对生姜3种(斜纹夜蛾、甜菜夜蛾、亚洲玉米螟)主要害虫性诱剂的诱捕效果进行了试验。结果表明,3种害虫诱捕量的变化趋势能反映其在田间的发生规律。常规化防区姜苗被害率最高,正常施药诱捕区次之,少施药诱捕区最低。前者与后两者的差异达到显著水平。少施药诱捕区防治成本最低。
The trapping effects of the major pest attractants of ginger (Spodoptera litura, Spodoptera exigua, Asiatic corn borer) were tested. The results showed that the trend of trapping amount of three kinds of pests could reflect its occurrence law in the field. Conventional ginger seedlings killed the highest rate of injury, followed by normal pesticide trapping zone, the lowest pesticide trapping area. The difference between the former and latter reached significant level. Less drug trapping area prevention and control costs the lowest.
