利用德宏边境口岸10年的实蝇监测数据,从实蝇种类、种群数量和结构动态变化方面分析实蝇发生发展情况。结果如下:(1)10年间德宏地区共监测鉴定出13种实蝇,其中种群数量最多的是桔小实蝇、瓜实蝇和南瓜实蝇;(2)3种主要实蝇10年来发生数量呈上升态势,2009年增速最快,1年监测到的实蝇占10年总量的28.1%;(3)桔小实蝇已经成为德宏地区最大的优势种群,到2009年,它在3种主要实蝇中已占79.0%的绝对多数,增速也最快。
Based on 10-year monitoring data of fruit fly from the Dehong border crossing, the occurrence and development of fruit fly were analyzed from the aspects of fruit fly species, population quantity and dynamic changes of structure. The results are as follows: (1) Thirteen fruit flies were detected and identified in Dehong during the past 10 years. Among them, Drosophila melanogaster, fruit flies and pumpkin fruit flies were the most abundant. (2) Three major fruit flies occurred in 10 years The number of fruit flies accounted for 28.1% of the total in 10 years. (3) The fruit flies have become the largest dominant population in Dehong area. By 2009, it has reached the highest growth rate In the three main fruit flies have accounted for 79.0% of the absolute majority, the fastest growth.
