为进一步提高对稻纵卷叶螟性诱剂诱集成虫的效果,完善稻纵卷叶螟性诱剂监测技术,开展了诱捕器不同设置高度对稻纵卷叶螟成虫诱集效果影响的研究。结果表明,随着诱捕器设置高度的增加,无论是累计诱集数量、日均诱集数量,还是日最高诱集数量,均呈下降趋势。其中以诱捕器底部与水稻植株顶部相平设置高度的诱捕器的诱集量最大,对成虫发生高峰期的监测效果最好。
In order to further improve the effect of trap inducing adults of Cnaphalocrocis medinalis and to improve the monitoring technique of sex traps of Cnaphalocrocis medinalis, the effects of different height of traps on entrapment of Cnaphalocrocis medinalis were studied . The results showed that with the increase of the height of the trap, both the cumulative number of traps, the average number of traps per day, and the maximum number of traps per day all showed a downward trend. Among them, the traps at the bottom of the traps and the top of the rice plants were the most abundant traps, and the monitoring effect on the adult peak was the best.
