Insecticide susceptibility and resistance in populations of pear psylla, Psylla pyricola Foerster, and the mirid predator, Deraeocoris brevis Knight, were evaluated through biochemical and computer simulation analyses. Pear psylla were resistant to a

The cause of parathion and propoxur resistance inTyphlodromus pyri was studied in a Dutch strain in which resistance was dependent on a semi-dominant gene. Activity of glutathione S-transferase and acetylcholinesterase and reaction rate of acetylchol

Phytoseiulus persimilis and Metaseiulus occidenlalis are efficient predators of the two- spotted spider mite, Tetranychus urticae. Amblyseius potentillae and Amblyseius finlandicus are known to effectively control the European red spider mite, Panony

Codling moth, Cyndia Pomona ella (L.), from pear in the Bedford, Oreg., area showed resistance to the chitin synthesis inhibitor diflubenzuron in laboratory and orchard studies. In the orchard this was shown in 1984 and 1985 as 54.5-63.6% damage at h

Among tetranychid spider mites and their phytoseiid predators, the evolution of pesticide resistance is a common event. In most cases, resistance is based on a single dominant or semidominant gene. However, polygenic, less-stable resistance often dev

Fenvalerate resistance was monitored in Psylla pyricola Foerster populations at 51 sites in Washington, Oregon, California, and British Columbia during early 1988. Resistance levels ranged from susceptible in an organic orchard in the Willamette Vall
