Embodiment 1

[0041] A compound insect sex pheromone for controlling rice field pests, the composition of which contains 2 parts of a first-class sex pheromone, 1 part of a second-class sex pheromone and 2 parts of a third-class sex pheromone, and its preparation method is as follows:

[0042] (1) Add cis-11-hexadecenal, cis-13-octadecenal, cis-9-hexadecenal and hexadecenal into a test tube to obtain a class of sex pheromones. Add cis 9 trans 11-tetradecadadiene acetate and cis 9 trans 12-tetradecadadiene acetate into the test tube to obtain the second type of sex pheromone. Add cis 7 cis 11 trans 13-hexadecadienal, cis 7 cis 11-hexadecadienal and cis 7-hexadecenoic acid into the test tube to obtain three types of sex pheromones.

[0043] Add a synergist of 15% of the total weight of the second type of sex pheromone to the second type of sex pheromone, and then mix 2 parts of the first type of sex pheromone, 1 part of the second type of sex pheromone and 2 parts of the third type of sex phe...

Abstract

The invention discloses a preparation method of compound insect sex pheromone for rice field pest control. The composite insect sex pheromone composition comprises sex pheromones I, sex pheromones IIand sex pheromones III, wherein the mass ratio of the first-class sex pheromones to the second-class sex pheromones to the third-class sex pheromones is (2-5) : (1-2) : (2-3); the preparation method comprises the following steps: (1) preparation of a composition reagent: mixing the synergist into a secondary sex pheromone solution under the conditions of standard atmospheric pressure and 20-25 DEGC, mixing the primary sex pheromone, the secondary sex pheromone and the tertiary sex pheromone in proportion, and performing standing treatment for later use; and (2) sequentially mixing an antioxidant and a light stabilizer in a certain proportion into the composition reagent, and uniformly mixing all the components to obtain the compound insect sex pheromone reagent. The composition reagent disclosed by the invention can be used for preventing and treating rice field pests, and has the advantages that three types of pests can be lured to gather at the same time, and the pest prevention andtreatment efficiency in a specific area is greatly improved.

Description

technical field [0001] The invention relates to the field of pest control reagents, more specifically, it relates to a preparation method of a compound insect sex pheromone used for the control of paddy field pests. Background technique [0002] Rice field pests have always been an important factor affecting the yield per mu of rice fields. With the development and progress of science and technology, the application of pheromones to control pests has become an important technology in the field of pest control. [0003] Sex pheromone pest control products generally include two components: lures and traps. Among them, lures are sex pheromones that attract specific types of pests, and traps are containers for holding sex pheromones. The working principle of this kind of product is: release high concentration of biomimetic synthetic odor unique to female pests through inducement, so as to attract male insects within a certain range around the trap to gather. By interfering with...
