染毒方式对球孢白僵菌侵染茶卷叶蛾毒力的影响
Effect of Inoculation Method on Toxicity of Beauveria bassiana against 5th Instar Larvae of Homona coffearia
摘要
Abstract
Toxicities of Beauveria bassiana strains, JYBb201 and JYBb202, against the 5th instar larvae of Homona coffearia were compared when 4 different methods of inoculation were applied. The adjusted mortality rates of H. coffearia larvae subjected to 1. OX 107 conidia · mL-1 spore suspensions of JYBb201 and JYBb202 were found to be 85.00% and 81.94%, respectively, when the larvae were submerged in the spore suspension; 82.50% and 76.94%, respectively, when the larvae were smeared with the spore suspensions 47.50% and 43.61%, respectively, when the tea tips were dipped in the suspension; and, 52. 50% and 48. 61% , respectively, when the spore suspension was sprayed on the larvae. The immersing method also appeared to bring about the highest cadaver rates at 67. 50% for JYBb201 and 57. 50% for JYBb202. It was the same when the LT50 values were used for the comparison 3. 510 d for JYBb201 and 3. 808 d for JYBb202.关键词
