| Abstract: | To research the attractive effect of Syllepte derogata Fabricius female sex pheromone to male worm and provide scientific foundation for biological control,an experiment was conducted in the field and laboratory.Results show that from 1 to 7 d old,the female imago attraction and their extracts to male gradually decreased with the increase of both the distance and female age.Females imago sex pheromone aged 1 to 7 days were significantly more attractive to males than extracts from females of the same age.After oviposition for 3 d,female imago became as attractive to males as those before mating.The sex pheromone release level peaked during 22∶00～23∶00. |
