Resistance Management A 40-Year Experiment: Codling Moth’s Responses to Guthion and Other Insecticides
The response of adult male codling moth to Guthion was surveyed in 20 orchards using a discriminating concentration (0.3 μg/moth) during 2003. A wide range of responses was found with 17 of the populations being statistically categorized as tolerant to Guthion versus our laboratory population. The post-diapause emergence of six populations was measured and a strong correlation was found between...
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 کاملSurvey of codling moth organophosphate resistance and associated tolerances to other pesticides
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 sec...
متن کاملClassical Biological Control of Codling Moth: the California Experience
Codling moth is a notorious fruit-boring pest that has extended its original distribution from the natural apple forests of Central Asia to cover all apple growing regions of the world. Having been discovered in California as early as 1872, codling moth has continued to be the dominant pest of apple, pear and walnut production causing extensive damage in the absence of insecticide treatment. In...
متن کاملStudy of Factors Affecting Codling Moth Control by Mating Disruption
This year was the first year of a multiyear project to examine a. number of factors associated with the chemistry of codling moth mating disruption. A substantial portion of time and manpower was involved in building the apparatus required for the project and developing and troubleshooting methods required for the duration of the project. We are about three months behind schedule; we hope to ha...
