目的比较在相同的环境条件下不同食料植物对东亚飞蝗肠道细菌状况的影响。方法以墨西哥玉米、野生马唐为食料植物饲喂东亚飞蝗,在其成虫肠道内和粪沙中分离纯化细菌,获得22株菌株,分别对其培养性状、菌体形态、染色反应和生理生化性状进行系统研究。结果上述22个菌株分别属于稀有杆菌属(Rarobact-er)、短状杆菌属(Brachybacterium)、棒杆菌属(Corynebacterium)、棍状菌属(Clavibacter)、葡萄球菌属(Staphylococ-cus)、丙酸杆菌属(Propionibacterium)、埃希菌属(Eschrichia)、气微杆菌属(Aercmicrobium)、沙雷菌属(Serratia)、克雷伯菌属(Klebsiella)、沙门菌属(Salmonella)、志贺菌属(Shigella)、口腔球菌属(Stomatococcus)、短杆菌属(Brevibacteri-um)、地杆菌属(Terrbacter)、微小杆菌属(Exiguobacterium)、皮杆菌属(Dermabacter)、短小杆菌属(Curtobacterium)、纤维单胞菌属(Cellulomonas)、微杆菌属(Microbacterium)、乳杆菌属(Lactobacillus)和凝结芽胞杆菌属(Bacilluscoag-ulans)。结论不同食料植物对东亚飞蝗肠道细菌种类和数量有很大的影响。
Objective To compare the effects of different food plants on the intestinal bacterial status of the migratory locusts in the same environmental conditions. Methods Mexican maize and wild crabgrass were fed on Locusta migratoria manilensis to separate and purify the bacteria in the gut and manure of their adult worms. Twenty-two strains were obtained. Their culture traits, cell morphology, staining reaction and physiological and biochemical Systematic research on traits. Results The above 22 strains belong to the genus Rarobact-er, Brachybacterium, Corynebacterium, Clavibacter, Staphylococ-cus, Propionibacterium, Eschrichia, Aercmicrobium, Serratia, Klebsiella, Salmonella, Shigella, Stomatococcus, Brevibacteri-um, Terrbacter, Exiguobacterium, Dermabacter, Curtobacterium, Cellulomonas, Microbacterium, Lactobacillus, and Bacillus coagulans. Conclusion Different kinds of food plants have a great influence on the types and quantity of intestinal bacteria in the migratory locusts.
