A colony of Amblyomma parvum was started with engorged females collected from cattle in the Province of Salta (25 degrees 01' S, 63 degrees 56' W), Argentina. The progeny of those ticks were fed on rabbits and the non-parasitic stages maintained at 27 +/- 1 degrees C, 83-86% RH in darkness. The life cycle (prefeeding period not evaluated) had a mean duration of 99.6 days. The mean time (days) for the different phases of the cycle were as follows: feeding period of females, 8.0; pre-oviposition period, 5.7; oviposition period, 17.5; minimum incubation period of the eggs, 31.8; feeding period of larvae, 3.2; premoult period to nymphs, 10.9; feeding period of nymphs, 4.7; premoult period to adults, 17.8. The oviposition pattern was typical of an ixodid tick, including a linear relationship between weights of engorged females and the number of eggs laid (r = 0.8659). The males increased 18% in weight after feeding on hosts (P less than 0.01). The mean recovery rates of larvae, nymphs and females were 28.2%, 95.3% and 90.7%, respectively. The nymphs moulting to females were heavier (6.8 +/- 0.69 mg) than those moulting to males (3.2 +/- 0.29 mg) (P less than 0.01). A comparison of biological values of A. parvum with American and non-American Amblyomma species is presented.
用从阿根廷萨尔塔省（南纬25°01′，西经63°56′）牛身上采集的饱血雌蜱建立了微小扇头蜱种群。这些蜱的后代以兔子为食，非寄生阶段饲养在温度27±1℃、相对湿度83 - 86%的黑暗环境中。生命周期（未评估预进食期）平均持续时间为99.6天。该周期不同阶段的平均时间（天）如下：雌蜱进食期8.0；产卵前期5.7；产卵期17.5；卵的最短孵化期31.8；幼虫进食期3.2；若虫蜕皮前期10.9；若虫进食期4.7；成虫蜕皮前期17.8。产卵模式是硬蜱的典型模式，包括饱血雌蜱体重与产卵数之间的线性关系（r = 0.8659）。雄蜱吸食宿主血液后体重增加18%（P < 0.01）。幼虫、若虫和雌蜱的平均回收率分别为28.2%、95.3%和90.7%。蜕皮为雌蜱的若虫（6.8±0.69毫克）比蜕皮为雄蜱的若虫（3.2±0.29毫克）更重（P < 0.01）。还对微小扇头蜱与美洲和非美洲扇头蜱属物种的生物学特性进行了比较。
