摘　　要：2007～2008年田间试验表明,50%灭蝇胺可溶性粉剂(SP)有效成分用量75.0、112.5和150.0g.hm-2,药后3～10d对菜豆美洲斑潜蝇的防效分别为85.34%～88.02%、91.00%～92.01%和92.59%～95.06%。对照药剂50%灭蝇胺可湿性粉剂(WP)有效成分用量150.0g.hm-2,药后3～10d的防效为90.01%～93.71%。50%灭蝇胺SP有效成分用量75.0g.hm-2处理药后3、7、10d的防效显著低于对照药剂,而112.5、150.0g.hm-2处理药后3、7、10d的防效与对照药剂差异均不显著。2007年和2008年两年间的防治效果没有显著差异,并与8a和4a前的试验结果基本一致,灭蝇胺对美洲斑潜蝇北京种群的敏感性和防效优良。The efficacy of 50 % cyromazine SP to Liriomyza sativae in the kidney bean field were investigated in 2007 and 2008. The results showed that control effects of 50 % cyromazine SP were 85.34 % -88.02 % , 91.00 % -92.01% and 92.59 % - 95.06 % 3 - 10 days after spraying 75.0 g, 112.5 g, 150.0 g effective insecticide per hectare, respectively. Control effects of 50 % cyromazine WP were 90. 01% -93.71% 3 - 10 days after spraying 150. 0 g effective insecticide per hectare. There were no significant differences in control effects between high dosage of 50 % cyromazine SP and 50 % cyromazine WP. The results of 2007 and 2008 didn＇t find significant differences in control effect, and basically identical with those of four years and eight years ago. It confirmed that 50 % cyromazine SP was excellent for effective control of Liriomyza sativae in the fields.
