The invasive species Trichocorixa verticalis shows a weaker immune response to water mite parasites than native species

Biological invasions provide an opportunity for ecological and evolutionary exploration of immune function in host–parasite interactions. Studying parasite-induced immune response in native and invasive species can provide novel insights into mechanisms underlying invasion success. This study aimed to establish the influence of mite ectoparasites on the invasion of the alien water boatman Trichocorixa verticalis (Corixidae) originating from North America.

The life cycle of an alien boatman

Trichocorixa verticalis (Corixidae) is native to North America but is well established as an alien in the Western Mediterranean region, where it is invasive in permanent coastal wetlands with high salinities. The annual cycle and generation time of T. verticalis was investigated in the introduced range in south-west Spain, through a combination of field surveys and laboratory experiments.
