ABSTRACT

The effects of illumination of four LED wavelengths (440~450 nm, 460~465 nm, 600~605 nm and 490~495 nm) on egg quantity, oviposition rate and adult longevity of Ectropis grisescens Warren were investigated in laboratory. The results showed that the total egg quantity, oviposition rate and adult longevity were all affected. The egg number every female adult of E. grisescens Warren was reduced 37.36%, 26.17%, 41.88% and 35.11% contrast to the control. The average oviposition rate reduced 16.61%, 11.44%, 11.81% and 8.86% respectively with the supply of four wave lengths at night. Meanwhile, the pre-oviposition period and oviposition period were affected by the four illumination deals of wave lengths. The longevity of male and female adult was decreased, and the male adult was longer than that of female adult under each treatment of E. grisescens Warren. The eclosion rate of four deals were affected respectively. The purpose was screen out the best spectrum possible by study the effect of spectral treatment on biological habit of E. grisescens Warren. The results provide a scientific basis for the use of phototaxis to the integrated management of E. grisescens Warren.
