共生细菌和昆虫之间复杂的相互作用最终导致自然昆虫种群中生命各方面的平衡。本研究利用qPCR方法对1553个棉蚜个体的主要共生细菌丰度进行了估计。蚜虫的主要寄主植物是木槿和棉花。在4月、9月和11月从24个不同地点采集芙蓉蚜虫，而在2015年至2017年期间，在气候条件差异很大的地区采集棉花蚜虫。蚜虫占总蚜虫的30% ~ 45%，其中最占优势的共生体为Arsenophonus。其他共生体较少，约7%的蚜虫与哈密顿氏菌、不动杆菌和微杆菌共生，3%的蚜虫与沙雷氏菌和假单胞菌共生。蚜虫感染汉密尔顿氏菌、Arsenophonus和沙雷氏菌可影响布氏菌密度。汉氏菌与Arsenophonus和Serratia的密度有正交互作用。新乡蚜虫中hamtonella和Arsenophonus的合并感染率接近100%，华北蚜虫中合并感染率为50%，海南蚜虫中未发现合并感染。这些发现描述了棉蚜自然种群中共生细菌核心群落的流行模式和丰富度，为共生细菌的研究提供了新的思路。蚜虫感染Arsenophonus和Hamiltonella的比例分别为30% ~ 45%和10%。蚜虫感染了哈密顿氏菌、Arsenophonus和Serratia，对布氏菌的密度有不同的影响。寄主植物可能比生物型对细菌共生体感染频率和密度起重要作用。
Complex interactions between symbiotic bacteria and insects ultimately result in equilibrium in all aspects of life in natural insect populations. In this study, abundance of principal symbiotic bacteria was estimated using qPCR in 1553 individuals of aphids, Aphis gossypii. Aphids were sampled from primary and secondary host plants—hibiscus and cotton. Hibiscus aphids were collected from 24 different locations in April, September, and November, whereas cotton aphids were collected between 2015 and 2017 from areas with wide variations in climatic conditions. About 30%–45% aphids were recorded with the most dominant symbiont, Arsenophonus. The other symbionts were in low frequency, and about 7% of aphids were noted with Hamiltonella, Acinetobacter, and Microbacterium, and 3% of aphids were verified with Serratia and Pseudomonas. Aphids infected with Hamiltonella, Arsenophonus, and Serratia can influence Buchnera densities. Hamiltonella has positive interaction with densities of Arsenophonus and Serratia. Almost 100% coinfection of Hamiltonella and Arsenophonus was detected in Xinxiang aphids and 50% coinfection was reported in aphids from North China, while no coinfection was detected in Hainan aphids. These findings describe the prevalence pattern and richness of core community of symbiotic bacteria in naturally occurring populations of A. gossypii and provide new insights for the study of symbiotic bacteria. About 30%–45% and 10% aphids were found infected with Arsenophonus and Hamiltonella, respectively. Aphids infected with Hamiltonella, Arsenophonus, and Serratia can influence Buchnera densities with different variations. Host plant may play important role than biotypes on bacterial symbiont infection frequencies and densities.
