The invention discloses a pine stem-borer attractant, which is prepared by a pine extract and a
solvent. The main compositions of the pine stem-borer attractant by weight percent are 42 to 56 percent of alpha-
pinene, 11 to 23 percent of beta-
pinene, 5 to 10 percent of cinene, 3 to 5 percent of
longifolene, 1 to 3 percent of
caryophyllene and 15 to 30 percent of the
solvent. The manufacturing method comprises the following steps: pine splinters are added with adequate
solvent, cooked for 2 hours at a temperature of between 78 and 85 DEG C, and concentrated for 1 hour into cream and crystals; the cream and the crystals are then added with
anhydrous alcohol and stirred until the solution is fully dissolved, and a saturated liquid is prepared; and a supernatant is taken and added and uniformly mixed with 0.1 percent of 6.D-arabo-
ascorbic acid, namely an attractant liquid is obtained. The using method is to entrap pests by utilization of a special trap. The attractant has good inducing function on pests such as pine sawyer, ahropalus rusticus and so on; the continuous
effective time of each
bottle of liquid medicines is more than 15 days; and the attractant not only has high attractive activity but also does not pollute the environment, has low cost and simple manufacturing technique, saves the cost and is safe, direct, environment-friendly and high-efficiency.
