Problems solved by technology

Although sex pheromones have the advantages of strong selectivity, trace efficiency, and environmental friendliness, they can only trap and kill male individuals of the same species, and can only achieve better results for species with a single mating habit, and lose when the population density of wild female moths is high. effect

Embodiment 1

[0025] The Y-type olfactometer of embodiment 1 single-component synergist is measured

[0026] Preparation of a single dose of plant-derived volatiles: each compound was prepared in three concentrations of 0.1, 1, and 10 μg / μl using n-hexane as a solvent, and n-hexane was used as a control.

[0027] The sensitivities of cutworms to various reagents were measured by "Y" type olfactometer. In a room with clean air at 25°C, a relative humidity of about 70%, and a 3cm*20cm "Y" type olfactometer for biological determination. Take 10 μl of the single-component compound of the synergist and drop it on a filter paper strip, place it in one side arm of a Y-shaped olfactometer, and put an equal amount of n-hexane in the other side arm as a control. After each group was repeated, the positions of the test group and the control group were reversed to avoid experimental errors. After each test, a new filter paper strip was replaced, each reagent was repeated 3 times, and a clean "Y" tube...

Embodiment 2

[0035] Embodiment 2 Synergistic effect of different formula synergists on sex pheromone of cutworm

[0036] 1-hexanol, phenylacetaldehyde, cis-3-hexen-1-ol, heptanal, linalool and cutworm sex pheromone were prepared into 500 μg / μL n-hexane solutions. Among them, the sex pheromone of the cutworm is 9 parts of cis-7-tetradecene acetate, 0.8 part of cis-5-tetradecene acetate and 0.2 part of trans-5-tetradecene acetate. Mix the proceeds.

[0037] Use a 200 μL pipette gun to draw a certain amount of each synergist component solution and the cutworm sex pheromone solution and mix evenly to obtain the cutworm plant-derived pheromone mixture. The composition of the attractant composition is shown in Table 1.

[0038] Use a 200 μL pipette gun to draw 200 μL of the cutworm attractant composition or the sex pheromone of the cutworm and drop it on the septum of the rubber stopper cleaned with n-hexane. After the n-hexane volatilizes, drop 1 ml of dichloromethane in portions Add, after ...

Abstract

The invention discloses Xestia c-nigrum attractant composition and an application thereof and belongs to the technical field of preparation of insect sex pheromones. The Xestia c-nigrum attractant composition is prepared from a Xestia c-nigrum sex pheromone and a synergist in a weight ratio being 1: (0.5-100), wherein the main ingredients of the Xestia c-nigrum sex pheromone are cis-7-tetradecenyl acetate, cis-5-tetradecenyl acetate and trans-5-tetradecenyl acetate, and the synergist is one or more of the following plant volatile substances: 1-hexanol, phenylacetaldehyde, cis-3-hexen-1-ol, heptaldehyde and linalool. The Xestia c-nigrum attractant composition can be applied to condition prediction, mass trapping and mating disruption of Xestia c-nigrum accurately and has great significance in comprehensive treatment of the Xestia c-nigrum.

Description

Technical field [0001] The present invention relates to the technical field of insect sex pheromone preparation, and in particular to a cutworm attractant composition and its application. Background technique [0002] Xestia c-nigrum (Linnaeus), belonging to the order Lepidoptera and the family Noctuidae, is an important root-cutting pest of agriculture and grasslands. The larvae are capable of suspended animation, lie dormant during the day and emerge at night, and are highly concealed. Distributed all over the world, it is very harmful in the United States, Japan and other countries. It can harm tobacco, tomatoes, cabbage, grapes, etc. It has a wide range of food habits. In my country, it mainly harms food crops, cotton, tobacco, vegetables, medicinal plants, etc. and harms more than 100 kinds of plants. , known for harming seedlings of a variety of plants, is distributed geographically across the country. At present, the main methods for its control include spraying chem...
