Abstract: Most insects harm forest intensely,Large amounts of pharmaceuticals have been used toeliminate those insects in the cost of money and polluted environment,However,luringinsects into fishpond with moth-trapping lamps is beneficial both in the biological preven-tion of insects and in providing animal food for fish cultivation,The comparative experi-ments indicate that fishes in fishpond with trapping lamps grow better than in thatwithout lamp.If the aboundant resources of forest insects are made full use for fish cultiva-tion,the economic and ecological benefits of agriculture will be increased considerably.
