Abstract:

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.
