| 摘 要： | 分别用薇甘菊Mikania micrantha HBK、飞机草Chromolaena odorata L.、革命菜Gynura crepidioides Benth、菜心Brassica parachinensis Bailey和白菜Brassica chinensis L.饲养安婀珍蝶Actinote anteas，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。

| Abstract: | The effects of feeding on different food plants, Mikania micrantha HBK, Chromolaena odorata L., Gynura crepidioides Benth, Brassica parachinensis Bailey and Brassica chinensis L., on the survival rate and nutritional utilization of the larvae of Actinote anteas were investigated. The impact of feeding on different food plants on the activity of amylase, trehalase, sucrase and esterase in the midgut of the 4th instar larvae were assayed in vitro. The results showed that the survival rate of 4th, 5th, 6th instar larvae fed on the M. micrantha are higher than that of those fed on the other three food plants. Although the relative consumption rate of 4th instar larvae fed on M. micrantha was low, the relative growth rate and the efficiency conversion of ingested food of these larvae were markedly higher than that of those on the other three plants (P<0.05). Furthermore, significant high enzyme activity of esterase was found in 4th instar larvae of A. anteas that fed on M. micrantha. The enzyme activities of amylase, sucrase and trehalase of A. anteas fed on B. chinensis were relatively low. The results indicated that the larvae of A. anteas had lower capability to utilize G. crepidioides, B. parachinensis and B. chinensis, and this suggested that these three species of plants would not become the host plants of A. anteas. |
