Problems solved by technology

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. Problems such as drug resistance, manslaughtering of natural enemies and environmental pollution of the hairy moth

Embodiment 1

[0016] Extraction of sex pheromone of Vermillion moth

[0017] The headspace adsorption method and gonadal extraction method were used to extract the sex pheromone of the unmated females of the Vermillion moth at different ages and entering the photoperiod at different times. The detection was carried out by gas chromatography-mass spectrometry and the insect antenna potential measurement System testing showed that the sex information of Vermillion Moth is composed of cis-9-hexadecenal and (Z,Z,Z)-9,12,15-octadecenal.

Embodiment 2

[0019] Preparation of the sex pheromone lure of P. versicolor

[0020] At room temperature, first mix 10 microliters of cis-9-hexadecenal and 10 microliters of (Z,Z,Z)-9,12,15-octadecenal to 980 microliters In the n-hexane solution, a mixture of two sex pheromones with a mass ratio of 1:1 is formed; secondly, the mixed liquid containing the sex pheromone of the vermillion moth is added dropwise to the cotton sliver lure. After the n-hexane in the sex pheromone mixture is volatilized, a lure containing vermillion moth attractant is prepared; finally, the prepared lure is sealed in aluminum foil, and stored at -20°C.

Embodiment 3

[0022] The trapping effect of the sex pheromone of Vermillion moth

[0023] Set the following 8 kinds of lures:

[0024] A. Add 10 microliters of cis-9-hexadecenal to 990 microliters of n-hexane solution, and add the mixed liquid dropwise to the tampon lure core. After the n-hexane volatilizes, it will produce vermilion hair The lure of the moth attractant;

[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 tampon lure. After the volatilization of n-hexane, the lure core containing vermillion moth attractant is prepared;

[0026] C. Add 10 microliters of trans-9-hexadecenal to 990 microliters of n-hexane solution, and add the mixed liquid dropwise to the tampon lure core. After the n-hexane volatilizes, the product contains vermilion hair The lure of the moth attractant;

[0027] D, add 10 microliters of cis-9-hexadecenal and 10 microliters of (Z,Z,Z)-9,12,15-octadecenal to 980 microliters of ...

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 insect sex pheromone preparation, and in particular relates to a method for preparing a sex pheromone for preventing and controlling the vermilion moth and its lure core. Background technique [0002] Phauda flammans Walker (Lepidoptera: Zygaenidae) is an important leaf-eating pest on banyan trees. In recent years, there have been intermittent outbreaks in Guangxi, Guangdong, Fujian and Hainan in my country, as well as in countries such as India, Vietnam and Thailand, which have seriously affected the human settlement environment and urban landscape, image and ecological benefits. At present, the prevention and control of Vermillion Moth is still based on chemical control, but the host that it damages is often planted on both sides of roads or parks with heavy traffic. The large-scale use of chemical agents seriously threatens human health and can easily cause vermilion. The hair spot moth has problems such a...
