稻纵卷叶螟和二化螟的2种智能监测评价

Two kinds of intelligent monitoring and evaluation system to rice leaf roller Cnaphalocrocis medinalis and rice stem borer Chilo suppressalis

2019—2020年,对桐乡市稻纵卷叶螟和二化螟进行性信息素智能监测,比较黑光灯诱智能监测和传统监测效果。结果表明,在稻纵卷叶螟监测过程中,黑光灯智能监测优于性信息素智能监测和白炽灯传统监测,与传统的人工赶蛾相比,趋势较一致,黑光灯智能监测在一定程度上可以替代人工赶蛾监测。同时我们发现四(2)代稻纵卷叶螟成虫田间数量多,但是黑光灯下数量少,五(3)代稻纵卷叶螟成虫田间数量少,但是黑光灯下数量多。2年对二化螟的监测中发现性诱和黑光灯监测均可以较好地监测到二化螟种群动态,二化螟种群动态年度间差异较大,但同一年份各区域二化螟种群动态基本一致,而诱捕数量差异较大。综上,黑光灯智能监测可以应用于稻纵卷叶螟的监测,二化螟性诱监测和黑光灯监测都可以较好地监测二化螟种群动态,两者互补可以很好地用于监测二化螟。

From 2019 to 2020,a study in Tongxiang City was conducted to compare intelligent pheromone monitoring,black light lamp monitoring with traditional monitoring methods for two pest species:Cnaphalocrocis medinalis and Chilo suppressalis.The results showed that in monitoring C.medinalis,black light intelligent monitoring was superior to both pheromone intelligent monitoring and traditional incandescent lamp monitoring.Compared with the traditional manual moth chasing,the trend was more consistent,and black light intelligent monitoring,to some extent,could replace manual monitoring.Additionally,it was observed that the number of adult C.medinalis of fourth(2)generation in the fields was higher than that under the black light,while the opposite was true for the fifth(3)generation.Over the past two years,both pheromone and black light monitoring effectively tracked the population dynamics of C.suppressalis.For C.suppressalis,there were significant annual variations in the population dynamics,but within the same year,the dynamics were consistent across different regions,despite significant differences in capture numbers.In conclusion,black light intelligent monitoring can be applied to monitor C.medinalis,and both pheromone monitoring and black light monitoring can effectively track the population dynamics of C.suppressalis,with the two methods complementing each other for effective monitoring.
