摘要
中华按蚊 Anopheles sinensis以成蚊越冬。在上海、无锡从11月至3月上旬当气温超过10℃时,于畜棚可诱捕到新饱血蚊。卵巢发育观察表明,71.5％为发育蚊,吸血蚊生殖营养协调。另外还捕到个别经产蚊(1.3％)。采自户外草堆等处的越冬蚊人工喂血与卵巢发育观察表明,64％为滞育蚊,35％为静止的发育蚊。滞育蚊出现于11月份,持续2个月,到2月底及3月上旬滞育开始解除。本研究结果表明,中华按蚊在上海、无锡是以深滞育(3％)、浅滞育(41％)与静止(56％)的生理状态越冬。
It is well known that Anopheles sinensis Wied. overwinters in adult stage. In Shanghai and Wuxi, freshly engored females can be found in livestock sheds when the temperature is above 10℃. from November to early March. Observations on the ovarian development of the females showed that 71.5% of them are in nondiapause state. Fed females present gono-trophic concordances. In addition, a few parous females (1.3%) were collected from the livestock sheds. Observations on the feeding activity and ovarian development of hibernating females collected from fresh rice straw piles and grass showed that 64% of them has entered diapause and 35% failed to diapause (quiescence). The diapause females appeared from November and the state lasted about two months. From the end of February and early March the ovarian diapause began to terminate. The results show that Anopheles sinensis overwinters at least in physiological states of diapause (3%), light diapause (41%), and quiescence (56%) in Shanghai and Wuxi.
