| 摘 要： | 1978—1983年,作者在河南省进行了早期低量释放赤眼蜂防治玉米螟和稻纵卷叶螟的试验。并与常规释放法作比较。早期低量释放区于4月下旬每亩释放500—1000头,常规释放区于5月底每亩释放10000头,第一代、第二代两种释放方法玉米螟卵块寄生率差异不显著。防治稻纵卷叶螟也得到相同结果。

| Abstract: | Field expsriments of inoculative releases of Trichogramma spp. in the early season against corn borer, Ostrinis furnacalia and rice leafroller, Cnaphalocrocia medinalis were conducted from 1977 to 1983 in an area of ca. 50,000 ha. in Kenan Province. The parasite was released in the Inoculative-release plots at a rate of 500-1,000 per mu (15 mu = 1 hectare) during late April, and in the Inundative-release plots at 10,000 per mu during late May. No significant egg parasitization of the 1st and 2nd generation corn borer was found between the two treatments. The result held true for the rice leafroller eggs, |
