中文摘要:
      研究棉花粉蚧雄成虫对不同虫态、不同日龄雌虫的性选择以及雌雄成虫日交配节律,为该虫性信息素的研究提供科学依据。采用四臂嗅觉仪测定了雄虫对不同虫态以及不同日龄雌虫( 3 龄若虫、1 日龄至8 日龄处女雌成虫、已交配雌成虫) 的选择性,观察了雄虫与雌成虫日交配节律。结果表明,雄成虫对4 日龄处女雌成虫的选择率显著高于其他虫态和日龄,一天内扶桑绵粉蚧交配高峰期出现在7∶00 - 9∶00。因此,推测4 日龄处女雌成虫和上午7∶00 - 9∶00 可能是释放性外激素的旺盛虫期和时间。
英文摘要:
      In order to provide scientific basis for the identification of sex pheromone of cotton mealybug Phenacoccus solenopsis,the sexual selection of male adults to different stages of female mealybugs and their copulation rhythm were tested in this paper. The selection of male adults to 3rd - instar nymphs,1 to 8-day-old virgin female adults and mated female adults were measured by four-arm olfactometer,and daily rhythm of mating activity for the female and male adults was monitored. The results indicated that males were attracted by 4-day-old virgin female adults significantly. The mating of P. solenopsis appeared a peak at 7∶00 - 9∶00 am. It was suggested that 4-day-old virgin female adults may release significant amount of sex pheromone at 7∶00 - 9∶00 am.
