Genetics, gene flow, and distribution of pesticide
resistance traits were examined for organophosphate (OP)
resistance in three beneficial phytoseiid mites. Levels
and genetics of OP resistance in Amblyseius andersoni
were examined first. Laboratory strains from Italy and
Oregon, USA, were compared in susceptibility to
insecticides used in western Oregon fruit...
Pesticides, including insecticides, acaricides, fungicides, bactericides, and herbicides are essential for maintaining healthy grape crops with reliable
yields and quality. In many instances, pesticides have become less effective as target organisms have developed resistance. The first record of resistance dates to 1897, when orchardists began having problems controlling San Jose...

A modified slide-dip bioassay was used to survey and establish
baseline resistance levels in Psylla pyricola Foerster from
western Oregon orchards to four pesticides. Orchards selected in the
Hood River, Rogue River and Willamette Valleys spanned a wide range of
environmental and management conditions. During the study period of
1982-1983,...
