摘要
通过增加显花植物的种类和显花时间来补充天敌的非猎物性营养源,以提高天敌的自然控害作用。研究了取食不同植物花后黑肩绿盲蝽后代(F1代)生长和捕食能力的变化。结果表明,黑肩绿盲蝽在取食盛花期的长柄菊、一点红、万寿菊和芝麻花后,其F1代雌若虫历期显著缩短;F1代4龄若虫及雌成虫对褐飞虱的捕食量显著提高。取食芝麻花、万寿菊后,其F1代黑肩绿盲蝽4龄若虫对褐飞虱卵的捕食能力分别比对照提高了140.8%、79.0%,取食万寿菊后,对褐飞虱雌成虫的捕食能力提高了35.2%。
It has been widely recognized that natural enemy control capacity could be improved strongly by increasing the kinds of flowering plants and flowering time to supple non-prey sources for natural enemies. This study explored the nymph growth and predatory capacity of mired bug Cyrtorhinus lividipennis offspring after feeding the parental adults with different plant flowers. The results showed that the nymph duration of female offspring had been significantly reduced and the predation of the offspring the 4th instar nymphs and female adult were evidently improved after feeding the parental adults with Tagetes erecta, Trida procumbens, Emilia sonchifolia and Sesamum indicum flowers. The prefatory capacity to planthopper eggs of 4th instar nymphs those fed parental adult with sesame flowers significantly increased by 140.8% compared to the check treatment, followed by marigold increasing by 79.0%, and the marigold could markedly increase preda- tion of female adults by 35.2%.
