Abstract
This study was conducted in College of Agriculture University of Mosul during 2004 to show the light color (blue, green, red and white) and light density (100, 160, 250 W) which was used in Hestand light trap on adult trapping of lepidoptera. The effect of color and density of light on adult of some specis of order lepidoptera cutworm attractively was studied, the result showed that the traps with blue color bulb were more effective than of green, red & white color where the average of captivity were the 2.80, 1.93, 0.67 & 0.93 adult night, respectively. The study also showed that there were no significant differences between the traps of the white light density of with 160W bulb power and 250W bulb power which gave average captivity of 7.17 & 7.43 adult night, respectively, while traps of 100W bulb showed lower effect in adult capture.
