分别用薇甘菊MikaniamicranthaHBK、飞机草ChromolaenaodorataL.、革命菜GynuracrepidioidesBenth、菜心BrassicaparachinensisBailey和白菜BrassicachinensisL.饲养安婀珍蝶Actinoteanteas,计算各龄期试虫的存活率;测定不同食料植物对安婀珍蝶4龄幼虫的营养利用以及中肠中淀粉酶、海藻糖酶、蔗糖酶和羧酸酯酶活性的影响。结果表明薇甘菊饲养的试虫,其4、5、6龄的存活率高于其他供试食料植物上的试虫;取食薇甘菊的安婀珍蝶4龄幼虫相对生长率和食物利用率明显高于取食其他3种食料植物的试虫,但其相对取食量明显较低;取食薇甘菊的安婀珍蝶4龄试虫羧酸酯酶比活力明显高于以其他3种植物为食的试虫;取食白菜的4龄试虫,其蔗糖酶、海藻糖酶和淀粉酶比活力较低。这些研究结果表明安婀珍蝶对革命菜、菜心和白菜存在不同程度的取食利用障碍,由此判定他们不会成为安婀珍蝶的寄主植物。
The survival rate of pest insects at each instar was calculated by using Mikaniaamicrantha HBK, Chromolaenaodorata L., Gynuracrepidioides Benth, Brassicaparachinensis Bailey, and Brassicachinensis L. The survival rate of test insects at each age was calculated. Nutrient utilization and amylase, trehalase, invertase and carboxylesterase activities in the midgut. The results showed that the survival rate of 4,5 and 6 instar larvae of Mikania micrantha was higher than that of the other tested plants. The relative growth rate and food utilization rate of 4th instar larvae fed Mikania micrantha were significantly higher While feeding on the other three kinds of food plants test insects, but the relative edible was significantly lower; take Mikania micrantha the fourth instar insect carboxylesterase specific activity was significantly higher than the other three kinds of plant food Of the test insects; feeding cabbage 4th instar pest, sucrase, trehalase and amylase activity is lower. The results of these studies indicated that Apodemus species had different levels of feeding and utilization problems with the revolutionary vegetables, cabbage and cabbage. Therefore, they were not judged to be the host plants of the Apodemus giganteum.
