- Abstract
Relative toxicity of some acaricides to the predatory mite, Phytoseiulus macropilis Banks and the two spotted spider mite, Tetranychus urticae Koch (Acari: Phytoseiidae, Tetranychidae) was evaluated under laboratory conditions. According to IOBC toxicity classification, all of the tested acaricides were slightly harmful to the predator's females. Six of the acaricides tested: abamectin, bifenazate, chlorfenbyer, hexythiazox, pyridaben and sulfur, were less toxic to adult females of P. macropilis than T. urticae at LC50 values. Hexythiazox was the most effective compound on egg hatching of T. urticae, hence hatchability was 35.5%, while 62.22% of predator eggs hatched. All of the tested acaricides caused low mortality rates to eggs of the predator (R=1.05 with hexythiazox). Abamectin, bifenazate, chlorfenbyer, hexythiazox, pyridaben and sulfur appeared to be promising candidates for use in integrated mite management programs.
