| Abstract | 133 Abstract— Rice is the main economic and household consumption crop of the people in Phatthalung Province and all over Thailand. Phatthalung province, especially Amp hoe Phapayorm and Amphur Khuankanun are the importa nt area of rice production in southern region of Thailand. However, rice farming has been decreasing overtime as influenced by several factors such as flood, rice price recess ion, diseases, insect and pests. Insects and pest a lways make difficulties and damages to the farmers due to the outbreaks and they destroy crop rapidly and make da mage to crop product significantly. The important rice insect pe st in Amphoe Phapayorm and Amphur Khuankanun is ric e bug (Leptocorisa oratorius (Fabricius)). The outbreak o f the bug is in the early rainy season. This study aimed to apply of Geographic Information Systems (GIS) to assess the spr ad of rice bug in Amphoe Phapayorm and Amphoe Khuankanun in order to identify areas that are vul nerable to the spread and outbreak of rice bug to p revent yield loss and find out the prevention and the method to get rid of rice bug properly and correctly. From the st udy, the ideal conditions for the outbreak are weed-full area as that area can be the suitable habitat of the bu g, therefore, the rubber plantation area adjacent to the rice field can be t h best habitat of the rice bug . The level of rice bug out break has decresing over the distance from the rubber plantat ion, the severity showed the most severe in 50 m. ra dious, and the most light of the rice bug outbreak was found in 350 m. radious ar ound the rubber plantation. After evaluating the ar prone to be damaaged by the rice bug of the sample area – Makoknua sub-dist rict, Khuankanun distrtct, the result showed that onl y 6% of rubber plantation can cause the rice bug outbreak more than half of t otal area, the most severe and the severe was about 16% and 25% of total area, respectively. |
