The greenhouse gas carbon dioxide is increasing average temperature of the earth. Thus, the warmer, higher carbon dioxide world has affected the ecosystem. In addition, the ongoing Amazon rainforest fire may accelerate the global warming. However, how climate change affecting on plant-insect interaction is still poor understood and controversial. Furthermore, whether insect resistant crop will still keep the traits under climate change is also unknown. In addition, nowadays, it has a big need on good practice of integrated pest management in organic farming system. Thus, it is necessary and imperative to know the effect of climate change on insect resistant trait. Rice (Oryza sativa L.) is one of the most important food crops in the world and is used as a primary source of calories for more than one-third of the human population. However, a number of abiotic and biotic stresses pose significant challenges to efficient, high-quality production. Brown planthopper (Nilaparvata lugens Stål; BPH) is the most destructive insect pest of rice in Asia. BPHs cause direct damage by sucking phloem sap and further cause plant dead symptom called “hooper burn”. During feeding, BPHs could transmit grassy stunt virus (RGSV) and ragged stunt virus (RRSV). BPH caused devastating damages in rice production in Asia, including India, Vietnam, Taiwan, China, and Japan. Furthermore, BPH is a migratory pest which can migrate from South-Asia to Taiwan, Korea and Japan every year. In this project, we have tested a series of rice near-isogenic lines (NILs) carrying with BPH-resistant genes from International Rice Research Institute under climate change to understand BPH virulence on these BPH-NILs. In addition, the growth parameters of BPH on these BPH-NILs will be measured. Besides, the volatile organic compounds pattern of these BPH-NILs will be further analyzed to understand the antixenosis effect. The expected result of this proposal would help plant breeders for future breeding purpose on BPH resistant and also use for integrated pest management in the future.climate change, brown planthopper, resistant genes, near-isogenic lines, volatile organic compounds
