Abstract

Oviposition, egg hatching and survival of newly-hatched larvae of Boophilus annulatus were studied in relation to infection by Babesia species and different temperature regimens. Infection of female ticks by Babesia bigemina or B. bovis had no effect on the time elapsed between engorgement and oviposition. The duration of oviposition was shorter in infected females incubated at 25 degrees C or 35 degrees C and infected females laid fewer eggs than the controls. No larvae hatched at 16 degrees C. B. bigemina-infected eggs hatched more quickly than uninfected eggs at 35 degrees C. The hatching percentage of B. bigemina-infected eggs was reduced by 50% at an incubation temperature of 25 degrees C and by 75% at 35 degrees C. At 16 degrees C there was no difference in the duration of survival of infected and non-infected larvae but at 25 degrees C and 35 degrees C the mean survival period of infected larvae was significantly lower than those of controls.

摘要

研究了微小牛蜱的产卵、卵孵化以及新孵化幼虫的存活与巴贝斯虫属感染和不同温度方案之间的关系。双芽巴贝斯虫或牛巴贝斯虫感染雌性蜱对饱血至产卵之间的时间没有影响。在25摄氏度或35摄氏度下孵化的受感染雌性蜱产卵持续时间较短，且受感染雌性蜱产的卵比对照组少。在16摄氏度时没有幼虫孵化。在35摄氏度下，双芽巴贝斯虫感染的卵比未感染的卵孵化得更快。在25摄氏度的孵化温度下，双芽巴贝斯虫感染的卵孵化率降低了50%，在35摄氏度下降低了75%。在16摄氏度时，感染和未感染幼虫的存活时间没有差异，但在25摄氏度和35摄氏度时，感染幼虫的平均存活期明显低于对照组。
