We examined effects of aerial application of acephate (Orthene), Bacillus thuringiensis variety kurstaki Berliner (Foray), and tebufenozide (Mimic) on larval/pupal parasitoids of the Nantucket pine tip moth, Rhyacionia frustrana (Comstock), in the southwestern Georgia coastal plain. Parasitism of tip moths in acephate-treated plots was significantly lower than in untreated plots. Bacillus thuringiensis and tebufenozide showed no significant effects on parasitism. A tachinid, Lixophaga mediocris Aldrich, comprised a significantly greater proportion of emerging parasitoids in acephate-treated than in untreated control plots, whereas a chalcidid, Haltichella rhyacioniae Gahan, was less abundant in the acephate-treated plots. Acephate has a negative, but somewhat species-specific, impact on tip moth parasitism.
