【摘要】 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。更多还原

【Abstract】 Fruit fly is one of the major insects in Myrica rubra in Yunnan,the kinds,distribution,occurring regularity and damage of the insect were investigated in the study.Results showed that the insect was an uncleared species of Drosophila,widely distributed in Myrica rubra plant orchard and many surrounding environments,especially in shady,moist places and full of forments where were the main habitat and resource of food for the insect.The adult fly mostly emerged in early morning and dusk in the mid-later period of Myrica rubra growing,esp.during maturing stage.The damage degree and spatial distribution has significant difference between Biqi and Dongkui,two different Myrica rubra cultivars.更多还原
