Abstract
The major parasitoid attackingOscinella spp. larvaeChasmodon apterus, demonstrates an ability to avoid superparasitism. However, avoidance is imperfect and in the present work 13% of parasitized larvae were superparasitized. When superparasitism occurred the parasitoid larvae competed, apparently by physiological methods, although physical fighting was observed on one occasion. Multiple parasitism was rare.
Résumé
Chasmodon apterus Nees (Braconidae) est généralement le principal parasitoide des larves d'Oscinella spp. et deGeomyza tripunctata sur le ray-grass.C. apterus a la capacité d'éviter le superparasitisme, mais seulement de façon partielle; ainsi dans la présente étude, 13% des mineuses parasitées étaient superparasitées. Lorsqu'il y avait superparasitisme, la compétition entre les larves de parasitoides était apparememment d'ordre physiologique. Cependant, un cas de lutte physique a été observé. Le parasitisme multiple était rare.
