Study on Effect of Yellow Lamp by Matrix Control the Cotton Lygus in Cotton Fields

黄光灯矩阵灯光防治棉田盲蝽效果研究结果表明,矩阵黄光灯诱杀到6种盲蝽,诱杀效果高于原色灯对照2.86倍,提升黄光单灯诱杀效果2.70倍;与原色灯相比,棉盲蝽发生时间减少50%,虫口量减少4头/百株,棉幼蕾被害率减少0.75倍,与农药常规防治相比,棉盲蝽发生时间减少25%,虫口量减少4头/百株,棉幼蕾被害率减少0.41倍,表明矩阵黄色光具棉盲蝽防治专用性特点和避免误杀其他有益昆虫优势。

Study on the effect of yellow lamp by matrix control the cotton lygus in cotton fields was conducted,the results showed that the yellow lamps by matrix trapped 6 kinds of cotton lygus, the effect of trapping was 2.86 times higher than the primary color lights, that was 2.7 times higher than single yellow light.Compared with the primary color lights,the last time of cotton lygus occurred was cut down 50 percent, the insect population reduced 4 heads every＇one hundred cottons, rate of infestation of the young bud was reduced 0.75 times.Compared with the conventional control by pesticide, the last time of cotton lygus occurred was cut down 25 percent,the insect population reduced 4 heads every one hundred cotton, rate of infestation of the young bud was reduced 0.41 times.The results showed that yellow light by matrix was special to control cotton lygus and advantaged to avoid to manslaughter other beneficial insects.
