The southern cattle tick, Rhipicephalus (Boophilus) microplus, stands out as the most relevant ectoparasite in Brazilian cattle industry, causing annual prejudices that reach nearly 4 billion dollars. Constant worries with its control demand a vast knowledge of this parasite's biologic cycle, aiming to perform treatments in seasons that are not favorable to the ticks, maximizing efficacy. Most information about R. (B.) microplus were originated in other countries, and researches conducted in Brazil were, mostly, concluded a long time ago. Taking into consideration the severe climatic changes observed in the recent years, and the absence of studies regarding ecology and biology of such parasite in this region, the present study seeks to obtain such data through the observation, during two consecutive years, of all factors involved in the parasitic and non-parasitic life stages of the southern cattle tick. Besides, this study will evaluate the profile and behavior of this particular tick strain regarding its resistance against the main acaricides available and used by Brazilian cattle breeders. (AU)
