Abstract

Toxicity of Bacillus thuringiensis spores to the tobacco hornworm, Manduca sexta, is described. The numbers of larvae killed were in relation to spore dry weight. At a surface application of 6.8 ng/cm2, there was an 85 percent survival, but less than 50 percent survived at 68.2 ng/cm2. Striking similarity of spores to parasporal crystals is revealed by slope of mortality curves, inhibition of stadial growth, and 50 percent lethal dose values based on protein content.

摘要

描述了苏云金芽孢杆菌孢子对烟草天蛾(Manduca sexta)的毒性。幼虫死亡数量与孢子干重有关。表面施用量为6.8纳克/平方厘米时,存活率为85%,但在68.2纳克/平方厘米时,存活率不到50%。死亡率曲线斜率、龄期生长抑制以及基于蛋白质含量的半数致死剂量值显示,孢子与伴孢晶体具有惊人的相似性。
