Tomicus piniperda attractant

Abstract

The invention discloses a tomicus piniperda attractant and application thereof. The tomicus piniperda attractant is prepared from the following components of 0.2 to 0.8 part of alpha-pinene, 0.4 to 0.6 part of beta-pinene, 0.6 to 3 parts of trans-beta-ocimene, 0.4 to 2 parts of 1-octene-3-alcoho, 3 to 8 parts of cis-11-hexacadienal, 1 to 5 parts of n-octanal, and 30 to 70 parts of acetaldehyde. The invention also provides a use method of a dendroctonus armandi attractant; the attracting effect on dendroctonus armandi is obvious, and the dendroctonus armandi can be ecologically prevented and controlled. The tomicus piniperda attractant has the advantages that the environment-friendly effect is good, the cost is low, and the simplicity in use is realized.
