The present study aimed to evaluate biological parameters of Rhipicephalus microplus in the non-parasitic phase in both field and laboratory conditions. It also aimed to assess correlations between duration (in days) of these parameters and climatic variables (humidity, rainfall, and soil temperature) and to estimate the annual number of generations of R. microplus in a tropical region. The non-parasitic phase of R. microplus in field and laboratory conditions was evaluated throughout the course of two years. A pasture was infested with engorged female of R. microplus, and biological parameters, including female pre-oviposition, female oviposition, egg mass incubation, larval pre-hatching phase, larval maturation, and larval longevity, were evaluated concomitantly with the collection of data on climatic conditions. The same parameters were also evaluated in a climatized chamber in the laboratory. The total duration of the non-parasitic phase in the field was longer in the dry season (1st and 4th life-cycle repetitions) than in the rainy season (2nd, 3rd, and 5th repetitions). Tick biological parameters for the non-parasitic phase in the laboratory were similar to those obtained in the field during the rainy season. The evaluated biological parameters were influenced mainly by environmental and ground-level temperatures, which modified egg mass incubation, larval pre-hatching, and larval longevity periods and, consequently, the total duration of the non-parasitic phase of the tick. The annual number of generations for the tick was estimated at five per year, which is alarming because it represents an increase, and so new studies into strategic control are needed.

本研究旨在评估野外和实验室条件下非寄生虫性小头hip的生物学参数。它还旨在评估这些参数的持续时间（以天为单位）与气候变量（湿度，降雨量和土壤温度）之间的相关性，并估计热带地区细小R. microplus的年代数。在整个两年的过程中，评估了田间和实验室条件下的微小拟杆菌的非寄生虫阶段。牧场上满是红micro雌虫，并与气候条件数据一起评估了包括雌性产卵，雌性产卵，卵孵化，幼体孵化前阶段，幼体成熟和幼体寿命在内的生物学参数。在实验室的恒温箱中也评估了相同的参数。旱季（第1和第4个生命周期重复）中田间非寄生虫阶段的总持续时间比雨季（第2，第3和第5个重复）更长。实验室中非寄生虫阶段的ick虫生物学参数与雨季在田间获得的相似。评估的生物学参数主要受环境和地面温度的影响，从而改变了卵的质量孵化，幼体预孵化和幼体寿命，以及 因此，the的非寄生阶段的总持续时间。the的年代数估计为每年五世，这令人震惊，因为它代表着增长，因此需要对战略控制进行新的研究。
