Summary

A series of experiments, designed to improve the feeding methods used for the tickRhipicephalus appendiculatus in East Coast fever research, were carried out in the laboratory using rabbits and cattle as tick hosts. When nymphal ticks were fed on cattle in varying numbers, large numbers of ticks took longer to engorge and mean engorged weight of tick batches was lower, than for ticks fed in smaller numbers. Two thousand nymphs per ear fed satisfactorily, and this number is now used as a standard.

Quelques observations sur le comportement alimentaire de la tique Rhipicephalus appendiculatus (Neumann, 1901) sur le bétail et le lapin au laboratoire

Résumé

Une série d'expériences, destinées à améliorer les méthodes d'alimentation de la tiqueRhipicephalus appendiculatus, dans les recherches effectuées sur l'East Coast Fever, ont été entreprises en laboratoire, en utilisant des lapins et des bovins comme hôtes.

Lorsque les nymphes sont nourries sur le bétail en grand nombre, elles sont plus longues à se gorger, et le poids moyen des tiques gorgées est plus faible que lorsque les nymphes sont moins nombreuses. Deux mille nymphes par oreille se nourrissent de façon satisfaisante et ce nombre est maintenant utilisé systématiquement.

Algunas observaciones sobre la conducta alimenticia de la garrapata Rhipicephalus appendiculatus (Neumann, 1901) en bovinos y conejos en el laboratorio

Sumario

Se han llevado a cabo una serie de experimentos en el laboratorio usando conejos y bovinos como hospederos de garrapatas, los cuales fueron concebidos con la idea de mejorar los metodos de alimentacion usados en el caso de la garrapataRhipicephalus appendiculatus en la investigación de ‘a Fiebre del Este. Cuando un gran número variado de ninfas se alimentó en bovinos, una gran cantidad de garrapatas tomaron mas tiempo en alcanzar gravidez y el peso promedio de gravidez de lotes de garrapatas fue menor que el de las garrapatas alimentadas en pequeñas cantidades. Se alimentaron dos mil ninfas por oreja satisfactoriamente y este número es ahora considerado como standard.
