Abstract
The distribution in Trinidad of the tick Amblyomma cajennense is defined, and the methods used to determine the boundaries of the infested areas are outlined. The relationships between climate, vegetation and husbandry methods and the distribution of the tick are described. Monthly tick collections from specific animals to determine exact seasonal variations were not possible but a study was made of the normal life cycle under laboratory conditions, the results being used to assist in interpreting the field picture and formulating methods of control. Possible systems of control are outlined and mention is made of the feasibility of eradication of the species in Trinidad.
