The physiologies of insects and their fitness are significantly influenced by the specific microclimate they encounter. Insects could therefore be sensitive within short periods to climate change at the population level, such that the fingerprints of even early stages of climate change could be seen on insect population density and the number of generations. The oriental fruit moth, Grapholita molesta(Busck) (Lepidoptera: Tortricidae) is one of the important pests related to stone and pome fruits in Türkiye. Even at low population densities, G. molestacan cause economic damage and lead to crop losses of up to 50%. The aim of this study discusses the impact of climate data on the population of G. molesta. This study was conducted in the nectarine Prunus persicavar. nectarinaMaxim. (Rosales: Rosaceae) orchard with approximately 7‑year-old trees in Mersin province (Türkiye) between 2020 and 2022. The population fluctuation of G. molestawas studied using pheromone traps. In 2020, the pheromone traps were hung on the trees in orchards during the third week of May, whereas in 2021 and 2022, they were suspended during the third week of March. G. molestacaptures were recorded weekly from March/April to October/November. The progeny number of G. molestain our study was higher than in previous studies. Also, our findings demonstrated that the first adult emergence for G. molestawas earlier than in previous studies conducted. Our study demonstrated that not only the temperature but also precipitation and relative humidity have an effect on the population and progeny of G. molesta. |
