摘　　要：以小菜蛾成虫为试虫,研究比较了3种不同性质诱捕孔处理的诱捕器对小菜蛾逃逸率的影响。结果表明:锥形防逃逸诱捕孔处理的诱捕器中小菜蛾的逃逸率为1.82%,不放诱芯的逃逸率为14.97%;加防逃逸管诱捕器的逃逸率为4.79%,加防逃逸管不放诱芯的逃逸率为19.73%;直通式诱捕器的逃逸率为31.79%,不放诱芯的逃逸率为40.58%。同种诱捕器加放诱芯与不放诱芯,虫子逃逸几率相差10个百分点左右。Taking adult Plutella zylostella （L.） as material, the effect of 3 different traps on escape ratio of it was compared and studied. The results showed that the escape ratio of conical hole traps was 1. 82% ,and the one without lure was 14. 97%. The escape ratio of conical hole traps with cannulation to avoid pest escaping was 4. 79%, and the one without lure was 19. 73%. The escape ratio of the non-cover traps was 31.79 % ,and the one without lure was 40. 58%. The escape ratio of traps without lure was 10 percent point than the one with lure.
