The selectivity of sixteen pesticides used in integrated and conventional peach production was evaluated on adults of Chrysoperla externa (Hagen,1861) (Neuroptera: Chrysopidae) under bioassays in laboratory conditions (temperature of 25±1ºC, relative humidity 70±10% and 14 hours photophase), using the "International Organization for Biological Control" (IOBC) methodology. The pesticides (% active ingredient) azoxystrobin (0.016), captan (0.192), dodine (0.126), pholpet (0.200), mancozeb (0.256), mancozeb + cooper oxichloride (0.140 + 0.096), tebuconazole (0.320), abamectin (0.002), mineral oil 1 (2.420), mineral oil 2 (1.920), paraquat dichloride (0.300) and gliphosate (1.440) were harmless; deltametrin (0.002) was slightly harmful and dimetoate (0.160), phosmet (0.160) and malathion (0.240), were harmful to C. externa adults.
