Embodiment 1

[0019] The preparation of embodiment 1 hazelnut image sex pheromone

[0020] Add the dichloromethane solution containing the hazelnut pheromone dropwise on the lure, after the dichloromethane solution containing the hazelnut pheromone volatilizes, add n-hexane dropwise on the lure, and wait for the n-hexane to volatilize The lure core containing the hazelnut sex pheromone attractant is prepared, the lure core is placed in the trap, and then the trap is placed in the field where the hazelnut phenomenon occurs more seriously. In order to ensure the release effect, 100-2000 μg hazelnut image sex pheromone was placed in each bag of 2mL lures, the average distance between the traps was 20m, and the height of the traps was set at 0.8m, 1.2m, 1.5m, 1.8m, 2m. In order to further illustrate the feasibility of the present embodiment, 10 specific formulas are provided in table 1:

Abstract

The invention provides sex pheromone for prevention and treatment of curculio dieckmanni, and a preparation method and application, and belongs to the technical field of insect sex pheromones. The sexpheromone is prepared from one or more than one of the following components: terpineol, cis-2-isopropenyl-1-methylcyclobutaneethanol, 3,7-dimethyl-1,6-octadien-3-ol, and phenylacetaldehyde. An dichloromethane solution containing the curculio dieckmanni sex pheromone is dropwise added onto a lure, after the dichloromethane solution containing the curculio dieckmanni sex pheromone is volatilized, normal hexane is dropwise added to the lure, after the normal hexane is volatilized, the lure containing the curculio dieckmanni sex pheromone is obtainedprepared, the prepared lure is loaded into aluminum foil to be sealed, and is subjected to refrigerated preservation at the temperate of -20 DEG C. the The invention provides the application of the sex pheromone in the aspect of biological prevention and treatment of the curculio dieckmanni. An environment-friendly and safe biological prevention and control measure is provided for prevention and treatment of filbert seed pests, namely curculiodieckmanni, the curculio dieckmanni pest situation can be monitored, mass trapping and mating disruption are achieved, and the advantages of being environmentally friendly and pollution free are achieved.

Description

technical field [0001] The invention belongs to the technical field of insect sex pheromones, and in particular relates to a sex pheromone for preventing and treating hazelnut and its preparation method and use. Background technique [0002] Hazelnut elephant (Curculio dieckmanni) is the main pest that harms hazelnuts. It mainly feeds on young shoots and twigs with adults, making the young leaves in a pinhole shape. The young shoots are incomplete and the twigs are broken. Some or all of them are eaten, and the feces in the fruit form insect fruit, resulting in low seed setting rate, small fruit, low fruit edible rate and tree vigor decline or death. According to the survey, the average insect fruit rate is about 30%. When it is serious, it reaches 100%, which seriously affects the cultivation and management of hazelnut economic forest species in our province. However, in China, due to the extensive economic development model, grass-roots production units mainly use chemica...
