Embodiment 1
[0036] Experiment 1 was carried out in Dalishu Village, Qujing in January 2011. According to the analysis results of host volatiles and bark beetle pheromones, three kinds of attractant formulas (numbered A, B, C, respectively) were configured, and set A blank control (No. D) that only hangs traps. The specific proportioning of formula is shown in Table 2.
[0037] 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 trap is 81cm high and 37cm wide (Zhongjie Sifang, Beijing). There is a plastic collection bottle at the bottom, and the slow-release bottle is fixed at the bottom 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. Each treatment was repeated 5 times, the amount of trapping was investigated every 5 days, and the traps were ran...
Embodiment 2
[0044] In January 2012, the test trial was continued in Dalishu Village, Qujing. There are 9 treatments in total, all of which are attractant formulas, and the numbers are C, E, F, G, K, L, M respectively. Wherein formula C is the optimal formula screened out from embodiment 1, is treated as contrast in this test; Other formulas are new formulas formed on the basis of C formula, and its composition and ratio are shown in Table 3. Each treatment was repeated 5 times, and the implementation method in the forest was the same as in Example 1.

[0046]
[0047] Such as figure 2 , image 3 and Figure 4 As shown, the experiment attracted a total of 335 and 246 male and female beetles, respectively. There were significantly more male and female beetles of yunnanensis lured by treatment C, E, F and G than five treatments H, I, J, K and L (female F=7.890, df=8, 36, P=0.0001, see figure 2 ; male F=24.788, d...

Abstract
The invention discloses an attractant of tomicus yunnanensis. The attractant comprises one or more of the following components: S-(-)-alpha-pinene, 1R-(+)-alpha-pinene, myrcene, (+)-camphene, (-)-camphene, alpha-terpinene, (+)-3-carene, (1s)-(-)-beta-pinene, (-)-limonene, (+)-limonene, (-)-Myrteneol, (s)-cis-verbenol, (-)-trans-verbenol and Cuparene. According to the attractant disclosed by the invention, the attractant containing a host and polypide volatile matter is utilized for attract tomicus yunnanensis massively, so that the tomicus yunnanensis is gathered in a certain device and then is killed; the attractant has the advantages of low cost, high efficiency, complete environmental friendliness, safety to people and livestock, incapability of generating drug resistance to insects and the like, so that the traditional passive chemical prevention and treatment can be replaced by active biological prevention and treatment; meanwhile, the aims of monitoring and forecasting the forestryinsect pests can be achieved according to the amount of tomicus yunnanensis in the attractant.
Description
technical field [0001] The present invention relates to the application of terpene and monoterpenealcohol as the attractant of the cut beetle of Yunnan and a kind of attractant of the cut beetle of Yunnan. Background technique [0002] Tomicus yunnαnensis Kirkendall and Faccoli (Tomicus yunnαnensis Kirkendall and Faccoli) is an important stem-boring pest, which mainly occurs in Yunnan and Sichuan in China and harms many species of Pinus. But so far, there are few domestic and foreign research literatures on S. yunnanensis, and they mainly focus on biology and host selection. According to the applicant's investigation, the main measures to prevent and control bark beetles in Yunnan are as follows: ①Strengthen quarantine. It is strictly forbidden to transport moth-infested trees to prevent the affected seedlings from spreading from the infected area to other places. ② Clean up the moth-damaged wood. In order to prevent the spread of pests, all the damaged trees in the fore...
