Embodiment 1

[0036] Example 1: Synthesis of Candidate Compounds for Sex Pheromone in Walnut Moth Moth

[0037] The applicant's research group has been conducting research on the sex pheromones of the walnut moth since 2008. Through years of hard work, it has broken through the difficulties of difficult synthesis of related compounds and low yields. Through the optimization of the Wttig reaction and the catalyzed coupling reaction The application of (Coupling) synthesized and derivatized various 13, 14, and 16 carbenol compounds. Such as Z-9-16: OH, Z-9-16: OAc, Z-9-13: OH, Z-9-13: OAc, Z-8-13: OAc, Z-8-13: OH, E -9-16: OH, E-9-16: OAc, E-7-16: OH, E-7-16: OAc, E-5-16: OH, E-5-16: OAc and more than 40 kinds compound. It has laid a good foundation for the synthesis, identification of active compounds and acquisition of standard products for the study of sex pheromones of walnut moth.

[0038] For example, the stereoselective synthesis of E-7-hexadecen-1-ol (E-7-16: OH) and E-7-hexadecen-1...

Embodiment 2

[0060] Example 2: Exploration of field extraction conditions for sex pheromone of walnut moth

[0061] Through years of research, it has been found that the walnut moth does not secrete sex pheromones under the current indoor breeding conditions. There was no obvious sexual excitement in the walnut moth without walnut branches, but there was sexual excitement in the condition of walnut branches, but it was not as strong as that in the wild. It was also found that under indoor conditions, although there are sexually excited behaviors such as marriage flying and tail movement, the male and female individuals have no mating behavior.

[0062] The research shows that the walnut elevating moth can only secrete sex pheromone under field conditions. Through exploration, the conditions, extraction timing and method of raising and producing sex pheromone of walnut elevating moth have been established. The specific method is as follows:

[0063] From 2014 to 2015, in the demonstration...

Embodiment 3

[0067] Example 3: Identification of key components of sex pheromone of walnut moth moth

[0068] Carry out GC-MS analysis to the extract, the gas chromatogram (GC figure) of the crude extract from the abdomen end of the walnut moth female moth in the excited stage is shown in figure 2 . In order to exclude the impurity peaks from other tissues in the insect body during the pheromone extraction process. Theoretically, the n-hexane extracts from the abdominal end of male adults that would not contain pheromone and the abdominal end of female adults in the non-excited stage were used as controls. containing pheromone) and the n-hexane extract from the abdomen terminal of male and non-excited female adults were analyzed by gas chromatography. Control 1: The gas chromatogram (GC chart) of the crude extract from the abdomen terminal of the male moth walnut elevating limb moth is shown in image 3 . Control 2: The GC chart of the crude extract from the abdomen terminal of the fe...

Abstract

The invention discloses an atrijuglans hetaohei Yang sex pheromone component as well as extraction, identification and synthesis methods thereof. The atrijuglans hetaohei Yang sex pheromone component is synthetized through the following steps of: extracting female sexual glands during a sexual excitation period of atrijuglans hetaohei Yang through a field rearing condition; extracting sex pheromone substances form the female sexual glands, and identifying active ingredients of the sex pheromone substance; and then performing a catalytic coupling reaction. The atrijuglans hetaohei Yang sex pheromone component is anti-5-hexadecene acetate. The sex pheromone component is dissolved in an organic solvent to prepare an induced cell which is used for monitoring, predicating and forecasting the emergence period of the atrijuglans hetaohei Yang, so that scientific reference is provided for effectively preventing and treating atrijuglans hetaohei Yang in proper time.

Description

technical field [0001] The invention belongs to the technical field of insect sex pheromones, and specifically relates to a walnut moth sex pheromone component and the extraction, identification and synthesis of the walnut moth sex pheromone component. Background technique [0002] Walnut is a traditional economic tree in my country's hilly and mountainous areas. In January 2015, the General Office of the State Council issued the "Opinions on Accelerating the Development of Woody Oil Industry", which proposed to speed up the development of woody oil industry and effectively maintain national grain and oil security. As an important woody oil plant, walnut has been growing rapidly in recent years. Atrijuglanshetaohei Yang is a fruit-boring pest that specifically harms walnuts. It is distributed in Beijing, Henan, Hebei, Shaanxi, Shanxi, Gansu, Sichuan, Guizhou, Shandong, Hubei and other places. It eats walnut green skin and even fruit with larvae. Kernel, the victim fruit gra...
