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,
It is very important to store the bee species in Trichogramma applications. Large area beekeeping requires accumulating a large number of bee species, requiring bee species to be stored for as long as possible and maintaining their viability and fertility. However, the breeding of Trichogramma often impatient cold storage, usually more than a month later the emergence rate is very low, poor life. Especially Trichogramma, which is dominated by rice moth, has been limited due to the fact that the long-term storage technology of moth eggs has not yet been completely solved. Therefore, improving the chilling resistance of Trichogramma and prolonging the effective storage period are of great significance to the expansion of the application. Since 1983, we have been
