我所近两年推出了利用特制高压汞灯、诱杀棉铃虫成虫的新技术。此灯为特种光谱的450瓦自镇高压汞灯,电源电压220伏。将灯固定在一稳定的三角架上,灯下设1.2米左右的水盆(或水池)一个,水面距灯20～30厘米,灯高1.5～2米,水中加0.15洗衣粉。蛾期,每天傍晚开灯,清晨关灯捞蛾。高压汞灯诱杀棉铃虫的特点是:诱蛾多、控制面积大、不伤害天敌,全年可以方便使用,非常适合社会化服务。与其他防冶措施结合,可以有效地压低虫源基数,使全年防治处于主动地位。它的防治效果表现在以下几个方面:
In the past two years, I have introduced a new technology that uses special high-pressure mercury lamp to trap adults of Helicoverpa armigera. The lamp is a special spectrum of 450-volt self-ballasted high-pressure mercury lamp with a supply voltage of 220 volts. The lamp is fixed in a stable tripod, the lamp is located about 1.2 meters of basin (or pool) a, the surface light from 20 to 30 cm, 1.5 to 2 meters high, plus 0.15 washing powder in the water. Moth, turn on the lights every evening, turn off the light moth early in the morning. High-pressure mercury lamp trapping and killing of cotton bollworm is characterized by: more moths, control of large, do not hurt natural enemies throughout the year can be easily used, very suitable for social services. Combined with other anti-metallurgical measures, it can effectively reduce the base number of insects and make the prevention and control of the whole year take the initiative. Its control effect is manifested in the following aspects:
