Embodiment 1

[0022] A repellent of monochamus alternatus, which consists of wormwood, a solvent and a synergist, and its components are calculated by weight percentage: 10-30% of wormwood, 60-80% of a solvent, and 5-10% of a synergist %; the solvent is one or a mixture of ethanol and glacial acetic acid; the synergist components are benzaldehyde, n-ethanol, citral, oxalic acid, citric acid, methyl dihydrojasmonate, eugenol, glycerin , salicylic acid, and several mixtures of iridoid glycosides; the content of artemisinin is 10-30%, preferably 15-25%; the content of solvent is 60-80%, preferably 65-75%; The content of synergist is 5-10%, preferably 7-9%.

[0023] A preparation method of Monochamus alternatus repellent, comprising the steps of:

[0024] Step 1: Preparation of raw materials: 150ml wormwood, 750ml ethanol, 20ml benzaldehyde, 20ml citral, 10ml oxalic acid, 10ml citric acid, 10ml methyl dihydrojasmonate, 20ml eugenol, 10ml iridoid glycosides;

[0025] Step 2: Deployment and mix...

Embodiment 2

[0027] Embodiment 2 is substantially the same as Embodiment 1, the difference is:

[0028] Step 1: Preparation of raw materials: 200ml wormwood, 700ml ethanol, 10ml benzaldehyde, 10ml n-ethanol, 10ml citral, 10ml oxalic acid, 10ml citric acid, 10ml methyl dihydrojasmonate, 10ml eugenol, 10ml glycerin , 10ml salicylic acid, 10ml iridoid glycosides;

[0029] Step 2: Deployment and mixing: add 200ml wormwood and 700ml ethanol to a 1000ml container, add 10ml benzaldehyde, 10ml n-ethanol, 10ml citral, 10ml oxalic acid, 10ml citric acid, 10ml methyl dihydrojasmonate, 10ml eugenol, 10ml glycerol, 10ml salicylic acid, 10ml iridoid glycosides, and finally stir and mix evenly.

Embodiment 3

[0031] Embodiment 3 is substantially the same as Embodiment 1, the difference is:

[0032] Step 1: Raw material preparation: 250ml wormwood, 650ml ethanol, 10ml benzaldehyde, 20ml n-ethanol, 10ml oxalic acid, 20ml methyl dihydrojasmonate, 10ml eugenol, 10ml glycerol, 20ml salicylic acid;

[0033] Step 2: Deployment and mixing: add 250ml wormwood and 650ml ethanol to a 1000ml container, then add 10ml benzaldehyde, 20ml n-ethanol, 10ml oxalic acid, 20ml methyl dihydrojasmonate, 10ml eugenol, 10ml glycerin , 20ml salicylic acid, and finally stir to mix evenly.

[0034] The actual use effect of the above-mentioned Monochamus alternatus repellent is illustrated by experiments below.

[0035] The repelling test result (500ml / of table 1 embodiment 1-3, cooperates trap to hang and between forests)

[0036]

Abstract

The invention discloses a monochamus alternatus repellent. The repellent comprises in percent by weight: 10-30% of p-allylanisole, 60-80% of a solvent and 5-10% of a synergist. The invention also discloses a preparation method of the monochamus alternatus repellent. The beneficial effects are as follows: the monochamus alternatus in the pine forest can be significantly repelled by the synergisticaction of the active components with good repelling effects, the carrying and spreading of bursaphelenchus xylophilus is reduced, the survival rate of pine trees is improved, the flooding of bursaphelenchus xylophilus can be effectively prevented and treated, and the transmission path is cut off. The biological prevention and treatment concept is used, the preparation of the repellent is simple and convenient, the cost is low, the resistance to monochamus alternatus cannot be caused for the long-term use, and thus the repellent is suitable for the hanging and slow-release use in a large area in the pine forest.

Description

technical field [0001] The invention belongs to the technical field of prevention and control of forestry harmful organisms, in particular to a monochamus alternatus repellant and a preparation method of the repellent. Background technique [0002] Monochamus alternatus is an important dry-boring pest of pine trees in my country, and it is also the main vector insect of pine wood nematode, a devastating disease of pine trees. And the key role of assisting pathogens to invade the host. [0003] Monochamus alternatus adults are the medium for nematode transmission. After adults go out from the xylem, nematodes attach to the body surface, but most of the nematodes are in the body, and the head and chest are the most, and can be distributed in the entire tracheal system. 1 adult The number of maintained nematodes can reach up to 289,000. Generally, 2-3 weeks after adult eclosion goes out, the nematodes leave the worm body, and the rate of shedding is about 43-70%. The detached n...
