Problems solved by technology

At present, although the components of tea geometrid sex pheromones have been registered in the Pheronet pheromone database, in these previous studies, the synthetic artificial compounds Z3Z6Z9-octadecatriene and Z3Z9-6,7-epoxy-decatriene The trapping test of octadecadiene in the field is very low, and the control effect on tea geometrid is limited

Embodiment 1

[0027] Under the conditions of 101KPa, 20°C to 25°C, use n-dodecane to dissolve the sex pheromone of the tea inchworm to prepare a solution of the sex pheromone of the tea inchworm, the total mass, components, mass fractions and corresponding See Example 1 in Table 1 for the volume of n-dodecane, and then use a pipette gun to place the tea inchworm sex pheromone solution on a cuff-type rubber stopper to prepare a tea inchworm sex pheromone lure.

Embodiment 2

[0029] Under the conditions of 101KPa, 20°C to 25°C, use n-dodecane to dissolve the sex pheromone of the tea inchworm to prepare a solution of the sex pheromone of the tea inchworm, the total mass, components, mass fractions and corresponding See Example 2 in Table 1 for the volume of n-dodecane, and then use a pipette gun to place the tea inchworm sex pheromone solution on a cuff-type rubber stopper to prepare a tea inchworm sex pheromone lure.

Embodiment 3

[0031] Under the conditions of 101KPa, 20°C to 25°C, use n-dodecane to dissolve the sex pheromone of the tea inchworm to prepare a solution of the sex pheromone of the tea inchworm, the total mass, components, mass fractions and corresponding See Example 3 in Table 1 for the volume of n-dodecane, and then use a pipette gun to place the tea inchworm sex pheromone solution on a cuff-type rubber stopper to prepare a tea inchworm sex pheromone lure.

Abstract

The invention discloses Ectropis obliqua sex pheromone, comprising in percent by weight: 18-72% of Z3, Z6, Z9-octadecatriene; 15-60% of Z3,Z9-6,7-epoxy-octadecadiene; 0.01-3% of an antioxidant; 0.01-5% of a photostabilizer; 1-5% of leaf alcohol; 1-5% of n-heptanal; 1-5% of tea polyphenols. The invention also provides a preparation method and lure core of the Ectropis obliqua sex pheromone; the preparation method incudes: dissolving the Ectropis obliqua sex pheromone with n-dodecane to obtain a solution; the lure core is made by placing 10 MuL to 100 MuL of the Ectropis obliqua sex pheromone in a release unit. The Ectropis obliqua sex pheromone is synergic to the luring of Ectropis obliqua, enables mass male insects to be lured and killed and mating to be interfered, thereby comprehensively treating Ectropis obliqua, and is significant to the prevention and treatment and prediction of Ectropis obliqua.

Description

technical field [0001] The invention relates to a tea geometrid sex pheromone, a preparation method and a lure core. Background technique [0002] Tea geometrid (Ectropis obliqu Prout) belongs to Lepidoptera (Lepidoptera), geometriidae (Geometriidae) subfamily (Ennominae), also known as arch worm, measuring inchworm, hanging silkworm. Widely distributed in my country, it is an important pest of tea trees in the tea regions of Zhejiang, Jiangsu and Anhui. Tea geometrid eats leaves with its larvae. When it breaks out, it can eat up all the leaves and shoots of tea trees, making the branches and stems of tea gardens bare, like fire, resulting in a reduction of more than 60% of tea production, and the quality of finished tea is seriously affected. It can lead to premature aging of tea trees, poor cold resistance, and susceptibility to freezing damage in winter. [0003] In order to control this pest, chemical control is mainly used at present. Over the years, the extensive us...
