黑光灯是利用特制的光源,对有趋光性害虫进行诱杀的一种高效诱虫工具。它主要诱杀成虫,使其难以繁殖后代,从而降低虫口密度,达到杀虫的目的。现将我们应用黑光灯防治林业害虫的观察试验及杀虫效果简介于后,供参考。一、黑光灯的诱虫原理很多农林害虫有趋光性。这些昆虫眼睛的网膜上有一种色素,能吸收某一波长的光,引起化学反映,刺激视觉神经。而后通过神经中枢指挥运动器官,引起翼或足的运动,使害虫趋向光源飞行。多数农林害虫对3,300—4,000 Black light is the use of a special light source, the phototaxis pests to kill a highly effective trap tools. It is mainly trapping adults, making it difficult to breed offspring, thereby reducing the density of insects to achieve the purpose of insecticide. Now we apply the black light control forestry pests observed and insecticidal effect of a brief introduction for reference. First, black light trap principle Many farmers and pests have phototaxis. These insects have a pigment on the retina of the eye that absorbs light of a certain wavelength and causes a chemical reaction that stimulates the optic nerve. And then through the nerve center command organs, causing the movement of wings or feet, so that pests tend to light source flight. Most agroforestry pairs 3,300-4,000
