Embodiment 1

[0016] Extraction of sex pheromone from the vermilion moth

[0017] Using headspace adsorption method and gonad extraction method to extract sex pheromones from unmated females of Trichoma vermilion with different ages and different times of entering the photoperiod, and detect them by gas chromatography-mass spectrometry and insect antennae potential measurement The system test shows that the sex information of the vermilion moth is composed of cis-9-hexadecenal and (Z,Z,Z)-9,12,15-octadecatrienal.

Embodiment 2

[0019] Preparation of Sex Pheromone Lures for Trichomonas vermilion

[0020] At room temperature, first mix 10 μl of cis-9-hexadecenal and 10 μl of (Z,Z,Z)-9,12,15-octadecatrienal into 980 μl of In the n-hexane solution, a mixed solution of two sex pheromones with a mass ratio of 1:1 is formed; secondly, the mixed solution containing the sex pheromone of Vermilion Trichodidae is added dropwise on the cotton sliver lure, until the mixed solution containing Vermilion Trichodia moth After the n-hexane in the sex pheromone mixture volatilizes, the lure containing the vermilion trichophyll moth attractant is prepared; finally, the prepared lure is put into an aluminum foil and sealed, and refrigerated at -20°C.

Embodiment 3

[0022] Trapping effect of sex pheromone in the vermilion moth in the wild

[0023] Set the following 8 lures:

[0024] A. Add 10 microliters of cis-9-hexadecenal to 990 microliters of n-hexane solution, add the mixed solution dropwise to the cotton sliver lure, and after the n-hexane volatilizes, the vermilion hair containing lures for moth attractants;

[0025] B. Add 10 microliters of (Z,Z,Z)-9,12,15-octadecatrienal to 990 microliters of n-hexane solution, and add the mixture dropwise to the cotton sliver lure, wait until After the normal hexane volatilizes, the lure core containing the vermilion trichod moth attractant is produced;

[0026] C. Add 10 microliters of trans-9-hexadecenal to 990 microliters of n-hexane solution, add the mixed solution dropwise to the cotton sliver lure, and after the n-hexane volatilizes, the vermilion hair lures for moth attractants;

[0027] D, add 10 microliters of cis-9-hexadecenal and 10 microliters of (Z, Z, Z)-9,12,15-octadecatrienal...

Abstract

The invention provides a sex pheromone for controlling phauda flammans walker and a preparation method of a sex pheromone lure. The sex pheromone for controlling the phauda flammans walker is preparedfrom cis-9-hexadecenal and (Z,Z,Z)-9,12,15-octadecatrienal in a mass ratio being 1:1. The preparation method of the sex pheromone lure comprises following steps: firstly, 10 microlitres of cis-9-hexadecenal and 10 microlitres of (Z,Z,Z)-9,12,15-octadecatrienal are blended in 980 microlitres of a hexane liquor at room temperature, and a mixed liquor with the mass ratio of the two sex pheromones being 1:1 is obtained; then the mixed liquor containing the sex pheromone for controlling the phauda flammans walker is dropwise added to a cotton sliver lure, and after n-hexane in the mixed liquor containing the sex pheromone for controlling the phauda flammans walker is volatilized, the lure containing a phauda flammans walker luring agent is prepared; finally, the prepared lure is sealed in aluminum foil and refrigerated at subzero 20 DEG C. The sex pheromone for controlling the phauda flammans walker is high in specificity, has obvious trapping effect on the phauda flammans walker outdoorsand is stable in effect.

Description

technical field [0001] The invention belongs to the technical field of preparation of insect sex pheromones, and in particular relates to a preparation method of sex pheromones and lures used for preventing and controlling the vermilion hairy moth. Background technique [0002] Phauda flammans Walker (Lepidoptera: Lepidoptera: Zygaenidae) is an important defoliator on banyan trees. In recent years, intermittent outbreaks have occurred in my country's Guangxi, Guangdong, Fujian, and Hainan, as well as India, Vietnam, and Thailand, seriously affecting the living environment, urban landscape, image, and ecological benefits. At present, chemical control is still the main method for the control of the vermilion hairy moth, but the hosts it damages are often planted on both sides of the road or in the park with a lot of traffic. There are problems such as resistance to insecticides, killing natural enemies by mistake and polluting the environment. Biological control is an altern...
