Recently, the Insect Pest Control and Biosafety Innovation Team of the Cotton Research Institute of the Chinese Academy of Agricultural Sciences analyzed the composition and changes of the cotton aphid-Cotton aphids microbe Adapt and adjust the host environment by sharing or changing host symbiotic bacteria. This research is of great significance for revealing the co-evolution of symbiotic bacteria-parasitic wasps-host insects, formulating new control strategies for cotton aphids, and carrying out biological control. Related research results were published in”Pest Management Science (Pest Management Science)”.
According to the team’s chief researcher Cui Jinjie, cotton aphid is a common pest widely distributed in various countries around the world, which can cause cotton leaves to turn yellow, shrink and grow slowly. Even the plant died. Parasitic wasps are important parasitic natural enemies of cotton aphids in North China cotton fields. The parasitic rate in the field can reach 80%. In view of the increasingly serious damage of cotton aphids, outbreaks and disasters, and enhanced resistance, we will study how parasitic wasps affect the changes in cotton aphid microbial communities. Their mutual relationship is of great significance to the control of cotton aphids. This study systematically explained the influence of parasitic wasps on the composition and structure of the symbiotic bacteria of cotton aphid by analyzing the composition and structure of the parasitic wasp-Cotton aphid symbiotic bacteria and the changes in the composition and abundance of the host-cotton aphid symbiotic bacteria during different periods of parasitism. The results of the study indicate that symbiotic microorganisms may be the potential driving force for the co-evolution of the complex and multi-layered metabolite and nutrient network between cotton aphid and cotton aphid. The research results have important theoretical and practical value for revealing the co-evolution of parasitic wasps and host insects, and for developing new cotton aphid prevention and control technologies.
The research was funded by the National Natural Science Foundation of China and the Science and Technology Innovation Project of the Chinese Academy of Agricultural Sciences.
