400 Proceedings of the Princess Maha Chakri Sirindhorn Congress Thailand’s extended drought and some insects migrations During 2012 - 2013 the whole area burned by forest fire in Thailand was almost 6,000 ha which being northernThailand of 67% (Forest Fire Control Division, 2015). The fire areas consist of Mixed Deciduous forest, Dry Dipterocarp forest, forest plantations and dry Evergreen forest. The situation of forest fire (Figure 3.) has frequently occurred every year particularly during dry seasons of Dec - Mar. The fires were mostly caused by the villagers who burn (Swidden) the forest for farming and/or expected for the budding of some wild edible vegetables and mushrooms (Singhakant 2012). The burning of the forest by both natural causes and human being exploitation from the forest edible items led to severe damage to both living organism and the environments. The long term accumulation of haze and dust in the air caused the hazards to human when it was exceed the safe level (Singhakant 2012). In addition to the local forest fire inThailand that cause the damage to the environments for all living organism and especially insects, the global warming also play significant role for climate change inThailand. As acknowledgedworldwide, themajor causes of the greenhouse gases emission that causes the global warming especially CO 2 is the development of economy and industry. In Thailand the average temperature trend was continuously increasing and forecasted to be rising in the near future (SEA Research and Training on Global Changes 2011). The recent decade’s temperature trend shows continuously rising andwould be continue in the years to come (Figure 4). Environmental changes due to climate change led to the movement of honeybees from forest to urban areas such as Apis Dorsata to Mae Fah Luang (Wongsiri 2011) (Figure 5) and Chulalongkorn Universities which are in the city regions.
