Evolution of pest resistance to pesticides is an urgent global problem with recorded in at least 954 species pests, including 546 arthropods, 218 weeds, and 190 plant pathogens. To facilitate understanding management resistance, we provide definitions 50 key terms related resistance. We confirm the broad, long-standing definition which a genetically based decrease susceptibility pesticide, “field-evolved resistance,” pesticide population caused by exposure field. The impact field-evolved on...
The fall armyworm, Spodoptera frugiperda (J. E. Smith), is one of the main pests corn in many areas American continent. reliance on pesticides to control armyworm has led development insecticide resistance regions. We determined levels insecticides different modes action populations from Puerto Rico and several Mexican states with use patterns. that expressed higher ratios (RR50) were: Sonora (20-fold chlorpyriphos), Oaxaca (19-fold permethrin), Sinaloa (10-fold flubendamide). population...
Abstract The Colorado potato beetle, Leptinotarsa decemlineata (Say), has developed resistance to many insecticides used for its control, recently including imidacloprid, a neonicotinoid compound. Other neonicotinoids are now being deployed control this pest. A key point in the strategies of management is monitoring and cross‐resistance. In summer 2003, imidacloprid‐resistant adult beetles collected from Long Island, New York, USA were bioassayed using topical applications imidacloprid nine...
Abstract The discovery of fall armyworm, a native the Western Hemisphere, in western Africa 2016 was rapidly followed by detections throughout sub-Saharan Africa, India, and most recently southeastern Asia. This moth pest has broad host range that threatens such important crops as corn, rice, millet, sorghum, creating concern for its potential impact on agriculture Eastern Hemisphere. Although genetic data suggest populations sampled India originate from recent common source, it is not known...
The invasive fall armyworm, Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae), was reported for the first time causing severe damage on maize in Karnataka, India, during May 2018. Thereafter, pest has spread to most states of India and then other Asian countries, including Thailand, Sri Lanka, Bangladesh, Myanmar, Vietnam, Laos, China. Being a new invasive, there is no information its susceptibility insecticides. Hence, insecticides having different modes action were evaluated...
Fall armyworm (FAW), Spodoptera frugiperda, a major pest of corn and native to the Americas, recently invaded (sub)tropical regions worldwide. The intensive use insecticides high adoption crops expressing Bacillus thuringiensis (Bt) proteins has led many cases resistance. Target-site mutations are among main mechanisms resistance monitoring their frequency is great value for insecticide management. Pyrosequencing PCR-based allelic discrimination assays were developed used genotype...
Pest management is mostly accomplished by the use of insecticides. However, overuse insecticides has led to development resistance. Glutathione S-transferases (GSTs) are vital detoxification enzymes involved in insecticide resistance insects. In this study, we report involvement GSTs lambda-cyhalothrin Cydia pomonella, a globally quarantined fruit pest. A total 25 GST, including 22 cytosolic genes and 3 microsomal genes, identified from genome database C. pomonella. These further classified...
The codling moth Cydia pomonella (Lepidoptera: Tortricidae) is a major invasive pest of pome fruits and walnuts worldwide. Lambda-cyhalothrin (LCT) abamectin (AM) have been frequently used in C. control, but control this very difficult because shortly after hatching, larvae insect bore tunnels hide inside host plant fruit. In study, simulated field spray bioassay method was developed against neonate concentration-response bioassays were conducted to evaluate the susceptibility LCT AM....
The fall armyworm (FAW) Spodoptera frugiperda is a severe economic pest of multiple crops globally. Control this often achieved using insecticides; however, over time, S. has developed resistance to new mode action compounds, including diamides. Previous studies have indicated diamide complex developmental process involving detoxification genes. Still, the mechanism underlying possible involvement microRNAs in post-transcriptional regulation not yet been elucidated. In study, global screen...
Abstract BACKGROUND: The codling moth is one of the principal pests apple in world. Resistance monitoring crucial to effective management resistance moth. Three populations neonate larvae were evaluated for seven insecticides via diet bioassays, and compared with a susceptible population. In addition, plots treated labeled field rate doses four insecticides. Treated fruit exposed two from commercial orchards. RESULTS: Two expressed two‐ fivefold azinphos‐methyl, seven‐ eightfold phosmet,...
Abstract BACKGROUND Arthropod pests are widely perceived to evolve resistance insecticides at different rates. Although widespread “successful” species assumed quickly and minor slowly, few studies have utilized published data on events test for differences among species. Using 532 records from the Pesticide Resistance Database covering 20 species, we applied a survival analysis model number of generations insecticide introduction first report arthropod resistance, providing one most...
Abstract BACKGROUND The invasive drosophilid pest, Drosophila suzukii Matsumura, is affecting berry production in most fruit‐producing regions of the world. Chemical control dominant management approach, creating concern for insecticide resistance this pest. We compared susceptibility D. populations collected from conventional, organic or insecticide‐free blueberry sites. RESULTS sensitivity to malathion and spinetoram declined slightly across 3 years monitoring, whereas it was more...
Abstract BACKGROUND Recent work has shown that two codling moth ( Cydia pomonella ) glutathione S ‐transferase genes (GSTs), CpGSTd1 and CpGSTd3 , can metabolize λ‐cyhalothrin, one of the recommended insecticides for C. control worldwide. However, systematical characterization delta epsilon GSTs, especially their potential contributions in metabolism is currently still lacking . RESULTS In this study, a total nine cDNA sequences were identified including four five subclasses. RT‐qPCR showed...
The fall armyworm (Spodoptera frugiperda) is one of the most destructive pests corn. New infestations have been reported in East Hemisphere, reaching India, China, Malaysia, and Australia, causing severe destruction to corn other crops. In Puerto Rico, practical resistance different mode action compounds has cornfields. this study, we characterized inheritance chlorantraniliprole flubendiamide identified possible cross-resistance cyantraniliprole cyclaniliprole. Rican (PR) strain showed high...
Rapid evolution of pest, pathogen, and wildlife populations can have undesirable effects, for example, when insects evolve resistance to pesticides or fishes smaller body size in response harvest. A destructive invasive species the Laurentian Great Lakes, sea lamprey (Petromyzon marinus) has been controlled with pesticide 3-trifluoromethyl-4-nitrophenol (TFM) since 1950s. We evaluated likelihood evolving TFM by (i) reviewing life history control; (ii) identifying physiological behavioural...
