Brown planthopper is one of the species of insects harmful to rice. Rice infected with the hoppers will give low productivity even as d. white. To deal with this situation, the plant protection industry has invented a trap lamp-an active instrument based on directional characteristics of insects. It is considered effective measures and less costly for now. However, the current lamp traps are usually installed next to the House of the officers to be assigned to management of the lamp to trap for the track that has interest in the effects of ambient factors. Currently, the plant protection industry would like to have more scientific basis in the layout should they want to consider light traps and take the climate and geographical element into the installation of light traps but not yet implemented. In this thesis, we present the factors affecting location of hoppers Brown lamp set, through which to conduct Optimization modeling trap placement by simulated approach lights CA. experimental results conducted on the system trap lamp in An Giang Province , Dong Thap and can tho city in the MEKONG DELTA.
