395 Proceedings of the Princess Maha Chakri Sirindhorn Congress CLIMATE CHANGE IMPACT ON SOME INSECT POPULATION DYNAMICS Chalinda Ariyadet, Siriwat Wongsiri and Chanwichai Suksawat Interdisciplinary Agriculture, Maejo University Abstract: Global warming is well known as a major cause of climate change particularly the rising temperature that primarily effects the whole ecosystems. Literature review on impact to the insects and insect pests has shown that higher temperature affects their overall life dynamics. Higher temperature effects insect and insect pest in all aspects such as physiology, habitats, population diversity and feeding behavior. Warmer temperatures generally influencing more rapid physical development of insects that leads to better chances of survival as shown from many studies. It could favor the reproduction to the Platypodid that consequence in outbreak such as in Korea and Japan. The Nezara Viridula in Japan has migrated up northward to escape the original warmer areas to live in cooler climate is an example of geographical shift of the habitat affected by global warming. In northern Thailand the forest fires in the dry season has severely damaged lots of natural insect habitats. The fire had destroyed mostly small weeds and cultivars that have been home to various insects in natural. Currently there have been obvious evidence of the situation as bees (Apis Dorsata) nested in the urban area at Mae Fah Luang University in Chiang Rai province, Thailand. Arthropods are the most diverse and abundant living organism comparing to others and vertebrates. Ecological changed due to climate changed can be significantly harmful to them as they are highly vulnerable. The relative abundance of different insect species may change rapidly due to climate change. Honeybees have been largely influenced by climate change in all aspects. It is the most important economic insects on both food industrial and agriculture. Rising temperature causes their physiology and behavior disturbance. The floral environment quality is altered that define the new distribution range that can affects to the competition among species and races. Environmental change also cause the new diseases and parasites. In conclusions the climate change as caused by global warming affects all living organism and environment. Insects and insect-pests as living organisms that related and influenced human in various aspects have been unavoidable effected. The growth rates was directly affected by temperature change. Some species develop faster in the higher temperature conditions. Some moved to live in cooler environments and cause the outbreak and damages to the agricultural crops. Lastly their survival were depended upon their adaptation to the new environmental stress that rapidly changed and increasing by the human activities. Introduction Insect is a member of Arthropods that is most abundant and diverse of all living organism (Gregory et al. 2009) (Table 1). Insect population dynamics as affected by global warming have been studied and discussedworldwide (e.g. Kamata et al., 2002, Netherer and Schopf 2010, Moraal
