研究方法1.蜂种的收集从各期玉米螟卵出现时开始。每隔3天采集一次。并不定期采集松毛虫、三化螟及其他害虫的卵块或卵粒。同时结合赤眼蜂年终野外发生消长情况调查,在野外悬挂松毛虫卵片等方法.收集自然界赤眼蜂种类,在室内进行饲养观察。2.生物学特性观察观察一律在25℃的定温室内进行。将收集的各种赤眼蜂待其羽化交尾后,引出母蜂。个别饲养于指形管中,供给适量的饲料.并逐日供给新鲜的松毛虫或小地老虎卵粒.使之产卵.观察并记载其
Research Methods 1. Collection of bee species began with the emergence of each stage of the corn borer eggs. Gather once every 3 days. Not regular collection of pine caterpillars, rice stem borer and other pests eggs or eggs. At the same time, combined with the occurrence and growth of Trichogramma at the end of the field investigation, in the wild hanging Dendrolimus ovum and other methods collected in the nature of Trichogramma species, observed indoors feeding. Observation of biological characteristics observed in 25 ℃ constant temperature room. The collected Trichogramma awaits its eclosion and leads to the queen bee. Individually housed in the fingers of the tube, to provide a suitable amount of feed, and fresh daily supply of pine caterpillars or tiger tiger eggs to spawn observed and documented
