Predator-Unfriendly Pesticides Harm the Beneficial Mite Neoseiulus idaeus Denmark & Muma (Acari: Phytoseiidae)

Pesticides are commonly used to control weeds, diseases, and pests in soybean crops, although natural enemies also key components of integrated pest management programs protecting from pests. The predatory mite Neoseiulus idaeus Denmark & Muma is found soybeans associated with tetranychid mites. We determined the compatibility some pesticides Brazilian fields N. on basis their lethal sub-lethal effects. assessed acute toxicity that considered harmless females evaluated effects offspring. Acephate as well imidacloprid bifenthrin were most toxic adult classified harmful. Chlorfenapyr, indoxacarb, neonicotinoid pyrethroid mixtures slightly moderately Immatures able develop reach stage when treated chlorantraniliprole, flubendiamide, glyphosate, teflubenzuron, but immature survival was reduced 42 64% for offspring chlorantraniliprole or respectively. Reproduction affected exposed teflubenzuron; these had daily oviposition rates 0.5 0.4 egg/female/day, respectively, mean fecundities 2.7 5.8 eggs/female, On sublethal life table parameters, harmful, while other tested harmless. In considering use targeting conservation a predator important one must prioritize will likely have less harmful this field.
