【摘要】 以新疆准噶尔盆地南缘区域为调查点，应用昆虫系统调查法进行羊鼻蝇生活史调查，并对其各虫态期进行了测算和分析。结果发现：羊鼻蝇幼虫的百分比曲线呈不等称双峰型，发育速率时快时慢，冬季有滞育现象；该地区羊鼻蝇的发生世代为１ ａ ２ 代，２ 代所用时间不等，且世代重叠更多还原

【Abstract】 Generation of the sheep bot fly, Oestrus ovis had been studied with entomological system investigation and its instar stage had been estimated and analysed in the southern border area of Zhungeer Basin. The results were summarized as follows: 1.
