Pine moth rod type destructive insect attractant

Abstract

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.

Description

technical field [0001] The invention relates to an attractant for pests, in particular to an attractant suitable for trapping and killing pine tree borer pests such as Alpinia monochamus and Alpinia cerevisiae, as well as its manufacturing and application methods.

Problems solved by technology

[0003] In recent years, the prevention and control of these pests has been using measures such as tree trunk spraying at the adult stage, living tree fumigation, etc., which are not only labor-intensive, costly, technically difficult, and the effect is not good, but also pollute the environment to a certain extent. Therefore, There is an urgent need to explore new ways of monitoring and controlling the above-mentioned pests
