Embodiment Construction

[0014] The present invention will be described in further detail below in conjunction with specific examples.

[0015] 1. Components of sex pheromones

[0016] The two standard compounds Z3Z6Z9-octadecatriene (Z3Z6Z9-18Hy) and Z3Z9-6,7-epoxy-octadecadiene (Z3Z9-6,7epo-18Hy) used in the test were synthesized by the laboratory, with a purity of Higher than 98%, the solvent for diluting the above compound adopts redistilled n-hexane.

[0017] 2. Lure core

[0018] A cylindrical rubber stopper with one end closed is selected as the sex pheromone carrier, green, with a diameter of 0.8 cm, a height of 1.2 cm, and a volume of 500 μl. The rubber stoppers were cleaned with n-hexane and dichloromethane, respectively, and dried naturally. The above treated rubber stopper is used as a release carrier for sex pheromone.

[0019] Prepare lures before the test. According to the test requirements, the components of the sex pheromone were prepared into a n-hexane solution with a set conce...

Abstract

The invention belongs to the technical field of Ectropis oblique prevention and cure, and in particular relates to a composition of Ectropis oblique sex pheromone, a lure of the composition and a use method of the lure. The composition of Ectropis oblique sex pheromone is composed of Z3Z6Z9-gadusene and Z3Z9-6,7-epoxy-octadecadienoic acid at the ratio of 6:(4-1):9; the above compositions are mixed to obtain a sex pheromone solution; the sex pheromone solution is added into a releasing carrier to obtain the lure; the obtained lure is fixed on an insect sticking plate to obtain a trapper; and the trapper is arranged in a tea garden and is positioned higher than the top end of a tea tent. The composition of Ectropis oblique sex pheromone and the lure of the composition have strong specifity on the male moth of the Ectropis oblique. According to the invention, the maximum occurrence period of insect pests can be effectively monitored to avoid blindly spray pesticide; in addition, the composition of Ectropis oblique sex pheromone and the lure have a better prevent and cure effect and can effectively protect and utilize the natural enemies of the insect pests.

Description

technical field [0001] The invention belongs to the technical field of tea geometrid prevention and control, and in particular relates to a tea geometrid sex pheromone composition, a lure and a method for using the lure. Background technique [0002] Tea geometrids belong to Lepidoptera, Geometridae, and Cladochoridae subfamily, and are important pests of tea trees in the southeast tea region of my country. Leaf-eating larvae are the main damage mode, and all leaves and buds of tea trees can be eaten up in outbreaks. At present, the main method of controlling tea inchworm is still using organic pesticides. However, the large-scale use of organic pesticides over the years has brought about consequences such as the reduction of natural enemies, the enhancement of pest resistance, environmental pollution, and excessive pesticide residues in tea products. As far as China's tea industry is concerned, it is urgent to adopt biological control technology to reduce the use of pestic...
