Özet The tomato leafminer, Tuta absoluta (Lepidoptera), a destructive and invasive pest of tomatoes, is mainly controlled through the use of chemical insecticides. Altough diamide insectides, such as chlorantraniliprole with novel mode of action, have newly been registered, they have been intensively used because of their high efficacy level at low rates. However, their intensive use has led to the development of resistance. High levels of chlorantraniliprole resistance have recently been described in T. absoluta populations in Greece, Italy, Brazil, Spain and Isreal. In the present study, biological and molecular methods were used to determine the susceptibility of one field collected T. absoluta strain from Turkey, Antalya to chlorantraniliprole. High level of resistance was observed exhibiting (LC50: 813.522 [478.596 – 1807.186, in ppm]). To investigate whether chlorantraniliprole resistance was mediated by point mutation on ryanodine receptor (RyR) in T. absoluta, we sequenced partial RyR gene containing mutation sites recently shown to confer chlorantraniliprole resistance. This revealed the prescence of G4903E and I4746M mutations and supports the suggestion that control failures in Turkey especially in Antalya, in part, due to mutations on RyR target-site. Involment of detoxification enzymes should also be investigated. Areas used chlorantraniliprole against T. absoluta should be monitored to minimize the risk of rapid selection for high levels of resistance and to surpress the further spread of resistant populations, insecticide resistant management strategies should be adapted.
