It study on trapping effect of 20 kinds of band light for different pests and nature enemies in the vegetable field, major pests’rhythm of dashing at lamps, and the best effect band which can use in the all year has been chosen. And the main results are as follows:1. chosen the best band for different kinds of pest. L4 is the best trapping effect of band for Plutella xylostella (L.).it trapped 1060 individual, about 9.35 percent in total. CV is 97.4%.L7 is the best trapping effect of band for Helicoverpa armigera Hubner.it trapped 150 individual, about 19.35 percent in total. CV is 84.5%.L19 is the best trapping effect of band for Laphygma exigua Hubner. it trapped 669 individual, about 11.00 percent in total. CV is 61.3%.L4 is the best trapping effect of band for Maruca testulalis Geyer. it trapped 40 individual, about 10.39 percent in total. CV is137.1%.L5 is the best trapping effect of band for Anomala corpulenta Motsch. it trapped 1453 individual, about 11.88 percent in total. CV is 84.1%.L3 is the best trapping effect of band for Agrotis ypsilon Rottemberg. it trapped 228 individual, about 13.33 percent in total. CV is 48.6%.L3 is the better trapping effect of band for Diaphania indica (Saunders).it trapped 66 individual, about 12.60 percent in total. CV is 106.8%.L5 is the best trapping effect of band for Prodenia litura Fabricius. it trapped 209 individual, about 11.87 percent in total. CV is 68.2%.L2 is the better trapping effect of band for Hymenia recurvalis Fabricius. it trapped 936 individual, about 11.87 percent in total. CV is 68.2%.L2 is the better trapping effect of band for Noctuidae and Pyralididae. it trapped 2267 individual and 1914 individual separately, about 8.39 percent and 90.3 percent in total. Noctuidae CV is 65.1%.2. chosen the best band for nature enemy and Staphilinidae. The results of comprehensive evaluation suggest that L12 was the best band to nature enemy and it’s about 0.96 pencent in total insect, L14 was the best band to Staphilinidae and it’s about 3.9% in total insect.3. Every band of light of comprehensive evaluation suggest that L2 was the best choice than others which can control the pest and protect the nature enemy and useful insects, the result was 0.42,and it was analyzed by fuzzy mathematics.4. The research of Female-Male ratio under different band suggest that it’s different reaction between male and female, the male’s rate at lamps was more than the female’s.5. The study on pests rhythm of dashing at lamps suggest that Noctuidae had two peak times at lamps all night, but some one like Laphygma exigua Hubner and Prodenia litura Fabricius had different state, the male at after midnight and the female at the first half of the night. The peak times of Pyralididae and Anomala corpulenta Motsch at the first half of the night.
