ABSTRACT

Simple Summary The Asian longhorned beetle Anoplophora glabripennis (ALB) is a serious wood borer of hard-wood trees. Populus alba var. pyramidalis (PaP) is the predominant shelterbelt tree species in northwestern areas of China and has been threatened by ALB. A feasible way to protect PaP from ALB is to improve its ability to resist pest attacks. Though the effect of MeJA has been tested in many plants, this is the first case thoroughly studied in a poplar species against a wood borer. Because it is a challenge to control ALB, our results not only demonstrate the response of a poplar species to wood borer infestation but also present an alternative method for poplar protection.
