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.

On the Cytology and Taxonomic Position of Nudispora biformis N. G., N. Sp. (Microspora, Thelohaniidae), a Microsporidian Parasite of the Dragon Fly Coenagrion hastulatum in Sweden

The Journal of Protozoology, 1990
ABSTRACTThe microsporidium Nudispora biformis n. g., n. sp., a parasite of a larva of the damsel fly Coenagrion hastulatum in Sweden, is described based on light microscopic and ultrastructural characteristics. Merogonial stages and sporonts are diplokaryotic. Sporogony comprises meiotic and mitotic divisions, and finally eight monokaryotic sporoblasts

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 ...
