Abstract

This paper presents comparative assessment of the reaction of the western flower thrips Frankliniella occidentalis and the predatory bug Orius laevigatus to the seed oil of Pongamia pinnata (L.) Pierre. This oil had repellent and toxic effects on the adult and larval thrips, and also reduced the number of laid eggs. The predatory bug O. laevigatus was highly sensitive to P. pinnata oil under various methods of exposure, even at a concentration of 0.75%, which was the lowest concentration effective against the thrips. The observed side effects of the oil on O. laevigatus determine the need either for development of a specific approach for combined use of the oil and this entomophage, or for replacing O. laevigatus with some other predator resistant to P. pinnata oil.

西方花蓟马Frankliniella occidentalis Perg反应的比较评估。（Thysanoptera，Thripidae）和掠食性Bug Orius laevigatus Fieber（Heteroptera，Miridae）到Pongamia pinnata（L.）

摘要

本文介绍了西方花蓟马Frankliniella occidentalis和捕食性臭虫Orius laevigatus对Pongamia pinnata（L.）Pierre种子油的反应的比较评估。这种油对成虫和幼虫蓟马具有驱避和毒性作用，还减少了产卵的数量。在各种暴露方法下，捕食性臭OO。laevigatus对P. pinnata油都高度敏感，即使浓度为0.75％，这也是对抗蓟马的最低浓度。观察到的油对O. laevigatus的副作用确定是否需要开发一种将油和这种食虫动物联合使用的特定方法，或者需要用一些其他抗P.pinnata油的捕食者来替代O. laevigatus。
