Abstract

Trichogramma nubilale Ertle and Davis females were offered a choice between egg masses of the European corn borer, Ostrinia nubilalis (Hübner), infected with the microsporidium Nosema pyrausta (Paillot) and non-infected egg masses. Nosema pyrausta-infected O. nubilalis eggs were smaller (weight) than non-infected host eggs. Trichogramma nubilale females did not discriminate between infected and N. pyrausta-free egg masses. This microsporidian infection did not significantly affect the sex ratio of emerging wasps. Significantly fewer and smaller adult parasitoids emerged from infected host eggs than from noninfected eggs.
