Embodiment Construction

[0022] The present invention will be specifically introduced below in conjunction with specific embodiments.

[0023] 1. Composition of sex pheromone composition

[0024] The standard compounds used in the test are:

[0025] (1) cis 9, trans 11-tetradecadiene acetate;

[0026] (2) Tetradecenal: cis 9-tetradecenal, trans 9-tetradecenal, cis 11-tetradecenal, trans 11-tetradecenal, cis 9, trans 11 -Tetradecadienal, trans 9, trans 11-tetradecadienal, cis 9, cis 11-tetradecadienal, trans 9, cis 11-tetradecadienal.

[0027] The purity of these standard compounds is higher than 99%.

[0028] 2. Solvent

[0029] Redistilled n-hexane and redistilled dichloromethane.

[0030] 3. Preparative pheromone composition

[0031] Cis 9, trans 11-tetradecadienyl acetate (referred to as A) and tetradecenal (referred to as B) can be mixed in many ways. In this example, we first dissolve the two separately In the redistilled dichloromethane (or redistilled n-hexane), it is all configured to a...

Abstract

The present invention discloses a prodenia litura sex pheromone composition and a prodenia litura sex pheromone lure, wherein the prodenia litura sex pheromone composition comprises two components such as cis-9,trans-11-tetradecadienyl acetate and tetradecenal according to a mass ratio of 50:1-1:50, and the prodenia litura sex pheromone lure comprises the prodenia litura sex pheromone composition and a releaser for holding and slowly releasing the prodenia litura sex pheromone composition. According to the present invention, the prodenia litura sex pheromone composition and the prodenia litura sex pheromone lure have strong specificity for male prodenia litura, and do not trap and kill female prodenia litura and other insects; and with the prodenia litura sex pheromone composition and the prodenia litura sex pheromone lure, the high-incidence season of the pest generation can be effectively monitored, the blind pesticide spraying can be avoided, the good prevention control effect is provided, and the natural enemies of pests can be effectively protected and used.

Description

technical field [0001] The invention relates to a substance for preventing and controlling Spodoptera litura, in particular to a sex pheromone composition of Spodoptera litura and a lure made of the sex pheromone composition, and belongs to the technical field of biological control of Spodoptera litura. Background technique [0002] Spodoptera litura (Fabricius) belongs to Lepidoptera Noctuidae, is a worldwide distribution of polyphagous important agricultural pests, distributed from 40°N to 57°N, and from 35°S to 40°S. There are records of damage in Asia, North America, Europe, Australia and Africa, mainly harming vegetables, cotton, peanuts, tobacco, corn, soybeans and other 138 species of 108 genera in 35 families, especially vegetables. [0003] At present, the main method of controlling Spodoptera litura is still the use of chemical pesticides, but the extensive use of chemical pesticides over the years has resulted in the reduction of the number of natural enemies, the...
