    Effect of HBF-1 Strain of Bacillus thuringiensis on Growth and Development and Feeding of Anomala corpulenta and A.exoleta larvae

    • The effect of HBF-1 strain on survival rate, antifeeding, inhibition of growth and feeding behavior on 10 days instar larvae of Anomala corpulenta and A.exoleta larvae were studied by biological tests. The results showed that the survival rate of A. corpulenta larvae and A.exoleta larvae was decreased, the antifeeding effect and growth inhibition of A. corpulenta larvae were increased, the feeding selectitity to feedstuff of A.corpulenta larvae enhanced as the concentration of HBF - 1 strain was increased and the time of infected with HBF-1 strain was prolonged. The A. exoleta larvae LC50 作者简介: 宋健(1980-), 女, 河北涿州人, 实习研究员; * 通讯作者: 冯书亮(1957-),男, 河北威县人, 研究员, 主要从事杀虫微生物研究. 联系电话: 0312-5915680; E-mail: sj3250@163.com 基金项目: 河北省自然科学基金项目资助(C2005000642). was 64.16 μg/g for 7 d and decreased 13.98 μg/g for 14 d infected by HBF-1 strain.The A.exoleta larvae LC50 reduced from 79.69 μg/g to 19.14 μg/g treated with HBF-1 strain. When the A. corpulenta larvae treated with HBF-1 strain at the concentration of 10 μg/g soil for 7 d, the antifeeding rate and growth inhibition rate were 4.74% and 9.84%,30.75% and 73.87% for 14 d. When the A. corpulenta larvae treated with HBF-1 strain at the concentration of 160 μg/g soil for 7 d, the antifeeding rate and growth inhibition rate were 39.01% and 83.61%, 86.10% and 97.75% for 14 d. A.corpulenta larvae were somewhat repellent to the feedstuff containing HBF-1 strain of high concentration.
