蝇类是一种重要的医学昆虫,它能傅播多种重要的傅染病。要使防制蝇类收到事半功倍之效,必须根据不同蝇类的生态习性而采取合理的防制措施。现将我国主要蝇类的生态习性及其鉴别要点简述如下。一、蝇的生活史蝇类的生活史属完全变态,分卵、幼虫(蛆)、蛹、成虫四期。完成一个世代发育所需时间的长短,受气温的影响很大:气温高,需时短;气温低,需时长。如30℃约需8～12天;12℃约需20天。通常,一个夏季可完成7～8个世代发育。
Flies is an important medical insect, which can spread a variety of important Fu disease. In order to make prevention and control of flies more effective, it is necessary to take reasonable control measures according to the ecological habits of different flies. The ecological habits of major flies in China and their main points are summarized as follows. First, the life history of flies Flies living history is completely metamorphosis, eggs, larvae (maggots), pupae, adult four. The length of time required to complete a generational development is strongly influenced by temperature: high temperatures, short durations, low temperatures, and long durations. Such as 30 ℃ about 8 to 12 days; 12 ℃ about 20 days. Usually, one summer can complete 7 to 8 generations of development.
