Bemisia tabaci biotype B is present in Australia
Bemisia tabaci biotype B (EPPO A2 quarantine pest) was detected in Australia for the first time in 1994-10. The insects were identified by esterase isoenzyme patterns and were collected from cucurbit crops in Darwin (Northern Territory) and in a nursery at Tamworth (New South Wales). These populations of whiteflies were able to induce symptoms of silverleaf on cucurbits. Preliminary in vitro studies suggested that these populations might be highly resistant to organophosphorus and carbamate insecticides.
