Studies on ticks of veterinary importance in Nigeria. VIII. Differences observed in the biology of ticks which fed on different domestic animal hosts.
Abstract: Ticks of the species Amblyomma variegatum (Fabr.), Boophilus decoloratus (Koch), Boophilus geigyi Aeschl. et Morel, and Hyalomma rufipes Koch were detached from cattle, sheep and horses and the influence of these various hosts on the biology of ticks was investigated. No A. variegatum was found in horses. The parameters studied were preoviposition and oviposition periods, ovipositional capacity, eclosion period, hatching patterns, egg sizes and temperature effect. Although the preoviposition and eclosion periods were similar in each tick species irrespective of the host from which the adults were detached, the oviposition period was longest among ticks detached from cattle and least among those detached from horses. The ticks engorged on cattle also laid the highest number of eggs and those which engorged on horses laid the least number. The hatching pattern of the eggs in any tick species was not influenced by the host from which the female was detached. The lengths of eggs of the ticks whose adults were detached from horses were generally smaller than those detached from cattle and sheep. Temperature affected the adult females detached from cattle, sheep and horses equally and this was also true of the larvae they produced. The practical field applications of these results are discussed.

This research article investigates the biological differences in various species of ticks found on different domestic animal hosts in Nigeria. It examines factors such as feeding periods, egg-laying capabilities, hatching patterns, egg sizes, and the effects of temperature on these ticks.
Introduction and Study Design
- The study focuses on the ticks of four different species: Amblyomma variegatum, Boophilus decoloratus, Boophilus geigyi, and Hyalomma rufipes. All of these ticks were detached from a variety of domestic animals like cattle, sheep, and horses for comparison and study.
- The objective was to investigate the differing biological traits and how these hosts might influence the ticks’ biology, due to variations in the host’s body and ecology.
Parameters Studied
- The research focused on several key parameters including: the preoviposition (period before egg laying) and oviposition (egg-laying) periods, oviposition capacity (the number of eggs a tick can produce), eclosion period (time it takes for the egg to hatch), hatching patterns, egg sizes, and the effects of temperature.
Findings and Observations
- It was observed that Amblyomma variegatum was absent in horses. The preoviposition and eclosion periods were found to be consistent across all tick species regardless of their host.
- The oviposition period varied according to the host. Ticks detached from cattle had the longest oviposition period while those detached from horses had the shortest. Cattle-fed ticks also laid the highest number of eggs compared to the other hosts. Conversely, ticks feeding on horses laid the fewest eggs.
- The hatching pattern of the eggs didn’t seem to be influenced by the host animal. However, the size of the tick’s eggs was generally smaller in those detached from horses compared to those detached from cattle and sheep.
- Temperature was observed to impact all adult female ticks, no matter the host, as well as their resulting larvae, in the same way.
Practical Applications
- The research concludes with discussions around the practical applications of these findings, possibly towards developing more host-specific tick control or prevention strategies in livestock management or veterinary medicine.
