Survey of codling moth organophosphate resistance and associated tolerances to other pesticides
نویسندگان
چکیده
1. Levels of azinphosmethyl (Guthion) resistance were low to moderate in codling moth populations throughout the state. 2. Populations high enough to screen against multiple chemistries had only low levels of resistance, preventing meaningful cross-resistance data for pyrethroids or chlorpyrifos (Lorsban). 3. A population with high azinphosmethyl resistance was identified near Manson during secondgeneration flight. 4. There is potential cross-resistance with acetamiprid (Assail), although the data are too variable to be conclusive.

Pome Fruits—Pesticide Resistance Detection and Characterization of Resistance to Pesticides in Codling Moth in Oregon
No field failure of azinphosmethyl had been noticed in controlling codling moth from Oregon until 1989. However, in a study conducted by Moffitt et al. during 1986 to 1987, a codling moth population from Medford has been reported resistant to diflubenzuron. It was suspected that selection by other commonly used compounds was probably responsible for this resistance. We initiated our work in 198...
متن کاملResistance Management Update on Organophosphate Resistance in Codling Moth
In 2003, organophosphate (Guthion) resistance was surveyed in codling moth from populations throughout Washington State. Populations were collected using pheromone traps during first and second flights from apple and pear and sampled for Guthion resistance using the standard adult topical bioassay. Select populations were also sampled for pyrethroid and chloronicotinyl resistance. All orchards ...
متن کاملResistance of codling moth, Cydia pomonella (L.) (Lepidoptera: Tortricidae), larvae in Michigan to insecticides with different modes of action and the impact on field residual activity.
BACKGROUND The codling moth is one of the principal pests of apple in the world. Resistance monitoring is crucial to the effective management of resistance in codling moth. Three populations of codling moth in neonate larvae were evaluated for resistance to seven insecticides via diet bioassays, and compared with a susceptible population. In addition, apple plots were treated with labeled field...
متن کاملBaculovirus resistance in codling moth is virus isolate-dependent and the consequence of a mutation in viral gene pe38.
The baculovirus Cydia pomonella granulovirus (CpGV) is widely applied as a biocontrol agent of codling moth. After field resistance of codling moth populations had been observed against the commercially used Mexican (M) isolate of CpGV, infection experiments of larvae of the resistant codling moth strain CpRR1 showed that several other naturally occurring CpGV isolates (I12, S, E2, and I07) fro...
متن کاملMultiple Origins of the Sodium Channel kdr Mutations in Codling Moth Populations
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 in domain II) was investigated in order to estimate resistance evolution to pyrethroid in codling moth populations at the World level. DNA variation among 38 sequences revealed a unique kdr mutation (L1014F) invol...
