湖南南山牧场越南血蜱(Hemaphysalis vietnamensis)生物学和季节动态的研究

本文首次阐述了越南血蜱的生物学和季节动态。雌虫产卵前期为19～24d，产卵期为11～22d，产卵数为168～672粒。卵孵化期为40～52d。雌虫在兔体饱血期9～13d。幼虫在兔体饱血期1～3d，饱血幼虫蜕化期为18～28d。越南血蜱成虫寄生牛体的季节动态：每年两次高峰为10～12月和2～5月，6～8月消失。

Studies on the Biology and Seasonal Fleuctuations of Haemaphysalis vietnamensis in Nanshan Farm, Hunan Province

The preoviposition period of engorged female is 19~24 days, and the oviposition period is 11~22 days. An individual female produces 168~672 eggs, and the incubation period of the eggs is 40~52 days. Female engorged in 9~13 days and larvae in 1~3 days on donor rabbit. Moult period of en gorged larvae is 18~28 days. Observation of seasonal fluctuation showed that the adults of H. Vietnamen sis appeared in October, December and February, May, and disappeared in June to August. This is the first presention of the biology and seasonal fluetuation of this rare species.
