Agriculture is a principal occupation in Thailand. Every year farmers face pest problems which seriously destroy crops. There are many preventions and exterminations of pest problems, such as mechanical method, physical method, biological method, and chemical method. Using pesticides and chemical method directly affects on agriculturists and consumers, for example, pests are chemical resistant which leads farmers using more and more pesticides. This causes plant residue which is dangerous for consumers, and also affects on environment and ecology. At present, the consumers emphasize on safe and non-chemical food. The producers should be aware of this matter and reduce pesticide to decrease farmers’ and consumer’s health problems by creating non-chemical and pesticide measures. Moreover, agriculturalists has tried to find other ways instead of chemical used such as using lights to tempt pests which is popular way for farmers. However, that way is still lack of electric energy for bulbs because the farm is far away, and trap is also expensive. From this point, the researcher has developed Solar Energy- Based Insect Pest Trap for orchards and vegetable.
