摘　　要：经过2年田间试验,研究150 g/L氯虫苯甲酰胺.高效氯氟氰菊酯微囊悬浮剂防治番茄棉铃虫(He-liothis armigera)的效果。结果表明,150 g/L氯虫苯甲酰胺.高效氯氟氰菊酯微囊悬浮剂45.00 g(a.i)/hm2(300 mL/hm2)防治棉铃虫效果最佳,2008年药后1、3、7、14、21 d的防治效果分别为76.03%、86.99%、96.05%、92.11%、86.67%,2009年药后1、3、7、14、21 d的防治效果分别为73.45%、83.68%、92.12%、88.87%、83.09%,均明显高于对照药剂25 g/L功夫水乳剂和250 g/L氯虫苯甲酰胺悬浮剂,防治效果好,且对番茄生长无药害。结合试验和生产实际考虑,推荐150 g/L氯虫苯甲酰胺.高效氯氟氰菊酯微囊悬浮剂防治番茄棉铃虫田间使用剂量为22.50～33.75 g(a.i)/hm2,对水喷雾。The plot experiment results showed that the control efficiency of Lambda-cyhalothrin Chlorantraniliprole 150 g/L ZC against Heliothis armigera of tomato was obviously higher than that of the two standard insecticides.In the year 2008 and 2009,the control efficiency of 1,3,7,14,21 days after spraying reached to 76.03%,86.99%,96.05%,92.11%,86.67% and 73.45%,83.68%,92.12%,88.87%,83.09% respectively,and did no hazard tomato.According to the tests and actual production,lambda-cyhalothrin chlorantraniliprole 150 g/L ZC spray at the dose of 22.50～33.75 g（a.i）/hm2 were recommended.
