Summary

Characteristics of the life cycle of female ticks (Amblyomma variegatum, Hyalomma truncatum andBoophilus geigyi) fed on N'Dama and zebu cattle were studied in the laboratory from pre-oviposition period to larval development. Percentage ofA. variegatum eggs hatched and engorgement weight ofH. truncatum were lower in ticks collected on N'Dama than on zebu cattle. Laboratory results confirmed field observations of species specific tick resistance in the N'Dama breed.

Comparaison Des Caracteristiques Du Cycle Vital Des Tiques Femelles Recoltees Sur Du Betail Ndama Et Zebu

Résumé

Les auteurs ont étudié en laboratoire les caractéristiques du cycle vital des tiques femelles (Amblyomma variegatum, Hyalomma truncatum etBoophilus geigyi) nourries de la période d'oviposition jusqu'au stade du développement larvaire, sur du bétail de race Ndama et Zebu. Le pourcentage d'oeufs éclos d'Amblyomma variegatum et le poids des femelles gorgées deHyalomma truncatum étaient plus faibles chez les tiques récoltées sur le bétail Ndama que sur les Zebus. Les résultats au laboratoire ont confirmé les observations de terrain sur le caractère lié à l'espèce de la résistance spécifique aux tiques de la race Ndama.

Comparacion De Las Caracteristical Del Ciclo De Vida De Las Garrapatas Hembras Recolectadas En Ganado N'Dama Y Cebu

Resumen

Se estudiaron en el laboratoria las características del ciclo de vida de garrapatas hembras (Amblyomma variegatum, Hyalomma truncatum yBoophilus geigyi), alimentadas en ganado N'dama y cebú desde el período de oviposición hasta el desarrollo de la larva. El porcentaje de los huevos deA. variegatum eclosionados y el peso de las garrapatas adultas ingurgitadas de H. truncatum fueron inferiores en las garrapatas recolectadas en ganado N'dama que en cebú. Los resultados de laboratorio confirmaron las observaciones de campo sobre la existencia de una resistencia a las garrapatas especifica de especie en el ganado N'dama.
