已发现的细菌为枯草芽孢杆菌Cohn。(26 D)和苏云金芽孢杆菌(V-6066)和V-5689(菌株V-5689)能抑制麦长管蚜的活性。研究了所研究的芽孢杆菌的保护作用。菌株具有直接的杀虫活性，通过调节过氧化氢的产生、过氧化氢酶和过氧化氢酶的活性以及NADPH氧化酶、PR-6和PR-9等防御相关基因的表达，间接诱导小麦植株产生系统抗性。苏云金芽孢杆菌和枯草芽孢杆菌分别诱导茉莉酸依赖的信号通路和水杨酸依赖的信号通路基因。研究发现，所研究的芽孢杆菌属细菌的组成。菌株对小麦植株抗虫性具有加性效应。这些结果支持这些芽孢杆菌的使用。菌株作为进一步开发防治麦长管蚜的生物修复技术的基础。
It has been found that the bacteria Bacillus subtilis Cohn. (strain 26 D) and Bacillus thuringiensis Berliner (strains V-6066 and V-5689) are able to suppress the vital activity of the greenbug aphid Schizaphis graminum Rond. The protective effects of the studied Bacillus spp. strains consisted of direct aphicidal activity, and they indirectly induce systemic resistance in wheat plants via the regulation of hydrogen peroxide generation, the activity of peroxidase and catalase, and an increased expression of defense-related genes, such us NADPH oxidases, PR-6, and PR-9. It has been shown that B. thuringiensis strains induced genes of the jasmonate-dependent signaling pathway, and B. subtilis strain induced genes of the salicylate-dependent signaling pathway. It has been found that the composition of the studied Bacillus spp. strains had an additive effect of wheat plant resistance to pests. These results support the use of these Bacillus spp. strains as a basis for the further development of a biopreparation against cereal aphids.
