The Synergism of Plant Volatile Compounds and Sex Pheromones of Mythimna separata
Volatile compounds from nectar plant were regarded as potential sex pheromone synergistic agent improving the sex pheromone activity of the Mythimna separata luring male moth.Each of the nine volatile compounds was mixed respectively with sex pheromone to verify its synergistic activity by indoor "Y" tube olfactometer behavior test and water pan trap trapping experiments in the field.The results indicated that increasing the plant source of compound within 4-20 mg dose difference was not significant effect on Mythimna separata lure,only 4 mg ethyl benzoate significantly increased the attractiveness of the pheromone to male moths.These results suggest that ethyl benzoate can be used as ideal sex pheromone lure core synergistic agent.
