Problems solved by technology

[0006] At present, the synthesis cost of general pheromones is relatively high
The development of lower-cost plant-derived synergists is one of the ways to solve this problem, but how to optimize the mixture and achieve the maximum synergistic effect is a difficult problem

Embodiment Construction

[0021] The present invention will be specifically introduced below in conjunction with specific embodiments.

[0022] 1. Reagents

[0023] 1. Standard compound of cis-11-hexadecenal, standard compound of cis-13-octadecenal, standard compound of cis-9-hexadecenal, standard compound of phenylacetaldehyde, the purity of which is above 98%.

[0024] 2. Redistill dichloromethane.

[0025] 2. Preparation of sexual attractants

[0026] 1. Prepare cis-11-hexadecenal, cis-13-octadecenal, cis-9-hexadecenal, and phenylacetaldehyde respectively into redistilled dichloromethane solutions with a certain concentration.

[0027] 2. Mix according to the mass ratio set.

[0028] In this embodiment, the four components of cis-11-hexadecenal, cis-13-octadecenal, cis-9-hexadecenal, and phenylacetaldehyde are in the optimum weight ratio m 顺11-十六碳烯醛 :m 顺13-十八碳烯醛 :m 顺9-十六碳烯醛 :m 苯乙醛 = 48:10:8:60 mix.

[0029] It has been verified that the weight ratios of the four components of cis-11-hexadece...

Abstract

The invention relates to a sex attractant for attracting chilo suppressalis. The sex attractant is characterized by comprising cis-11-hexaolefine aldehyde, cis-13-octaolefine aldehyde, cis-9-hexaolefine aldehyde and phenylacetaldehyde, wherein the weight ratio of the four above components is 48:(1 to 50):(1 to 50):(1 to 100), further comprising one or more antioxidants such as hindered phenol antioxidanst, phosphite ester antioxidants and sulfo-antioxidants, and further comprising a high molecular weight hindered amine anti-ultraviolet light stabilizer or a low molecular weight hindered amine anti-ultraviolet light stabilizer. The sex attractant has the beneficial effects that a great deal of field trials show that the trapping and killing effect of the chilo suppressalis sex attractant can be greatly improved due to addition of phenylacetaldehyde, the trapping amount is large, the attraction effect is stable, and the problems that the conventional chilo suppressalis sex pheromone prevention and treatment effect is poor and the cost is too high are solved; the sex attractant is simple and safe to use, is relatively low in cost, can be used for predicting, broadcasting, preventing and treating chilo suppressalis, and has relatively good social and ecological benefits.

Description

technical field [0001] The invention relates to a substance used for preventing and treating the stem borer, in particular to a sex attractant for attracting the stem borer and a lure core made of the sex attractant, and belongs to the technical field of preventing and treating the stem borer. Background technique [0002] Chilo suppressalis (Walker) is one of the most important pests of rice in my country. In recent years, due to changes in cultivation, variety replacement, and global warming, the living environment of Chilo suppressalis has been greatly improved, and its population has been increasing. The upward trend is increasing, and the damage is getting worse. The current method of controlling Chilo borer mainly relies on chemical pesticides, but it has aroused public concern about food safety and environmental pollution, and because the larvae will bore into rice shortly after hatching, biological control becomes difficult. [0003] In order to overcome a series of ...
