Problems solved by technology

Many scholars have systematically and comprehensively elaborated and summarized the species, geographical distribution, bioecological characteristics, investigation and monitoring, forecasting models, occurrence and environment, control methods, management strategies, and comprehensive management of pine caterpillars in China. However, these discussions are based on Masson pine caterpillars, tabby pine caterpillars, larch caterpillars, and red pine caterpillars are the main ones, and there are few discussions on Yunnan pine caterpillars

Embodiment 1

[0038]The sex pheromone attractant core made in this example uses trans-5, cis 7-dodecadienol, trans 5, cis 7-dodecadiene acetate, trans 5, cis The chemical purity of 7-dodecadienal and cis-5, trans 7-dodecadiene acetate is 98%, and the purity of the stereoisomers is 95%. Weigh trans-5, cis-7-dodecadienol 1000 mg, trans-5, cis-7-dodecadiene acetate 500 mg, trans-5, cis-7-dodecadienal 100 mg, or Weigh trans-5, cis-7-dodecadienol 1000 mg, cis-5, trans 7-dodecadiene acetate 500 mg, trans-5, cis-7-dodecanal 100 mg, and The three ingredients are mixed uniformly to make a sex attractant. Then take the cuff-type composite rubber core carrier 2 (as shown in Figure 1) purchased on the market, where the composite rubber contains 30-70% (W / W) chlorinated butyl rubber and 70-30% natural rubber ; Take 20 μL of the prepared sex attractant 3 and add it dropwise to the composite rubber core carrier 2 prepared in step 2); then add antioxidants to the prepared attract core, and take butyl hydroxyan...

Embodiment 2

[0042] The sex pheromone attractant lure core 1 produced in this example uses trans-5, cis 7-dodecandienol, trans 5, cis 7-dodecadiene acetate, and trans 5, which are purchased on the market. The chemical purity of cis-7-dodecadienal and cis-5, trans-7-dodecadiene acetate is 98%, and the purity of the stereoisomers is 95%. Weigh trans-5, cis-7-dodecadienol 100 mg, trans-5, cis-7-dodecadiene acetate 50 mg, trans-5, cis-7-dodecadienal 10 mg, and The three ingredients are mixed uniformly to make a sex attractant. Then take the cuff-type composite rubber core carrier 2 (as shown in Figure 1) purchased on the market, where the composite rubber contains 30-70% (W / W) chlorinated butyl rubber and 70-30% natural rubber ; Take 20 μL of the prepared sex attractant and add it dropwise to the composite rubber core carrier 2 produced in step 2) to make the core 1 of Dendrolimus yunnanensis.

Abstract

The invention discloses a Yunnan Dendrolimus sex attractant attracting core, which is characterized by the following: comprising compounded rubber attracting core carrier, sex attractant dipped into attracting core carrier and carrene; allocating the sex attractant with 0. 1-50mg inverse 5, cis-7-lauric diene alcohol, 0. 1-15mg inverse 5, cis-7-lauric dienoic acetate or cis 5, invert-7-lauric dienoic acetate, 0. 1-10mg inverse 5, cis-7-lauric dienoic aldehyde; comprising antioxidant or / and ultraviolet light absorbent 2-hydroxyl group-4-methoxy benzophenone. This invention can decreases isomerization rate of adjoint diene pheromone in attracting core, which can make sex pheromone discharge slowly and evenly in the carrier.

Description

Technical field [0001] The invention relates to an attractant for monitoring and controlling pine caterpillars, in particular to an attractant for monitoring and controlling pine caterpillars by using sex pheromone and a preparation method thereof. Background technique [0002] Lasiocampidae (Lasiocampidae) belongs to Lepidoptera (Lepidoptera), including many major forest pests, among which some species of Dendrolimus are their representatives. There are more than 30 species of pine caterpillars in the world. Among the 27 species of pine caterpillars in China, there are 6 species that are seriously harmful and widely distributed, namely: Dendrolimus punctatus, D. superans, and D. superans. Pine caterpillar (D.tabulaeformis), Yunnan pine caterpillar (D.houi), red pine caterpillar (D.spectabilis) and Simao pine caterpillar (D.kikuchii). This kind of pests are the most serious forest pests in our country, with many species, wide distribution and strong fecundity. When a large amount...
