前言近年来已普遍使用白僵菌防治松毛虫,并收到了一定效果。而由于白僵菌抵抗不良环境(干旱)的能力差和菌种退化,给当前的白僵菌生产和对松毛虫防治造成一定影响。为此,我们对广东、广西、福建、江西等地使用的白僵菌,以目前通常采用的培养基进行培养,了解现用菌是否有不同的类型和较好的培养基,达到初步的选优作用。然后在较好的培养基上用类型较优的菌进行人工定向培育和诱变育种,来提高白僵菌对环境适应能力;提高杀虫效果。但我们的工作还只做了前一部分,为交流情况,互相促进,提供参考。
Foreword In recent years, Beauveria bassiana has been widely used to control pine caterpillars and has received some results. Beauveria bassiana against poor environment (drought), poor ability and strain degeneration, to the current production of Beauveria bassiana and the impact on the prevention and control of pine caterpillars. To this end, Beauveria bassiana, used in Guangdong, Guangxi, Fujian and Jiangxi provinces, is cultivated in the currently commonly used culture medium to find out whether there are different types and better culture media for the active bacteria to reach the preliminary selection Excellent effect. And then use better type of bacteria on the better medium for artificial orientation breeding and mutation breeding to improve Beauveria bassiana adaptability to the environment; improve insecticidal effect. However, we have only done the first part of our work to provide reference for exchanging information and promoting each other.
