Parasitism, immune response, and egg production of the spearhead bluet (Coenagrion hastulatum) damselfly

Canadian Journal of Zoology, 2017
Theoretical models predict that parasites reduce reproductive success of their hosts, but very few empirical studies have given support to this. Using the spearhead bluet (Coenagrion hastulatum (Charpentier, 1825)) damselfly, we tested how immune response, wing length, and the number of both endo- and ecto-parasites affect egg production of host ...

Populations of the damselflyCoenagrion hastulatumat the edge of the species range have fewer gregarine and water mite parasites

Freshwater Biology, 2015
SummaryThe metapopulation theory predicts that the more distant a host population is from other populations, the more challenged will be a parasite to colonise it. We studied parasite prevalence of two parasite taxa across the geographical range of their host in Finland, from more dense host population structure in the south of Finland, towards the ...

The influence of cannibalism and prey density on growth in the damselfly Coenagrion hastulatum

Archiv für Hydrobiologie, 1996
The effects of prey density and cannibalism on individual growth rate in similar sized Coenagrion hastulatum (Zygoptera) larvae were studied in a 66 day laboratory experiment. The frequency of cannibalism decreased with increasing alternative prey densities.
