在温室中可调节控制温湿度,因此有利于赤座霉菌对温室白粉虱的寄生。黄瓜的栽培条件给赤座霉菌的发育以特别有利的小气候。在黄瓜上我们用从印度、古巴、越南、中国和岛引入的10种赤座霉菌的类型进行了防治温室白粉虱的试验。在温室应用赤座霉菌的试验表明,赤座霉菌可引起粉虱若虫死亡72～98%,可抑制粉虱数量在经济为害水平以下。但是,只有将悬浮菌液细微均匀地喷到叶子背面时,才可能获得达样的效果。而在生产条件下,很难将菌液均匀周密地喷到叶子背面上,如果不能做到达一点,粉虱数量就要迅速恢复,因而还必须配合应用杀虫剂来消灭粉虱成虫。
In the greenhouse can be adjusted to control the temperature and humidity, it is conducive to Hollocarpa on greenhouse whitefly parasitic. The cucumber cultivation conditions give a particularly favorable microclimate to the development of Pediococcus. On the cucumber we tested the control of B. tabaci with 10 species of Hollocchi, introduced from India, Cuba, Vietnam, China and the island. Tests on the application of Clostridium molds in greenhouses show that Clostridium jejuni can cause 72-98% mortality of whitefly nymphs and inhibit the population of whiteflies below economically harmful levels. However, it is only possible to achieve a sample-like effect by spraying the suspension liquid finely and uniformly to the back of the leaves. In the production conditions, it is difficult to spray the bacteria evenly and evenly on the back of the leaves, if you can not do that, the number of whiteflies will quickly recover, and therefore must also cooperate with the application of insecticides to eliminate whitefly adults.
