摘要: 受5龄末期和羽化初期较高保幼激素滴度的影响,褐飞虱Nilaparvata lugens(Stal)短翅型成虫性成熟比长翅型成虫早40~50h。5日龄前短翅型雌成虫的交配成功率较高,雄成虫的交配竞争能力较强;1、2日龄的长翅型雌成虫不交配,5日龄后长翅型成虫的交配能力渐渐超过短翅型成虫。实验种群的交配持续时间为(70.38±41.77)s;交配成功率为51.63%;雌、雄虫均可重复交配。一日中0~4h和10~14h交配成功率较高。

Abstract: Affected by a higher titer of juvenile hormone at the end of 5th nymphal instar and early stage after emmergence in vivo, the sexual maturation period of brachypterous adults of the brown planthopper was 40-50 hours earlier than that of macropterous adults. The percentage of successful mating of brachypterous females was higher and the mating ability of males was relatively stronger before 5-day age.Macropterous female adults did not mate at 1st. And 2nd. Day after emmergence. The mating ability of macropterous adults could surpass that of brachypterous adults gradually, the mating course of the experimental population lasted (70.38±41.77)s, and thepercentage of successful mating was 51.63%. Both males and females could mate repearly, and the percentage of successful mating was relatively higher during 0-4 o'clock and 10-14 o'clock in a day.
