Interpretive Summary: The Asian longhorned beetle (ALB) is a polyphagous invasive species which is considered to be one of the most serious quarantine pests attacking deciduous trees worldwide. We previously identified the male produced attractant. In this study, activity of the synthetic version of the attractant and a different trap design were evaluated with plant volatiles in China. Our result showed that the male-produced attractant combined with specific plant volatiles was attractive under field conditions. Laboratory assays demonstrated that brown color could synergize both male and female attraction as visual cues. Our findings provided valuable information that will enable scientists to develop more reliable and efficient trapping systems for ALB infestation detection and population monitoring. The information will be used by researchers and companies interested in biological control of ALB.

Technical Abstract: The Asian long horned beetle (ALB), Anoplophora glabripennis, is a well-known stem borer with high polyphagous properties causing frequent outbreaks in northeast China. An attractant-based trap is needed to improve the sensitivity, reliability, and efficiency for detection of the beetle. In this study, the effects of attractants, trap types and color synergy of a trapping system were evaluated. Attractant blends comprised of the male-produced, two-component pheromone plus plant volatiles were used in the field in Hengshui city. Plant volatiles (e.g., 1-pentanol, and 2-pentanol) in combination with male pheromones increased the mean number of trapped ALB compared to the pheromone alone. Males responded better than females to traps baited with plant volatiles alone, whereas traps emitting plant volatiles plus pheromone, regardless of trap type, captured more females than males. The ALB-trapping efficiency of a modified flight intercept panel trap was more than ten times as high as a wood borer panel trap and 1.2 times a flight intercept panel trap. The 1-pentanol and 2-pentanol attractants alone or in combination with male-produced pheromone were more effective for monitoring ALB than common lures. In laboratory Y-tube olfactometer experiments, the color brown was better at increasing attraction of both males and females to 1-pentanol, 2-pentanol, 1-pentanol + pheromone, and 2-pentanol + pheromone compared to the clear-glass control arm. The findings provide a reliable and effective trap system to monitor ALB infestations.
