preparation example Construction

[0031] The present invention also provides a preparation method for the lure core described in the above scheme, comprising the following steps: placing the absorbent cotton in a polyethylene plastic bag, and then dripping the Tianshan Xingkeng beetle plant-source attractant described in the above scheme on the absorbent cotton , to obtain the lure after sealing.

[0032] In the present invention, when the attractant includes trans 2-hexenol, organic solvent and antioxidant, the present invention preferably dissolves trans 2-hexenol in the organic solvent, and then adds the antioxidant and mixes uniformly , and then drop the resulting mixture onto the absorbent cotton; the mixing is preferably carried out on a shaker.

[0033]In a specific embodiment of the present invention, after the addition of the attractant is completed, the present invention preferably seals the polyethylene plastic bag with a sealing machine, then seals it in a sample bag made of aluminum foil, and stor...

Embodiment 1

[0038] The attractant lure core of the Tianshan Xingkeng beetle produced in this example uses trans-2-hexenol purchased on the market, and its chemical purity and stereoisomer purity are both greater than 95%. The pipette absorbs 2mL of trans-2-hexenol, dissolves it in 10mL of 1,3-butanediol solvent, then adds 100 mg of antioxidant BHT, shakes on the shaker until it is completely mixed, that is, it is prepared attractant. Then get the black polyethylene plastic bag (thickness is 12 wires, length 130mm, wide 70mm) that buys on the market and make carrier, transfer and drop the attractant prepared in the absorbent cotton 5g in the black polyethylene plastic bag carrier with pipette , to make a lure for the bark beetle in the Tianshan Star Pit.

[0039] The prepared lures are sealed and packaged with aluminum foil, and refrigerated at 4°C.

Embodiment 2

[0049] The attractant lure core of the Tianshan Xingkeng beetle produced in this example uses trans-2-hexenol purchased on the market, and its chemical purity and stereoisomer purity are both greater than 95%. Take 2mL of trans-2-hexenol, dissolve it in 10mL of methanol, then add 100mg of antioxidant BHT, shake it on a shaker until it is completely dissolved, and then prepare the Tianshan Xingkeng bark beetle attractant. Then take a black polyethylene plastic bag purchased on the market (thickness is 12 wires, length 130mm, width 70mm) as a carrier, transfer and drop the original solution to 5g of absorbent cotton in the black polyethylene plastic bag carrier, and make a small star pit in Tianshan Mountains. Lure for beetles.

Abstract

The invention relates to the technical field of green prevention and control of Tianshan Xingkeng Beetle, and provides a plant-derived attractant for Tianshan Xingkeng Beetle, a lure core, and a preparation method and application thereof. The attractant provided by the invention uses trans-2-hexenol as an active ingredient, has good persistence, attracting activity, stability, specificity and environmental friendliness, and has broad industrialization prospects. The lure provided by the invention has simple structure, simple preparation and use methods, and is especially suitable for large-area promotion in production. The lure core provided by the invention is suitable for the population management of the Tianshan Xingkeng beetle with large occurrence area and complex terrain and topography, can achieve the dual functions of population control of the Tianshan Xingkeng beetle and protection of the host spruce, and has good economical benefits, social benefits and ecological benefits.

Description

technical field [0001] The invention relates to the technical field of green prevention and control of the star beetle in the Tianshan Mountains, in particular to a plant-source attractant for the star beetle in the Tianshan Mountains, a lure core and a preparation method and application thereof. Background technique [0002] Pityogenes spessivtsevi Eggers is an insect belonging to the family Scolytidae, the subfamily Ipinae, the family Ipini, and the genus Pityogenes. This worm belongs to a small species with a body length of no more than 3mm. The male adult has three teeth on both sides of the elytra slope. The first tooth on the slope is smaller than the second tooth, and the second tooth is more developed in the shape of a hook. The adults are quite different. The female adults have pits on the frontal surface, and the teeth of the female adults are obviously less developed than the male adults. This insect is an important borer pest in coniferous forests in my country....
