Control of locusts traditionally relies on chemical ***,chemical control had led to serious environment problems,while light trap techniques based on manipulating insect phototactic responses,are proposed to use for plague locusts *** key to high efficiency of the trap is to decide the photoelectric reaction intensities on the positive phototaxis of *** study compared the visual reaction effects of locusts with their phototactic photosensitivity through the use of spectrometry and behavior investigations,to obtain the influences of the visual spectrum characteristics on locusts positive *** results showed that the visual absorption of photons of mixed spectral light and the visual glimmer reaction of the locusts with migratory spectrum characteristics of the peak wavelength of LED lights,reflected the degree of the visual photosensitivity to light photons absorbed by the *** visual photosensitive response intensity and the phototactic aggregation effect stimulated by violet light were the most effective,showing that violet light of locusts visual trending sensitivity was consistent with the short sensitive spectrum light of insects visual electrophysiology,whereas the timeliness of the visual photosensitivity reaction and the induction effect was superior under orange light,showing that the biological behavior of locusts visual physiology reaction caused by orange light regulating locusts light rhythm was ***,weak light resulted in stronger visuospatial orientation in terms of the phototaxis of locusts and stronger light resulted in the better visual orientation towards the light *** results indicated that optical wave properties could affect the visual absorption of spectral light photons,which resulted in different visual responses to different optical frequency energies and restricted the visual bio-photosensitive induction activity of *** study provides new understanding of positive
