以白僵菌孢子和提取毒素感染亚洲玉米螟Ostrinta furnacalis幼虫,引起血淋巴蛋白质含量降低,蛋白质凝胶电泳区带减少。无论是孢子感染或经饲喂和注入虫体毒素,试虫血淋巴中皆有不受毒作用影响的稳定性蛋白质存在。还可看出,培养液提取毒素对试虫血淋巴蛋白质的影响大于由菌粉提取的毒素。此外证实了提取毒素经贮存7年仍有毒效。 Infection with Ostrinia furnacalis larvae caused by Beauveria bassiana spores and extract toxins resulted in a reduction of haemolymph protein content and reduction of protein gel electrophoresis bands. Whether sporozoite infection or feeding and injection of parasites toxins, insects hemolymph are not affected by the toxic effects of the existence of stable proteins. It can also be seen that the extraction of toxins from the culture medium exerts a greater influence on hemolymph proteins of the test insects than the toxins extracted from the bacterial strains. In addition, it was confirmed that the extraction of toxins is still toxic after being stored for seven years.
