Embodiment 1

[0030] From July 20th to 28th, 2000, the moth-trapping effect of lures with different compositions on Dendrolimus densiflora was tested in Zhoujiadian Forest Farm, Fuxin County, Liaoning Province. The three components of sex pheromone are cis-5, trans 7-dodecadienol (Z5, E7-12: OH), cis 5, trans 7-dodecadiene acetate (Z5, E7-12: The chemical purity of OAc) and cis-5, trans 7-dodecadiallylate (Z5, E7-12: OPr) is 95%, and the stereoisomeric purity is 96%. The three components were dissolved in hexane at the dosages shown in Table 1, and dropped onto the septum of the sleeve rubber stopper with a microsyringe. After the hexane is volatilized, 200 microliters of dichloromethane are added dropwise in two portions, so that the sex pheromone component penetrates into the inside of the septum of the sleeve rubber stopper. The prepared lure is stored in the freezer at -20℃ for later use. When trapping moths in the field, fix the trap core with a thin iron wire in the boat trap (42cm×22cm),...

Embodiment 2

[0042] From July 24 to 30, 2001, an experiment was carried out at Zhoujiadian Forest Farm in Fuxin County, Liaoning Province to determine the optimal ratio of the three components of Dendrolimus densiflora sex pheromone. The three components of sex pheromone are cis-5, trans 7-dodecadienol (Z5, E7-12: OH), cis 5, trans 7-dodecadiene acetate (Z5, E7-12: The chemical purity and stereoisomeric purity of OAc) and cis 5, trans 7-dodecadiallylate (Z5, E7-12: OPr) are the same as those in Example 1. Prepare the lure core according to the dosage shown in Table 2. The lure core I-VI is to keep the content of Z5, E7-12: OH (500 micrograms) and Z5, E7-12: OAc (15 micrograms) in the core unchanged, and then Add the following doses of Z5, E7-12: OPr to each type of lure: 0(I), 0.2(II), 15(III), 25(IV), 125(VI) micrograms, in lure VII The three components are 167 micrograms and 167 micrograms respectively. Each type of lure is set up 4 times repeatedly. The manufacturing procedure of the lure c...

Embodiment 3

[0055] Field trials were conducted at Zhoujiadian Forest Farm in Fuxin County, Liaoning Province from July 24 to 30, 2002 to determine whether the different Z5, E7-12: OAc content in the lure had an effect on the moth trapping effect. The three components of sex pheromone cis-5, trans 7-dodecadienol (Z5, E7-12: OH), cis 5, trans 7-dodecadiene acetate (Z5, E7-12 : OAc) and cis 5, trans 7-dodecadiallyl ester (Z5, E7-12: OPr) have the same chemical purity and stereoisomeric purity as in Example 1. The lure core was prepared according to the dosage shown in Table 3. The lure core I-IV kept the content of Z5, E7-12: OH (500 micrograms) and Z5, E7-12: OPr (125 micrograms) in the core, respectively. Then add the following doses of Z5, E7-12: OAc: 3(I), 15(II), 75(III), 375(IV) micrograms to each type of lure core. The dosage of each component of lure type V and VI is the same as that of type I and II, but the stereoisomeric purity is lower, 70%. Repeat 4 for each type. The manufacturing ...

Abstract

The present invention relates to one kind of red bordered white moth pheromone inducer, which has sleeve type rubber stopper carrier and hexane solution of the red bordered white moth pheromone dropped to the carrier. The said red bordered white moth pheromone includes cis-5 trans-7 dodecadienoic alcohol, cis-5 trans-7 dodecadienoic acetate and cis-5 trans-7 dodecadienoic propionate. The present invention also relates to the use of the red bordered white moth pheromone inducer. The inducer may be used in monitoring, preventing and trapping and killing red bordered white moth in various areas and countries.

Description

Technical field [0001] The invention relates to an insect sex pheromone lure, in particular to a dendrolimus densiflora sex pheromone lure and its use. Background technique [0002] Population monitoring and forecasting of forest pests is an extremely important part of pest control. The use of sex pheromone (also known as sex attractant) for monitoring can overcome the limitations of direct manual investigation caused by the large forest distribution, and the variability of topography and terrain. This method can make timely and accurate forecasts of pests, and is beneficial to effectively carry out biological or chemical control of pests, so as to control pests in the early stage of occurrence to minimize losses. In addition, because this method has the advantages of cheapness and low cost, it has received great attention at home and abroad. [0003] In Michigan, USA, 25,000 gypsy moth sex pheromone traps were used to monitor pests. Based on the trapping results, the trapping am...
