Problems solved by technology

Field trapping experiments showed that: meso barktenol (a mixture of (S)-(-)- and (R)-(+)-two isomers of barktenol) was effective for male and female bark beetle Adults have a strong ability to attract and aggregate; barktenol and 3-methyl-3-buten-1-ol have no synergistic and inhibitory effects on barktenol; α-pinene, β-pinene and P-cymene has no attractant effect on Larch beetle, but the mixture of the three has a certain inhibitory effect on the attractant activity of barculenol (Zhang et al., 2007)
In 2010, Song Liwen found in the forest bioactivity test of the larch octodent beetle: 1) 97%-(S)-(-)-barktenol and 97%-(S)-(+)-bark beetle II Enol mixtures exhibited strong attractant activity in Jingyuetan Park, Jilin Province; the two components alone had no attractant activity; 3-methyl-3-buten-1-ol had no synergistic or inhibitory effect on these two components active

preparation example Construction

[0039] The preparation method of the larch eight-toothed bark beetle repellent lure comprises: dissolving the larch eight-tooth bark beetle repellent in a solvent according to the above components or using it directly, and then dripping it with a pipette 12s black poly bag carrier.

[0040] Specific steps include:

[0041] (1) Dissolving the obtained larch bark beetle repellent 1) in a solvent; 2), 3) or 4) are weighed as they are, and set aside.

[0042] (2) Use a pipette to add the repellent prepared in step (1) dropwise to the absorbent cotton in the 12s black polyethylene plastic bag carrier.

[0043] The lure core made in step (2) is sealed with a sealing machine, and then can be sealed in a sample bag made of aluminum foil, and stored at low temperature for future use.

[0044] Preferably, the components of the larix bark beetle repellent are embodied in the following absolute amounts in each lure:

[0045] 1) trans verbenol (40 mg / bait), or

[0046] 2) cis-3-hexen-1...

Embodiment 1

[0075]The lure of the larix bark beetle repellent repellent is made by using trans-verbenaenol purchased on the market, and its chemical purity and stereoisomer purity are both greater than 97%. Weigh 40 mg of trans verbenol / each lure, and prepare this ingredient as a repellent. Then get the black polyethylene plastic bag that buys on the market and do carrier, with the repellent that makes, get 1000 μ L drop-wise in the absorbent cotton in the black polyethylene plastic bag carrier (the amount of single component in each polyethylene carrier is 40mg ), made into a repellent of larch octodon bark beetle. At the same time, the inhibitory effect of cis-verbenoenol and verbenone on the aggregation attractant of larch octodon beetle was studied in the forest. The method for preparing the repellent lures with these two components is the same as the method for preparing trans-verbenaenol above, and the loading amount of each repellent lure is 40 mg.

[0076] The prepared lures are...

Embodiment 2

[0090] The larch bark beetle repellent lure made in this embodiment adopts cis-3-hexen-1-ol, linalool or R-alpha-pinene purchased on the market, its chemical purity and stereoisometry The purity of the conformation is greater than 96%. Weigh cis-3-hexen-1-ol 2 g / each lure, linalool 2 g / each lure, R-alpha-pinene 2 g / each lure, and mix the three components Take one or several kinds to make repellent. Then take the polyethylene plastic bag carrier purchased in the market, use the prepared repellent, take 2200 μ L dropwise into the absorbent cotton of the polyethylene plastic bag carrier, and make the larch octodentate bark beetle repellent respectively.

[0091] The prepared lures are sealed and packaged with aluminum foil paper, and refrigerated at 4°C. If it is used in the field in different places, it is best to store and transport it under low temperature conditions.

[0092] At the same time, make the attractant lures for larch octodent beetle aggregation, containing (S)-...

Abstract

The invention relates to a repellent and a lure for Ips subelongatus Motschulsky and preparation methods thereof, belonging to the technical field of prevention and control of Ips subelongatus Motschulsky. The repellent comprises one or a mixture of more than two selected from the group consisting of trans-verbenol, cis-3-hexen-1-ol, linalool and R-alpha-pinene. The repellent provided by the invention has good release performance, repellent activity and stability and broad industrialization prospects; and since the preparation method for the repellent is simple, the repellent is especially applicable to large-area popularization in production, so mass prevention and mass control effects aiming at harm of Ips subelongatus Motschulsky are achieved. Combined use of the repellent and the lure is suitable for comprehensive prevention and control of Ips subelongatus Motschulsky in a place with a large occurrence area and complex topography and terrain, so Ips subelongatus Motschulsky push-and-pull technology is applied to prevention and control of the harm of Ips subelongatus Motschulsky, and good economic benefits, social benefits and ecological benefits are obtained.

Description

technical field [0001] The invention relates to a larch eight-tooth bark beetle repellent, a lure and a preparation method thereof, which are used for repelling larix eight-tooth bark beetle population aggregation, and belong to the technical field of larix eight-tooth bark beetle prevention and control. Background technique [0002] Larch eight-toothed beetle (Ips subelongatus Motschulsky) belongs to Coleoptera (Coleoptera), Weevil family (Curculionidae), Scolytinae subfamily (Scolytinae), tooth beetle (Ips). It mainly affects larch (Larix spp.), and is also found in red pine and spruce. As the pioneer species of borer pests in northern larch artificial timber forests, this insect species is often rampant, invading healthy or semi-healthy standing trees, and has become a major threat in the current management of larch plantation forests. In the Northeast of my country, the hosts of larix octodentum mainly include Larix gmelinii Kuzen., L. olgensis Henry, L. principis-ruppr...
