399 Proceedings of the Princess Maha Chakri Sirindhorn Congress The international researches were reviewed to show the example of the consequences of global warming that affects insects’ livelihood. We reviewed the published literatures that studied the impacts of global warming and climate change on insects and insect pests in general. This includes the impacts on physical, diversity, habitats and other related issues. 2. Results Climate change and crop pest management A review by Babasaheb et al. 2012 has showed that global warming and climate change effect the insect pest population diversity and abundance significantly. Thus, the patterns of the insect pest population dynamics have changed following those changes too. The impact to the insect pests at various aspects has led to the consequences of crop loss due to the outbreak of them that in the end it is timely to address the threat to lessen the damage. In the review, the authors has showed the impact of the insect pest spreading caused by the climate change to the India agriculture. The phenomena results in impacts on insect pest of agriculture importance on various aspects that includes: l Loss of ecological biodiversity l Expansion of geographic ranges l Increased overwintering survival l Increase in number of generations l Risk of introducing invasive alien species l Impact on pest population dynamics and outbreak l Breakdown of host plant resistance l Impact on crop-pest interactions l Increased incidence of insect vectored plant disease l Reduced effectiveness of biological control agents l Disruption of plant – pollinator interactions Consequence to the direct impact on the insect pest scenario, the socio – economic impacts include, for example: l New and intense pest problems l Reduced effectiveness of pest management strategies l Implications for food security l Adaptation of agriculture to changing pest scenarios due to climate l Etc. With those impacts the strategies to cope will include breeding climate – resilient varieties, rescheduling of crop calendars, GIS based risk mapping of crop pests and screening of pesticides with novel mode of actions for better planning of future pest management programs.
