispar race asian - The European gypsy moth Lymantria dispar dispar race Europe - and Lymantria dispar japonica the Japanese gypsy moth. The image shown here are of Lymantria dispar dispar the European gypsy moth. See reference for Schintlmeister 2004 Male Gypsy moths are brown with a darker brown pattern on their wings. Females are slightly larger and nearly white, with a few dark markings on their wings. Newly hatched caterpillars are black and hairy, later developing a mottled yellow to gray pattern with tufts of bristle like hairs and two rows of blue then red spots on their back. Adult females from Asian strains (west of the Ural mtns.) of Gypsy moth are capable of flight but European strains are incapable of flight. North American populations originated from Europe. Larvae of Asian strains also tend to grow larger. Because of these differences, eradication is usually directed to be more ...

Background: Helicobacter pylori is the first bacterium formally recognized as a carcinogen and is one of the most successful human pathogens, as over half of the worlds population is colonized by the bacterium. H. pylori-induced gastroduodenal disease depends on the inflammatory response of the host and on the production of specific bacterial virulence factors. The study of Helicobacter pylori pathogenic action would greatly benefit by easy-to-use models of infection. Results: In the present study, we examined the effectiveness of the larvae of the wax moth Galleria mellonella as a new model for H. pylori infection. G. mellonella larvae were inoculated with bacterial suspensions or broth culture filtrates from either different wild-type H. pylori strains or their mutants defective in specific virulence determinants, such as VacA, CagA, CagE, the whole pathogenicity island (PAI) cag, urease, and gamma-glutamyl transpeptidase (GGT). We also tested purified VacA cytotoxin. Survival curves were ...

Refill kit for use with NoPests® Codling Moth Pheromone Trap. Contains: 2 monitoring lures and 2 sticky glue boards.. Hang the triangular (delta) cross-section trap during September before the moths start flying using the first lure and sticky glue insert. The trap is designed to protect 3-5 trees in a 12 metre radius. The pheromone lure attracts and traps male moths disrupting breeding and reducing infestation. Use your second lure and sticky glue insert to complete the season. Traps are made of strong, rigid, corrugated plastic so they can be removed at harvest for use next season with a NoPests® Codling Moth Pheromone Refill Kit.. The codling moth is 8mm (5/16) long, grey, with black lines and a distinctive copper patch on the wing tips. Maggot damage in apples and pears is mainly caused by caterpillars of the codling moth. Female moths lay eggs on leaves and fruits. The eggs hatch after 10-14 days and caterpillars bore into the fruitlets carving galleries inside.. ...

Madison, WI 53718. Dane County Parks, the Wisconsin Department of Natural Resources, and the Dane County Tree Board will hold a public information forum about the 2011 Gypsy Moth Suppression Program in Dane County on February 2, 2011. The meeting will be held at 7:00 pm at the Lyman Anderson Agriculture and Conservation Center, 1 Fen Oak Court, Madison WI 53718. Representatives from the three agencies will provide information on the biology and life cycle of the gypsy moth and discuss gypsy moth management and control. Questions from the public will be welcomed.. The gypsy moth population is down statewide and in Dane County. However, there are still certain locations within the County that have similar or higher populations than last year. The gypsy moth can be a serious tree pest. In large populations, gypsy moths can defoliate trees and kill those that are already under stress. In addition, some people experience allergic reactions caused by contact with gypsy moth egg cases or caterpillars. ...

The control of Indianmeal moth [Plodia interpunctella (Hübner)], a commonly found serious stored product pest around the world, relies mainly upon chemical control methods. Because of recent changes in the laws and regulations governing pesticide usage in the United States, there is an increasing need for finding safer chemicals to control insect pests. Hydroprene, an insect growth regulator, is considered to be a safe alternative. In this study, I quantified the effects of hydroprene on two critical life stages of Indianmeal moth, the eggs and 5th instar wandering phase larvae. Maximum development time in the untreated controls was 13.6 ± 0.6 d at 16°C and minimum development time was 2.3 ± 0.4 d at 32°C. At 20°C and 24°C, the effect of hydroprene on egg development became more evident; development time generally increased with exposure interval, with some variability in the data. The mean egg mortality among all temperatures was 7.3 ± 4.6%. Among the treatments, mortality of eggs ...

Flight of the adult codling moths starts near the beginning of May with the eclosion of second generation moths and stops around the end of August as the first generation moths reach senescence every year. The first and second generation flight period overlap anywhere from 10 to 20 days. Overlap of second and first generation moth flight period means there will be continuous damage done by the codling moth during the summer months.[1] Adult moths are generally sedentary and tend to spend the day resting on leaves or branches. Such limited mobility is not because they are incapable of long-distance flight; they have the capacity to travel up to several kilometers.[9] However, the majority of the moths travel between 60 and 800m.[1] Only about 10% of the population are long-distance travelers.[10] Such wide range of flight behavior is an adaptive characteristic; their habitat is usually determined by the availability of the fruit, so there is normally no need to travel far, but if the fruits are ...

Investigations on assessment of insecticide resistance in diamondback moth, Plutella xylostella, Linnaeus on cabbage were undertaken at Department of Agricultural Entomology, Post Graduate Institute, MPKV, Rahuri during 2011-2013. Insecticide usage pattern in Ahmednagar, Dhule, Pune and Nashik locations against diamondback moth on cabbage was also studied. Survey results indicated that farmers relied mostly on chemical insecticides to control the diamondback moth on cabbage. The insecticides viz., chlorpyriphos, quinalphos, profenophos, cypermethrin, lambda-cyhalothrin, flubendiamide and chlorantraniliprole were the most widely used for its control. It was also observed that the most cabbage growers from all four locations followed routine or calendar spraying pattern. Majority of the farmers did sprayings at an interval of 6 to 10 days giving maximum 6 to 8 sprays. Toxicity of certain conventional insecticides against P. xylostella in western Maharashtra was studied. The populations collected ...

Microbial diseases cause considerable economic losses in aquaculture and new infection control measures often rely on a better understanding of pathogenicity. However, disease studies performed in fish hosts often require specialist infrastructure (e.g., aquaria), adherence to strict legislation and do not permit high-throughput approaches; these reasons justify the development of alternative hosts. This study aimed to validate the use of larvae of the greater wax moth (Galleria mellonella) to investigate virulence of the important fish pathogen, Vibrio anguillarum. Using 11 wild-type isolates of V. anguillarum, these bacteria killed larvae in a dose-dependent manner and replicated inside the haemolymph, but infected larvae were rescued by antibiotic therapy. Crucially, virulence correlated significantly and positively in larva and Atlantic salmon (Salmo salar) infection models. Challenge studies with mutants knocked out for single virulence determinants confirmed conserved roles in larva and fish

2016 by the authors; licensee MDPI, Basel, Switzerland. Studies were conducted in commercial apple orchards in British Columbia, Canada, to determine whether lures combining ethyl-(E,Z)-2,4-decadienoate, pear ester (PE), with either acetic acid (AA) or sex pheromone, (E,E)-8,10-dodecadien-1-ol (codlemone), might improve monitoring of codling moth, Cydia pomonella (L.), in an area-wide programme integrating sterile insect technology (SIT) and mating disruption (MD). Catches of sterile and wild codling moths were compared in apple orchards receiving weekly delivery of sterile moths (1:1 sex ratio) using white delta traps baited with either AA or PE alone, and in combination. Sterile and wild codling moths responded similarly to these kairomone lures. For each moth sex and type (sterile and wild), AA-PE lures were significantly more attractive than AA or PE alone. Bisexual catches with AA-PE lures were compared with those of commercial bisexual lures containing 3 mg of codlemone plus 3 mg of PE ...

While Hyalophora cecropia larvae are large and feed on a wide range of host plants, this species is not considered a serious pest in any parts of its range. Some populations of Hyalophora cecropia may be in decline due to a number of factors, including nontarget effects of introduced biological control agents. Boettner et al. (2000) suggested that the generalist parasitoid fly Compsilura concinnata (Diptera: Tachinidae) may be responsible for such declines in the northeastern U.S. Due to its size and hardiness, Hyalophora cecropia has been used extensively in physiological and biochemical research. Carroll Williams conducted pioneering work on juvenile hormone and its role in molting and metamorphosis using this species. Owing to its impressive size and appearance, Hyalophora cecropia has become a favorite of collectors and amateur Lepidopterists. Eggs and pupae are commercially available, and a small livestock industry has developed around this and other related species. ...

The superior hearing of the greater wax moth [Galleria mellonella] is helping researchers advance sound technology. How did a moth get such abilities?

0032] In yet another embodiment, the insect pests are of the order Lepidoptera, such as Achoea janata, Adoxophyes spp., Adoxophyes orana, Agrotis spp. (cutworms), Agrotis ipsilon (black cutworm), Alabama argillacea (cotton leafworm), Amorbia cuneana, Amyelosis transitella (navel orangeworm), Anacamptodes defectaria, Anarsia lineatella (peach twig borer), Anomis sabulifera (jute looper), Anticarsia gemmatalis (velvetbean caterpillar), Archips argyrospila (fruittree leafroller), Archips rosana (rose leaf roller), Argyrotaenia spp. (tortricid moths), Argyrotaenia citrana (orange tortrix), Autographa gamma, Bonagota cranaodes, Borbo cinnara (rice leaf folder), Bucculatrix thurberiella (cotton leafperforator), Caloptilia spp. (leaf miners), Capua reticulana, Carposina niponensis (peach fruit moth), Chilo spp., Chlumetia transversa (mango shoot borer), Choristoneura rosaceana (obliquebanded leafroller), Chrysodeixis spp., Cnaphalocerus medinalis (grass leafroller), Colias spp., Conpomorpha cramerella, ...

The Geometer Moths are the second largest family of moths in North America. This family includes many serious agricultural and forest pests. These moths are small to medium in size, with slender bodies and broad wings. On average, the wingspan of these moths is 1-6 cm, though the females of some species lack wings entirely. Larvae are usually twiglike and lack the first 2-3 pairs of prolegs. They move by extending the front of the body as far forward as possible, then bringing the rear of the body up to meet it; this is how they have gotten the name inchworm or measuringworm. Larvae usually feed externally on leaves and pupate in loose cocoons in leaf litter or soil.. ...

This is an exciting photo for us since we get so many requests to identify White Marked Tussock Moth Caterpillars, Orgyia leucostigma. The female Tussock Moth is flightless and lays a foamy mass of eggs. This image agrees with one posted on BugGuide. ...

Estimating the population level of codling moth in commercial orchards is challenging. Visual observation of fruit injury can provide valuable information about the level and distribution of codling moth in an orchard. See the discussion above for information on this method. If fruit injury monitoring reveals injury levels of 0.5% or more then increased controls should be implemented.. Capture of codling moth adults in pheromone traps can be used to estimate population levels and help make control decisions. The number of traps used, their location, trap maintenance and the quality of the pheromone trap are all critical elements to the successful use in a threshold-based decision program.. To implement a threshold-based decision program it is essential to use one monitoring trap for every 2.5 acres. Traps should be placed in the orchard before the accumulation of 175 degree-days (or at the pink stage of apple bud development). Trap placement within the orchard and tree will influence moth ...

We have received Issue 5 - July 2021 update from the Forestry Commission on the Oak Processionary Moth The Forestry Commission encourage you to report any OPM sightings which you can do so via their TreeAlert website.

Bats and moths are intertwined in a predator-prey relationship that has spanned at least 50 million years (Miller and Surlykke, 2001). In response to the heavy predation pressure of echolocating bats, many moths have evolved simple ears that alert them to the danger of attack and initiate unpredictable evasive maneuvers (Roeder, 1967). Tiger moths (superfamily Noctuoidea, subfamily Arctiinae) also produce ultrasonic clicks whose defensive functions vary depending on the acoustic and chemical properties of the moth species. Most species produce short bursts of clicks that maximally occupy 1-12% of time with sound (Corcoran et al., 2010). These low-duty-cycle clicks are well suited for advertising the toxic chemistry many tiger moths acquire as caterpillars (Hristov and Conner, 2005a; Hristov and Conner, 2005b; Nishida, 2002; Ratcliffe and Fullard, 2005). After bats learn this aposematic association, they can be misled by palatable tiger moths that mimic their chemically defended relatives (Barber ...

Our horticulturist found this Luna Moth (Actias luna) caterpillar feeding on the leaves of a river birch tree. He placed his hand behind the caterpillar for scale. The Luna Moth lays its eggs on a variety of deciduous trees including walnut, beech, persimmon, and hickory. Within two weeks, caterpillars hatch from the eggs to begin feeding. The caterpillar will go through a series of molts before reaching its largest size, about 2 ½ inches. Once the Luna Moth caterpillar has fed enough to reach this size, it spins a dark brown, silken cocoon in leaf litter laying on the ground. After a few weeks, the winged adult Luna Moth emerges as a beautiful, large, nocturnal moth with stunning pale green wings, pure white body, and two wavy tails (actually extensions of the wings). Adult Luna Moths can have a wingspan of four inches, and they lack mouthparts. The Luna Moths fly in spring and summer, never eating as adults, and instead serve the sole purpose of reproducing. Luna Moth females emit ...

After over-wintering as a fully-grown caterpillar in a cocoon, usually under the bark of a host tree, moths hatch out early to mid-October. Peak emergence is in early to mid-December.. After mating, the first generation female moth lays eggs inside flowers. Later generations lay eggs within a few centimetres of developing fruit. Newly hatched grubs locate fruit and bore in towards the centre to feed on the developing seeds. The grubs then burrow out of the fruit as they (the grubs) near maturity. Telltale signs include lots of frass (reddish-brown droppings). Grubs then pupate for a few weeks when adults moths again hatch out. Later in the season cocoons remain dormant to over-winter.. Codling Moth can complete up to three life-cycles during a single season in Australia depending on location and weather considerations so monitoring of moth numbers should occur from flowering until mid-summer.. ...

The Secret World of Moths is a magical journey to the world of moths. Using 3D X-ray tomography we shed light to their hidden macrocosm and explore their way of life in an unprecedented way. Geograp hically the film spans from the Arctic Circle to the Equator. Observing these two extreme environments helps us learn about and understand the diversity and complexity of their macroscopic world and our fragile existence on planet Earth. The secret world of moths through the eyes of a scientist Moths are a highly diverse group of insects. In terms of species richness among all animal groups, m oths come second only to beetles. Moths and butterflies belong to the same order, Lepidoptera, but the vast majority of all lepidopterans are indeed moths. Despite their abundance, moths have not at tracted much attention and they may seem like an odd choice for a film. However, filmmakers Hannes Vartiainen and Pekka Veikkolainen show that moths do have fascinating tales to tell. This film pre sents stunning ...

Some moths, particularly their caterpillars, can be major agricultural pests in many parts of the world. Examples include corn borers and bollworms.[5] The caterpillar of the gypsy moth (Lymantria dispar) causes severe damage to forests in the northeastern United States, where it is an invasive species. In temperate climates, the codling moth causes extensive damage, especially to fruit farms. In tropical and subtropical climates, the diamondback moth (Plutella xylostella) is perhaps the most serious pest of brassicaceous crops. Also in sub-Saharan Africa, the African sugarcane borer is a major pest of sugarcane, maize, and sorghum.[6] Several moths in the family Tineidae are commonly regarded as pests because their larvae eat fabric such as clothes and blankets made from natural proteinaceous fibers such as wool or silk.[7] They are less likely to eat mixed materials containing some artificial fibers. There are some reports that they may be repelled by the scent of wood from juniper and cedar, ...

Ears evolved in many groups of moths to detect the echolocation calls of predatory bats. Although the neurophysiology of bat detection has been intensively studied in moths for decades, the relationship between sound-induced movement of the noctuid tympanic membrane and action potentials in the auditory sensory cells (A1 and A2) has received little attention. Using laser Doppler vibrometry, we measured the velocity and displacement of the tympanum in response to pure tone pulses for moths that were intact or prepared for neural recording. When recording from the auditory nerve, the displacement of the tympanum at the neural threshold remained constant across frequencies, whereas velocity varied with frequency. This suggests that the key biophysical parameter for triggering action potentials in the sensory cells of noctuid moths is tympanum displacement, not velocity. The validity of studies on the neurophysiology of moth hearing rests on the assumption that the dissection and recording ...

Although several insect species have developed resistance toB. thuringiensis formulations or toxins (30), there are only three reported species for which resistant strains can survive on transgenic insecticidal plants. Survival to maturity has been reported for resistant strains of diamondback moth on B. thuringiensis-transgenic broccoli and B. thuringiensis-transgenic canola (17, 22, 38) and for tobacco budworm (Heliothis virescens) and pink bollworm (Pectinophora gossypiella) on B. thuringiensis-transgenic cotton (6, 13). However, in all these reports the resistant strains did not develop directly from selection on B. thuringiensis-transgenic crops.. After 24 generations of selection with the Cry1C protoxin or transgenic broccoli expressing a Cry1C protein, the Cry1C resistance in our diamondback moth strain was so high that neonates could complete their entire life cycle on transgenic broccoli expressing high levels of Cry1C. This contrasts with the F1 progeny, for which the mortality of all ...

Asian Gypsy Moth. Asian gypsy moths (AGM, including Lymantria dispar asiatica, Lymantria dispar japonica, Lymantria albescens, Lymantria umbrosa, Lymantria postalba) are exotic pests not known to occur in the United States. Although in many ways similar to the European gypsy moth subspecies, AGM larvae have been known to feed collectively on over 500 plant species, covering over 100 botanical families. In addition, female AGM are active flyers that can be capable, in some cases, of flying up to 25 miles (40 km). This broad range of possible host plants combined with the females ability to fly could allow AGM to spread rapidly into and through uninfested areas. Large infestations of AGM can completely defoliate trees, weakening the trees and leaving them more susceptible to disease. If defoliation is repeated for two or more years, it can lead to the death of large sections of forests, orchards and landscaping. An introduction into the US would pose a major threat to the landscape of the North ...

Antheraea mylitta cytoplasmic polyhedrosis virus (AmCPV), a cypovirus of Reoviridae family, infects Indian non-mulberry silkworm, Antheraea mylitta, and contains 11 segmented double stranded RNA (S1-S11) in its genome. Some of its genome segments (S2 and S6-S11) have been previously characterized but genome segments encoding viral capsid have not been characterized. In this study genome segments 1 (S1) and 3 (S3) of AmCPV were converted to cDNA, cloned and sequenced. S1 consisted of 3852 nucleotides, with one long ORF of 3735 nucleotides and could encode a protein of 1245 amino acids with molecular mass of ~141 kDa. Similarly, S3 consisted of 3784 nucleotides having a long ORF of 3630 nucleotides and could encode a protein of 1210 amino acids with molecular mass of ~137 kDa. BLAST analysis showed 20-22% homology of S1 and S3 sequence with spike and capsid proteins, respectively, of other closely related cypoviruses like Bombyx mori CPV (BmCPV), Lymantria dispar CPV (LdCPV), and Dendrolimus punctatus CPV

Your photo arrived at a very timely moment. It is the end of the month, and it is time for us to select a new Bug of the Month for October, and your Buck Moth, Hemileuca maia, gets that honor. Your sighting is also right on time for the Buck Moths seasonal appearance. According to BugGuide they fly October-November, only to September in north, to December in Florida. That coincides with buck hunting season in many parts of the country, hence the common name. We imagine that Buck Moth are seen flying in the woods when hunters are out trying to bag that trophy. We frequently post photos of Buck Moth Caterpillars in the summer, but folks should be warned that they have stinging spines. The Buck Moth Caterpillars feed on the leaves of oak trees. The Buck Moth genus contains other species, including some that are found in the west, like the Elegant Sheep Moth, but your species has only been reported as far west as Texas, and from Canada in the north to Florida in the south. Like other members of ...

Activities of superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GSH-Px), glutathione reductase (GR), glutathione-S-transferase (GST), as well as total glutathione (tGSH) concentration were analyzed in the hemolymph and fat body of the European corn borer Ostrinia nubilalis Hubn. and the Mediterranean borer Sesamia cretica Led. (Lepidoptera, Noctuidae). Controls were maintained at 8°C while experimental groups of larvae were exposed to -3°C for ten days and then to -12°C for 23 days (only for Ostrinia). Cold exposure significantly increased fat body SOD, GR, and GST activities of Ostrinia larvae. Only GST activity and tGSH levels increased significantly in Ostrinia larval hemolymph on cold exposure. In Sesamia larvae after cold exposure, hemolymph CAT activity was significantly lower, while fat body tGSH increased. The antioxidant defense systems of these two species show differences, probably influenced by their respective cold-hardiness metabolism. According to its ...

In this game, your kids can simulate how bats use echolocation to catch moths and other insects. (For more about echolocation, see Ears in the Dark in Ranger Ricks NatureScope Amazing Mammals-Part II.) To play, have the kids form a circle about 10-15 feet (3-4.5 m) across. Choose one member of the group to play the role of a bat. Blindfold the bat and have him or her stand in the center of the circle. Then designate three to five other children as moths and have them also come to the center. The object of the game is for the bat to try to tag as many moths as possible. Both the bat and moths can move, but they must stay within the circle. (Once a moth is tagged, he or she should go outside the circle and sit down.) Whenever the bat calls out bat, the moths have to respond by calling back moth. Tell the moths that every time they hear the bat call bat, it simulates the bat sending out an ultrasonic pulse to see whats in its path. The pulse bounces back to the bat, simulated by the ...

The Gypsy Moth - Life Cycle and Related Moths Abstract: A summary of the life cycle of the gypsy moth and a listing of a few related moths.

All the traps, for recording moths, have a mercury vapour bulb but you can use a bright light with a white sheet. We have a Robinsons trap, which we use approximately two to three times a month, never more than once a week as you are at risk of trapping the same moths. The best months for species and quantity are in the summer, with most of the beautiful hawk moths in June and July. There are only a few moths in the winter.. Encouraging moths to the garden with a wide variety of flowers and plants will also encourage other important insects like butterflies and bees.. For identification we use the Field Guide to the Moths of Great Britain and Ireland by Paul Waring and Martin Townsend, illustrated by Richard Lewington. It is not always easy to sex the moths without looking at their genitalia - this is beyond our ability! We keep a record of all we see and send the results to the Wiltshire Moth Recorder, which we have been doing for the last five years. If we are in any doubt, there is always ...

Pseudomonas aeruginosa is an opportunistic pathogen associated with life-threatening nosocomial and community-acquired infections. Antibiotic resistance is an immediate threat to public health and demands an urgent action to discovering new antimicrobial agents. One of the best alternatives for pre-clinical tests with animal models is the greater wax moth Galleria mellonella. Here, we evaluated the antipseudomonal activity of silver nanoparticles (AgNPs) against P. aeruginosa strain UCBPP-PA14 using G. mellonella larvae. The AgNPs were synthesized through a non-toxic biogenic process involving microorganism fermentation. The effect of AgNPs was assessed through characterization and quantification of the hemocytic response, nodulation and phenoloxidase cascade. On average, 80% of the larvae infected with P. aeruginosa and prophylactically treated with nanoparticles survived. Both the specific and total larvae hemocyte counts were restored in the treated group. In addition, the nodulation process and the

Citation: N/A Interpretive Summary: Technical Abstract: Phytoalexins are inducible biochemicals that locally protect plant tissues against biotic attack. Due to their agronomic significance, maize and rice have been extensively investigated for their terpenoid-based defenses which include insect-inducible monoterpene and sesquiterpene volatiles. Rice also produces a complex array of non-volatile pathogen-inducible terpenoid phytoalexins; however, until recently analogous pathways in maize were unknown. We recently discovered the existence of a complex series of sesquiterpene and diterpene phytoalexins in maize stalks following attack by the European corn borer (Ostrinia nubilalis) and pathogenic fungi. The predominant acidic sesquiterpene and diterpene phytoalexins, termed zealexins and kauralexins, are likely derived from ß-macrocarpene and ent-kaur-15-ene, respectively. Following induction, the predicted volatile terpenoid precursors exist at relatively low levels compared to the oxygenated ...

The nocturnal Bogong moth (Agrotis infusa) is a well-known Australian insect that has a remarkable migratory ability. Like the Monarch butterflies of North America, Bogong moths make a yearly migration over enormous distances from southern Queensland to the alpine regions of New South Wales and Victoria. After emerging from their pupae in early Spring, many millions of adult Bogong moths embark on their long southward nocturnal journey towards the Australian Alps where they seek out the cool shelter of selected and isolated high ridge-top caves and rock crevices, spending the summer months there in a dormant state. Towards the end of the summer (February and March), the moths emerge and begin their long return trip northwards to their breeding grounds in Queensland. Once there, moths mate, lay eggs and die. The moths that hatch in the following Spring then repeat the migratory cycle afresh. Despite having had no previous experience of the migratory route, these moths remarkably find their way to ...

The attraction of the codling moth, Cydia pomonella, to apple volatile compounds known to elicit an antennal response was tested both in the field and in a wind tunnel. In the field, (E)-beta-farnesene captured male moths. The addition of other apple volatiles, including (E,E)-alpha-farnesene, linalool, or (E,E)-farnesol to (E)-beta-farnesene did not significantly augment trap catch. Few females were caught in traps which also caught male moths, but female captures were not significantly different from blank traps. In the wind tunnel, males were attracted to (E,E)-farnesol, but not to (E)-beta-farnesene. The addition of (E,E)-alpha-farnesene to (E)-beta-farnesene had a synergistic effect on male attraction. The male behavioural sequence elicited by plant volatiles, including upwind flight behaviour, was indistinguishable from the behaviour elicited by sex pheromone.. ...

Flown for the first time on October 26, 1931, the Tiger Moth was derived from the DH 60 Moth. The Moth design, with the fuel tank directly above the front cockpit, restricted cockpit access for air force pilots wearing a parachute. The solution was to move the upper wing forward and sweep the wings back for correct positioning of the centre of lift. Initially the DH 82 was powered by a 120 hp Gipsy III engine, but the DH 82A received the 130 hp Gipsy Major. More than 1,000 Tiger Moths were delivered before World War 2, and subsequently 4,005 were built in the U.K. and shipped all over the world; 1,747 were built in Canada between 1938 and 1942, 1,085 in Australia and 345 in New Zealand.. The first Canadian-produced Tiger Moth flew in December 1937, with some being powered by the Menasco engine. The majority were DH 82Cs, powered by the 140 hp DH Gipsy Major 1C engine and with enclosed cockpits, cockpit heaters, brakes and tail wheels. Other changes to make them more suitable for operation in ...

The annual High Park moth night was held on Thursday, July 23, 2020. Due to the COVID-19 situation, this years event was co-sponsored by only High Park Nature and the High Park Moth Study group and had a restricted number of participants, all of whom are regular members of the moth study group. The weather was clear and warm, very conducive to a productive session.. A total of 135 species of moths were identified, including 4 new for the High Park Moth Study, bringing the studys all-time total to 1028 species! This citizen science project began in 2016 and broke through the 1000 species mark earlier this season. For more about the study, see Meet the Mothia, in the Toronto Star.. This years moth night also brought out a good variety of other insects, particularly leafhoppers and small beetles.. High Park, Toronto is a large urban park (161 ha, about 400 acres) with diverse habitats including a globally rare black oak savannah. For more information about the park see highparknature.org.

Ian Sims came out yesterday to do a bit of light trapping and, even though it was set to be one of the hottest days of the year, he thought it was worth also bringing clearwing moth pheromones to see if we could lure in some of these incredibly elusive moths. They are very rarely seen because they do not come to light and are day-flying around their food plants. They look like little wasps so are very hard to spot - unless you happen to have a set of the moths pheromones.. It turned out to be much easier than I thought and within 30 minutes we had an Orange-tailed Clearwing (Synanthedon andrenaeformis) from Wayfairing Tree and then on an old Crab Apple we caught a Red-belted Clearwing (Synanthedon myopaeformis) too! I had always wondered if we still had the Orange-tailed because Id been shown the marks on Wayfairing Tree bark caused by the larvae by Brian Baker many years ago but never seen a moth in my life. The light trapping didnt disappoint either with 212 species seen during the day and ...

BioAssay record AID 1082680 submitted by ChEMBL: Insecticidal activity against Plutella xylostella (diamondback moth) third-instar larvae measured 24 hr post dose by leaf disk dipping assay.

There are several lesser wax moth management options for beekeepers. The most important aspect of managing lesser wax moths is to maintain healthy, robust honey bee colonies. Strong hives seldom have issues with moths and other secondary pests because worker bees kill and/or evict lesser wax moth larvae and seal areas where adult moths may lay eggs.. In contrast, lesser wax moths can cause significant damage to stored wax combs. Fortunately, there are several ways to store wax comb to limit lesser wax moth damage. Either extreme heat or cold will kill all life stages of lesser wax moths, including eggs that may be hidden from view. It is possible to kill lesser wax moths at temperatures of 114°F and above, noting that wax comb melts at 119°F. Freezing is a better choice for treating wax combs. All lesser wax moth stages will die when maintained at 20°F for 24 to 48 hours. After freezing, the materials can be stored in airtight plastic bags to prevent re-infestation. Cold rooms maintained at ...

1. The effects of host-plant resistance on the population dynamics of the Diamondback moth, Plutella xylostella L., and its solitary parasitoid, Cotesia plutellae (Kurdjumov), were studied in replicated time-series experiments. 2. Host-plant resistance did not affect the equilibrial abundance of the Diamondback moth, but it affected the dynamics of Diamondback moth populations. 3. The mean population size of Diamondback moth showed no significant difference between Brassica rapa (a susceptible host plant) and Brassica napus (a partially resistant host plant) either in the presence or absence of the parasitoid. 4. Time-series analysis suggests that the dynamics of Diamondback moth on B. rapa were underpinned by delayed density-dependent processes. In contrast, the dynamics of the moth on B. napus were influenced by a direct density-dependent process. 5. Although measures of short-term parasitism showed a significantly higher rate of parasitism by C. plutellae on Diamondback moth feeding on B. napus

TY - JOUR. T1 - Diamondback moth, Plutella xylostella (L.) in Southern Africa. T2 - Research trends, challenges and insights on sustainable management options. AU - Machekano, Honest. AU - Mvumi, Brighton M.. AU - Nyamukondiwa, Casper. PY - 2017/1/1. Y1 - 2017/1/1. N2 - The diamondback moth (DBM), Plutella xylostella, is a global economic pest of brassicas whose pest status has been exacerbated by climate change and variability. Southern African small-scale farmers are battling to cope with increasing pressure from the pest due to limited exposure to sustainable control options. The current paper critically analysed literature with a climate change and sustainability lens. The results show that research in Southern Africa (SA) remains largely constrained despite the regions long acquaintance with the insect pest. Dependency on broad-spectrum insecticides, the absence of insecticide resistance management strategies, climate change, little research attention, poor regional research collaboration ...

A moth is an insect closely related to the butterfly. Both are of the order Lepidoptera. The division of lepidopterans into moths and butterflies is a popular, not a scientific distinction. While butterflies are considered to be a natural group-having descended from a single common ancestor-moths are an artificial group, defined as any lepidopteran that is not a butterfly. However, neither hold formal taxonomic rank.. Popularly defined, most species of Lepidoptera are moths, and about 70 of the 80 families of the order. Butterflies can be considered to be a small group that arose from within the moths.. In general, moths are considered to be distinct from butterflies in that moths are chiefly nocturnal, while butterflies are diurnal; moths have comb-like or feathery antennae while butterflies have thin, slender, and filamentous antennae; and moths have a stouter and more furry-looking body, duller coloring, and proportionately smaller wings than butterflies. However, there are many exceptions ...

The pomegranate fruit moth, Ectomyelois ceratoniae Zeller (Lep.: Pyralidae), is the major pest ofpomegranate orchards in Iran. Insect sex pheromone traps, were used to determine the populationdensity of pest in this study, the efficacy of sex pheromone traps, including trap type, height and color oftrap and trap situation. For this purpose, experiments were conducted in a randomized complete blockdesign with four replications in the Lorestan province. The results showed that, the delta type trap was thebest, so it was captured 1.04 moth/day. The comparison of trap heights showed that, height 1.5 meter hasthe maximum capture (1.24 moth/day). The study on trap color and situation showed that, white colorand south situation were captured the highest moth (1.17 and 1.04 moth/day, respectively). As a result,the most suitable conditions for the usage of synthetic pheromone trap of pomegranate fruit moth, deltatypetrap with color white and set in the pomegranate trees south and 1.5 meter ...

Moth and butterfly are common names given to insects of the order Lepidoptera. There is no strong scientific basis for these terms. There is an evolutionary continuum from the most ancient moth group to the most sophisticated butterfly group. Some moths are more closely related to butterflies than to other moths.. There are some general differences between moths and butterflies. Moths usually hold their wings flat while resting, have feathery antennae, and are active at night. Butterflies tend to be more brightly coloured, have clubbed antennae, hold their wings erect while at rest, and are active by day. But there are exceptions to these generalisations. Many New Zealand moths fly during the day or at dusk. The black mountain ringlet butterfly holds its wings flat while at rest. Some New Zealand butterflies are drab, and most people would call them moths. One sure way to distinguish the two in New Zealand (this does not apply globally) is that all native butterflies have clubbed ...

Glutathione S-transferases (GSTs) are multifunctional detoxification enzymes that play important roles in insects. The completion of several insect genome projects has enabled the identification and characterization of GST genes over recent years. This study presents a genome-wide investigation of the diamondback moth (DBM), Plutella xylostella, a species in which the GSTs are of special importance because this pest is highly resistant to many insecticides. A total of 22 putative cytosolic GSTs were identified from a published P. xylostella genome and grouped into 6 subclasses (with two unclassified). Delta, Epsilon and Omega GSTs were numerically superior with 5 genes for each of the subclasses. The resulting phylogenetic tree showed that the P. xylostella GSTs were all clustered into Lepidoptera-specific branches. Intron sites and phases as well as GSH binding sites were strongly conserved within each of the subclasses in the GSTs of P. xylostella. Transcriptome-, RNA-seq- and qRT-PCR-based analyses

Members of this wasp species primarily attack tobacco budworms and related caterpillars. These detrimental moth caterpillars attack not only tobacco, as suggested by the common name, but also soybeans and cotton, along with many other plant species. These two crops are particularly important to the Louisiana agricultural economy, making their natural enemies important in integrated pest management of pest species. Tobacco budworms and related species of noctuid moths are among the most important of these crop pests based on a number of classical life history studies and results of current research. Because of the narrow host specificity of tobacco budworm parasitoids, several species of these wasps are important to the natural control of tobacco budworm populations. Releases of tobacco budworm parasitoids in tobacco fields have been shown to be highly effective, and wasp rearing and release programs have great potential for improving pest management of these pests in many parts of the world. ...

Hemolymph coagulation stops bleeding and protects against infection. Clotting factors include both proteins that are conserved during evolution as well as more divergent proteins in different species. Here we show that several silk proteins also appear in the clot of the greater wax moth Galleria mellonella. RT-PCR analysis reveals that silk proteins are expressed in immune tissues and induced upon wounding in both Galleria and Ephestia kuehniella, a second pyralid moth. Our results support the idea that silk proteins were co-opted for immunity and coagulation during evolution.. ...

On the market since 1996, genetically modified plants expressing an insecticidal toxin (Cry toxin stemmed from Bacillus thuringiensis) target several lepidopteran and coleopteran pests. In this study, we assessed the impact of two varieties of Bt maize producing different toxins (Cry1Ab or Cry1Fa, respectively) on the biology of a storage pest: Plodia interpunctella (Hübner) (Lepidoptera: Pyralidae). The Indianmeal moths were susceptible to both toxins but showed an escape behavior only from Cry1Fa. The weight of females issued from larvae reared on Cry1Ab increased with increasing toxin concentration, but adults of both sexes reared on Cry1Fa had decreased weight. Both toxins increased development time from egg to adult regardless of sex and had no impact on the male adult lifespan. Finally, we recorded a time lag between metamorphosis from the non-Bt and the Bt diets, which increased proportionally to Cry concentration in the Bt diet.

ISHS III International Symposium on Horticultural Crop Wild Relatives Insecticidal properties of bastard oleaster (Elaeagnus latifolia) extracts against diamondback moth (Plutella xylostella)

Galleria mellonella larvae were inoculated with different doses of β-glucan by injection into the haemocoel. Those larvae that had received high doses of β-glucan (15, 30 or 60 μg/larva) demonstrated increased survival following infection with the yeast Candida albicans. High concentrations of glucan induced an increase in haemocyte density and a reduction in yeast proliferation within the haemocoel. Proteomic analysis of glucan-treated larvae revealed increased expression of a variety of peptides some of which may possess antimicrobial properties. Analysis of expression profiles revealed that low doses of β-glucan (3.75 μg/larva) triggered the increased expression of certain peptides (e.g. hemolin) while high dose inoculation was required before the increased expression of others (e.g. archaemetzincin) was evident. These results indicate that low doses of β-glucan induce a limited immune response while high doses induce an immune response that has the potential to curtail the threat ...

The focus of this study was to reconstruct a phylogenetic hypothesis for the moth subfamily Arctiinae (tiger moths, woolly bears) to investigate the evolution of larval and adult pharmacophagy of pyrrolizidine alkaloids (PAs) and the pathway to PA chemical specialization in Arctiinae. Pharmacophagy, collection of chemicals for non-nutritive purposes, is well documented in many species, including the model species Utetheisa ornatrix L. A total of 86 exemplar ingroup species representing tiger moth tribes and subtribes (68 genera) and nine outgroup species were selected. Ingroup species included the most species-rich generic groups to represent the diversity of host-plant associations and pharmacophagous behaviors found throughout Arctiinae. Up to nine genetic markers were sequenced: one mitochondrial (COI barcode region), one nuclear rRNA (D2 region, 28S rRNA), and seven nuclear protein-coding gene fragments: elongation factor 1-α protein, wingless, ribosomal protein subunit S5, carbamoylphosphate

The relationship between the yucca moth (Genus: Tegeticula) and yucca plant (Genus: Yucca) is believed to have begun at least 40 million years ago and is one of the most cited examples of co-evolution. The yucca plant requires pollination by the yucca moth and moth larvae, in turn, require developing yucca seeds for food - a relationship known as an obligate mutualism. This is actually one of the few documented cases of active pollination because the moth purposefully places pollen on the plants stigmas. The female yucca moth has specially adapted mouth-parts used for pollen handling. The moth drags its tentacles across the yuccas anthers and collects a large amount of pollen, which the moth then forms into a sticky ball and carries it between its tentacles and thorax. This pollen ball is very large - often made of nearly 10,000 grains of pollen - and can constitute up to 10% of the moths weight. After collecting the pollen ball, the moth flies to a different yucca plant to deposit its eggs. ...

Use Trichogramma spp., a moth egg parasite that prevents caterpillars from emerging by laying their eggs in the moth eggs, killing them. Timing the release is important - if you release too early there arent enough pest eggs for the wasps to parasitize - too late means that the pest eggs have hatched and you have a new problem - caterpillar pests. Biology & Life Cycle: Trichogramma wasps lay their eggs inside the pest eggs, stopping development. The larvae feed on the egg and then emerge as adults. The larvae take 10 days to develop within the pest moth egg, which turns brown or black as the larvae pupate. The adult wasps live anywhere from 7 to 14 days, depending on temperature and moisture and the female Trichogramma will parasitize up to 300 pest moth eggs. Eggs on cards usually hatch within 2-5 days. Preferred food: Trichogramma parasitize the eggs of more than 200 pests, including borers, webworms, loopers, leafworms, fruitworms, cutworms, bollworms, and armyworms (except beet armyworms).

This study shows that the upwind flight of male H. armigera moths towards different odour sources is strongly influenced by previous odour experience. In wind tunnel dual-choice bioassays, moths that were fed in the presence of a single volatile showed a preference for that odour compared with a second volatile that they had not experienced. Moths with no experience of the volatiles did not differ in their relative preferences for either odour source from those exposed to volatiles without association with a food reward. The results demonstrate that associative conditioning influences preferences for host odours in foraging moths. Studies on the proboscis extension reflex (PER) in H. armigera have looked more closely at the nature of the pairing in this type of learning (Hartlieb, 1996).. Moths flew upwind to both odours in the absence of conditioning, which implies that an innate attraction to these odours exists. An innate preference for phenylacetaldehyde over α-pinene was demonstrated in ...

Entomologists had actually been aware of the two new moth species since at least the early 1980s, referring to them informally and unofficially as Maunakea flying moths. However, there was no single scientist with the time and expertise to describe the species in a complete and cohesive way alongside other Hawaiian moths of the same genus.. Prestes, who was a graduate student at UH Mānoa in Rubinoffs insect systematics and biodiversity lab, would observe the moths flying around during the daytime while conducting research on closely related moths. It was only recently that the UH Hilo scientists and their colleagues were able to come together to produce an official taxonomic description.. There are not enough specialists and taxonomists in Hawaiʻi, explains Eiben. Also, you really need a team to describe the species and how its connected to the high elevation ecosystems arthropod biodiversity baseline. There are just too many species for one entomologist to do it alone. Thats why Matt ...

Larvae of Galleria mellonella, the greater wax moth, provide an alternative infection model for many human pathogens as they are amenable to use at elevated incubation temperatures (37 °C). This study and a parallel study by Mukherjee et al. [Mukherjee, K., Altincicek, B., Hain, T., Domann, E., Vilcinskas, A. & Chakraborty, T. (2010). Appl Environ Microbiol 76, 310-317] establish this insect host as an appropriate model to investigate the pathogenesis of Listeria species. In this study we show that inoculation with Listeria monocytogenes initiates a dynamic infection in G. mellonella and that production of the cytolysin listeriolysin O (LLO) is necessary for toxicity and bacterial growth. Production of LLO by the non-pathogenic species Lactococcus lactis is sufficient to induce mortality in the insect model. We employed real-time bioluminescence imaging to examine the dynamics of listerial growth and virulence gene expression in the G. mellonella model. Analysis of lux promoter fusions demonstrated

Biochemical analyses can point to toxicant presence before its effects can be detected at higher organizational levels. We investigated responses of larval mass and alkaline phosphatase (ALP) to different cadmium treatments in 4th instar gypsy moth larvae from 20 full-sib families. Changes in trait values and trait plasticities as well as their variation were monitored after acute and chronic exposure or recovery from two cadmium concentrations (Cd(1) = 10 mu g and Cd(2) = 30 mu g Cd/g dry food). Larval mass only decreased, without returning to the control level at recovery stage following chronic cadmium challenge. Acute stress did not change trait value but increased genetic variance of larval mass. Significant ALP activity changes, sensitivity of isozyme patterns (Mr of 60, 64, and 85 kDa) and increased variation in ALP plasticity during acute exposure to cadmium point to its possible aplication as an exposure biomarker.

A new insect member of the signal transducer and activator of transcription (STAT) family of transcription factors, Hyphantria cunea STAT (HcSTAT), was cloned from the lepidopteran H. cunea. The domain involved in DNA interaction and the Src homology 2 (SH2) domain were well conserved. During all developmental stages, the gene was expressed at a low level in the haemocytes, fat body cells, midgut, epidermis and Malpighian tubules. The haemocytes and Malpighian tubules showed transcriptional activation of HcSTAT upon Gram-negative and Gram-positive bacterial challenges. These challenges increased the induction and nuclear translocation of the HcSTAT protein that recognizes a STAT target site in H. cunea haemocytes. In vivo treatment with sodium orthovanadate translocated HcSTAT to the haemocyte nucleus. This study shows the involvement of the haemocyte Janus kinase/STAT pathway after microbial infection in lepidopteran insects ...

Larval populations of diamondback moth have been approaching threshold levels in some canola fields in the southwest. Generally canola can compensate well for diamondback moth feeding to buds and flowers, provided soil moisture is adequate. Some of the areas where the diamondback moth populations were high were also areas that had been drier. So in addition to the diamondback moth populations, consider the growing conditions and the plants abilities to compensate for bud and flower feeding. Heavy rainfall can be a mortality factor of eggs and early instars of diamondback moth. So in addition to providing moisture to help the plants compensate for feeding, with heavy rains larvae are very susceptible to drowning, and may be washed or wriggle to leaf axils or the ground where they drown in accumulated water. If it is decided that an insecticide application is needed, and there is any flowering on the crop, you want to make sure you minimize risk to pollinators, which can help increase the yield of ...

Complete genome sequences of two Australian isolates of single nucleopolyhedrovirus (HaSNPV) and nine strains isolated by plaque selection in tissue culture identified multiple polymorphisms in tissue culture-derived strains compared to the consensus sequence of the parent isolate. other HaSNPV isolates. The Australian isolates and derived strains had greater sequence similarity to New World SNPV isolates from than to Old 15687-27-1 IC50 World isolates from are of importance due to their worldwide distribution and widespread use as biopesticides against these significant polyphagous pests [3]. Group II singly-enveloped nucleopolyhedroviruses from species of the genus (Lepidoptera: Noctuidae) were originally classified into two species; Old World single nucleopolyhedrovirus (HaSNPV), isolated from (Hbner) and New World single nucleopolyhedrovirus (HzSNPV) isolated from (Boddie) [3,4,5,6,7,8,9,10,11,12,13]. This has been recently revised to classify both types as a single species, HaSNPV, with ...

Transgenic maize and cotton expressing Bacillus thuringiensis (Bt) toxins were first commercialized in 1996. By 2009, Bt crops were planted on ca. 47.6 Mha in 22 countries worldwide, with the USA and Canada accounting for 54% of this area. Resistance (virulence) development in target insect pests is a major threat to the sustainable use of Bt crops. Four major target pests of Bt crops in the USA and Canada - European corn borer, Ostrinia nubilalis (Hübner), southwestern corn borer, Diatraea grandiosella Dyar (both Lepidoptera: Crambidae), tobacco budworm, Heliothis virescens Fabricius (Lepidoptera: Noctuidae), and pink bollworm, Pectinophora gossypiella (Saunders) (Lepidoptera: Gelechiidae) - remain susceptible to Bt toxins after 15 years of intensive use of Bt maize and Bt cotton. The success in sustaining susceptibility in these major pests is associated with successful implementation of the high-dose/refuge insecticide resistance management (IRM) strategy: (i) Bt crop cultivars express a ...

European corn borer: Moths were caught in pheromone traps all around the state this week, and larval feeding damage is showing up on early corn. In whorl stage corn the control threshold is 30% of plants showing feeding injury. Once the plants reach the pre-tassel stage the threshold is lowered to 15%, because larvae at this stage are more likely to damage the ears. Early fields in North Berwick, Poland Spring and Sabattus were over threshold for either whorl or pre-tassel corn, so sprays were recommended. Once corn reaches the silk stage, sprays may be based on the number of corn borer moths caught in pheromone traps rather than feeding injury. If more than 5 moths are caught in pheromone traps in a week near silking corn, a spray is recommended to prevent moths from laying eggs on the flag leaves of the ears, which could lead to larvae infesting the ears while leaving no visible signs of feeding on the leaves. One early silking field in Dayton was over the 5-moth threshold this week.. Corn ...

What do clothes moths eat?. The moths do not eat clothes; the larva stage is when they are the most destructive. Clothes moth larvae will consume anything made from animal-based fibers, such as fur, wool, cashmere, feathers, alpaca, and even dead animals. These are the very same fibers that are often found in rugs, chairs, curtains, blankets, socks, gloves, sweaters, scarves, coats, taxidermy collections, hairballs from a pet, lint, tapestry, vintage clothing, teddy bears, and knitting yarn.. From the fibers mentioned above, webbing and casemaking larvae create feeding tubes on which they feed. Casemaking larvae will carry the tube with them, feeding from either end. Webbing larvae will spin silken tunnels over the fibers they are feeding on, forming a place where they can safely hide. These silken tubes and tunnels take on the color of the materials being consumed.. New or freshly laundered fibers are not very appetizing to clothes moths; they prefer a slightly seasoned meal-bodily fluids and ...

LSU AgCenter Horticulturist. The buck moth caterpillar can be found feeding on trees in spring - particularly oaks such as the live oak and water oak. Populations vary around the state from year to year, but this is an excellent time to start checking your oak trees for signs of infestation. Checking is especially important if you had a problem with them last year.. These large, black-spined caterpillars that occur in the spring actually began their life cycle in late November through December. At that time the adult buck moths, which have black and white wings and rusty red abdomens, emerged from underground, where they spent the summer in the pupal or resting stage. Once they emerged the male and female moths mated, and the females laid clusters of 80 to 100 eggs on small twigs in the canopy of oak trees.. The eggs begin to hatch generally from mid- to late February to early March. As the feeding caterpillars grow and develop, they shed their skin several times. When shedding occurs, some of ...

What is the difference between butterflies, moths, and skippers?. Butterflies: drink and rest with their wings up, but sun themselves with their wings outstretched. They have smooth antennae with a knob at the end. Their body hardens into a chrysalis for metamorphosis. They are active in the daytime. Some can be quite colourful.. Moths: rest with their wings outstretched along their back, or tented. Have feathery antennae. They spin a cocoon with silk for metamorphosis, and some species are active during the night, while others are active during the day. They are usually muted colours. Their bodies are usually fuzzier and plumper than that of butterflies.. Skippers: are often considered a mix between butterflies and moths. They rest usually with their wings angled upwards, sometimes outstretched, although parted, and rarely completely folded upwards. Like butterflies, they are active during the day, and have smooth antennae with a club end, although the club is often hooked. Like moths they are ...

The present study was aimed to evaluate the growth and antioxidant defense protection of the silkworm (Antheraea mylitta) larvae (IInd instar), when fed on Terminalia arjuna leaves supplemented with a trace element, Zinc, for 10 days.

Baculovirus IAP (inhibitor-of-apoptosis) genes originated by capture of host genes. Unmodified short antisense DNA oligonucleotides (oligoDNAs) from baculovirus IAP genes can down-regulate specific gene expression profiles in both baculovirus-free and baculovirus-infected insects. In this study, gypsy moth (Lymantria dispar) larvae infected with multiple nucleopolyhedrovirus (LdMNPV), and LdMNPV-free larvae, were treated with oligoDNA antisense to the RING (really interesting new gene) domain of the LdMNPV IAP-3 gene. The results with respect to insect mortality, biomass accumulation, histological studies, RT-PCR, and analysis of DNA apoptotic fragmentation suggest that oligoRING induced increased apoptotic processes in both LdMNPV-free and LdMNPV-infected insect cells, but were more pronounced in the latter. These data open up possibilities for promising new routes of insect pest control using antisense phosphodiester DNA oligonucleotides.

In the spring of 1999, a bacterial pest control product called Foray 48B (manufactured by Abbott Laboratories), was applied by aircraft (aerial spray) to selected areas of Southern Vancouver Island to combat an infestation of the North American Gypsy Moth. Foray 48B contains the bacteria Bacillus thuringiensis subspecies kurstaki HD1 (Btk-HD1) as the active ingredient. Foray 48B also contains water and other ingredients.

This paper reports the results of studies on a Nuclear Polyhedrosis Virus(SiNPV) isolated from the mulberry caterpillar [Sacopolia illoba (Butler)]in Harbin. In most cases there were 4--5 nucleooapsids enveloped within eachvirus bundle of SiNPV. The polyhedra of SiNPV were 2. 06±0. 27μm in diameter,and nucleocapsids were measured about (0.36±0.01)×(0.058±0. 004)μm. SiNPVwas also infectious to the neonate larvae of several other noctuids includingDiscestra stigmosa, Mamestra brassicae, Scotia segetum, S. ips...

TY - JOUR. T1 - Histamine-immunoreactive neurons in the midbrain and suboesophageal ganglion of the sphinx moth Manduca sexta. AU - Homberg, U.. AU - Hildebrand, John G. PY - 1991. Y1 - 1991. N2 - This paper describes the distribution of histamine-like immunoreactivity in the midbrain and suboesophageal ganglion of the sphinx moth Manduca sexta. Intense immunocytochemical staining was detected in ten bilateral pairs of neurons in the median protocerebrum and in one pair of neurons in the suboesophageal ganglion. Whereas most areas of the brain and suboesophageal ganglion are innervated by one or more of these neurons, typically no immunoreactive fibers were found in the mushroom bodies, the protocerebral bridge, and the lateral horn of the protocerebrum. The 11 histamine-immunoreactive neurons were reconstructed from serial sections. Ten neurons have bilateral arborizations, often with axonal projections in symmetric areas of both hemispheres. One neuron, whose soma resides in the lateral ...
