Problems solved by technology

However, there are some limitations when using it, such as attracting non-target pests, sweet and sour liquid is volatile or will overflow when encountering rain, insects fall into the sweet and sour liquid container and rot due to soaking, which is not conducive to identification, etc.
[0005] However, the synergistic effect of these two compounds on the sex pheromone of pear borer moth alone or in combination has not been reported.

Embodiment 1

[0031] From May 30 to September 5, 2014, the synergistic effect test of synergists on sex pheromones was conducted in Doudian Liyuan, Fangshan District, Beijing.

[0032] First, the polyethylene centrifuge tube with a volume of 4mL was cleaned 3 times with 95% ethanol, and the ethanol was volatilized at room temperature, and a small hole with a diameter of 1mm was pricked on the bottle cap with a needle; the compound on the absorbent cotton strip (4cm×1cm) included The following 9 processes:

[0033] (1) 500 μL of α-terpinyl acetate is used alone,

[0034] (2) 500 μL of acetic acid is used alone,

[0035] (3) Mixture, 2000 μL of α-terpinyl acetate and 500 μL of acetic acid,

[0036] (4) Mixture, 1500 μL of α-terpinyl acetate and 500 μL of acetic acid,

[0037] (5) Mixture, 1000 μL of α-terpinyl acetate and 500 μL of acetic acid,

[0038] (6) Mixture, 500 μL of α-terpinyl acetate and 500 μL of acetic acid,

Abstract

The invention belongs to the field of agriculture, and provides a Grapholitha molesta (Busck) sex pheromone synergist, which comprises two compounds such as terpinyl acetate and acetic acid, wherein a volume ratio of the terpinyl acetate to the acetic acid is 1-4:1. The invention further provides preparation and applications of the Grapholitha molesta (Busck) sex pheromone synergist. Test results show that the mixture comprising 2000 [mu]L of the alpha-terpinyl acetate and 500 [mu]L of the acetic acid according to the ratio of 4:1 can be adopted as the synergist to increase the attractive capability of the sex pheromone on the male Grapholitha molesta (Busck), such that the moth trapping effect can be optimally enhanced.

Description

technical field [0001] The invention belongs to the field of agriculture, and in particular relates to a synergist for trapping or killing insects and its preparation. Background technique [0002] The small pear borer Grapholita molesta (Busck) belongs to the family Lepidoptera and is one of the worldwide pests of fruit trees. It is widely distributed in major fruit regions in temperate and subtropical regions. The range of hosts is wide, and the damage is hidden, especially peaches, nectarines, apples, pears, etc. are the most serious victims. The characteristics of host parasitism and hidden damage of larvae make it very difficult to control it with chemical pesticides, and it is easy to cause pesticide damage and pesticide residue pollution, which is contrary to green organic fruit production. [0003] Therefore, an effective control method or method is needed to control its occurrence and damage. Since the sex pheromone of the female pear borer was identified in 1965,...
