Abstract: The non-target effects of acaricides, used against Aceria guerreronis (Acari: Eriophyidae) the coconut mite, on its natural enemies are not known. Therefore we assessed the susceptibility of A. guerreronis and its predator Neoseiulus baraki (Acari: Phytoseiidae) to selected acaricides, their impact on N. baraki rate of increase, and the synergism of fenpyroximate towards this predator. Toxicity bioassays and synergism of fenpyroximate (with piperonyl butoxide, triphenyl phosphate and diethyl maleate) were performed by spraying the mites under a Potter tower. The instantaneous rate of increase (r i ) was calculated ten days after spraying the predator. Chlorfenapyr and fenpyroximate were selective (both LC50 and LC90 were higher for N. baraki than for A. guerreronis) and did not affect the predator r i . Only piperonyl butoxide significantly synergized fenpyroximate suggesting the involvement of cytochrome P450 monooxygenase in the N. baraki tolerance. Fenpyroximate and chlorfenapyr are promising agents for managing A. guerreronis in combination with N. baraki because both are selective and do not affect its predator r i .
