红珠凤蝶小斑亚种幼虫的生物学特性

Bionomics of the Larvae of the Pachliopta aristolochiae adieus

为合理开发利用红珠凤蝶小斑亚种和有效控制其为害。室内用卵叶马兜铃叶片饲养幼虫,研究了红珠凤蝶小斑亚种幼虫的生活习性、取食量和体重的变化规律。结果表明,幼虫有取食自身蜕和相互残杀的习性。1~3龄幼虫取食量较小,为幼虫总食量的5.23%,5龄幼虫的取食量最大,为幼虫总食量的77.11%。取食速率的变化趋势与取食量相似。幼虫期体重变化呈＂S＂型。

To utilize and effectively control Pachliopta aristolochiae adaeus, the life habit, food amount and body weight of Pachliopta aristolochiae adaeus larva being fed on leavies of Aristolochiae tagala were studied in the laboratory. The results showed that larvae had the habit of feeding on their own sloughs and killing each other. Food amount of the 1stto 3rd instars was smaller, accounted for 5.23% of the total food amount, while that of the 5th instars was the biggest, accounted for 77.11%. The trend of the feeding rate was similar to that of the feeding amount. The changes of body weight showed S-type in the larval stage.
