Contributo per la gestione della resistenza in Cydia molesta: sensibilità di base a triflumuron

Cydia molesta (Busck) is a serious pest in peach fruit orchards in Italy. Insecticides acting on insect specific metabolic targets like chitin synthesis inhibitor are now greatly preferred in several Italian integrated pest management guidelines. An increase in the use of an insecticide is also an increase in the risk of resistance towards the same product. To evaluate the baseline susceptibility to triflumuron of the eggs and of the mature larvae of C. molesta, a series of bioassays have been performed. Results of these bioassays will be useful in the future to evaluate any changes in susceptibility to triflumuron in wild populations of the Oriental Fruit Moth
