Excerpt from The Vegetable Weevil: Listroderes Obliquus

Light Experimenta - Experiments were undertaken to determine whether or not the vegetable weevil would fly, with-the idea in mind that if they did, light traps might be used for control. A large gasoline lantern was set up in a heavily infested field of carrots. The lantern was lighted about seven 0 'clock in the evening and kept lighted until nine o'clock. Surrounding the light were large frames covered with paper smeared with tanglefoot. Besides the white light Of the lamp, blue, amber, red, and green screens were used for a number Of evenings in May when the young adults were emerging from the ground. At no time were weevils seen in flight, but were readily found walking on the ground and feeding on the foliage of potato plants growing closely adjacent to the infested carrot field.
