随着生物防治工作广泛而深入的开展,白僵菌在农林业生产实践中已用于防治多种害虫,但在防治杨干象虫等杨树蛀干性害虫方面,国内外还缺乏经验。为积极探讨利用白僵菌防治杨干象虫的途径,1977年以来,在过去研究的基础上,通过菌种分离、纯化、扩大培养、致病力测定以及生产防治试验,已初获结果。现将生产防治试验结果,简要整理如下:生产防治试验,是于1978年6月19日至7月10日在辽宁省法库县三尖泡林场10亩3年生北京杨林地中进行的。所用菌剂为1977年从被白僵菌寄生的蝙蝠蛾幼虫虫体
Beauveria bassiana has been used to control many kinds of pests in the practice of agriculture and forestry production with the extensive and in-depth biological control. However, Beauveria bassiana has been lacking in domestic and foreign experience in preventing and controlling poplar stem borers like dry yellows. In order to actively explore the ways of using Beauveria bassiana to prevent and cure Eleutherosides, since 1977, on the basis of previous studies, preliminary results have been obtained through the experiments of strain separation, purification, expansion, pathogenicity determination and production control. Now the production of control test results, a brief summary is as follows: Production control test, is in June 19, 1978 to July 10 in Faqin County, Liaoning Province, three-pointed bubble forest farm 10-year-old Beijing Yanglin in the land. The bactericide used was a bat moth larvae parasitized from Beauveria bassiana in 1977
