【摘要】 <正> 在赤眼蜂应用中蜂种的贮存是十分重要的,大面积放蜂需要积累大量的蜂种,要求蜂种尽可能长时间地贮存起来,并保持其生活力和繁殖力。但常规下繁殖的赤眼蜂往往不耐冷藏,一般一个多月以后羽化率就很低,生活力差。尤其是以米蛾卵为奇主的赤眼蜂,由于目前对米蛾卵的长期贮存技术尚未完全解决,蜂的应用更受到限制。因此,提高赤眼蜂的耐冷性,延长有效贮存期,对扩大应用有重要的意义。我们自1983年以来,更多还原

【Abstract】 Development of Trichogramma japonieum, T. confusum and T. nubilale, under fluctuating temperatures and photo-period (23+1℃, 16 hr. light; 12+2℃, 8 hr. dark) to prepupae or pupae could be stored at 7.5+1.8℃ or 3.7+1.6℃ for 3—4 months with effective rate of emergence and fecundity. At the same temperature of cold storage, these species of Trichogramma were stored only for 1 month, if they were developed under 26-28℃.更多还原
