Embodiment 1

[0026] The specific technological process of manufacturing method of the present invention is as shown in accompanying drawing:

[0027] (1) Process dry pine branches into fragments (slicing machine or manual splitting can be used), 0.3-1cm thick, length ≤ 3cm, width ≤ 2cm, put 25kg fragments into a traditional Chinese medicine extraction kettle for extraction;

[0028] (2) Add 75 liters of absolute ethanol, cook at 78-80°C for 2 hours, then concentrate for 1 hour, and concentrate into concentrated ointment and crystals, that is, pine tree extract ointment;

[0029] (3) Take the extract and add the solvent absolute ethanol, add it to the filling machine, stir manually or mechanically (15 times / min), stir for 15 minutes, and control the temperature at 30°C (controlled by air conditioner) until it is fully dissolved and prepared to be saturated After standing still, take the supernatant and add 0.1% 6.D-isoascorbic acid to mix evenly, which is the finished attractant. This attr...

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. Background technique [0002] Pinaceae plants, including Chinese pine, red pine, black pine and other trees, are evergreen in four seasons, have excellent characteristics such as barren resistance, drought resistance, salt and alkali resistance, and long life. main tree species. In recent years, pine tree borer pests, mainly pine monochamus and monochamus, have become more and more harmful. In addition, these insects can also infect a kind of nematode disease and cause the death of pine trees in patches. my country's pine trees are seriously harmed by pine xylophilus. Guangdong, Guangxi, Yunnan, Fujian, Jiangxi, Hunan, Zhejiang, Shanghai, Anhui, Jiangsu, Hubei, Chongqing, Sichuan, Shandong 14 provinces and cities,...
