蟑螂是城乡家庭中最常见的害虫,也是地球上繁殖力最强的昆虫之一。尽管每年使用大量神经毒素杀虫剂来消灭蟑螂,但第二年会出现更多的蟑螂。美国康奈尔大学昆虫学家杰弗里·斯科特及其学生正在研究一种有效的、无毒性的灭蟑螂新方法。他们克隆了德国蟑螂的5个P450基因,包括一个CYP6L1基因,这些基因对雄性蟑螂的生殖腺具有明显的但至今仍是神秘的作用。科学家说,最终控制蟑螂繁殖的 Cockroaches are the most common pests in urban and rural areas and one of the most fertile insects on Earth. Although a large number of neurotoxin insecticides are used to eradicate cockroaches each year, more cockroaches occur in the second year. Jeffrey Scott, an entomologist at Cornell University in the United States, and his students are studying an effective, nontoxic new way to kill cockroaches. They cloned the five P450 genes from German cockroaches, including one of the CYP6L1 genes, which have obvious but still mysterious effects on the gonads of male cockroaches. Scientists say eventually control cockroach breeding
