Abstract:

There are a wide range of nutritional symbiosis between symbiotic bacteria and insect hosts. Insect hosts provide nutrition and energy sources to symbiotic bacteria,and symbiotic bacteria can provide essential nutrients to insects,help insects digest food,and participate in nitrogen cycle and maintain normal physiological environment of insect hosts. The shared metabolic pathways between certain symbiotic bacteria and insect hosts provide impetus for host-symbiont coevolution. To provide deep insight into the cross-feeding between symbiotic bacteria and hosts,this paper reviewed nutritional function of symbiotic bacteria on insect hosts,the transshipment mode of nutrients between symbiotic bacteria and insects,and the regulation of insects on the production and transshipment of nutrients from symbiotic bacteria.

Key words: insect, symbiotic microorganism, nutrition, co-metabolism, transshipment of nutrients, compensatory adaptation
