Abstract

Maize weevilSitophilus zeamais (Motsch.) is the most important pest on the commodity serial in stored grain, can cause yield loss of 30-80%. This research is aimed to know the role of some light colors to the preference of pest maize weevilS. zeamais to the shelled seed of corn crop. This research was done from November 2016 until January 2017 at Insectarium of pest and crop disease major of agriculture faculty at sriwijaya university. The research method used was complete randomized design with 6 treatments which was with non-lamplight, red lamplight, yellow lamplight, green lamplight, blue lamplight, and white lamplight were repeated for 4 times. This research used the tool which was modified from jar. The jar with non-lamplight treatment was the jar that was most visited by S. zeamais. The research result showed that the light colors of each jar treatment did not significantly affect to the level of S. zeamais preference, but significantly affected to the jar that was not given any light color treatment. The average of nonlamplight color was 40,00 pieces, the average of red lamplight was 14,25 pieces, the yellow lamplight was 10,25 pieces, the green lamplight was 9,00 pieces, the blue lamplight was 14,25 pieces, and the white lamplight was 12,25 pieces. Thepercentage of S. zeamais attack 28,38% to non-lamplight color, the red lamplight 4,21%, the yellow lamplight 3,93%, the green lamplight 2,81%, the blue lamplight 3,67%, and the white lamplight 3,45%. The total of new S. zeamais population to non-lamplight was 127,25 pieces, followed by the blue lamplight treatment with the average 20,75 pieces, and then the red lamplight 17,50 pieces, the white lamplight 13,00 pieces, the green lamplight treatment 9,00 pieces, and the yellow lamplight 8,50 pieces. The corn weight loss to non-lamplight was 4,13%, followed by the yellow lamplight treatment 2,08%, the red lamplight 2,00%, the white lamplight 1,98%, then the blue lamplight 1,95%, and the last was the green lamplight 1,88%.
