Problems solved by technology

[0002] The Huashan pine beetle (Dendroctonus armandii Tsai&Li) is a unique species in my country, widely distributed in Shaanxi, Sichuan, Gansu, Hubei and Henan, etc., and is a destructive pioneer beetle in the Bashan forest area of ​​the Qinling Mountains. It mainly harms Huashan pine (Pinusarmandii Franch.) and Chinese pine ( P.tabuliformisCarr.), the average annual growth rate in Shaanxi is 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] Huashan pine beetle attractant is composed of the following components: trans-verbenol (tV) 70mg, 3-methyl-2-cyclohexen-1-ol (SD) 40mg, 7-ethyl-5 -Methyl-6,8-dioxobicyclo[3,2,1]octane (EBV) 20mg and 1-methyl-2-cyclohexen-1-ol (MCOL) 20mg, α-pinene 3840mg, 960 mg of Δ3-carene, 480 mg of β-pinene, 360 mg of limonene, 240 mg of β-myrcene, and 100 mg of (+)-longifolene.

[0030] The preparation method of the Huashan pine beetle attractant is that the above-mentioned components are dropped into the release carrier of the polyethylene plastic bag equipped with fiber felt sheets to make lure cores.

[0031] The method of using the Huashan pine beetle attractant is as follows:

[0032] Before adult eclosion, the trap that lure core of the present invention is housed is arranged on the support that distances from forest edge 5-10m and height is 2m, checks and records the bark beetle quantity that trap is lured once every day or every two days, until adult At the end of the per...

Embodiment 2

[0034] The difference between this embodiment and embodiment 1 is that the ratio of each component of the Huashan pine beetle attractant is different:

[0035] Trans-verbenol (tV) 1mg, 3-methyl-2-cyclohexen-1-ol (SD) 40mg, 7-ethyl-5-methyl-6,8-dioxobicyclo[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, 300 mg of β-myrcene and 50 mg of (+)-longifolene.

Embodiment 3

[0037] The difference between this embodiment and embodiment 1 is that the ratio of each component of the Huashan pine beetle attractant is different:

[0038] Trans-verbenol (tV) 100mg, 3-methyl-2-cyclohexen-1-ol (SD) 0.2mg, 7-ethyl-5-methyl-6,8-dioxobicyclo【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 , 0.5 mg of limonene, 0.3 mg of β-myrcene, and 0.1 mg of (+)-longifolene.

Abstract

The invention relates to a Huashan pine bark beetle attractant, whose active ingredients are aggregation pheromone and host kaimonin. Each component and its release rate in the Huashan pine beetle attractant of the present invention are trans-verbenol (tV) 0-10 mg / d, 3-methyl-2-cyclohexen-1-ol (SD), 7 -Ethyl-5-methyl-6,8-dioxobicyclo[3,2,1]octane (EBV) and 1-methyl-2-cyclohexen-1-ol (MCOL) 0-3mg / d, α-pinene 0-500 mg / d, Δ3-carene, β-pinene, limonene, β-myrcene and (+)-longifolene 0-100 mg / d. The invention can effectively lure the Huashan pine beetle, has a strong ability to lure adult hermaphrodites, has a simple preparation process and is convenient to use.

Description

technical field [0001] The invention relates to an insect attractant, in particular to a Huashan pine beetle attractant and a preparation method thereof. Background technique [0002] The Huashan pine beetle (Dendroctonus armandii Tsai&Li) is a unique species in my country, widely distributed in Shaanxi, Sichuan, Gansu, Hubei and Henan, etc., and is a destructive pioneer beetle in the Bashan forest area of ​​the Qinling Mountains. It mainly harms Huashan pine (Pinusarmandii Franch.) and Chinese pine ( P. tabuliformis Carr.), the average annual growth rate in Shaanxi is 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, ...
