浆角蚜小蜂防治温室白粉虱的应用研究

Studies on Eretmocerus Controlling Trialeurodes vaporariorum(westwood) on Cucumber in Greenhouse

温室白粉虱不仅取食植物造成直接危害,而且传播一些植物病毒病的病原。近年来,农民在温室中大量使用化学药剂来防治温室白粉虱,结果造成农药残留严重超标。本文采用生物防治的方法,对浆角蚜小蜂的应用技术和防治白粉虱的效果进行了研究与探讨。

The greenhouse whitefly is one of harmful insects of vegetable crops grown in greenhouse, which damaged not only by socking large quantities of sap from plant, but also serving as vectors of several economically important viral plant pathogens. Recently, farmers used a lot of pesticides to control greenhouse whitefly, which caused that the pesticide residue is larger than the normal standard. Techniques to release eretmocerus and its efficacy were studied. The results showed that the controlling effects of the parasite in a appropriate number were better when the whitefly population was lower on cucumber in greenhouse.
