Problems solved by technology

[0005] In January 2010, the applicant used the special lures imported from abroad to trap the bark beetles in the forests of my country, and found that the effect was not good, not as good as the bait wood
Because the environmental conditions and hosts of the Hengkeng beetle in my country are completely different from those in foreign countries, their semiochemical substances are also different, and some components (such as (1S,6R)-3-carene-10-ol) reported abroad It is not available in China, and we did not find the same composition in the hindgut volatiles of the Hengkeng beetle in Yunnan, my country, and the composition of foreign commercial lures is not disclosed

specific Embodiment approach

[0034] The Yunnan Hengkeng tip-cutting beetle attractant of the present invention is the result of two consecutive years of testing in the Beishan Forest Farm of Yuxi City, Yunnan Province. The purity and manufacturers of the compounds used are listed in Table 1. (Wherein, the sample purity in Table 1 is volume percent) (the number that does not have percentage sign behind the figure also still represents volume percent)

[0035] Put 40mL of the mixed solution into a 100mL slow-release bottle (produced by Sancheng Plastic Factory, Xiaodian District, Taiyuan City, Shanxi Province). The release rate of α-pinene is about 50mg / d. The cross-shaped trap is 81cm high and 37cm wide (Zhongjie Sifang, Beijing), and there is a plastic collection bottle at the bottom. The slow-release bottle is fixed on the lower part of the trap. The traps were hung between the Yunnan pine trees in the forest, with the bottom 1.5m above the ground and an interval of 40m.

Embodiment 1

[0036] Embodiment 1: In December 2010, a field test was carried out in Yuxi Beishan Forest Farm. According to the analysis of the hindgut chemical substances of the damaged and uninjured Pinus yunnanensis and the chemical substances in the hindgut of the cut tip beetle and the impact of the cut tip beetle on the horizontal pit The antenna potential response of different chemical substances is configured with 3 recipes, as shown in the table below. Wherein C is the commercial luring core of bark beetles in foreign horizontal pits, ABD is the formula of the present invention, and the release rate of A treatment is doubled to obtain E, and F is only hung with traps as a blank control. The ingredients and proportions of each formula are shown in Table 2. Each treatment was repeated 3 times, the investigation was performed every 5 days, and the traps were randomly exchanged.

Embodiment 2

[0043] Example 2: It was carried out in Yuxi Beishan Forest Farm from December 2011 to February 15, 2012. On the basis of the test in 2010, through research, the formulation of the lure was further improved, and a total of 6 formulations were designed, namely D and K , L, M, N and O, where D is the formula that was superior to foreign lures in 2010. In addition, U is the felling of Yunnan pine as a control. The composition and proportion of other treatments are shown in Table 2. Each treatment was repeated 5 times. Other conditions are with embodiment 1.

[0046] Note: U is the mildly damaged Yunnan pine as a control.

[0047] In Example 2, 315 female and 312 male beetles were lured, female (F=24.952; df=6, 28, P=0.0001), male (F=21.247; df=6, 28; P=0.0001). The results show that all new formulas have improved lure effect relative to the best formula and the victimized bait wood in 2010, wh...

Abstract

The invention discloses application of monoterpene and monoterpene alcohol as attractants of tomicus minor hartig consi and an attractant of tomicus minor hartig. One or more of the following components act as the application of the attractant of tomicus minor hartig consi: S-(-)-alpha-pinene, IR-(+)-alpha-pinene, myrcene, (+)-camphenee, (-)-camphene, alpha-terpinene, (+)-3-carnene, (1s)-(-)-beta-pinene, (-)-limonene, (+)-limonene, (-)-Myrtenol, (s)-cis-verbenol, (-)-trans-verbenol and cuparene.

Description

technical field [0001] The present invention relates to the application of terpene and monoterpene alcohol as the attractant of the bark beetle and the new composition and new formula of the attractant of the bark beetle. Background technique [0002] Minor Hartig (Tomicus.minor Hartig) is an important dry borer pest, which seriously damages many species of Pine. At present, the domestic research on the tip-cutting beetle of Hengkeng mainly focuses on biology, hazard characteristics, information chemicals and control technology. According to the applicant's investigation, the main measures to prevent and control bark beetles in Yunnan are as follows: ①Strengthen quarantine and strictly prohibit the transport of bark beetle trees. ② Clean up the moth-damaged wood. In order to prevent the spread of pests, all the damaged trees in the forest will be harvested, and under the supervision of technicians, they will be fumigated or burnt. ③Trap and kill with bait wood. In the ba...
