Problems solved by technology

The species of pine caterpillars that have clarified the components of sex pheromones, such as masson pine caterpillars, Simao pine caterpillars and larch caterpillars, have strong species specificity due to the differences in composition and proportion of their components, so different species Sex pheromone lures for pine caterpillars cannot be used universally

preparation example Construction

[0060] The preparation method of the above-mentioned pine caterpillar attractant lure core of the present invention includes: dissolving the pine caterpillar attractant in a solvent according to the above-mentioned composition and ratio, and then dripping it onto the septum of the sleeve-type composite rubber stopper with a syringe or Inside a polyethylene plastic tube.

[0061] Specific steps include:

[0062] (1) Prepare the sex attractant of Pinus tabulaeformis according to the following composition and ratio:

[0063] 1) cis 5, trans 7-dodecadiene acetate, 35-40%;

[0064] 2) cis 5, trans 7-dodecadienol, 35-40%;

[0065] 3) cis 5, trans 7-dodecadieacrylate, 2-18%;

[0066] 4) cis-5-dodecene acetate, 14-1%;

[0067] 5) cis-5-dodecenol, 14-1%;

[0068] Above percentage is that this compound accounts for the weight percent of attractant, mixes evenly according to above-mentioned proportion, for subsequent use;

[0069] (2) Dissolving the above-mentioned pine caterpillar...

Embodiment 1

[0083] The sex pheromone attractant lure core made in this embodiment adopts commercially available cis 5, trans 7-dodecadienol, cis 5, trans 7-dodecadienyl acetate, cis 5, trans 7 - dodecadienoate, cis-5-dodecenol and cis-5-dodecenyl acetate with a chemical purity of 95% and a stereoisomeric purity of 91%. Weigh cis 5, trans 7-dodecadienyl acetate 3 mg / each lure, cis 5, trans 7-dodecadienol 2.9 mg / each lure and cis 5, trans 7-deca Dicarbadiacrylate 1.2mg / each lure, cis-5-dodecenyl acetate 0.2mg / each lure and cis-5-dodecenol 0.3mg / each lure, the five The ingredients are mixed uniformly to make a sex attractant. Then get the cuff type compound rubber stopper carrier that buys on the market, this compound rubber contains the chlorinated butyl rubber of 30~70% (W / W) and the natural rubber of 70~30%; The sex attractant that will make is dissolved in In n-hexane, the concentration is 100 μg / μl, dropwise added to the composite rubber stopper (the amount of 5 components in each rub...

Embodiment 2

[0087]This embodiment makes sex pheromone attractant lure core, adopts cis 5, trans 7-dodecadienol, cis 5, trans 7-dodecadienyl acetate, cis 5, trans 7 - Dodecadienoate, cis-5-dodecenol and cis-5-dodecenyl acetate with a chemical purity of 95% and a stereoisomeric purity of 91%. Weigh cis 5, trans 7-dodecadienyl acetate 2 mg / each lure, cis 5, trans 7-dodecadienol 2 mg / each lure, cis 5, trans 7- Dodecadiacrylate 0.7mg / each lure, cis-5-dodecenyl acetate 0.5mg / each lure and cis-5-dodecenol 0.5mg / each lure, will The five ingredients are mixed evenly to make a sex attractant. Then take the cuff-type composite rubber stopper purchased on the market as a carrier, use the prepared sex attractant, and add 100 μL dropwise to the septum of the cuff-type composite rubber stopper (the dripping amount of 5 components on each compound rubber stopper septum) 2mg: 2mg: 0.7mg: 0.5mg: 0.5mg); then add antioxidants to the prepared lures, take 20 μL of butyl hydroxyanisole or 2,6-di-tert-butyl p...

Abstract

The invention relates to a sex attractant and a trapping core for Dendrolimus tabulaeformis and a preparation method of the trapping core. The attractant comprises the following components in percentage by weight: 35-40% of cis-5, trans-7 dodecadiene acetate, 35-40% of cis-5, trans-7 codlemone, 2-18% of cis-5, trans-7 dodecadiene propionate, 14-1% of cis-5 dodecene acetate and 14-1% of cis-5 lanolin alcohol. The prepared sex attractant is directly dropwise added to a diaphragm of a cuff type compounded rubber cork or a polyethylene pipe to prepare the trapping core for Dendrolimus tabulaeformis, and an antioxidant and an ultraviolet adsorbent are added when the trapping core is prepared. The attractant has the advantages of sensitivity, high efficiency, long duration, low price and the like, can be used for population monitoring and a great deal trapping and killing as well as prevention and control of Dendrolimus tabulaeformis and accurately predicting the incidence density of descendant population, and has good economic benefits and ecologic benefits.

Description

technical field [0001] The invention relates to a sexual attractant and lure core for pine caterpillars and a preparation method thereof, which are used for population monitoring and trapping of pine caterpillars, and belong to the technical field of monitoring and prevention of pine caterpillars. Background technique [0002] Lepidoptera (Lepidoptera) Lepidoptera (Lasiocampidae) includes many important species of forest leaf-eating pests, among which the genus Dendrolimus is a typical representative. There are more than 30 species of pine caterpillars in the world. Among the 27 species of pine caterpillars distributed in China, 6 species are seriously harmful and widely distributed, namely: Dendrolimus tabulaeformis, D. punctatus, larch Caterpillar (D. superans), Yunnan pine caterpillar (D. houi), red pine caterpillar (D. spectabilis) and Simao pine caterpillar (D. kikuchii). This kind of pest has a very strong fecundity. When a large number of them are rampant, all the ne...
