The activities ofAmblyomma testudinarium nymphs collected from the field in May, August, and October 2001 were observed in plastic cylinders placed outdoors. The activity of the field-collected nymphs in May was found from June to September, but disappeared from October to August 2002. The activity of the field-collected nymphs in August was found from September to November and in the spring (March to June) of 2002. However, the number of the active nymphs was small in the spring of 2002. The field-collected nymphs in October showed high activity in the spring (March to June) of 2002. Since the nymphs which molted in 2000 (old generation) did not survive until the spring of 2002, the field-collected nymphs in August and October 2001 appeared to include the new generation (molted in 2001). Thus, the participation of the new generation of A. testudinarium nymphs appears to occur from summer, although the number is small.
