The mortality of the Alabama argillacea and Chrysodeixis includens (Lepidoptera: Noctuidae) larvae caused by the kaolin inert powder and the entomopathogenic fungus Beauveria bassiana were determined under laboratory conditions. Using the caterpillar submersion method, the CG 138 B. bassiana isolate was more pathogenic to A. argillacea than the CG 70, GC 82, ESALQ 634, and ESALQ 645. All five tested isolates caused similar mortality of C. includens. The mortality of first-instar larvae of A. argillacea and C. includens by feeding on leaf-disc impregnated with B. bassiana (CG 138) and kaolin was also determined. Higher A. argillacea mortalities were observed in the B. bassiana (CG 138) treatments, regardless of the presence of kaolin. However, the activity of kaolin + B. bassiana (CG 138) against C. includens was higher than each ingredient alone, indicating an additive action against C. includes larvae. The mortality of A. argillacea and C. includens larvae treated with kaolin + B. bassiana (CG 138) was similar, and the A. argillacea mortality was higher than that of C. includens with kaolin and B. bassiana (GC 138) separated. The treatment kaolin + B. bassiana (CG 138) is promising for the simultaneous management of these two defoliator pests, mainly A. includes. In addition, the monophagous A. argillacea is more susceptible to both kaolin and B. bassiana (GC 138) than the polyphagous C. includens, suggesting that the nutritional ecology plays an important role in the susceptibility of these defoliator species to alternative insecticides.

阿拉巴马州argillacea和Chrysodeixis包括（鳞翅目：夜蛾科）幼虫对白僵菌与高岭土的敏感性

在实验室条件下，测定了由高岭土惰性粉末和昆虫致病性球孢白僵菌引起的阿拉巴马州灵芝和金孢子虫（鳞翅目：夜蛾科）幼虫的死亡率。使用卡特彼勒浸没法，与CG 70，GC 82，ESALQ 634和ESALQ 645相比，CG 138球孢白僵菌菌株对曲霉的致病性更高。所有五个测试菌株均导致相似的C. includens死亡率。还通过饲喂浸有球芽孢杆菌（B. bassiana）（CG 138）和高岭土的叶盘，确定了紫精曲霉和隐孢子虫的第一龄幼虫的死亡率。不论是否存在高岭土，在球孢杆菌（B. bassiana）（CG 138）处理中均观察到较高的曲霉死亡率。但是，高岭土+球孢白僵菌（CG 138）对C. includens的活性高于单独的每种成分，表示对幼虫的累加作用包括幼虫。高岭土+球茎毕赤酵母（CG 138）处理的紫茎泽兰和隐孢子虫的死亡率相近，且分离的高岭土和球茎毕赤酵母的孢子菌的死亡率较高。 。高岭土+球孢杆菌（CG 138）有望同时处理这两种落叶落叶害虫，主要包括A.。此外，单相食性曲霉菌比多食性隐孢子虫更容易受到高岭土和球孢杆菌（GC 138）的影响，这表明营养生态学在这些落叶者对其他杀虫剂的敏感性中起着重要作用。球藻（CG 138）相似，并且紫花曲霉的死亡率高于高岭土和球孢杆菌（GC 138）分离的隐孢子虫的死亡率。高岭土+球孢杆菌（CG 138）有望同时处理这两种落叶落叶害虫，主要包括A.。此外，单相食性曲霉菌比多食性隐孢子虫更容易受到高岭土和球孢杆菌（GC 138）的影响，这表明营养生态学在这些落叶者对其他杀虫剂的敏感性中起着重要作用。球茎贝司（CG 138）相似，且高岭土和球茎贝司（B. bassiana）（GC 138）分开的紫花曲霉死亡率高于隐孢子虫。高岭土+球孢杆菌（CG 138）有望同时处理这两种落叶落叶害虫，主要包括A.。此外，单相食性曲霉菌比多食性隐孢子虫更容易受到高岭土和球孢杆菌（GC 138）的影响，这表明营养生态学在这些落叶者对其他杀虫剂的敏感性中起着重要作用。
