(Canestrini, 1887) in Morelos State , Mexico.  a[S.l.]: University of Floridac1980  a235p.  aTese Doutorado.  aThis research involved ecological studies  on the  cattle tick, Boophilus microplus (Canestrini, 1887), for the development of an  integrated pest management system as a pilot program for the Morelos State, Mexico, study area, taking into  account climate, types of cattle, and management. The  main studies were conducted by counting engorged female ticks in the  parasitic stage on native and introduced cattle. On native and Brahman cross cattle, 80% of the ticks were found infesting 40% of the  animals compared to European cattle on which 80% of the ticks were found on 70% of the animals. Seasonal tick populations were light in the middle of both wet and dry seasons and  were  related to paasturing procedures. The highest populations of the cattle tick were found  as the and of the west season. A survey to determine body region preference for this tick was made. Tick distribution on the host showed the highest tick populations on the reabelly area, than-inner-legs,  estucheon and tail base. Non-parasitic stage studies were conducted within tubes and cages placed into the soil to evaluate tick survival and egg laying. Maximum longevity observed for non-parasitic stages (adult femeale, eggs, and  larvae) was 190 days in Zacatepec, Morelos; 117 in Yecapixtla; and  96 days in Cuernavaco (Progreso). Meteorological stations near  the trials did not give precise enough information on ecological niches occupied by ticks to correlate the monthy mean temperature and the ticks life cycle. The duration of the tick life cycle was found to be regulated by the  microclimate which in turn was controlled by tick preference and novament in cages as ticks buried into the soil to lay eggs at optimum temperature...  aBoophilus Microplus  aCarrapato
