Southern pine beetle, Dendroctonus frontalis Zimmerman (SPB), is a significant pine (Pinus spp.) pest in the eastern United States. When population levels are high, SPB use complex chemical signaling to initiate mass attacks and overwhelm the defenses of healthy trees. Host tree volatiles interact with SPB’s aggregation pheromone to enhance or inhibit attractive of SPB. 4-allylanisole, a host volatile previously thought to inhibit SPB aggregation, has recently been observed to enhance attraction of SPB. My goal was to better understand the variable responses of SPB and its predator clerid beetle, Thanasimus dubius F., to 4-allylanisole. Results indicated that 4-allylansiole can greatly enhance attraction of SPB and clerid beetles. 4-allylanisole did not exhibit attractive effects for SPB in the absence of endo-brevicomin. We observed significant interactions between trap configuration and 4-allylanisole. No significant interactions were observed between alpha-pinene, beta-pinene, and 4-allylanisole. This research provides insight into the relationship between SPB and its clerid predator and 4-allylanisole and demonstrates the potential for more effective monitoring efforts for this pest species.
