摘要

摘要研究了幼虫取食对斑蝶生活史性状的影响(林奈，1758)(鳞翅目:蝶科)生活史变化与食物可得性的关系。分别饲喂100、200、400、800、1600和3200mg /d的不同食物量饲养0日龄的黄腹棘腹虫幼虫，对照组采食量不限。发现幼虫的龄期和体重以及因此的适合度与可获得的食物量有关。在像印度加尔各答这样的城市地区，食物供应的差异可能会导致pyranthe生命史特征的变化，从而影响其适应性和存活率。

Food dependent changes of the life history traits of Catopsilia pyranthe (Lepidoptera: Pieridae)

ABSTRACT The effect of larval feeding on the life history traits of the mottled emigrant butterfly Catopsilia pyranthe (Linnaeus, 1758) (Lepidoptera: Pieridae) was assessed to link life history variations as a function of food availability. The 0-day-old larvae of C. pyranthe were reared with varying quantity of food (100, 200, 400, 800, 1600 and 3200 mg/day) against a control set with ad libitum food availability. Significant differences in instar duration and body weight of the larva and therefore fitness were found in relation to the amount of food available. In urban regions like Kolkata, India, disparity in food availability may induce variations in life history traits and thus fitness and survival in C. pyranthe.
