Field and laboratory experiments on the response and development of resistance to pesticides and population density ofTetranychus cinnabarinus in ISRAEL

Abstract

Dosage mortality data for 12 pesticides were determined with females of an insecticide-susceptible strain of the carmine spider mite,Tetranychus cinnabarinus (Boisd.), by the slide dip method; for four of the pesticides which are specific acaricides, also the Munger cell method was used. The LC50s ranged from 0.00078% to 0.041%, with the synthetic pyrethroids being more toxic than the specific acaricides. There were no differences in results between the two assay methods.
