Problems solved by technology

For a long time, the method of preventing and controlling the moth moth, firstly, because the adults have phototaxis, black light lamps can be used to trap and kill adults during the high-incidence period. Although this method is effective, there are certain limitations in the application of black light lamps due to reasons such as power and economic conditions. Limitations; the second is to use chemical agents, but chemical pesticide control is easy to produce drug resistance, kill natural enemies, and at the same time, there will be problems such as pesticide residues and environmental pollution
The third is to use insect pheromone trapping method. Although this method is environmentally friendly, the amount of trapping pests is limited, and for various pests, multiple sets of trapping devices need to be set up, and the cost is relatively high.

Embodiment 1

[0016] The preparation of embodiment 1 cis-11-hexadecenyl-benzoate

[0017] The chemical structural formula of the compound cis-11-hexadecenyl-benzoate in the present invention is as follows figure 1 As shown, the synthetic route is as figure 2 shown.

[0018] Dissolve 1.0g (4.16mmol) of cis-11-hexadecenol in 25mL of N,N-dimethylformamide (DMF) solution, add 0.86g (6.24mmol) of K 2 CO 3 As an acid-binding agent, stir under ice-salt bath conditions, and when the temperature drops to about -20°C, slowly add DMF solution containing 0.88g (6.24mmol) benzoyl chloride dropwise, the system reacts for about 30min under this condition, remove After the ice-salt bath, the temperature was slowly raised to room temperature and the reaction was continued overnight. The reaction process was monitored by TLC. When it was detected that the reaction raw materials were no longer reduced, a small amount of deionized water was added to quench the reaction. The organic layer of the above reac...

Embodiment 2

[0019] Embodiment 2 field biological activity determination test

[0020] The plots with basically the same variety, sowing date, growth condition and daily management measures were selected as experimental fields. Will be located 0.2hm upwind 2 As the control area, three traps containing the sex pheromone lures of the moth moth were evenly placed in the center of the plot in an equilateral triangle as a blank control. The height of the traps was about 1m; the downwind outlet was 0.2hm 2 180-360 barrel-type traps containing the lure wicks of the moth moth are evenly placed per hectare, and 3 traps containing the sex information of the moth The traps of prime lures are used as monitoring; located in the middle 0.2hm 2 The area is used as a quarantine area, and no traps are placed.

[0021] Wherein, in the labyrinth area, each labyrinth formulation is set to 3 repetitions, and the labyrinth rate is averaged (analyzed with SPSS data processing software), and the specific dosag...

Abstract

The invention discloses a disorientation agent for Trachea atriplicis and application thereof. The disorientation agent for Trachea atriplicis is cis-11-hexadecenyl-benzoate, and the cis-11-hexadecenyl-benzoate is added into a PVC capillary to prepare a lure of the disorientation agent for Trachea atriplicis, and the lure has a better disorientation effect on Trachea atriplicis in the field. The mass of the cis-11-hexadecenyl-benzoate contained in the lure of the disorientation agent for the Trachea atriplicis is 0.8-1.8 mg. The disorientation agent control technology is environment-friendly, safe for natural enemies, high in specificity, easy in raw material obtaining and simple and convenient to operate, can play double roles of interference and disorientation, and has important significance on comprehensive treatment of Trachea atriplicis.

Description

technical field [0001] The invention relates to the technical field of preparation of insect sex pheromones, in particular to a pharophagia tropism agent and its application. Background technique [0002] Trachea atriplicis Linnaeus, also known as the white halberd copper-winged moth, belongs to Lepidoptera, Noctuidae, and is one of the important agricultural pests. It is polyphagous and feeds on the leaves of Polygonum, sorrel, brocade, Er Yuelan and other plants, endangering the whole process of plant growth and causing serious economic losses of crops. The moth moth is distributed all over the world, such as Europe, Japan, and Russia; in my country, it is mainly distributed in Beijing, Hebei, Henan, Shanghai, Jiangsu, Heilongjiang and other places. Adult insects can be seen under the lights in Beijing from June to September. For a long time, the method of preventing and controlling the moth moth, firstly, because the adults have phototaxis, black light lamps can be used...
