Abstract:

Carposina sasakii (Lepidoptera: Carposinidae) is one of the most dangerous pest in fruit production in northern China. It has the characteristics of a wide range of occurrence, a variety of fruit tree hosts, serious economic losses, and difficult prevention and control. The first emergence time and population dynamic trend of C.sasakii adults in orchards are generally used as an important reference basis for its control. It is beneficial to construct pest control strategies in fruit tree production, and to effectively control the population of C. sasakii in orchards. In order to master the happening dynamic of C.sasakii in the apple producing areas of Liaoning province, the present dataset was generated by collecting the daily occurrences of adult C.sasakii from 2019 to 2021 at a fixed point by hanging a sex bait trap in the apple garden to form this dataset. This dataset could provide a scientific reference for further clarification of the biology and ecology of C.sasakii, and provide a detailed data basis for green, efficient and precise control of C.sasakii.

Key words: Carposina sasakii, adult, population dynamic, apple
