Nesting biology of the stem‐nesting wasp Psenulus interstitialis Cameron (Hymenoptera: Crabronidae: Pemphredoninae) on Magnetic Island, Queensland
Abstract Psenulus interstitialis constructed nests of up to 10 cells in bamboo internodes on Magnetic Island, Queensland. Prey represented five families of Auchenorryncha, primarily late‐instar nymphs. Fully provisioned cells held 9–13 prey. Development required about 30 days, and the reared sex rat...

| Summary: | Abstract Psenulus interstitialis constructed nests of up to 10 cells in bamboo internodes on Magnetic Island, Queensland. Prey represented five families of Auchenorryncha, primarily late‐instar nymphs. Fully provisioned cells held 9–13 prey. Development required about 30 days, and the reared sex ratio was male biased at 2:1. There are probably several generations a year at this latitude. The three species of chalcidoid parasitoids reared, Leucospis giraulti Bouček, Eupelmophotismus pulcher (Girault) and Calosota sp., all attacked late‐larval or early pupal stages. Additional mortality was caused by a species of Pyemotes mite and an unidentified fungus. This is the first biological information for any Australian species of Psenulus . |
