Abstract The codling moth Cydia pomonella , a major invasive pest of pome fruit, has spread around the globe in last half century. We generated chromosome-level scaffold assembly including Z chromosome and portion W chromosome. This reveals duplication an olfactory receptor gene ( OR3 ), which we demonstrate enhances ability C. to exploit kairomones pheromones locating both host plants mates. Genome-wide association studies contrasting insecticide-resistant susceptible strains identify...

Monitoring pesticide resistance is essential for effective and sustainable agricultural practices. Bioassays are the basis pesticide-resistance testing, but devising a reliable reproducible method can be challenging because these tests carried out on living organisms. Here, we investigated five critical parameters how they affected evaluation of to organophosphate phosmet or pyrethroid lambda-cyhalothrin using tarsal-contact protocol Drosophila suzukii, worldwide invasive pest. Three were...
In southern Brazilian apple (Malus spp.) orchards, predominantly organophosphates are used to control the oriental fruit moth, Cydia molesta (Busck) (Lepidoptera: Tortricidae), but failures often occur. Therefore susceptibility of three C. populations was investigated five insecticides different groups and modes action, in comparison with a susceptible laboratory strain mass reared France for >10 yr. At same time, comparative biochemical genetic analysis were performed, assessing activities...
The detection of resistance in codling moth (Cydia pomonella) populations against the Mexican isolate its granulovirus (CpGV-M), raised questions on sustainability use this biological insecticide. In resistant host cells, CpGV-M is not able to complete replication cycle because blocked at an early step. Virus isolates overcome have been characterized—among them, CpGV-R5 isolate. mixed infections insects, both and viruses replicate, while alone does induce mortality. Genetically heterogeneous...
We examined the role of most important metabolic enzyme families in detoxification neurotoxic insecticides on adult males and females from susceptible populations Cydia pomonella (L.), Grapholita molesta (Busck), Lobesia botrana (Denis & Schiffermüller). The interaction between - carboxylesterases (EST), glutathione-S-transferases (GST), polysubstrate monooxygenases (PSMO) with chlorpyrifos, λ-cyhalothrin, thiacloprid was studied. Insect mortality arising insecticides, application inhibitors...
The NPP-R1 isolate of CpGV is able to replicate on CpGV-M-resistant codling moths. However, its efficacy not sufficient provide acceptable levels control in natural (orchard) conditions. A laboratory colony derived from resistant moths was established, which exhibited a homogeneous genetic background and resistance level more than 7000 fold. By successive cycles replication this colony, we observed progressive increase efficacy. After 16 (isolate 2016-r16), the virus equivalent that CpGV-M...
The codling moth, Cydia pomonella, is a major pest of apple and pear orchards.However, with intensive use pesticide, an increasing number resistances has been reported.Detoxification one the main mechanisms involved in resistance Lepidoptera, there still much to discover about molecular underlying it.This study was conducted decipher insecticide C. pomonella identify genetic markers associated upon exposure several pesticides.To that aim, experimental evolution carried out from wild...
Resistance to insecticides is one interesting example of a rapid current evolutionary change. DNA variability in the voltage-gated sodium channel gene (trans-membrane segments 5 and 6 domain II) was investigated order estimate resistance evolution pyrethroid codling moth populations at World level. variation among 38 sequences revealed unique kdr mutation (L1014F) involved this region, which likely resulted from several convergent substitutions. The analysis samples 52 apple orchards 19...
Background In 2004, resistance to a commercial formulation of the Cydia pomonella granulovirus (CpGV) was identified in field population from an organic orchard southern France. The genetic inheritance this analysed resistant laboratory strain RGV. This obtained using successive crosses between and susceptible strain, SV, with selection for CpGV at each generation. Results After eight generations introgression trait into RGV-8 exhibited 7000-fold higher than SV. Mass-crossing experiments...
The European corn borer (Ostrinia nubilalis (Hübner)) is one of the most serious pest in Europe where it controlled with pesticides, particular, pyrethroids. First control failures this chemical family occurred on field 2008 center France, and first resistance case was described 2012. In present study, we investigate mechanisms involved seven French populations O. collected field. Resistances to deltamethrin lambda-cyhalothrin were confirmed, a higher ratio for (63.79 compared 7.67)....
The utilization of insect pest pathogens as biocontrol agents can serve an effective alternative to chemical pesticides.However, pests develop resistance these pathogens, similar observed with chemicals.Identifying the genetic bases is a crucial step in comprehending co-evolution mechanisms between hosts and their thereby enhancing durability methods.Cydia pomonella, major apple pear trees found across all continents, be effectively controlled commercial orchards through use granulovirus,...
