摘要:
影等鳃金龟幼虫对多种农作物、花卉苗木等根及幼苗危害大。作者对收集的20株绿僵菌产孢量情况进行了计量，筛选出产孢量高的Ma42，Ma788，Ma789 3个菌株，并进一步开展了3菌株对影等鳃金龟幼虫的毒力及耐高温性测定。结果表明Ma789菌株的致病力较强，注喷处理30 d后，感染率达43%；Ma788菌株的耐高温性较强，40 ℃水浴处理12 h后，孢子萌发率仍在33%以上。供试验的3菌株毒力和耐高温性未表现出一定的相关性。
Abstract:
Exolontha umbraculata larva is harmful to the roots and seedlings of many crops. Sporulation quantity of 20 Metarhizium anisopliae strains were measured in this paper, and then Ma42，Ma788，Ma789 were screened out with high yield of spore. Furthermore, their virulence against Exolontha umbraculata larva and high temperature resistance were also determined. The results showed that Ma789 was the most virulent in 30 days after injection, with infection rate of 43%. And Ma788had the highest temperature resistance since after 40 ℃ water bath treatment for 12 h, it still got more than 33% of spore germination rate. We concluded that there was no correlation between virulence and high temperature resistance of 3 strains tested.
