Impact of individual climate change parameters on insect pests and crop yield has been the primary focus of some previous studies. The goal of this study is to find the effects elevated levels of CO2 (EC), ozone (EO), and the interaction between temperature and CO2 (ET+EC) on the Brown Plant Hopper (BPH), Nilaparvata lugens, in rice. The biological traits of BPH, such as an accelerated sap sucking rate, decreased development time, and increased population rate, significantly increased under EC and ET+EC compared to ambient conditions; however, the population of BPH was lower in ET+EC compared to EC. BPH infestation reduced yields of crop by 15.9% (under EC) and 11.5% (under ET+EC) compared to the uninfested crop, despite its significant positive impact on plant growth and yield attributes. In contrast, biological traits of BPH such as multiplication rate, abundance, and honeydew excretion were considerably decreased under EO conditions. It also had deleterious impact on rice growth and reproduction, particularly when combined with BPH infestation. The findings of this study indicate that pests and host plants benefited under EC and ET+EC conditions; however, increasing BPH populations caused yield losses. Nevertheless, EO had a detrimental effect on pests as well as host plants. The results pertaining to the collective impact of climate change factors on both the host plant and pests have the potential to contribute to the advancement of insect pest management strategies in response to shifting climates.
