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 ...
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 ...
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?

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.. ...

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 ...
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 ...

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 ...

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 ...

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.. ...

When is a ctenuchid moth not a ctenuchid moth? When its a White-tipped Black Moth (Melanchroia chephise) in the family Geometridae!. I may be a beetle guy, but I also consider myself a competent general entomologist. What is a competent general entomologist? Someone who can identify any insect to order at first glance and a majority of them to family - regardless of ones own taxa of expertise. Thus, when I encountered this mating pair of moths on the outside wall of my sister-in-laws condominium in Seminole, Florida, I "recognized" them as something in what I learned as the family Ctenuchidae (later subsumed within the Arctiidae, first as a subfamily and now as several disparate tribes). They had all the hallmarks of ctenuchids-black and red coloration, narrowish wings with light colored patches, and about the size of the wasps that they presumably mimic. Upon my return to St. Louis, I sat down to identify the moths-confident that their distinctive appearance would lead to the quick ID that ...

Cultivars of Bt corn (which express proteins from Bacillus thuringiensis) are available which are resistant to feeding by European corn borer, and for some cultivars feeding by certain other caterpillars. If planting cultivars of Bt corn, a refuge of non-Bt cultivars is required to be planted to reduce the odds of European corn borer developing resistance to Bt corn. There are 2 types of refuge. Some cultivars of Bt corn will be purchased containing an integrated refuge (sometimes referred to as refuge-in-a-bag), where seeds of a refuge cultivar have been pre-mixed with seeds of the Bt cultivar in the bag. This integrated refuge typically comprises 5% or 10% of the seeds in the bag. Other Bt cultivars will not have an integrated refuge blended in, in which case blocks or strips of a cultivar of corn susceptible to European corn borer needs to be planted within or adjacent to the Bt cultivar. This is called a structured refuge. Planting a non-Bt refuge is a requirement set by the Canadian Food ...
The Noctuids are members of the Superfamily Noctuoidea. Worldwide in distribution, this family is the largest in the Lepidoptera and has approximately 20,000 species. About 2,900 of these are found in North America, and there is wide variation in appearance and behavior. Most moths are gray to brown in color and have line or spots on their wings. Some species are brightly colored. They are small to large in size, and most species are medium-sized with wingspans 2 - 4.5 cm. When at rest, adults of most species hold their wings above their bodies like a roof. Noctuids are typically nocturnal, though some species are diurnal. Most larvae feed on plant foliage, dead leaves, lichens, and fungi; many are serious forest pests. Some species are leaf miners, others are stem- or leaf-borers, and still others feed at night on plant shoots. Noctuid moths pupate in cells in soil, in plant cavities, or in silk cocoons.. ...
use, do not have an offensive odor, are safe to use around residences and hopefully could be classified as "organic." Most home garden sprayers also dont cover the leaf and fruit surfaces very well, because of low pressure and the small volume of water used. Individual backyard apple, pear, and walnut trees or small-scale orchards with a few trees on a couple of acres have not been effectively protected from codling moth damage with the pheromone dispensers and mating disruption technique. This is primarily due to the inability to saturate enough of an area around the orchard to prevent the males from finding the females, mating to occur, and the females returning to the trees to lay eggs (Brown 1996). Conventional growers of commercial-sized orchards use pheromone baited monitoring traps to time insecticide sprays that kill the adults and young larva. Pheromone technology has been an effective method for monitoring male codling moth numbers for over twenty-five years. The synthetic female ...
The Greater wax moth Galleria mellonella belongs to the family of Pyralidae which cause great damage to the honey bee yield worldwide, a major insect model. The honey bee cultivation places are most habitat of this insect. Most the organisms of insects rely on their olfactory system to detect and analyse the sensible nature in the environment and it is mostly useful in the concept of behavioural emotions includes mating, host defence and other sensory related molecular functions. This organism is the only member of the genus Galleria and also it is found in most the places in the world. The larvae of Galleria mellonella is used as commercial product as proving the food for predatory insects. The pathogenicity and toxicology testing were making the researchers easy by replacing the use of small mammals for in-vivo and in-vitro studies. The neurological mechanism of this insect is still unclear.. The ecdysone induced protein is unique protein with various functions, types, diversity in different ...
The yolk of insect eggs consists largely of proteins derived pinocytotically from the maternal blood (Telfer, 1965). Vitellogenic oocytes can also sequester the acidic colloid trypan blue: when injected into the blood, the dye, like the blood proteins, is deposited in yolk spheres in the cortex of the oocyte. This behavior of trypan blue was first described in the scorpian fly by Ramamurty (1964), and has since been confirmed in a cricket (Sander & Vollmar, 1967) and in the cecropia moth (Telfer & Anderson, 1968).. Ovarian follicles of the cecropia moth have also been exposed to trypan blue in vitro; under these conditions the dye is not only incorporated into cortical yolk spheres but is in addition bound at the oocyte surface and in the intercellular spaces which serve as passageways for blood proteins across the follicular epithelium.. ...

Herein, we found a novel single-strand RNA virus by RNA-Seq and Polymerase Chain Reaction (PCR) method in H. armigera named Helicoverpa armigera iflavirus (HaIV), which possessed a genome with 10,017 nucleotides in length and contained a single large open reading frame (ORF) encoding a putative polyprotein of 3021 amino acids with a predicted molecular mass of 344.16 kDa and a theoretical isoelectric point (pI) of 6.45. The deduced amino acid sequence showed highest similarity (61.0%) with the protein of Lymantria dispar Iflavirus 1. Phylogenetic analysis with putative RdRp amino acid sequences indicated that the virus clustered ...
1. Noctuid moths of several species were mounted at the tip of a tower of fine tubing in acoustic free space. Recordings were made of the intensity of a brief pulse of ultrasound necessary to produce a constant tympanic nerve response for any angle of sound presentation relative to the moths body axis. Such plots of intensity versus angle were made with the wings held in several postures approximating those assumed in normal flight.. 2. The data indicate that sound intensity reaching the tympanic organ can vary by as much as 40 db. depending upon: (a) the position of a sound source relative to the moths body axis, and (b) the position of its wings.. 3. With wings above the horizontal plane each ear reports sounds c. 20-40 db. louder on the ipsilateral side than on the contralateral side. With wings below the horizontal, the lateral asymmetries are replaced by a dorsoventral asymmetry in which each ear reports sounds coming from below the body c. 10-25 db. louder than sounds coming from ...
The vast majority of lepidopterans, about 90%, are moths. Some moths, particularly their caterpillars, are major agricultural and forestry pests in many parts of the world. However, some other members of moths, such as the silkworm Bombyx mori, are famous for their economic value. Fire et al. in 1998 initially found that exogenous double-stranded RNA (dsRNA) can silence the homolog endogenous mRNA in organisms, which is called RNA interference (RNAi). Soon after, the RNAi technique proved to be very promising not only in gene function determination but also in pest control. However, later studies demonstrate that performing RNAi in moths is not as straightforward as shown in other insect taxa. Nevertheless, since 2007, especially after 2010, an increasing number of reports have been published that describe successful RNAi experiments in different moth species either on gene function analysis or on pest management exploration. So far, more than 100 peer-reviewed papers have reported successful RNAi

Vedalia 12:33-60. Interpretive Summary: Codling moth is the most serious insect pest of apple in the Pacific Northwest of the United States. The traditional method for controlling this pest is through the routine application of broad spectrum insecticides. Options for codling moth control for organic growers has been limited to oils, trapping, mating disruption, manual removal of infested fruit and the like. A number of natural enemies including insect-specific pathogens, parasitic wasps and predators, have been tested or developed as biological control agents that can be used as alternatives to chemical insecticides for the control of codling moth. Researchers at the USDA-ARS, Yakima Agricultural Research Laboratory have conducting studies to develop and evaluate a variety of biological control ...

The alkane penetrates deep into the tracheoles and absorbs onto nerve membranes, apparently causing direct nervous disruption. In electrophysiological experiments, Citrus Postharvest Dip in the ganglia induced a rapid onset of multiple nerve firing in peripheral nerves of LBAM larvae. Repetitive firing after exposure to the C15 alkane or ...
State, federal and local agricultural officials are set to begin efforts to eradicate the light brown apple moth from Cayucos. Starting next Monday, technicians will deploy twist ties infused with a pheromone. Typically, a pheromone is released by the female moth to attract a mate. But the pheromone used in this program will disrupt the moths breeding patterns. Eventually, the moth population will decline and collapse, farm officials say.
Within one hundred years (1850 to 1950); the dotted whitish form of the peppered moth (Biston betularia) was almost entirely replaced by the melanic (black) form. The melanic form appeared to be best suited for survival against the soot that had collected on forest tree trunks from pollution because the moths could camouflage with their resting area on the tree. The dotted whitish form of the peppered moth was no longer predominant in this environment because they were easily detected and predated on. How does this happen? Many animals have anti-predator adaptations. Adaptations are defined as "a heritable trait that either spread because of natural selection and has been maintained by selection to the present or is currently spreading relative to alternative traits because of natural selection (Alcock, 2001)." Anti-predator adaptations suggest that a heritable trait, which enables the organism to hide from predators by seeking cover against a background, has spread by natural selection because ...
The Peppered Moth (Biston betularia) is a common moth that is used as a common example of observable natural selection. Before soot blackened its native birch trees, the white varielty of this moth was more common - afterwards, the darker variety was prevalent
Introduction. Insects are very diverse and play fundamental roles in ecosystems. Adult lepidopterans (butterflies and moths) are important pollinators of wild plants and also many food crops (Kondo, 2012). Their larvae, in contrast, have a great negative impact on plants, eating their leaves, flowers, fruits, seeds, branches and even roots (Weisse and Siemann, 2008). Out of their natural habitat lepidopterans can become important pests. The owlet moths, Anicla infecta (Ochsenheimer, 1816), Elaphria agrotina (Guenée, 1852) and Spodoptera frugiperda (J.E. Smith, 1797) are good examples of this. They occur throughout the American continent and recently, S. frugiperda has also been detected in the African continent (Goergen et al., 2016), Europe (CABI, 2017) and India (Shylesha et al., 2018). Their caterpillars are polyphagous, with a strong preference for grasses (Teston et al., 2001; Lafontaine, 2004; Casmuz et al., 2010; Specht et al., 2014; Montezano et al., 2018). The caterpillar of A. infecta ...
The caterpillars of oak processionary moths have thousands of tiny hairs that can cause itchy rashes, eye problems and sore throats - and, very occasionally, breathing difficulties. If you see them crawling up and down trees in nose-to-tail processions or spot one of their white silken nests, report it to the Forestry Commission or your local council. Prevent oak processionary moth problems: Dont touch or approach the caterpillars or nests. Dont try to remove the nests yourself - call a pest control expert. If a caterpillar is on your skin: Use tweezers or a pen to remove it. Try not to disturb it (for example, by brushing it with your hands) as it will then release more hairs. If you think youve been exposed: Rinse with running water, allow to air dry, and then use sticky tape to strip off any leftover hairs. Use calamine, ice packs or a remedy from the pharmacy containing 3.5% ammonia to relieve the itch. Remove all contaminated clothes and wash at as high a temperature as the fabric ...
