在昆虫病理研究中,病毒病不论就其理论意义,或就其在微生物防治中的实践意义来说,都具有重要的价值。因此,人们对于这一领域的兴趣与日俱增。 在探讨应用病毒防治作物害虫时,有必要首先在人工控制条件下研究病毒感染寄主的各种特点,作为实际应用的参考。 作者对黄地老虎Agrotis segetum Schiff.和麦穗夜蛾Hadena sordida Bkh.两种经济上较重要的害虫进行了病毒病人工感染试验,本文介绍几种昆虫病毒对这两种夜蛾幼虫的感染,混合感染的结果以及温度因子对发病的影响。 试验材料系采用在实验室饲养的卵块和Ⅲ、Ⅴ龄
In the study of insect pathology, viral diseases are of great value both in their theoretical significance and in their practical significance in the control of microorganisms. Therefore, people’s interest in this field is increasing day by day. When discussing the application of virus to prevent and control crop pests, it is necessary to study various characteristics of virus-infected host under the artificial control conditions first, as a reference for practical application. The authors tested Agrotis segetum Schiff. And Hadena sordida Bkh., Two economically more important pests and tested the virus infection in humans. In this paper, we described the infection of these two species of larvae by insects, The results of mixed infections and the impact of temperature on the incidence. Materials used in the laboratory test-keeping eggs and Ⅲ, Ⅴ age
