Abstract

A quantitative index of resistance to ticks, which had been derived from results of artificial infestation of East African zebu cattle with a Rusinga Island (Lake Victoria) stock of Rhipicephalus appendiculatus, was tested for consistency using three additional tick stocks—from a laboratory (Muguga), Intona (Trans Mara) and Ukunda (Kenya coast). Results from all the stocks gave similar indices when compared with corresponding values for the Rusinga stock, confirming both the validity of the mathematical function and of the use of any local stock of the tick species for assessing the resistance of cattle to R. appendiculatus.

Résumé

Un index quantitative de la résistance aux tiques dérivant du résultat d'une infestation artificielle du zebu africain par le Rhipicephalus appendiculatus de l'ile de Rusinga (Lac Victoria) a été testé pour sa consistence lorsque 3 différentes espèces des tiques du laboratoire (Muguga), de Intona (Trans Mara) et Ukunda (Coast Kenyanne).

Le résultat étaient similaire pour toutes les espèces. Ceci confirme la validité de la fonction mathématique et l'utilization de m'importe quelle espèce des tique pour évaluer la resistance.
