Abstract：As the development of the industrialization process, the atmospheric concentration of CO2 increased year by year. Studies have shown that the concentration of CO2 in the atmosphere in the 2050s will be likely to double, so it is necessary to study the effects of elevated CO2 concentrations on plants and even herbivorous insects. In China, brown planthopper is a very important rice pest, with a sucking mouthparts, great harm to rice. In this paper, the effects of CO2 enrichment on the suitability and feeding behavior of brown planthopper were mainly discussed. The main reasons: CO2 doubling significantly reduced the egg stage, nymph duration and female life of brown planthopper, and significantly reduced the weight of female feathers. The duration of P wave duration and the duration of N5 wave in the xylem were not significantly affected, but the effect of the doubled CO2 concentration on the growth and longevity of the larvae was not significantly affected. The duration of the N4a wave has no significant effect on the duration of the N4b wave and the N7 wave. The doubling of CO2 concentration can significantly shorten the developmental period of brown planthopper and increase the damage algebra. However, at the cost, the weight of the brown planthopper is reduced, which may be caused by the increase of the P wave. The results showed that rice could face the risk of increasing the damage of rice brown planthopper in the future atmosphere.
