【Abstract】 The trapped pest number under the high efficiency energy saving double-wave trapping light was 24.21% higher than that under the straight pipe double-waves trapping light, and the natural enemy number was 33.38% lower in average. Field survey indicated that the pest populations were reduced 43.33%～75%, the damage was decreased by 35.17%～78.57% and 44～272 yuan/667m~2 would be redeemed in earthnut and cauliflower fields. The new light wave peak value in this trapping light may result in its trapping capability.更多还原
