Özet
A scelionid egg parasitoid, Trissolcus simoni (Mayr), was investigated by exposing different host eggs to parasitism by females in order to assess the role of this alternative host species in the biological control of the sunn pest Eurygaster integriceps Puton. Egg masses of laboratory colonies of four field-collected host species were used in the experiments. Parasitism rates of E. integriceps, Dolycoris baccarum (L.), Graphosoma lineatum L. and Carpocoris pudicus (Pd.) averaged 86.8%, 81.6%, 82.8% and 84.0%, respectively. The parasitoid sex ratio and the percent of adult emergence did not differ significantly among the four hosts. The average development period was shorter in D. baccarum and C pudicus, with respective mean times of 10.3 and 10.8 days for females, and 9.2 and 9.6 days for males, than in E. integriceps and G. lineatum. According to these results, all the tested eggs were adequate hosts for T simoni development.
