Evaluation on the application effect of Hyphantria cunea sex pheromone domestic lure and intelligent monitoring equipment

Pheromone lures of Hyphantria cunea in China are historically dependent on imports from foreign sources, but domestic products become available recently and gradually. This experiment aimed to evaluate the effectiveness of H. cunea lures and the AIM-lite-DL intelligent pest monitoring device. The study compared independently developed H. cunea lures (Z1-Z5 type) by Pherobio Technology with an imported lure (R type) from Japan in lure screening experiments. Furthermore, optimized lures (Za-Zc type) were also compared with two other H. cunea lures (N type and H type) and the imported lure (R type) regarding lure effectiveness. The monitoring capability of the AIM-lite-DL intelligent pest detection device for H. cunea was also investigated. The results indicated that Z1, Z2, Z3, and Z5 type lures had a greater attraction effect than R type lures, where the insects attracted by Z type lures were approximately 1.2 to 2.8 times that of R type lures The Za, Zb, and Zc type lures performed better than N and H lures, with no significant difference compared to R lures. The insects attracted by Z type lures were approximately 8.5 to 33.7 times that of N-type and H type lures. Population dynamics data for H. cunea gathered using Pherobio's intelligent monitoring device aligned with those obtained from unitraps. The intelligent monitoring device achieved an average recognition accuracy of over 90%. Therefore, the sex pheromone lure produced by Pherobio was suitable for monitoring H. cunea, and the intelligent monitoring device demonstrated high counting accuracy, making it effective for using with domestically produced lures (Z1 type) made by Pherobio.
