通过对云南杨梅主产区的果蝇种类鉴定、栖息场所及危害发生规律调查,结果表明:危害云南杨梅果实的主要害虫为双翅目(Diptera)果蝇科(Drosopilidaes)果蝇属(Drosophila)果蝇。果蝇广泛分布于杨梅园及其周边多种生态环境,具有发酵物、潮湿阴凉的生态环境,是果蝇栖息的主要场所和主要虫源;成虫的日活动高峰期为清晨和黄昏;果蝇对杨梅发生危害时期较早,杨梅生长中后期,果实肉质生硬,味酸稍甜时即被果蝇取食危害,随着杨梅的不断成熟,危害加剧,且果蝇对不同杨梅品种的危害程度和空间分布存在显著差异。
The results showed that the main pests harmful to the fruit of Myrica rubra were Diptera, Drosophila, Drosopilidae, Drosophila, Drosophila, Drosophila. Drosophila are widely distributed in the Yangmei Garden and its surrounding a variety of ecological environment, with fermentation, moist and cool ecological environment, is the main habitat of Drosophila and the main source of insects; adult peak daily activity of early morning and evening; fruit fly Myrica rubra occurs earlier, the mid-and late-growth of bayberry, fruit flesh hardened, slightly acidic when the fruit flies eat dangerous, with the continuous maturation of red bayberry, the increased risk, and the flies on different varieties of red bayberry and There are significant differences in spatial distribution.
