摘 要 ：四株表达苏云金杆菌δ-内毒素蛋白基因的大肠杆菌对林业主要害虫杨扇舟蛾Clostera anachoreta(Fabricius),马尾松毛虫Dendrolimus punctatus(Walker),舞毒蛾Lymantria dispar(Linnaeus),杨尺蠖Apocheima cinerarius(Erschoff)幼虫作用进行了室内生物测定,结果表明:该四株菌对上述四种昆虫幼虫均表现出较高的杀虫活性,而且能显著抑制昆虫幼虫的生长发育。

Abstract:Bioassay of four Escherichia coli of experessing Bacillus thuringiensis δ-endotoxin gene against forest pests (Lymantria dispar, Apocheimacinerarius, Dendrolimus punctatus, Clostera anachoreta) showed: The four cloned strains had high toxicity against above-mentioned pests and could inhibit growth and development of the pests.
