Food dependent changes in the life history traits of <i>Catopsilia pyranthe</i> (Lepidoptera: Pieridae)

The effect of larval feeding on the life history traits of the mottled emigrant butterfly <i>Catopsilia pyranthe</i> (Linnaeus, 1758) (Lepidoptera: Pieridae) was assessed to link life history variations as a function of food availability. The 0-day-old larvae of <i>C. pyranthe</i> were reared with varying quantity of food (100, 200, 400, 800, 1600 and 3200 mg/day) against a control set with <i>ad libitum</i> 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 <i>C. pyranthe</i>.

本研究评估了幼虫取食对云斑迁粉蝶（mottled emigrant butterfly，<i>Catopsilia pyranthe</i>，Linnaeus, 1758，鳞翅目：粉蝶科）生活史性状的影响，旨在建立生活史变异与食物可获得性之间的关联。本实验以0日龄云斑迁粉蝶幼虫为试材，设置梯度食物供应量（100、200、400、800、1600及3200 mg/天）进行饲养，并以自由取食（ad libitum）组作为对照。结果显示，幼虫龄期时长、体质量及由此决定的种群适合度，均随食物供应量的变化呈现显著差异。在印度加尔各答等城市区域，食物可获得性的差异可能诱导云斑迁粉蝶的生活史性状产生变异，进而影响其种群适合度与生存能力。
