多年试验证明,单管黑白双光灯诱虫效果明显优于黑光灯,防治棉铃虫及棉田玉米螟有较好效果。而对天敌的杀伤远比黑光灯低。然而,单管黑白双光灯的制造比较麻烦,影响产品质量与数量。为减少工序便于生产,又保持这一灯型的特色而不影响诱虫效果,设想进行改进。在有关灯管厂的支持下,生产了我们设计的混粉灯。1981—1983年的试验表明,对昆虫的引诱力较为明显。现将结果报道如下。 一、材料与方法 (一)灯管种类与来源 单管黑白双光灯(下称黑白灯)20瓦,单管黑蓝双光灯(下称黑蓝灯)20瓦,混粉一号灯20瓦,混粉二号灯20
Years of experiments have shown that single-tube black and white double light trap effect was significantly better than black light, cotton bollworm control and cotton borers have better results. The killing of predators is much lower than black lights. However, the production of single-tube monochrome white light is cumbersome, affecting product quality and quantity. To reduce the process for ease of production, but also to maintain the characteristics of this lamp without affecting the effect of trapping, envisaged to be improved. With the support of the lamp factory, we produced the powder mix lamp designed by us. Experiments from 1981 to 1983 showed that the attraction to insects was obvious. The results are reported below. First, the material and methods (A) lamp types and sources Single-tube black and white double light (hereinafter referred to as black and white light) 20 watts, single tube black and blue double light (black and blue light) 20 watts, 20 watts, mixed powder two lights 20
