The invention discloses a botanical attractant for tarssoneus longhorn beetles in yangming and application of the botanical attractant, and belongs to the technical field of deinsectization of
elaeagnus mollis. The botanical attractant is prepared from the following components in parts by
mass: 45 to 55 parts of
butyl acetate, 18 to 22 parts of trans-2-nonenal, 18 to 22 parts of alpha-
pinene, 4 to 6 parts of (E)-4, 8-dimethyl-1, 3, 7-nonelatriene and 4 to 6 parts of beta-
phellandrene. Volatile components of the host
tree species are utilized to attract the
tree species, the
tree species are killed in a concentrated mode after being attracted, the attractant belongs to green, non-toxic and nuisanceless attractant substances, a series of problems caused by chemical prevention and treatment such as many
pesticide residues, environment
pollution easiness, high cost and product safety can be solved, and the method is suitable for large-scale popularization and application. And the problem of difficulty in preventing and treating the pest, namely Yangming tarsogonum longicorn, of
elaeagnus mollis
