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 a cutworm attractant composition and its application, which belong to the technical field of insect sex pheromone preparation. The attractant composition of cutworm includes sex pheromone of cutworm and synergist, and the weight ratio of cutworm sex pheromone to synergist is 1: (0.5~100), wherein the main component of cutworm sex pheromone is cis-7-tetradecene acetate, cis-5-tetradecene acetate and trans-5-tetradecene acetate, synergist selected from plant volatile substances: 1-hexanol , phenylacetaldehyde, cis-3-hexene-1-ol, heptanal, and linalool, or one or more of them. The attractant composition of the Chinese cutworm provided by the invention can be accurately applied to insect situation monitoring, mass trapping and interfering mating of the Chinese cutworm, and is of great significance for the comprehensive management of the Chinese cutworm.

Description

technical field [0001] The invention relates to the technical field of preparation of insect sex pheromones, in particular to a cutworm attractant composition and application thereof. Background technique [0002] Xestia c-nigrum (Linnaeus), belonging to Lepidoptera of Lepidoptera and Noctuidae of family Noctuidae, is an important root-cutting pest in agriculture and grassland. The larvae have feigned death, are nocturnal and have strong concealment. Distributed all over the world, it is seriously harmful in the United States, Japan and other countries. It can harm tobacco, tomato, cabbage, grapes and other food habits. In my country, it mainly harms more than 100 kinds of plants such as food crops, cotton, tobacco, vegetables, and medicinal plants. , known to harm the seedlings of a variety of plants, and its geographical distribution spreads all over the country. At present, the methods of its control mainly include spraying chemical agents, trapping and killing adults. ...
