The insecticidal potential of cells and acid-precipitated biomolecules (APB) of (Roberts) (Bacillales: Bacillaceae) R2 was evaluated against polyphagous pest . The intact cells of isolate R2 and its APB preparation significantly increased larval mortality. Both cells and APB significantly delayed the development and reduced adult emergence of . The toxicity of isolate R2 was evident from the emergence of morphologically deformed adults with crumpled and underdeveloped wings. The nutritional physiology of larvae fed on APB-supplemented diet was also adversely affected resulting in significant reduction of relative growth and consumption rate as well as efficiency of conversion of ingested and digested food. Thus, the intact viable cells and APB of R2 may serve as environmental-friendly alternatives to chemical insecticides.
评估了苏云金芽孢杆菌（Roberts）（芽孢杆菌目：芽孢杆菌科）R2的细胞和酸沉淀生物分子（APB）对多食性害虫小菜蛾的杀虫潜力。分离株R2的完整细胞及其APB制剂显著提高了幼虫死亡率。细胞和APB均显著延迟了小菜蛾的发育并减少了成虫羽化。分离株R2的毒性从形态变形的成虫出现可见，其翅膀皱缩且发育不全。取食添加APB饲料的幼虫的营养生理学也受到不利影响，导致相对生长率、取食率以及摄入和消化食物的转化率显著降低。因此，苏云金芽孢杆菌R2的完整活细胞和APB可作为化学杀虫剂的环保替代品。
