Population Dynamics of (Diptera: Tephritidae) in Four Counties of Yunnan, China, by Electronic Monitoring System.

(Hendel) (Diptera: Tephritidae) is a global economic pest that poses a serious threat to the fruit industry. In the southwest of China, Yunnan Province sustains a severe infestation of . An automated monitoring system designed for was employed in this study to elucidate the annual population dynamics of in four counties: Yuanjiang, Huaping, Guangnan, and Ludian in Yunnan. The system utilizes sex parapheromone and image recognition technology. The data uploaded by the device are used to analyze the annual population dynamics of in different regions. The results showed that the populations of adult in all four counties peaked twice annually, with Yuanjiang experiencing the earliest peak periods, followed by Huaping, Guangnan, and Ludian. Adult occurred in Yuanjiang throughout the year, and Yuanjiang had the highest number of monitored. In Huaping, adult occurred in March-December and was highly active, with a high population density in 2019. did not occur in December in Guangnan but only in May-October in Ludian. abundance was correlated with temperature in all four areas. The outcomes of this experiment provide a practical foundation for developing control strategies targeting in various orchards across each county.
