Problems solved by technology

Because the economic value per unit area of ​​grassland is low, the large-scale use of chemical pesticides often outweighs the gains
Secondly, the extensive use of chemical pesticides will cause the deterioration of the grassland ecological environment and endanger the development of grassland animal husbandry.

Embodiment 1

[0029] Embodiment 1, preparation of meadow moth sex attractant

[0030] The following meadow moth sex attractant A to meadow moth sex attractant G are all composed of trans 11-tetradecenyl acetate, trans 11-tetradecenal and n-tetradecyl alcohol, and the mass ratio of the three components is as follows:

[0031] Meadow moth sex attractant A: trans 11-tetradecenyl acetate: trans 11-tetradecenal: n-tetradecyl alcohol = 1:1:1.

[0032] Meadow moth sex attractant B: trans 11-tetradecenyl acetate: trans 11-tetradecenal: n-tetradecyl alcohol = 1:4:5.

[0033] Meadow moth sex attractant C: trans 11-tetradecenyl acetate: trans 11-tetradecenal: n-tetradecyl alcohol = 3:3:1.

[0034] Meadow moth sex attractant D: trans 11-tetradecenyl acetate: trans 11-tetradecenal: n-tetradecyl alcohol = 7:5:9.

[0035] Meadow moth sex attractant E: trans 11-tetradecenyl acetate: trans 11-tetradecenal: n-tetradecyl alcohol = 5:1:1.

[0036] Meadow moth sex attractant F: trans 11-tetradecenyl acetate:...

Embodiment 2

[0039] Embodiment 2, application and effect evaluation of meadow borer sex attractant

[0040] 1. Indoor Biotest

[0041]The activity of the sex-attractant is mainly determined by a series of sexual behavior responses of the male. If the sex-attractant is active, the male will have reactions such as swinging antennae, fluttering wings frequently, tilting the abdomen and even stretching out the gripper. In this experiment, the following indicators were selected for indoor biometrics: excitement (the antennae of the male moth frequently swing, and the forefoot combs the antennae continuously); take-off (flying against the wind along the sex pheromone air trail); search for the release source (circling around the release source, Landing at or near the source of release); pre-mating (male spreads wings and raises abdomen). Finally, calculate the reaction rate. Response rate (%)=(response male number / test total number)×100; response male number refers to at least one of "exciteme...

Abstract

The present invention discloses a meadow moth gyplure and application thereof. The meadow moth gyplure according to the invention comprises trans-11-tetradecene acetic ester, trans-11-tetradecene aldehyde and n-tetradecanol. The mass ratio of trans-11-tetradecene acetic ester, trans-11-tetradecene aldehyde and n-tetradecanol is (1-7): (1-5): (1-15). The meadow moth gyplure can be applied for luring meadow gyplure and measuring the meadow gyplure pest situation. The gyplure of the invention has the following advantages: artificial synthesizing, simple structure, convenient synthesizing, easy generalizing, extraordinary using dosage, no environment pollution, high specificity, no fastness generation, no energy consumption requirement, and simple, safe and effective use. Compared with the artificial measuring, the method for luring meadow moth according to the invention can reduce the labor intensity and increase the standard property for counting the number of meadow moth. The meadow moth gyplure of the invention has great economic benefit and social benefit.

Description

technical field [0001] The invention relates to the synthesis and application of a meadow moth sex attractant. Background technique [0002] Meadow moth (Coxostege sticticalis L.) is a migratory pest of crops and pastures in my country. It breaks out intermittently and is mainly distributed in Northeast, North and Northwest regions. In a major occurrence year, a large area of ​​crops and pastures can be destroyed in a short period of time, causing serious disasters. In recent years, meadow borer adults have had a large outbreak in northern my country, and the degree of outbreak and the area of ​​occurrence are rare in recent years. The prevention and control of meadow moth mostly starts with prediction and forecast, and is controlled by chemical agents. Because the economic value per unit area of ​​grassland is low, the use of chemical pesticides in large quantities often outweighs the gains. Secondly, the extensive use of chemical pesticides will cause the deterioration ...
