目的了解上海共青森林公园内蝇类种群结构及季节消长,获得指导蝇类控制的基础数据。方法笼诱法。结果2007～2009年共捕获蝇类44种(隶属4科27属),优势种群为大头金蝇,占构成比70.69%;蝇类活动3月始现,12月逐渐消失。5月达全年最高峰,10月为次高峰。大头金蝇在5月份始现,10月达最高峰。结论上海共青国家森林公园种群丰富,优势种群大头金蝇是蝇类控制的主要种群;季节消长呈现双峰型,但不同蝇种群的季节消长亦不同,因此持续监测、活动高峰前幼虫孳生地的检查和清除及活动高峰期成虫的控制是该森林公园蝇类控制的关键。
Objective To understand the structure and seasonal fluctuation of flies population in Shanghai Gongqing Forest Park and obtain the basic data for the control of flies. Methods Cage induction method. Results A total of 44 flies (belonging to 27 genera and 4 families) were collected from 2007 to 2009, and the predominant population was Drosophila melanogaster, accounting for 70.69% of the total. Flies started in March and gradually disappeared in December. May reached the peak throughout the year, in October for the second peak. Goldfly occurs in May, reaching its peak in October. Conclusions Shanghai Gongqing National Forest Park is rich in population, and the dominant population is mainly dominated by flies. Seasonal fluctuation shows a bimodal pattern, but the seasonal fluctuation of different flies is also different. Therefore, the monitoring of the growth of pre-peak larvae The inspection and clearance and control of adults at the peak of activity are key to fly control in the Forest Park.
