双波诱虫灯能同时发出长短两列光波,具有比同功率20瓦黑光灯诱虫量高、害虫测报准确等优点。1991年以来已在全国16个省市的部分地区推广应用。目前,主要应用于害虫测报、害虫防治及养殖业。现将这几方面的使用情况整理如下。1.用于害虫测报,虫蜂明显,预报准确。多年观察表明,双波灯较黑光灯诱虫量提高一倍,灯下主要粮棉害虫的高峰明显,预报准确。南方棉区严重发生的四代棉铃虫在双波灯下蜂次出现率100%,而黑光灯下仅为55.56%;1～3代玉米螟在双波灯下出现率平均为96.29%,而在黑光灯下仅为77.78%,而且双波灯下的蛾峰与卵巢解剖观察的发育进度相一致;用
Two-wave trap light can simultaneously issue two long and short light waves, with the same power 20-watt black light trap insect infestation, insect pests reported accurate and so on. Since 1991, it has been applied in some areas of 16 provinces and cities nationwide. At present, mainly used in pest forecasting, pest control and aquaculture. The use of these aspects are summarized below. 1. For pests measured, insects obvious, accurate forecast. Years of observations show that double-wave light more than black light trap to double the amount of pests, the main light cotton pests obvious peaks, accurate forecasts. Four generations of cotton bollworm in the southern cotton area occurred 100% under the dual-wave lamp, but only 55.56% under the black-light lamp. The average occurrence rates of the first to third generations of corn borer under the dual-wave lamp were 96.29% Only 77.78% under the black light, and the moth peak under the dual-wave lamp is consistent with the developmental progress of ovarian anatomy;
