Impacts of field rates of selected insecticides on the predatory mite, Neoseiulus californicus (McGregor) (Acari: Phytoseiidae), were evaluated in laboratory bioassays. In topical treatments with chlorantraniliprole, flonicamid, flubendiamide, indoxacarb, metaflumizone, pymetrozine, spinetoram, and thiacloprid, 86–92% of N. californicus adult females survived 168 h after exposure. Females exposed to the insecticides produced 86–98% as many eggs as did the females in the controls, and eclosion of eggs was not affected. Moreover, the percentage of eggs that hatched, and larval survival following direct exposure to the insecticides, were not reduced. Immature N. californicus survived on leaf discs with insecticidal residues, with 94–98% reaching adulthood. Based on these results, these insecticides evaluated in these laboratory bioassays are promising candidates for use in integrated pest management programs where N. californicus is a natural enemy.
