Problems solved by technology

[0002] Huashan pine beetle (Dendroctonus armandii Tsai&Li) is an endemic species in my country, widely distributed in Shaanxi, Sichuan, Gansu, Hubei and Henan, etc. It is a destructive pioneer beetle in the Bashan forest area of ​​Qinling Mountains, and mainly harms Huashan pine (Pinus armandii Franch.) and Pinus tabulaeformis (P.tabuliformis Carr.), the average annual growth rate in Shaanxi has almost doubled, and the control is difficult, seriously affecting the sustainable development of forest ecosystems
[0003] In 2006 and 2011, after the Huashan pine beetle broke out in Liuba County, Shaanxi Province and Shennongjia forest area, Hubei, the Huashan pine forest became a disaster year after year, and it became more and more serious, causing a large number of trees to die. Wood, chemical control, biological control, silvicultural measures, etc., but the control effect is not ideal, and because of the characteristics of the insect's strong reproductive ability, multiple and overlapping generations, and hidden life, it is difficult to control

Embodiment 1

[0029] The attractant of D. armandii is composed of the following components: trans-verbenol (tV) 70mg, 3-methyl-2-cyclohexen-1-ol (SD) 40mg, 7-ethyl-5 -Methyl-6,8-dioxbicyclo [3,2,1] octane (EBV) 20mg and 1-methyl-2-cyclohexen-1-ol (MCOL) 20mg, α-pinene 3840mg, Δ3-carene 960 mg, β-pinene 480 mg, limonene 360 ​​mg, β-myrcene 240 mg, and (+)-long leafene 100 mg.

[0030] The method for preparing the attractant of D. armandii is to drop the above-mentioned components into a release carrier of a polyethylene plastic bag containing a fiber mat to form an attractant.

[0031] The method of using the attractant of Pinus armandii is as follows:

[0032] Before the emergence of adults, the trap equipped with the trap core of the present invention is set on a stent 5-10m from the forest edge and a height of 2m. The number of bark beetles caught by the trap is checked every day or every two days until the adult insects At the end of the period, the population monitoring of P. armandii or mas...

Embodiment 2

[0034] The difference between this example and Example 1 lies in the different proportions of the various components of the attractive agent for Dendroctonus armandi:

[0035] Trans-Verbenol (tV) 1mg, 3-Methyl-2-cyclohexen-1-ol (SD) 40mg, 7-ethyl-5-methyl-6,8-dioxbicyclo[3,2 ,1] Octane (EBV) 5mg and 1-methyl-2-cyclohexen-1-ol (MCOL) 7mg, α-pinene 5000mg, Δ3-carene 1000mg, β-pinene 500mg, limonene 400mg, β-Myrcene 300mg and (+)-Longolene 50mg.

Embodiment 3

[0037] The difference between this example and Example 1 lies in the different proportions of the various components of the attractive agent for Dendroctonus armandi:

[0038] Trans-Verbenol (tV) 100mg, 3-methyl-2-cyclohexen-1-ol (SD) 0.2mg, 7-ethyl-5-methyl-6,8-dioxbicyclo [3, 2,1] octane (EBV) 0.006mg and 1-methyl-2-cyclohexen-1-ol (MCOL) 0.015mg, α-pinene 5mg, Δ3-carene 1mg, β-pinene 0.6mg , Limonene 0.5mg, β-Myrcene 0.3mg and (+)-Longolene 0.1mg.

Abstract

The invention relates to a dendroctonus armandi dendroctonus attractant. The active ingredients of the dendroctonus armandi dendroctonus attractant are aggregation pheromone and host kairomone. The dendroctonus armandi dendroctonus attractant comprises the following components with the following releasing rates: trans-verbenol (tV) being 0-10mg/d, 3-methyl-2-cyclohexene-1-alcohol (SD) being 0-3mg/d, 7-ethyl-5-methyl-6, 8-bioxygen bicyclo-[3,2,1] octane (EBV) being 0-3mg/d and 1-methyl-2-cyclohexene-1-alcohol (MCOL) being 0-3mg/d, alpha-pinene being 0-500mg/d, delta3-carene being 0-100mg/d, beta-pinene being 0-100mg/d, limonene being 0-100mg/d and beta-myrcene and (+)-longifolene being 0-100mg/d. The dendroctonus armandi dendroctonus attractant can effectively attract dendroctonus armandi dendroctonus and has extremely high in attraction to bisexual adult insects; the preparation technology is simple and the dendroctonus armandi dendroctonus attractant is convenient to use.

Description

Technical field [0001] The invention relates to an insect attractant, in particular to a pine beetle attractant and a preparation method thereof. Background technique [0002] Dendroctonus armandi Tsai&Li is an endemic species in my country. It is widely distributed in Shaanxi, Sichuan, Gansu, Hubei, Henan and other regions. It is a devastating pioneer toxoid in the Bashan forest area of ​​Qinling Mountains. It mainly harms Pinus armandii Franch. The average annual growth rate of P. tabuliformis Carr. in Shaanxi has almost doubled, and it is difficult to control, which has seriously affected the sustainable development of the forest ecosystem. [0003] After the Huashan pine beetle broke out in Liuba County of Shaanxi Province and the Shennongjia forest area of ​​Hubei in 2006 and 2011, the Huashan pine forest has been damaged year after year, and it has become more and more serious, causing a large number of forest trees to die. The main measures taken successively are: removal of ...
