| Abstract: |
| 【Objective】 Z/E-10-Hexadecenal,the sex pheromone of Dichocrocis puncticralis Guenee is to be synthesized by Wittig reaction.【Method】 The Wittig reaction used methylsulfinyl carbanion-dimethyl sulfoxide as strony base in the solution of DMSO at the temperatures 20-25 ℃.【Result】 1.2 g sex pheromone is synthesized.Its yields are 30%,and ratios of Z/E 20/80.The field experiments have showed that the sex pheromone has the best effect when its dose is 50 μg every bait.【Conclusion】 The sex pheromone synthesized by the method above can be used as attractants in field even without convert its ratios of Z/E. |
