应用二化螟性诱剂对越冬代二化螟雄蛾进行了大面积诱捕。结果表明:诱杀7d和15d后,诱捕区(包括中心区和边缘带)雄蛾量分别为对照区的4044%和2978%,其中心区的蛾量分别为边缘带的4855%和2465%;诱捕区卵块数仅为对照区的200%~333%,枯鞘率仅为对照区的125%~250%;诱捕区的第一代雄蛾发生量大量减少,诱蛾量仅为对照区的4696%,其中心区的雄蛾量为边缘带的6764%;诱捕区的水稻枯心率仅为对照区的3950%~4475%。应用性诱剂大面积诱捕是防治水稻二化螟的有效方法之一。
Large-area trapping of overwintering polio-combattiocerela aspergillus f. The results showed that the male moth trapping area (including the central area and the marginal zone) were 4044% and 2978% respectively after 7 days and 15 days of trapping, and the moths in the central area were 48% of the marginal zone respectively. 55% and 2465% respectively. The number of eggs in trapping area was only 200% ~ 333% of that in control area, and the rate of dead sheath was only 125% ~ 250% in control area. The generation of male moths was greatly reduced, and the number of moths was only 4696% of that in the control area. The male moths in the central area were 6764% of those in the marginal zone. The trapping rate of rice in the trapping area was only 39% of that in the control area. 50% ~ 44 75%. One of the effective ways to control the rice stem borer is to use large-area trapping lure.
