Hari C Sharma
"Hari C Sharma is a Principal Scientist–Entomology at the International Crops Research Institute for the semi-Arid Tropics (ICRISAT), Hyderabad, India. His contributions are in the areas of insect bio-ecology and use of host plant resistance and biotechnological approaches for IPM. He has authored over 250 research papers, 150 book chapters/conference papers, and five books. A Fellow of six Academic Societies, Dr Sharma has been conferred with several awards including Excellence in Science Award of the Consultative Group on International Agricultural Research (CGIAR), Plant Protection Award of Distinction by International Association of Plant protection Sciences (IAPPS), and Hari Om Trust Award by the Indian Council of Agricultural Research (ICAR). He is a Governing Board Member –IAPPS, and President - International Congress of Entomology. "
"Global warming and climate change will trigger major changes in diversity and abundance of arthropods, geographical distribution and population dynamics, herbivore plant interactions, activity and abundance of natural enemies, and efficacy of crop protection technologies for pest management. Changes in geographical distribution and population dynamics will affect both crop production and food security. Insect pests presently confined to tropical and subtropical regions will move to temperate regions along with a shift in the areas of production of their host plants, while distribution and relative abundance of some insect species vulnerable to high temperatures in the temperate regions may decrease as a result of global warming. These species may find suitable alternative habitats at greater latitudes. Many species may have their diapause strategies disrupted as the linkages between temperature, moisture regimes, and daylength will be altered. Genetic variation and multi-factor inheritance of innate recognition of environmental signals may mean that many insect species will have to adapt readily to such disruption. Host-plant resistance, bio-pesticides, natural enemies, and synthetic chemicals are some of the potential options for integrated pest management. However, the relative efficacy of many of these pest control measures is likely to change as a result of global warming. Therefore, there is a need to assess the efficacy of various pest management technologies under diverse environmental conditions, and develop appropriate strategies for pest management to mitigate the adverse effects of climate change.
