摘要
本文对人工卵繁殖的螟黄赤眼蜂防治大豆食心虫室内和田间小区的防治效果进行评估。经过两年的试验，结果表明：人工卵繁殖的螟黄赤眼蜂与柞蚕卵繁殖的螟黄赤眼蜂对大豆食心虫的寄生效果无明显差异。准确把握放蜂时间是利用人工卵蜂防治大豆食心虫的关键技术环节之一。
Comparison test has been carried out in the indoor and plots covered between Trichogramma Chilonis. bred by artificial host eggs and that bred by oak silkworm egg:s for two years. The results indicated that the difference of controlling effect was not obvious between Trichogramma Chilonis bred by artificial host eggs and that bred by oak silkworm eggs. It is one of the key technique for controlling Leguminivora Giycinivorella to release the Trichogramma Chilonis at the right time.
