摘　　要：在龙南县大猿叶虫是十字花科蔬菜上的重要害虫。在田间,该虫的繁殖期出现在春季和秋季,以成虫在土中越夏和越冬。本试验在25℃、LD12︰12条件下,详细比较了大猿叶虫龙南种群春季世代和秋季世代成虫产卵量。结果显示:秋季世代雌虫每雌总产卵量和平均产卵量均高于春季世代,早期产卵量接近,但三者间均无显著差异。由雌虫产卵曲线可知春季世代雌虫每日产卵量明显低于秋季世代,差异显著。The cabbage beetle, Colaphellus bowringi Baly is a serious pest of crucifers in Longnan county. Therare twodistinct infestation in the field, one occurs in spring, another in autume. The beetles enter summer and winter diapause in soil as adults. In the present study, the egg production between spring generation and autumn generation in this beetle were compared at 25℃, LD12 ： 12. The results showed that the total number of egg production and mean egg production of autumn generation were higher than those of spring generation, but the earlier egg production was near. However, there were no significant differences in egg production between spring generation and autumn generation. The ovipositing curves of spring generation and autumn generation suggested that egg production per female per day of autumn generation was obvious higher than that of spring generation.
