Abstract:

[Objectives]  Phaenops yin Kubáň&Bíly is an important bark beetle endangering Pinus tabulaeformis Carr. in western areas of Beijing city. Studies of the behavioral responses of P. yin to the volatiles of different tree species provide a foundation for developing plant-based attractants for this pest. [Methods]  The preferences of virgin adult P. yin for the foliage of different tree species were first observed in cages under laboratory conditions. A Y-tube olfactometer was then used to test the relative attractiveness of volatiles from P. tabuliformis and Pinus bungeana and the quantity of foliage of both tree species consumed by male and female adults was also measured. [Results]  Adult P. yin did not land or feed on the branches of the broad-leaved species Populus tomentosa, Sophora japonica, and Salix babylonica. However, both female and male adults landed and fed on the needle-leaved species P. tabulaeformis and P. Bungeana. Although they also occasionally landed on another needle-leaved species, Cedrus deodara, they did not feed on that species. Olfactory bioassays show that the odor of needles and phloem of P. bungeana and P. tabulaeformis, were significantly more attractive to female adults than the clean air control. P. bungeana needles were slightly more attractive to P. yin females than those of  P. tabulaeformis, and female beetles also consumed a slightly greater amount of P. bungeana needles than those of P. tabulaeformis, but these differences were not significant. The odors of P. bungeana and P. tabulaeformis needles were significantly more attractive to adult male beetles than the clean air control, but the phloem odor of P. tabulaeformis was no more attractive to adult male beetles than the control. P. tabulaeformis needles were slightly more attractive to male beetles than that those of P. bungeana but this difference was not significant. However, adult males consumed significantly more P. tabulaeformis needles than P. bungeana needles. [Conclusion]  Broad-leaved trees appear to repel P. yin adults, which preferred the needle-leaved species P. tabuliformis and P. bungeana to the other tree species tested. Although there is no record of P. bungeana being infected by P. yin in field, our results suggest that Pbungeana is a potential host of P. yin. The results of this study provide a foundation for developing new plant-based attractants and repellents for P. yin that could allow the “push-pull” management of this pest in the field.
