Abstract: The peach fruit moth Carposina niponensis Walsingham, is a small moth of Carposinidae in Lepidoptera. According to literature this moth is active at night buthas no phototatic reaction toward light. Five different wavelengths of monochromaticlight (350, 375, 405, 333, 383nm) were tlsed to test its reaction in behavior testapparatus in the laboratory. The result indicated that these five wavelengths of monochromatic light could attract moth, especially the 350nm was more ffective. Field experiments were conducted in the jujube forests Four light traps were placed 50m apart. A 20W black green double light (λ=353, 530nm), a 20W black blue light (λ=355,435-460), a 20W black orange light (λ=355, 560.600nm) togather with the usual 20W blacklight used to make comparison. The results of two years of field experiments indicated that the black green light was most effective in moth trapping. Besides, comparative experiments in moths trapping between light resource and pheromone lure indicated the black green light being most effective.

Key words: Carposina niponensis——phototaxis——monochromatic light
