Effect of Diplocystis tipulae Sherlock (Eugregarinida: Apicomplexa), a coelomic gregarine pathogen of tipulids, on the larval size of Tipula paludosa Meigen (Tipulidae: Diptera).
This study demonstrates the debilitative effect of a coelomic gregarine, Diplocystis tipulae, on Tipula paludosa. The larvae were provided contaminated fresh grass leaves from a field where 40.0% of T. paludosa larvae were infected by this pathogen. Resultant infected larvae were separated into four groups according to infection level. Analysing their weights, lengths, and weight/length ratios showed that larval size decreased as infection level increased. Differences, especially at the lower and upper levels of the infection levels, were statistically significant. It was concluded that infection by D. tipulae affected the size of T. paludosa larvae resulting in smaller individuals.
