英国国际生物防治研究所,从蝗虫的天敌体中分离出 Beau veria 和 Metorhizium 两种真菌,用这两种真菌原体培育出的孢子液剂,对蝗虫的杀灭效果极好。该制剂已用在蝗虫发生地带进行喷洒防治,喷药10天后蝗虫的死亡率高达96.8％。这种真菌孢子液在常温贮藏下的活性,可保持8年左右,因而可以储藏,以备发生蝗虫时急用。这种孢子液对其他生物无毒害和副作用,是目前最理想的灭蝗剂。 British Institute for International Biological Prevention, from the natural enemies of locusts isolated two kinds of fungi Beau veria and Metorhizium, with these two kinds of fungal spore agents to cultivate spores, killing locusts very well. The preparation has been used in the locust control zone spray spraying, grasshoppers 10 days after the death rate as high as 96.8%. The activity of this fungal spore liquid stored at room temperature, can be maintained for about 8 years, which can be stored for emergency use in case of locusts. This spore liquid non-toxic to other organisms and side effects, is currently the best off locust agent.
