摘要:

为探究烟盲蝽(Nesidiocoris tenuis)对不同蔬菜害虫的控害潜能,本文在室内条件下测试了烟盲蝽对3种蔬菜害虫烟粉虱(Bemisia tabaci)、桃蚜(Myzus persicae)和小菜蛾(Plutella xylostella)的捕食量与捕食偏好性。非选择性试验结果表明,烟盲蝽雄成虫对烟粉虱成虫、桃蚜1~2龄若虫和小菜蛾2龄幼虫的捕食量分别为15.6、11.2和13.2头,对烟粉虱的捕食量最大,显著高于另外2种昆虫。在捕食偏好选择性试验中,烟盲蝽偏好捕食烟粉虱成虫,其次是小菜蛾2龄幼虫,对桃蚜1~2龄若虫的捕食性最少。此结果表明,对3种常见害虫,烟盲蝽对烟粉虱的控害潜力优于对其他2种害虫。

Abstract:

To explore the control potential of the mirid bug Nesidiocoris tenuis in vegetable pest management, the predation and preference of N. tenuis to three vegetable insect pests were tested via non-choice and choice experiments in the laboratory. The non-choice experiments showed that the predation of N. tenuis male adults on Bemisia tabaci adults, 1st-2nd instar nymphs of Myzus persicae and 2nd instar larvae of Plutella xylostella were 15.6,11.2 and 13.2, respectively. The highest predation was found on B. tabaci, which was significantly higher than the others. In choice experiments, N. tenuis preferred to feed on B. tabaci adults, followed by the 2nd instar larvae of P. xylostella and 1st-2nd instar nymphs of M. persicae. The results showed that for the three common pests in vegetable, N. tenuis could be preferentially used for the biological control of B. tabaci.

Key words: Nesidiocoris tenuis, Bemisia tabaci, Myzus persicae, Plutella xylostella, predation preference
