Embodiment Construction

[0021] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0022] 1. Extraction of sex pheromones

[0023] Collect aged or mature larvae, rear them in the laboratory, and prepare them after eclosion; use sexually mature unmated female moths, aged 3-5 days after eclosion. Extraction time is 6-7 hours after dark at night. Take adult moths, after ether anesthesia, gently press the abdomen with medical surgical tweezers, then cut off the 3 segments at the end of the abdomen, and transfer them into a clean glass vial with about 100ul. After leaching for 10 minutes, draw the solution part into the pointed bottom glass tube , concentrated under a slight nitrogen atmosphere, and analyzed by gas phase-mass spectrometry.

[0024] 2. Identification and synthesis

[0025] Gas phase analysis conditions: All synthetic sex pheromone compounds were analyzed on Agilent 6890GC-5975MS, the chromatographic column was ...

Abstract

The invention provides a sex pheromone composition of trichophysetis cretacea and a lure thereof and the sex pheromone composition is characterized in that: the composition of the sex pheromone of trichophysetis cretacea comprises a sex pheromone including a mixture of Z-11-hexadecene acetate, Z-11-hexadecenal and Z-11-hexadecenol in a mass proportion of 20-1000 mu g: 20-1000 mu g: 10-1000 mu g. The invention also discloses the correlative lure and the optimum trapping is realized when the total dose is 400 mu g. The invention discoveries and identifies the sex pheromone of trichophysetis cretacea for the first time and obtains an optimum composition ratio. The sex pheromone composition in the invention can trap and kill a plurality of male moths of trichophysetis cretacea (hendecasis duplifascialis), can be used for monitoring and controlling the population of jasmine trichophysetis cretacea and has an important effect and meaning for trapping and killing and forecasting of the trichophysetis cretacea.

Description

technical field [0001] The invention relates to a sex pheromone of C. bistriatus and related lures. Background technique [0002] The jasmine industry is the pillar industry of the jasmine producing areas in my country. But the pests of jasmine, especially the jasmine borer, which is commonly known as the jasmine borer, are particularly serious, and are the largest pest of jasmine, accounting for about 70% of the pest loss rate. In Qianwei County, there are larval hazards from April to December, especially from July to October. The jasmine bud borer is specific to the target. It mainly damages young shoots, flower buds and flowers with larvae. The damage rate of flower buds is over 90%. In the later stage, purple flowers and empty flower buds are caused, which greatly reduces the quality of jasmine flowers and affects their economic value, which ultimately affects farmers. income. Due to the harm of borers, it is very difficult to prevent and control. Farmers generally us...
