1985～1986年,在陕北宜川县云岩镇方圆10km~2内400余个野外洞穴和13～14个自然村进行溴氰菊酯杀灭近野栖中华白蛉方法的研究.两年喷洒总面积达74 000m~2。经喷洒野外洞穴和村内畜窑相结合的处理措施,1986年6和8月,野外对照洞穴的白蛉密度比1985年同期分别下降79.1％和46.9％,村内对照畜窑分别下降71.5％和59.6％.连续两年的喷洒实验结果表明,野外洞穴喷洒溴氰菊酯结合村内畜窑喷洒的方法是防治陕北黄土高原近野栖中华白蛉的有效方法。
From 1985 to 1986, the method of deltamethrin killing near-field habitat was studied in more than 400 wild caves and 13 ~ 14 natural villages within 10km ~ 2 of Yunyan Town, Yichuan County, northern Shaanxi Province. Area of 74 000m ~ 2. In June and August 1986, the whitefly density of the field control caves decreased by 79.1% and 46.9% over the same period of 1985 respectively, while that of the livestock kilns in the village decreased by 71.5% and 59.6% respectively The results of spraying experiments for two consecutive years show that the method of spray spraying deltamethrin in the field with the livestock kiln in the village is an effective method to control the near wild habitat of Chinese white fagace in the Loess Plateau of northern Shaanxi.
