Modelling Cooperia oncophora: Quantification of key parameters in the parasitic phase

• Systematic review of four key life history traits of Cooperia oncophora.
• Meta-analysis estimates pre-adult and adult mortality, hypobiosis rate and fecundity.
• Estimates support the parameterization of future transmission models.
• Pre-adult mortality and fecundity were significantly affected by infection dose.

Cooperia oncophora is one of the most common intestinal nematodes in cattle. It is also the dose-limiting species for the most frequently used anthelmintics, and consequently, the species usually involved in reports of anthelmintic resistance. However, little information is available on its population dynamics, hindering the parameterisation of transmission models to support understanding of the impact of anthelmintic resistance, climate change and alternative control strategies on nematode epidemiology. This systematic review and meta-analysis provides estimates for key life history traits of the parasitic phase of C. oncophora and investigates potential influences of acquired immunity on these traits.
