 ABSTRACT

The climate change and global warming have affected the rice insect pests scenario drastically. The impact of climate change on agriculture will be one of the major deciding factors influencing the future food security of the mankind. Rice is one of the most important staple food of the world as well as India. The duration of insect life cycle is altered under increased temperature, elevated carbon dioxide concentrations and decreased precipitation. An increase of 0.4ºC average surface temperature over past century in India11 has led to rice insect pests losses increase from 10% during the pre green revolution period to 25% during the post green revolution period5. The rice plant hoppers (Nilaparvata lugens and Sogatella furcifera) in rice have reported recent outbreaks in relation to climate change in India15. The climate change has affected number of major insect pests of rice have increased from 3 to 15 (500 times) since 1965 to 2009 in India8. Meanwhile, the rice stem borers (Scirpophaga incertulas and Chilo suppressalis) and rice leaf folder (Cnaphalocrocis medinalis) have been maintaining the major insect pests status8. In eastern Uttar Pradesh, the rice hispa, rice cutworm, common termite, rice earhead bug, rice grasshopper and green leaf hoppers were not considered as serious insect pests till 2005, now assumed major insect pests status8,10. The changes in rice insect pests losses low to severe has been inference with impact of climate change on rice insect pests under eastern Uttar Pradesh conditions, while increase of 0.7º C to 1º C average surface temperature and rainfall decrease to 737 mm by 20116,13. This paper attempts to analyse the review of impact of climate change on rice insect pests under eastern Uttar Pradesh conditions to reduce the risk of strategy for effective rice insect pest management.

Key words: Climate change, Rice insect pests, Eastern Uttar Pradesh, India.
