| 摘 要： | ２０％吡虫啉（康福多）浓可溶剂对温室白粉虱的毒力及其田间药效试验结果表明，２５００～５０００倍稀释液，药后１、３、７、１５天的校正防效为７５．６％～９６．５％，明显优于２０％灭扫利乳油２０００倍稀释液。康福多对温室白粉虱的室内毒力也显著高于灭扫利，其ＬＣ５０值仅为后者的０．０１倍

| Abstract: | Laboratory and field trials were conducted to evaluate the efficacy of imidacloprid to control Greenhouse whitefly. The field effectivenesses of 40～80mg/L of 20% imidacloprid at 1～15 days were 75.6%～96.5%,which were significantly higher than that of 100mg/L of 20% fenpropathrin. Imidacloprid showed stronger toxicity to Greenhouse whitefly than fenpropathrin. Its LC50 was only 1/100 of fenpropathrin s. |
