RESUMO

This study was conducted at the Laboratory of Endocctoparasitose Department of Preventive Veterinary Medicine, Veterinary School of UFMG and Model Farm Veterinary School in Pedro Leopoldo, Minas Gerais. Four different experiments were performed in the first experiment, we studied the behavior of larvae, nymphs and adults of Amblvomma cajennense into six different species of hosts: doméstuco rabbit (Oryctolagus cuniculus), domestic chicken (Gallus gallus domesticus), laboratory mouse ( Rattus norvegicus), Italian quail (Coturnix coturnix), Peking duck (Anas platyrhynchus) and African pigeon (Streptopelia decorate). A greater number of larvae and nymphs were recovered from rabbit, pigeon and chicken. The cycle of this species Carapate was completed only in rabbit and even then it was obtained has a degree of host specificity, especially for the mature forms, 2) the second experiment, the reproductive efficiency index (CEI) to A. cajennense was above 50% for ticks above 451 mg and there was no statistically significant difference between these indices in females in the field or placed in an incubator at 27 ° C and 80% humidity ralativa. This study suggests that weight range of engorged for better conversion from the egg is 451 mg, 3) the literature has referred to a survival for larvae, nymphs and adults of A. cajennense, fasting in the environment, respectively, five months a year and two years. In this experiment we found significant differences between the periods of stance and maximum survival of fasting larvae in an environmental chamber (6-8 months) and field (5-14 months). The pre-posture were similar in both environments: 4) Finally, from the data of literature and proposal of Leite et al. (1997) was made for strategic control A. cajennense applying six acaricide during the predominance of larvae (in May and June) and its acaricide during the predominance of nymphs (August and September) co with 10 day interval between each spray. Were collected and counted the ticks of five horses in the treated group and five in the control group before each spraying. The results indicated a significant difference between the two groups, suggesting that this control strategy is efficient and can be used in properties where the infestation of A. cajennense a problem
