摘  要：
为探讨以米蛾卵为中间寄主的稻螟赤眼蜂规模化繁殖技术,对不同蜂卵比及接蜂时间进行试验比较。结果表明:蜂卵比和接蜂时间对稻螟赤眼蜂的寄生率影响较大,对羽化率影响不明显,对雌蜂率没有影响。蜂卵比为1∶10、1∶15、1∶20时寄生率分别达到91.22%、90.49%和84.71%。蜂卵比为1∶10时接蜂时间24～36 h、蜂卵比为1∶15时接蜂时间36～48 h、蜂卵比为1∶20时接蜂时间48～60 h寄生率均较高。蜂种扩繁采用蜂卵比1∶10接蜂时间24 h,可提高蜂种羽化率,工厂化大量生产应采用蜂卵比1∶20接蜂时间48 h为宜。

摘  要：
In order to study large-scale reproduction technology of trichogramma japonicum with rice moth eggs as intermediate host. a comparison experiment was conducted different proportion of female trichogramma to host eggs and time for inoculation, The results showed that proportion of female trichogramma to host eggs and time for inoculation had a great effect on the percentage of parasitism, and had no obvious effect on the adult emergence rate not the effect on the percentage of the female wasp. The percentage of parasitism were 91.22%, 90.49% and 84.71% respectively when proportions of trichogramma to eggs were 1∶10, 1∶15, 1∶20. The percentage of parasitism were relatively high when proportion of female Trichogramma to host eggs and time for inoculation were 1∶10 and 24-36 h, 1∶15 and 36-48 h, 1∶20 and 48-60 h. We should adopt the proportion of female trichogramma to host eggs as 1∶10 and time for inoculation is 24 h in mass production of Trichogramma japonicum species, which can improve the adult emergence rate of Trichogramma species. The ratio of bee egg to bee egg should be 1∶20 for 48 h in mass production in the factory.
