Embodiment 1

[0030] From July 20 to 28, 2000, the moth-attracting effect test of lures with different components on the red pine caterpillar was carried out in Zhoujiadian Forest Farm, Fuxin County, Liaoning Province. The three components of sex pheromones are 5, trans 7-dodecadienol (Z5, E7-12: OH), cis 5, trans 7-dodecadienyl acetate (Z5, E7-12: OAc) and cis 5, trans 7-dodecadieacrylate (Z5, E7-12: OPr) had a chemical purity of 95%, and a stereoisomeric purity of 96%. These three components were dissolved in hexane according to the doses shown in Table 1, and dripped onto the septum of the cuff-type rubber stopper with a micro-syringe. After the hexane volatilized, 200 microliters of dichloromethane was added dropwise twice, so that the sex pheromone component penetrated into the septum of the cuff-type rubber stopper. The prepared lures are stored in a freezer at -20°C for future use. When trapping moths in the field, fix the lure core in a boat-shaped trap (42cm×22cm) with thin wire,...

Embodiment 2

[0034] From July 24th to 30th, 2001, an experiment was carried out in Zhoujiadian Forest Farm, Fuxin County, Liaoning Province to determine the optimal moth-attracting ratio of the three components of the sex pheromone of the red pine caterpillar. The three components of sex pheromones are 5, trans 7-dodecadienol (Z5, E7-12: OH), cis 5, trans 7-dodecadienyl acetate (Z5, E7-12: OAc) and cis 5, trans 7-dodecadieacrylate (Z5, E7-12: OPr) had the same chemical and stereoisomeric purity as in Example 1. Prepare lures by dosage shown in table 2, lures I-VI are to keep Z5 in the lure respectively, E7-12: OH (500 micrograms) and Z5, E7-12: OAc (15 micrograms) content constant, then The following doses of Z5, E7-12 were added to each type of lure: OPr: 0(I), 0.2(II), 15(III), 25(IV), 125(VI) micrograms in lure VII The three components are 167 micrograms, 167 micrograms and 167 micrograms respectively. Four lures of each type were set up repeatedly. The making procedure of lure core,...

Embodiment 3

[0038] From July 24 to 30, 2002, a field experiment was conducted in Zhoujiadian Forest Farm, Fuxin County, Liaoning Province to determine whether different Z5, E7-12: OAc contents in lure cores had an effect on moth lure. The three components of sex pheromones are 5, trans 7-dodecadienol (Z5, E7-12: OH), cis 5, trans 7-dodecadienyl acetate (Z5, E7-12: OAc) and cis 5, trans 7-dodecadieacrylate (Z5, E7-12: OPr) had the same chemical and stereoisomeric purity as in Example 1. Prepare lures by dosage shown in table 3, lures I-IV are to keep Z5 respectively in lures, E7-12: OH (500 micrograms) and Z5, E7-12: OPr (125 micrograms) content constant, The following doses of Z5, E7-12: OAc were then added to each type of lure: 3(I), 15(II), 75(III), 375(IV) micrograms. The doses of the components of lure types V and VI are the same as those of types I and II respectively, but the stereoisomer purity is lower, which is 70%. Set 4 replicates of each type. The making procedure of lure c...

Abstract

The invention relates to a red pine caterpillar sex pheromone lure core. A cuff-type rubber stopper is used as a carrier, and a hexane solution with a red pine caterpillar sex pheromone is dropped onto the carrier. The red pine caterpillar sex pheromone comprises: cis 5 , trans-7-dodecadienol, cis-5, trans-7-dodecadiene acetate and cis-5, trans-7-dodecadienoate. The present invention also relates to the use of the described red pine caterpillar sex pheromone lure core, which can be used for monitoring the pest and preventing and smelting through a large number of trapping and smelting in areas or countries where the red pine caterpillar occurs; Check for invasiveness of the species.

Description

technical field [0001] The invention relates to an insect sex pheromone lure, in particular to a red pine caterpillar sex pheromone lure and its application. Background technique [0002] Population monitoring and forecasting of forest pests is an extremely important part of pest control. The use of sex pheromones (also known as sex attractants) for monitoring can overcome the limitations of manual direct surveys caused by the large forest distribution area, terrain and terrain. This method can timely and accurately forecast the pests, and is beneficial to effectively carry out biological control or chemical control of the pests, so as to control the pests in the early stage of occurrence and minimize losses. In addition, because this method has the advantages of convenient operation and low cost, it has received great attention at home and abroad. [0003] 25,000 gypsy moth sex pheromone traps were used in Michigan, USA to monitor pests, and the trapping amount and damage...
