摘要:

目的 在不同温湿度条件下饲养秃病蚤田鼠亚种,观察其生物学特性,为蚤类的防制提供资料。方法 在恒温恒湿条件下,采用成幼分养的方法饲养观察。结果 温度在(20.5±1)℃和(22.5±1)℃,相对湿度为(35±3)%时蚤的生长发育终止在1龄幼虫,而在(95±3)%条件下,(20.5±1)℃时生长发育终止在3龄幼虫期,(22.5±1)℃条件下可以完成从卵至成虫的发育,但存活率非常低,仅为8.75%。新羽化蚤饥饿状态下(22.5±1)℃的平均存活时间为11.68 d,短于(20.5±1)℃的15.07 d。该蚤较适温度为(22.5±1)℃,最适湿度为(75±3)%。结论 秃病蚤田鼠亚种的生长发育周期短、成蚤寿命长、繁殖力强。

Abstract:

Objective Nosopsyllus laeviceps ellobii (Wagner) were reared at different temperatures and relative humidities to determine the biological characteristics, providing basic evidence for the prevention and control of flea. Methods Adults and larvae were separately raised and observed under constant temperature and humidity. Results The growth of fleas ceased at the first larval stage under a relative humidity of (35±3)% and a temperature of (20.5±1)℃ or (22.5±1)℃, and the third stage under a relative humidity of (95±3)% and a temperature of (20.5±1)℃. At (22.5±1)℃, egg?to?adult development was achieved with nevertheless low survival rate. The mean survival time of new eclosed fleas was 11.68 days under starvation conditions, less than 15.07 d (22.5±1)℃, suggesting a sub?optimal temperature of (22.5±1)℃ and an optimum humidity of (75±3)%. Conclusion N. laeviceps ellobii is characterized by short metamorphic period, long adult life and strong reproductive capacity.
