病原体Pathogen
据Science报道,这次的蝗灾蔓延到非洲国家索马里之后,当地会用到真菌来防治蝗虫。在生物防治的办法中,真菌属于病原体防治的一种。
Somalia, one of several African nations being hit hard by enormous swarms of locusts, is planning to control them with a fungus in what would be the largest use of biopesticides against these insects.
索马里是几个遭受蝗虫袭击的非洲国家之一,该国正计划用一种真菌来控制蝗虫,这将是杀灭害虫的生物杀虫剂规模最大的一次使用。
“Large-scale use to control an invasion of desert locusts would be a first,” says Michel Lecoq, a retired entomologist who worked on locust control at the French Agricultural Research Center for International Development. “If successful, it will be a big step forward.”
法国国际发展农业研究中心从事蝗虫防治工作的退休昆虫学家米歇尔·莱科克表示:“这是第一次大规模使用生物杀虫剂来控制沙漠蝗虫入侵。如果成功了,那么这将是向前迈出的一大进步。”
Young locusts, such as these (pictured) in northern Somalia, will be killed by a nontoxic biocontrol fungus before they swarm. (The biopesticides) consist of spores of the fungus Metarhizium acridum, which produces a toxin that kills only locusts and related grasshoppers.
索马里北部的幼蝗(如上图所示)在成群聚集之前就会被一种无毒的生物防治真菌杀死。(该生物杀虫剂)由真菌(Metrahizium acridum)的孢子组成,该真菌产生的毒素只会杀死蝗虫和相关的蝗虫。
