赤眼蜂是多种害虫的卵寄生蜂,可利用它消灭害虫卵,防治害虫。赤眼蜂是怎样越冬的?在哪里越冬?国际上还没有专题报道过,这个问题既有理论意义,也有实际意义。我国农业战线上的科技工作者,经过多年的冬季野外调查发现,在秋末冬初的时候,赤眼蜂便寻找越冬寄主卵,产卵于其中,在寄主卵内发育到预蛹期而越冬。赤眼蜂发育时,将寄主卵内的营养物质消耗吸收完,到越冬时,寄主卵实际上只剩下卵壳。在淮北地区调查发现,柳毒蛾(又叫杨雪毒蛾)
Trichogramma is a variety of pests eggs parasitic wasps, which can be used to eliminate pests eggs, pest control. Trichogramma is how winter? Where the winter? There are no special reports on the international community, this issue has both theoretical and practical significance. After many years of field work in winter, scientists in the agricultural front in China found that during the late autumn and early winter, the red-eye bee looked for the overwintering host eggs to lay eggs in them, and developed the preophorous pupal stage in the host eggs to wintering. Trichogramma development, the host will be absorbed within the consumption of nutrients within the egg, to the winter, the host egg in fact only the egg shell. In Huaibei area survey found that Liu poison moth (also known as Yang Xue Tong moth)
