title: Development of the immature stages of Amblyomma lepidum (Acari: Ixodidae) under field conditions.
abstract: According to this study, the effect of seasonality on the development of larvae and nymphs of Amblyomma lepidum was highly significant (P< or =0.001). The moulting of larvae was only possible in the rainy season, where means of 76.8 and 73.1% were recorded in the first and the second year, respectively. Nymphs, in the same period, achieved 68.8 and 71.8% moult. In winter, only 11.8 and 12.2% of nymphs succeeded to moult in the first and the second year, respectively. Males outnumbered females, but the effect of seasonality on the male/female ratio was statistically insignificant. The development of both stages in summer was unsuccessful.
