| 摘 要： | 分别用马尾松、雪松、火炬松、湿地松和黑松饲养松墨天牛,研究不同寄主植物对松墨天牛补充营养期的营养效应以及对体内酯酶与羧酸酯酶活性的影响.结果表明:不同寄主植物对补充营养期松墨天牛的营养效应、酯酶与羧酸酯酶的活性有显著影响.用马尾松和雪松饲养的试虫,羽化后第5天体质量开始增加;其余3种树种饲养的试虫,至第7天体质量才开始增加.取食马尾松的松墨天牛雌、雄成虫,其相对取食量、相对代谢率和食物利用率均高于取食其他4种寄主植物的试虫;取食马尾松的松墨天牛雌、雄成虫体内酯酶和羧酸酯酶的活性也显著高于取食其他寄主的试虫;试验结果表明:马尾松是松墨天牛补充营养期的最适寄主. |

| Abstract: | In order to illustrate the effect of different plant hosts on nutrient function and activity of the esterase and carboxylesterase of Monochamus alternatus in the food-replenishing period,M.alternatus was fed respectively with Pinus massoniana,Cedrus deodara,P.teada,P.elliottii and P.thunbergii.The results showed that there were significant differences in the nutrient status,and activity of the esterase and carboxylesterase of the insect fed with the five different plants.The insects fed with P.massoniana or... |
