摘要
频振式杀虫灯有效范围防治稻瘿蚊试验表明:杀虫灯辐射半径80 m内防治稻瘿蚊效果在86 %左右,与施用益舒宝颗粒剂18.75 kg/hm2 防治效果相当,辐射半径10 0 m处防效稍差,12 0 m处更差。在水稻无公害标准化生产中,建议控制在10 0 m范围内较好。
The test of controlling rice gall midge by Frequencyvibrancy pestkilling lamp in effective range showed that the effect of controlling the insect was about 86%, which corresponded to that of 18.75 kg Ethoprobos FG per hectare, within 80 meters of the lamp's radiation radius. But the effects of the controlling with 100 meters and 120 meters of radiation radius were decreased significantly and successively. In rice cultivation with the pollutionfree standard, it's proposed to install the lamps with 100 meters of radius range.
