Particle films for managing arthropod pests of apple
Journal of Economic Entomology 101 (1), 145-150
Abstract: A two-season study showed that a calendar-based spray program to manage arthropod pests with kaolin (60 g/liter) applied at the rate of 450 liters/ha was effective against European apple sawfly, Hoplocampa testudinea (Klug) (Hymenoptera: Tenthredinidae); white apple leafhopper, Typhlocyba pomaria McAtee (Homoptera: Cicadellidae); apple red bug, Lygidea mendax Reuter (Heteroptera: Miridae); pear plant bug, Lygocoris communis (Knight) (Heteroptera: Miridae); and the apple rust mite, Aculus schlechtendali (Nalepa) (Acari: Eriophyidae). Although it reduced Curculionidae damage, the level of damage was still too high. It had no effect on apple maggot, Rhagoletis pomonella (Walsh) (Diptera: Tephritidae); codling moth, Cydia pomonella (L.) (Lepidoptera: Tortricidae); and tarnished plant bug, Lygus lineolaris (Palisot de Beauvois) (Heteroptera: Miridae). Laboratory studies showed fewer gravid twospotted spider mites, Tetranychus urticae Koch (Acari: Tetranychidae), and fewer eggs laid by these females. The study also showed no effect of kaolin on Neoseiulus fallacis (Garman) (Acari: Phytoseiidae).
