Drop-off patterns for engorged adult females, nymphs and larvae of Rhipicephalus appendiculatus
Published online by Cambridge University Press: 19 September 2011
Abstract
A drop off rhythm of engorged Rhipicephalus appendiculatus Neumann was demonstrated for females and engorged nymphs, but not for larvae. Seventy per cent of 1279 engorged R. appendiculatus females dropped off the animals between 0800 and 1000 hr, while 66% of 2736 engorged nymphs dropped between 1600 and 1800 hr.
Females which were put on the animals at night (2000 hr), started to drop-off 24 hr later, than those put on in the day (0900 hr). Ticks which were fed on tick-sensitized animals also started to drop off 24 hr later, than those on tick-naive animals.
The implications of these results on tick control management are discussed.
Résumé
Rythme de détachement de femelles adultes, de nymphes et larves gorgées de Rhipicephalus appendiculatus. Un rythme de détachement de leurs hôtes de femelles et nymphes Rhipicephalus appendiculatus Neumann gorgées a été déjá décrit mais rien n'a été fait en ce qui concerne les larves. Soixante dix pourcent des 1279 femelles gorgées se détachent des animaux entre 0800 heures et 1000 heures tandis que 66% des 2376 nymphes gorgées tombent entre 1600 heurs et 1800 heures.
Les femelles présentées aux animaux la nuit (20 heures) commencent á se détacher 24 heures après celles qui ont été mises sur les animaux le jour (9 heures). Les tiques nourries sur des animaux déjá sensibilisés commencent á se détacher 24 heures aprés celles nourries sur des animaux n'ay ant jamais eu contact avec des tiques. Les implications que peuvent avoir ces résultats en matière de contrôle de tiques ont été discutées.
