在开展育蜂治虫过程中,赤眼蜂越冬保种是一个极其重要的环节。只有搞好越冬保种,春季才能获得大批蜂种,进行大量连代繁殖,以达到大面积放蜂的目的。我们遵照毛主席关于‘实践、认识、再实践、再认识”的伟大教导,从1966年开始进行赤眼蜂越冬保种实验,现将实验情况简单总结于后: During the process of breeding beekeeping insects, Trichogramma overwintering preservation is an extremely important link. Only do a good winter maintenance of species, the spring can get a large number of bee species, a large number of even the generation of reproduction, in order to achieve the purpose of large area beekeeping. Following the great teachings of Chairman Mao about ’practice, understanding, re-practice and re-understanding’, we started experimenting with the maintenance of the trichogramma overwintering from 1966. Now we summarize the experimental situation briefly:
