福州地区的微小牛蜱Boophilus microplus在牛体表终年均有寄生,以7、8、9、3个月为寄生高峰期。经人工饲养观察,每年发生4代。第一代需要63—88天,第二代42—56天,第三代44—62天,第四代90—152天。以第四代未吸血幼蜱或第三代未吸血幼蜱越冬。未吸血幼蜱最长能存活227天。雌蜱一生共产卵1589～4138粒(平均2986.3粒),产完卵后约0～14天死亡。饱血雄蜱一般存活不超过1个月。饱血雌蜱的体重与产卵量和产卵期呈相关[Y(产卵量)=00.945,P<0.01;r(产卵期)=0.490,p<0.05]。
Boophilus microplus, a bovine tick in Fuzhou, all had parasitism all year round in cattle body surface, and peaked at 7, 8, 9 and 3 months. Observed by artificial feeding, 4 generations occur each year. The first generation takes 63-88 days, the second generation 42-56 days, the third generation 44-62 days, the fourth generation 90-152 days. To the fourth generation of non-aspergillosis or third-generation non-asphyxiated tick overwintering. Larvae did not vomit up to 227 days. Female ticks co-spawning a total of 1589 ~ 4138 tablets (average 2986.3 tablets), the production of eggs about 0 to 14 days after the death. Blood and male ticks generally survive less than 1 month. The body weight of full females was correlated with egg production and spawning period [Y (fecundity) = 00.945, P <0.01; r (spawning period) = 0.490, p <0.05].
