Embodiment Construction

[0019] The present invention will be further elaborated below in conjunction with specific implementation cases.

[0020] 1. Composition of sex pheromones

[0021] The two standard compounds Z3Z9-6, 7-epoxy-octadecadiene (Z3Z9-6, 7epo-18Hy) and Z3Z6Z9-octadecatriene (Z3Z6Z9-18Hy) used in the test were synthesized by the laboratory, with a purity of Higher than 98%, distilled n-heptane is used as the solvent for diluting the above compound.

[0022] 2. Lure

[0023] A PE capillary with an inner diameter of 0.5 mm and a wall thickness of 0.5 mm was selected as the carrier of the sex pheromone.

[0024] Prepare lures before the test. According to the test requirements, the components of the sex pheromone were prepared into a solution according to the set mass ratio, filled the whole 100m capillary tube, sealed a port after filling, and then sealed with a sealing machine and cut into 3cm-long tubes containing 10ul dose. The small section of capillary with both ends sealed is t...

Abstract

The invention discloses an application of a pheromone composition to controlling ectropis grisescens, and belongs to the technical field of controlling of the ectropis grisescens.The pheromone composition is composed of Z3Z9-6,7epoxy-ethyl linoleate and Z3Z6Z9-gadusene.The application has the advantages that the ectropis-grisescens pheromone composition and a lure core of the ectropis-grisescens pheromone composition have the quite good trapping effect on ectropis-grisescens male moths.The pheromone composition is used for trapping main lepidoptera-pest ectropis grisescens of tea trees in tea garden fields, the peak period of the ectropis grisescens can be effectively monitored, blind spraying can be avoided, the good control effect can be achieved, and natural enemies of pests can be effectively protected and used.

Description

technical field [0001] The invention belongs to the technical field of preventing and treating the gray tea inchworm, and in particular relates to the application of a pheromone composition in preventing and controlling the gray tea inchworm. Background technique [0002] Gray tea inchworm Ectropis grisescens Warren, 1894 Lepidoptera Lepidoptera Geometridae Ennominae Ennominae ( Ectropis ), is one of the main pests of tea trees in my country, and is distributed in major tea areas such as Fujian, Guangdong, Sichuan, Hunan, Henan, Zhejiang, Jiangsu and Anhui in China, and there is no distribution report abroad (Warren, 1894; Zhang etal. , 2014; Jiang Nan et al., 2014). tea inchworm Ectropisobliqua (Prout, 1915) also belongs to Lepidoptera Lepidoptera Geometridae Ennominae Ennominae ( Ectropis ), currently only known to be distributed in the three tea-producing provinces of Zhejiang, Anhui and Jiangsu, and mainly distributed in Japan and the Korean Peninsula abroad.
