| 摘 要： | 对烟粉虱Bemisia tabaci(Gennadius)在温室内甘薯寄主上主要生物学特性的研究表明：烟粉氮成虫喜光、喜湿，晴朗高温时活动性强，但扩散飞行能力弱；多在白天交尾，多在中午产卵，具有强的惫鬃性．若虫一生脱皮3次，若虫(除一龄初期)固定生活。卵的孵化及成虫的羽化也多发生在中午。雌雄性比为1．628：1，成虫平均寿命14．25天，雌成虫平均寿命比雄成虫长6．9天，每雌平均产卵158．5粒。以两性生殖为主，也可孤雌生殖，两性生殖的产卵量及卵孵化率均高于孤雌生殖。

| Abstract: | The main biological characteristics of sweetpotato whitefly,Bemisia tabaci (Gennadius), were observed on the sweetpotato host in greenhouse.The results showed that the adult of Bemisia tabaci liked light and humidity,with the intense activity in fine and hot day,and with the weak flying ability.The coition mainly occurred in daytime.It liked to live and oviposit on the tender leaf.The peak of egg laid and egg hatching, and of pupa emergence were at noon.The nymph exuviated three times.Except the early 1st instar,the nymph had the fixed characteristic.The ratio of female to male is 1.628:1. The average longevity of the adults lasted 14.25 days,and the longevity of adult female was 6.9 days more than adult male.The sweetpotato whitefly mainly developed with amphigony,and also with parthenogenesis. |
