Abstract: The selectivity of carbaryl, deltamethrin, methyl parathion, permethrin and thrichlorfon to the predator Polybia ignobilis (Haliday) was evaluated in dosages which killed 90% of 4th and 5th instars of Ascia monuste orseis (Godart). Methyl parathion (86% average mortality) and carbaryl (62%) were not selective to P. ignobilis; thrichlorfon and permethrin (4%) were more selective while deltamethrin showed intermediate selectivity (26% average mortality). Adults of P. ignobilis with yellow stripes (38%) were more tolerant to carbaryl than those without this characteristic (86% average mortality).
