Endosymbiont phylogenesis in the dryophthoridae weevils: evidence for bacterial replacement. (1/124)Intracellular symbiosis is widespread in the insect world where it plays an important role in evolution and adaptation. The weevil family Dryophthoridae (Curculionoidea) is of particular interest in intracellular symbiosis evolution with regard to the great economical and ecological features of these invasive insects, and the potential for comparative studies across a wide range of host plants and environments. Here, we have analyzed the intracellular symbiotic bacteria of 19 Dryophthoridae species collected worldwide, representing a wide range of plant species and tissues. All except one (Sitophilus linearis) harbor symbiotic bacteria within specialized cells (the bacteriocytes) assembled as an organ, the bacteriome. Phylogenetic analysis of the 16S rDNA gene sequence of the Dryophthoridae endosymbionts revealed three endosymbiotic clades belonging to gamma3-Proteobacteria and characterized by different GC contents and evolutionary rate. The genus name Candidatus Nardonella was proposed for the ancestral clade infesting Dryophthoridae 100 MYA and represented by five of nine bacterial genera studied. For this clade showing low GC content (40.5% GC) and high evolutionary rate (0.128 substitutions/site per 100 Myr), a single infection and subsequent cospeciation of the host and the endosymbionts was observed. In the two other insect lineage endosymbionts, with relatively high GC content (53.4% and 53.8% GC), competition with ancestral pathogenic bacteria might have occurred, leading to endosymbiont replacement in present-day last insects.

Molecular cloning of a cysteine proteinase cDNA from the cotton boll weevil Anthonomus grandis (Coleoptera: Curculionidae). (2/124)The cotton boll weevil (Anthonomus grandis) causes severe cotton crop losses in North and South America. This report describes the presence of cysteine proteinase activity in the cotton boll weevil. Cysteine proteinase inhibitors from different sources were assayed against total A. grandis proteinases but, unexpectedly, no inhibitor tested was particularly effective. In order to screen for active inhibitors against the boll weevil, a cysteine proteinase cDNA (Agcys1) was isolated from A. grandis larvae using degenerate primers and rapid amplification of cDNA ends (RACE) techniques. Sequence analysis showed significant homologies with other insect cysteine proteinases. Northern blot analysis indicated that the mRNA encoding the proteinase was transcribed mainly in the gut of larvae. No mRNA was detected in neonatal larvae, pupae, or in the gut of the adult insect, suggesting that Agcys1 is an important cysteine proteinase for larvae digestion. The isolated gene will facilitate the search for highly active inhibitors towards boll weevil larvae that may provide a new opportunity to control this important insect pest. (+info)
Five types of olfactory receptor neurons in the strawberry blossom weevil Anthonomus rubi: selective responses to inducible host-plant volatiles. (3/124)Plants release hundreds of volatiles that are important in the interaction with herbivorous animals, but which odorants are detected by which species? In this study, single receptor neurons on the antenna of the oligophagous strawberry blossom weevil Anthonomus rubi were screened for sensitivity to naturally produced plant compounds by the use of gas chromatography linked to electrophysiological recordings from single cells. The narrow tuning of the neurons was demonstrated by responses solely to a few structurally related sesquiterpenes, aromatics or monoterpene hydrocarbons out of hundreds of plant constituents tested. We present five olfactory receptor neuron types, identified according to one primary odorant i.e. the compound to which the neurons are most sensitive. These odorants, (-)-germacrene D, (-)-beta-caryophyllene, methyl salicylate, E-beta-ocimene and (3E)-4,8-dimethyl-1,3,7-nonatriene, present in the intact strawberry plant, are induced in higher amounts by weevil feeding. This suggests that these compounds can provide information about the presence of conspecifics. We used protocols especially designed to allow comparison with previously investigated species. Striking similarities, but also differences, are demonstrated between receptor neuron specificity in the strawberry weevil and moths. (+info)
A microfluorometric method for quantifying RNA and DNA in terrestrial insects. (4/124)Evidence is accumulating for a mechanistic linkage between body phosphorus content and growth and reproduction of individual organisms, due in part to variation in allocation of resources to ribosomal RNA. Testing this connection requires reliable methods of quantifying the nucleic acid content of individual organisms. Although methods for quantifying nucleic acids are available for a wide array of organisms, adaptation of such methods for study of insects has been neglected. Sensitive stains and high throughput fluorometric measurements are now available that substantially improve past methodologies. Here we present methods for the extraction and quantification of insect RNA and DNA based on the use of N-lauroylsarcosine and sonication for extraction, the nucleases RNase and DNase, and the use of microplate fluorescent assays to quantify nucleic acids as percent of body weight in insects. We illustrate the method using Drosophila and curculionid weevils. (+info)
Iridovirus in the root weevil Diaprepes abbreviatus. (5/124)Invertebrate iridescent virus 6 (IIV6) was evaluated for mode of transmission and ability to cause infection in the root weevil, Diaprepes abbreviatus (L.). This is the first evidence of IIV6 infection in D. abbreviatus, which caused both patent and sub-lethal covert infections in both larvae and adults. Adults and larvae were successfully infected with IIV6 by puncture, injection and per os. Transmission of IIV6 was demonstrated between infected and healthy individuals regardless of gender. Virus was detected in egg masses produced by virus-infected females suggesting IIV6 is transmitted transovarially. Virus particles were observed in the cytoplasm of weevil cells, and were shown to infect fat bodies, muscle, and nerve tissues, as visualized using transmission electron microscopy. Patent infections resulted in death of individuals within 3 to 4 days post infection. Individuals with covert infections tested positive for virus infection on day 7 by polymerase chain reaction analysis. Sequencing of PCR amplicons confirmed virus infection. Discovery of new pathogens against root weevils may provide new management tools for development of control strategies based on induced epizootics. This is the first report of a virus infecting D. abbreviatus. (+info)
Polygalacturonase from Sitophilus oryzae: possible horizontal transfer of a pectinase gene from fungi to weevils. (6/124)Endo-polygalacturonase, one of the group of enzymes known collectively as pectinases, is widely distributed in bacteria, plants and fungi. The enzyme has also been found in several weevil species and a few other insects, such as aphids, but not in Drosophila melanogaster, Anopheles gambiae, or Caenorhabditis elegans or, as far as is known, in any more primitive animal species. What, then, is the genetic origin of the polygalacturonases in weevils? Since some weevil species harbor symbiotic microorganisms, it has been suggested, reasonably, that the symbionts' genomes of both aphids and weevils, rather than the insects' genomes, could encode polygalacturonase. We report here the cloning of a cDNA that encodes endo-polygalacturonase in the rice weevil, Sitophilus oryzae (L.), and investigations based on the cloned cDNA. Our results, which include analysis of genes in antibiotic-treated rice weevils, indicate that the enzyme is, in fact, encoded by the insect genome. Given the apparent absence of the gene in much of the rest of the animal kingdom, it is therefore likely that the rice weevil polygalacturonase gene was incorporated into the weevil's genome by horizontal transfer, possibly from a fungus.

Iridovirus infection of cell cultures from the Diaprepes root weevil, Diaprepes abbreviatus. (7/124)We here report the development and viral infection of a Diaprepes root weevil cell culture. Embryonic tissues of the root weevil were used to establish cell cultures for use in screening viral pathogens as potential biological control agents. Tissues were seeded into a prepared solution of insect medium and kept at a temperature of 24 degrees C. The cell culture had primarily fibroblast-like morphology with some epithelial monolayers. Root weevil cells were successfully infected in vitro with a known insect virus, Invertebrate Iridescent Virus 6. Potential uses of insect cell cultures and insect viruses are discussed. (+info)
Protein-enriched pea flour extract protects stored milled rice against the rice weevil, Sitophilus oryzae. (8/124)Studies were conducted to evaluate the effect of a protein-enriched pea (Pisum sativum var. Bonneville) flour extract against the rice weevil, Sitophilus oryzae in its repellency, toxicity, effect on fecundity, stability and sensory properties. Milled rice admixed with pea flour extract at 1% concentration significantly repelled S. oryzae. Mortality of S. oryzae was found to increase and fecundity was markedly suppressed, in rice treated with 1% pea flour extract. The toxicity and reproductive effects of the pea protein-enriched rice were found to be stable for a period of 5 months. The sensory characteristics of stored rice when eaten were not affected by the treatment with pea flour extract. This study indicates that the protein-enriched flour extract obtained from the Bonneville pea may be feasible to protect stored milled rice from insect attack. (+info)
The influence of rice plant age on susceptibility to the rice water weevil, Lissorhoptrus oryzophilus - Stout - 2012 - Journal...
Plant age- and plant stage-related changes in the resistance of rice, Oryza sativa, to its most important insect pest in the US, the rice water weevil (Lissorhoptrus oryzophilus), were investigated in a series of field and greenhouse choice and no-choice studies. Rice plants were susceptible to infestation by rice water weevils over a broad range of plant ontogenetic stages, from at least the early vegetative stage to well into the reproductive stage. There was, however, a clear preference expressed by rice water weevils in both choice and no-choice experiments for plants in (or nearly in) the tillering stage of development, with pre-tillering and reproductive stage plants less preferred. The relationship between rice plant age and susceptibility to weevils is thus nonlinear. This study constitutes one of the most thorough studies to date of the relationship in a grass species between plant age and susceptibility to herbivores. The results provide a biological explanation for observed patterns ...
JIPM Offers Rice Growers a New Resource Against the Rice Water Weevil
The rice water weevil, Lissorhoptrus oryzophilus, is the most harmful insect pest of rice in the United States, causing yield losses of up to 25 percent. Adults inflict damage by consuming leaf tissue, and the larvae feed on the roots of rice plants. A native of the southeastern U.S., the rice water weevil invaded Japan in 1976, Korea in 1980, China in 1988, and Italy in 2004. Luckily, rice growers now have a new resource for controlling it. An open-access article appearing in the Journal of Integrated Pest Management discusses the rice water weevils life history and invasion biology, as well as management strategies and future directions of research.. Authors Mohammad-Amir Aghaee and Larry D. Godfrey, both from the University of California, Davis, tell the story of the weevil since it was first identified as a pest in 1881 by C. V. Riley and L. O. Howard. They then discuss reasons why it has been able to spread so rapidly - up to 36 kilometers per year in some cases - which is partly because ...
Red Palm weevils found in Laguna Beach, CA - Page 9 - DISCUSSING PALM TREES WORLDWIDE - PalmTalk
High concern after the discovery of palm infested by the red palm weevil in California. Michel Ferry. INRA. Email: [email protected] In august of this year, trimmers found in Laguna Beach that a drying Phoenix canariensis that they planned to remove was infested by a weevil. Early in October, it was officially confirmed that this weevil was Rhynchophorus ferrugineus. In the same area, another infested Phoenix canariensis has been detected in november. These two palms were already established for a long time. Consequently, they have been infested by flying weevils coming from other infested ones. Furthermore, they have been detected at a very forward stage of infestation and, so have had enough time to become intense dispersal focus of the pest. The pest is certainly present in this area for at least one year. All the palms around the virulent spot of Laguna Beach have to be considered as infested.. This situation is very worrying because the red palm weevil is killer of many palm species. ...
Comparative cytogenetics and derived phylogenic relationship among Sitophilus grain weevils (Coleoptera, Curculionidae,...
Cytogenetic characteristics and genome size are powerful tools for species characterization and identification of cryptic species, providing critical insights into phylogenetic and evolutionary relationships. Sitophilus Linnaeus, 1758 grain weevils can benefit from such tools as key pest species of stored products and also as sources of archeological information on human history and past urban environments. Moreover, the phylogenetic relationship among these weevil species remains controversial and is largely based on single DNA fragment analyses. Therefore, cytogenetic analyses and genome size determinations were performed for four Sitophilus grain weevil species, namely the granary weevil Sitophilus granarius (Linnaeus, 1758), the tamarind weevil S. linearis (Herbst, 1797), the rice weevil S. oryzae (Linnaeus, 1763), and the maize weevil S. zeamais Motschulsky, 1855. Both maize and rice weevils exhibited the same chromosome number (2n=22; 10 A + Xyp). In contrast, the granary and tamarind ...
Screening of promising maize genotypes against maize weevil (Sitophilus zeamais Motschulky) in storage condition |...
The maize weevil (Sitophilus zeamais Motschulsky) is a serious pest of economic importance in stored grains. It causes major damage to stored maize grain thereby reducing its weight, quality and germination. An experiment was conducted in randomized complete block design (RCBD) with 3 replications to screen 32 maize genotypes against maize weevil in no-choice and free-choice conditions at Entomology Division, Khumaltar, Lalitpur (Room temperature: Maximum 24-32°C and Minimum 18-27°C). The findings showed that the maize genotypes had different response to maize weevil damage ranging from susceptible to tolerance. The genotypes Manakamana-3, Lumle White POP Corn and Ganesh-2 showed their tolerance to S. zeamais as evidenced by lower number of weevil emerged/attracted, lower amount of grain debris release and lower proportion of bored grains, while the genotype ZM-627 was the most susceptible to weevil damage in both tests. The other remaining genotypes were intermediate types. This information ...

The Making of a South American Palm Weevil Mini-Documentary for Deep Look with KQED | Center for Invasive Species Research
The South American palm weevil, Rhynchophorus palmarum (Coleoptera: Curculionidae), is well established in parts of San Diego County in California and is responsible for killing numerous Canary Islands date palms. The spectacular damage this invasive pest causes and the large showy adult weevils and alien-looking larvae and pupae, captured the imagination of Elliott Kennerson and Joshua Cassidy, digital media producers for the science show Deep Look with KQED Public Television and Radio in San Francisco. After a few phone calls and ensuing discussions, Elliott made the pitch to KQED to develop a story on the palm weevil and the project was given approval for development.. A plan was made to drop a weevil infested Canary Island date palm tree in a residential area in San Diego County and from this palm weevil life stages would be collected and filmed. The first challenge was finding an infested palm, which we did, and the bigger challenge was to bring the palm down and then cut it up so we could ...
SOMEONE IN AL AIN: Red palm weevil
This is a Rhynchophorus ferrugineus, the red palm weevil is a species of beetle. It is relatively large, between two and five centimeters long, and a rusty red colour. Its larvae excavate holes up to a metre long in the trunk of palm trees, and can kill the host plant. As a result, the beetle is a pest of palm plantations of palms such as the coconut palm, date palm or oil palm. Originally from tropical Asia, the red palm weevil has spread to Africa and Europe, reaching the Mediterranean in the 1980s, and was first recorded in Spain in 1994 and in France in 2006 ...

A Quick Guide to- the Weevil - Wildlife Articles
Many of us in Britain will have heard the name Weevil uttered at some time or another. For me, I first heard it as a child when I opened up a bag of flour to find it crawling with Weevil larvae. Recently, I came across a Weevil infestation in a large quantity of bird seed and I realised that although I knew what the insect was, I didnt know much else about it. So I set off to learn a few facts on this common insect. There are over 60,000 species of weevil worldwide. The Rice, Granary and Maize Weevils are pests of grain throughout the world and can cause extensive damage to stored grain. The weevil I came across was the Granary Weevil, Sitophilus granarius, and this is the insect we will focus on in this article.. The adult Granary Weevil is dark brown to black in colour, about 3-4mm in length and cannot fly. The Weevil has a distinctive look due to the large snout extending from the head. The larvae are white, legless grubs that eventually change to white naked pupa, before emerging from the ...
Genetic conservation of Phosphine Resistance in the Rice Weevil Sitophilus oryzae (L.)
High levels of resistance to phosphine in the rice weevil Sitophilus oryzae have been detected in Asian countries including China and Vietnam, however there is limited knowledge of the genetic mechanism of resistance in these strains. We find that the genetic basis of strong phosphine resistance is conserved between strains of S. oryzae from China, Vietnam and Australia. Each of four strongly resistant strains has an identical amino acid variant in the encoded dihydrolipoamide dehydrogenase (DLD) enzyme that was previously identified as a resistance factor in Rhyzopertha dominica and Tribolium castaneum. The unique amino acid substitution, Asparagine , Threonine (N505T) of all strongly resistant S. oryzae corresponds to the position of an Asparagine , Histidine variant (N506H) that was previously reported in strongly resistant R. dominica. Progeny (F16 and F18) from two independent crosses showed absolute linkage of N505T to the strong resistance phenotype, indicating that if N505T was not ...
Sabinet | Hot-water treatment for the control of the banana weevil, Cosmopolites sordidus Germar (Coleoptera: Curculionidae),...
Paring and hot-water treatment of banana suckers have been recommended to prevent the spread of banana weevil, Cosmopolites sordidus Germar, into new banana plantations. Mortality of banana weevil eggs and larvae were recorded after immersion of infested banana suckers in four hot-water regimes: 43C for 2 hours, 43 C for 3 hours, 54 C for 20 minutes and 60 C for 15 minutes. Paring removed 90 % of banana weevil eggs, while all hot-water treatments resulted in 100 % mortality of eggs. However, only hot-water baths of 43C for 3 h resulted in high mortality (94 %) of weevil larvae. Larval mortality in other treatments ranged from 26-32 %. It is unlikely that Ugandan farmers will implement three-hour hot-water baths for banana weevil control. Also, the hot-water treatment that is most effective for nematode control (54 C for 20 min) provided limited control of banana weevil The data suggest that paring alone may be the most appropriate measure for resource-poor farmers to eliminate banana weevil from
Aggregation Pheromone of Palm Weevil, Dynamis borassi
4-Methyl-5-nonanol (1) is the male-produced aggregation pheromone of the palm weevil, Dynamis borassi (F.) from Colombia. The pheromone was identified by coupled gas chromatographic-electroantennographic detection (GC-EAD) analysis of male- and female-produced volatiles, and comparative GC-mass spectrometry (MS) of weevil-produced 1. In field experiments in Colombia, traps baited with a stereoisomeric mixture of synthetic 1 (3 mg/day) plus sugarcane captured more weevils than traps baited with 1 or sugarcane alone, suggesting that pheromone and plant volatiles are synergistically attractive. Use of a chiral, stereoisomer-separating Cyclodex-B column in GC-EAD and GC-MS analyses revealed that D. borassi males produce, and antennae of males and females respond to (4S,5S)-1. Previously identified palm weevil (Rhynchophorus spp.) aggregation pheromones 5-methyl-4-octanol (cruentol) and 6-methyl-2-hepten-4-ol (rhynchophorol) also elicited antennal responses by D. borassi. In field experiments, D. ...

Cottons Obituaries: The Boll Weevil in Georgia : Boll Weevil Blues - oi
This chapter discusses in detail the boll weevil in Georgia, where the image of the boll weevil as the destroyer of the plantation system has proven stronger and more lasting than in any other state. The state leaders made the appearance of preparing the farmers to fight the weevil as the pest approached and then finally invaded Georgia. Since the earliest days of the boll weevils arrival in the state, Georgias farm experts had been very concerned about a labor exodus, and in Georgia, the outmigration had been heavy. The idea that the boll weevil eliminated their cotton livelihood came closer to the truth there than in any of the other Deep South states. The appearance of the pest did correspond with both a decline in the states cotton production and an exodus of cotton laborers. ...
Root Weevils | Manitoba Agriculture | Province of Manitoba
Adult strawberry root weevils are about 5 to 8 mm long. They are usually black, but some may be light-to dark-brown. They have rows of round punctures on the wing covers. All the adults are females. They cannot fly. Larval root weevils are legless grubs with pinkish-white C-shaped bodies and brown heads. They are about 6 mm long.. Root weevils reproduce asexually and all root weevils are therefore female. These beetles are unable to fly and are active at night. Most root weevils overwinter as larvae near the roots of their host plants. In spring they pupate and adults begin to emerge in early July. Adult weevils are 5-9 mm long and vary in colour from black to light brown to gray in colour, depending upon the species. In late July, the females deposit the eggs near the crown of the host plant. The eggs hatch and the larvae burrow into the soil to feed on the roots for the remainder of the season. Larvae are legless grubs with whitish bodies and brown heads and reach a length of 6 mm. There is ...

white pine weevil
Or have you noticed the top of the tree is brown, drooping or curved? White pine weevil (7-58) - Scout for adults on spruce, pine, Doug fir, occasionally fir - especially in areas where you have had it previously. Biology and life history Adult beetles overwinter in litter on the ground. As temperatures warm in the spring, they climb their hosts to feed and lay eggs in the terminals. The latest cytogenetic and breeding studies indicate that two other North American pine weevil species - the Sitka spruce weevil and the Engelmann spruce weevil-also should be classified as Pissodes strobi.

Strawberry Root Weevil | Occasional Invaders Control | Pest Control by Terminix
Size:. ¼-inch long. Color:. Black to blackish-brown. Behavior:. The strawberry root weevil is one of the more common of structure-invading weevils encountered around homes. Both adults and larvae feed primarily upon strawberry plants but will also attack bramble and evergreens such as pine and yew. In nurseries, they are known to be pests of some evergreen shrubs. Both the strawberry root weevil larvae and adults overwinter within leaf litter and other vegetative debris on the ground and, upon warming weather, larvae begin feeding in the soil on the plant roots. The adults emerge soon after and infest the above-ground parts of the plants. Generally, two generations of strawberry root weevils may occur each year. This weevil cannot fly and disperses by crawling, which often brings them wandering into homes and other buildings. In some cases large numbers of weevils may be discovered crawling on floors, walls and even ceilings.. ...

About Weevils | eHow
There are between 40,000 to 60,000 species of weevils--which are a type of beetle--in the world. Most weevils are smaller than 1 inch long; many are smaller than 1/2 inch. Unfortunately, their small size doesnt prevent them from destroying entire cupboards full of food or a field of grain. One female weevil produces around 400 eggs in her short lifetime. It does not take long for a few weevils to become many weevils. Weevils that commonly infest homes, such as granary weevils and rice weevils, lay their eggs inside kernels of grain, which provides food for the growing larvae. Warm, humid temperatures provide ideal conditions for weevil infestations.. ...
Strawberry Root weevils - Sergios Pest Control
The Strawberry Root Weevil, is one of the many species in the weevil family (Curculionidae). Its name comes from its affinity for strawberry plants, which form a large part of its diet. They are, however, known to feed on other plants as well. It is known to be one of the major pests threatening sub-tropical strawberry farming. The adult strawberry root weevil is about six millimeters long, and is dark brown/black in color.. They are often found in the leaves and foliage of the plants they feed on. The adult weevils elytra are fused together, which means they are unable to fly. The larvae can be up to thirteen millimeters long when fully grown and they are found near the roots of the plants they are infesting. The larvae are white, legless, with a darker colored head and are often C-shaped.. Controlling the strawberry root weevil includes a wide variety of methods such as the use of insecticides, plowing under old crops and crop rotation, cleaning farm equipment before moving to a new field, ...
Integrated Management of the Rice Water Weevil
The seasonal history of this pest in Louisiana begins in early spring, when adult weevils emigrate from their overwintering sites to rice fields. Models based on more than 20 years of flight records and weather data predict initial flights of weevils in early April in southwestern Louisiana. Upon arrival in rice fields, adult weevils feed on leaves of rice plants, leaving lengthwise feeding scars. This type of injury, although evidence of the presence of weevils in a field, usually does not result in economic losses. Serious problems do not begin until the rice fields are flooded and the weevils begin to lay eggs. The newly hatched larvae feed externally on the rice plant roots. Root pruning by larvae can damage root systems extensively, ultimately reducing grain yields. The insect has two to three overlapping generations in southern Louisiana. In August, adults of the final generation fly to overwintering sites, primarily wooded areas, and live in bunch grasses and under leaf litter.. An ...
Red Palm Weevil Infested Palm at Laguna Beach Removed
On Wednesday, November 03, 2010, a team of scientists from CISR, CDFA, UCCE, USDA-APHIS, the Orange and San Diego County Agricultural Commissioners Offices and West Coast Arborists returned to the Red Palm Weevil (RPW) affected site in Laguna Beach California. Inspection of a unhealthy Canary Islands palm the previous week resulted in the discovery of a live adult RPW in the trunk. Discussions concluded that the infected tree should be removed to prevent the continued possible breeding and spread of the RPW from that palm to other areas in the immediate vicinity.. The two main goals of the CDFA-sponsored project were: (1) removal and destruction of the RPW infested palm, and (2) to dissect the palm and determine how deep the infestation had proceeded through the trunk of the infested palm. It was decided that dissection of the palm could provide useful information on the level of RPW infestation in the trunk, if any live stages were still present, and how severe the internal damage was.. The ...

A trial to determine yield losses in East African highland banana (cv. Atwalira) to banana weevil was run between 1994 and 2001 at the International Institute of Tropical Agricultures Sendusu Farm in Namulonge, Uganda. Banana weevil adults were released into weevil-infestation plots, while weevils were excluded from controls by trapping and later application of chlorpyrifos. Weevil migration and reproduction in control plots reduced treatment differences in damage during the first 3 yr. Thereafter, weevil damage was heavy in infested plots and negligible in controls. High levels of weevil attack resulted in reduced bunch weights, plant losses, mat disappearance and fewer harvested bunches, with estimated yield losses averaging 42% over the final 4 yr of the trial. The data confirm the importance of banana weevil as an important production constraint of highland banana and support farmer reports that banana weevil attack contributes to shortened plantation life ...

Wireless sensor network based on UAV for weevils surveillance in Saudí Arabia
The Red Palm Weevil o Rhynchophorus ferrugineus is an invasive spice that had become a catastrophic plague for lots of palm trees in Saudi Arabia, but all around the world too. Nowadays, the surveillance of the plague is done using tramps placed near the palm trees, and one person comes to the tramp and counts manually the number of weevils into the tramp. This project is aimed to improve the actual surveillance method. To realize it we have been created a Wireless Sensor Network and different nodes able to obtain the number of weevils into the tramp and they must transmit this data to a mobile node that collect all the data for processing. These sensor units are placed into the tramps, so they measure the weight of the weevils, and the number of them. The sensors are Strain Gauges and the signal conditioning system. This signal obtained from the gauges is processed into the Arduino board. To this microcontroller we can add one shield in order to conect communication devices, in our case, Xbees. ...
Development of female sex organs during aestivation in the alfalfa weevil, Hypera postica (Gyll.) (Coleoptera, Curculionidae)
Laboratory studies and field observations were conducted to ascertain the development of the female sex organs of the alfalfa weevil during aestivation, to study the role of this aestivation on sexual development, and to investigate the factors responsible for this interaction.. Measurements of female sex organs were made in dissected weevils at monthly intervals to observe each of the developmental stages of sexual maturation. Results of this sexual development as it progressed after adult emergence, were presented by means of tables, graphs, and a series of photographs.. The importance of not confusing old and new weevils was recognized in this work, since their behavioral patters differ in many respects. The nature and physiology of the aestivation of this weevil was discussed and evidence was presented to support the authors suggestion that this aestivation is a true diapause. It was demonstrated in this paper that diapause synchronized the sexual growth of the alfalfa weevil to the ...

Black Vine Weevil | Plant Disease Diagnostics Clinic
The black vine weevil commonly infests containerized perennials in nursery, greenhouse, and poly-house production settings. Black vine weevil adults are nocturnal (i.e., they are active at night), thus monitoring for adults should be conducted at night. The adult weevils feed along the margins of leaves resulting in crescent-shaped notches. Light to moderate notching typically has little effect on plant health. Black vine weevils cannot fly, but they are very active walkers. The primary means of dissemination of this insect to new areas is through potted plants or soil root ball transplants. Black vine weevil larvae (i.e., grubs) are legless and approximately 3∕8 inch in length. If soil conditions become excessively moist or young roots become scarce, larvae will often move to larger roots near the base of the plant.. Life Cycle: Female black vine weevil adults emerge from the soil in late-May to early-June. The adult weevils feed on plant material for approximately 21-42 days before laying ...
