扶桑绵粉蚧交配行为及能力的研究

本文对扶桑绵粉蚧的交配行为及交配能力进行观察，以期明确其交配行为和交配能力。研究发现，发现扶桑绵粉蚧雌雄虫均能多次交配，雄虫交配能力大于雌虫。雄虫交配次数为3～10次不等，平均为6.9次，以交配6次所占的比率最大，为26.7%。雌虫的交配次数为1～4次不等，平均为2.3次，以交配2次所占的比率最大，为40.0%。扶桑绵粉蚧的交配持续时间差异较大，从1.8 min到76.5 min不等，平均每次交配时间为11.5 min，其中以在10 min以内最多，为68.8%。上述研究为了解扶桑绵粉蚧的交配行为和研究昆虫性信息素提供了科学的依据。

Study on mating behavior and ability of Phenacoccus solenopsis Tinsley

In order to clarify the outbreak mechanism and improve the monitoring technical level, we studied the mating behavior and mating ability of Phenacoccus solenopsis in room temperature. The results showed that, the males and females could carry on mutiple mating, the mating ability of males was greater than the females. The male mating times were 3-10 times, and the 6 times was the largest proportion, which was 26.7%; The female mating times were 1-4 times, and the 2 times was the largest proportion, which was 40.0%. There was a significant difference of mating duration of P. solenopsis, that were from 1.8 min to 76.5 min; The average time for each mating was 11.5 min, and less than 10 min were the most, which was account for 68.8%. These studies provided a scientific basis for understanding the mating behavior of P. solenopsis and studying insect sex pheromone.
