| 摘 要： | 在实验室条件下测定腐胺处理对小菜蛾Plutella xylostella (L.) 3龄幼虫取食量、存活、羽化率、蛹重及保护酶活力的影响。结果表明,腐胺对小菜蛾幼虫的取食量、存活、羽化及保护酶活力均有明显的影响。经过腐胺处理后,3龄幼虫的取食量、存活率、化蛹率及体内SOD和POD活力均明显高于蒸馏水对照;但腐胺对其蛹重、蛹的羽化率及体内CAT活力却无明显的影响。

| Abstract: | The effects of putrecine on the feeding,survival and the activities of protective enzymes of diamondback moth Plutella xylostella(L.) larva were studied.The result showed that the consumed leaf area,the survival rate,the pupation rate and the activities of SOD and POD of the diamondback moth were significantly higher than those of the controls.While there was no significantly difference in pupa weight,eclosion rate,the activities of CAT between two groups. |
