Abstract

The interactions of the hyperparasitoidsCatolaccus aeneoviridis (Girault) andSpilochalcis side (Walker) with the microsporidansNosema heliothidisLutz & Splendor andN. campoletidisBrooks & Cranford are described. Neither hyperparasitoid species was infected upon parasitization of pupae of the primary parasitoidCampoletis sonorensis infected withN. heliothidis. However, upon development inCampoletis pupae infected withN. campoletidis, adults ofC. aeneoviridis were infected systemically; trassovarian transmission of the microsporidan to F3 individuals was also shown.S. side was also infected byN. campoletidis but in this hyperparasitoid, microsporidan development was arrested in the sporoblast stage. Mature spores were not observed in infectedS. side adults and the microsporidan was not transmitted transovarially. The interactions of the hyperparasitoids with the two microsporidans were not demonstrably detrimental as data on the developmental period and adult longevity of infected or exposed hyperparasitoids were similar to those of control individuals.

Résumé

Les auteurs décrivent les interactions entre deux hyperparasitoides,Catolaccus aeneoviridis etSpilochalcis side, et les microsporidies,Nosema heliothidis etN. campoletidis. Aucune des espèces hyperparasitoides ne fut infectée quand elles ont parasité des nymphes du parasitoide primaire,Campoletis sonorensis infecté parN. hehothidis. Cependant, les adultes deC. aeneoviridis furent infectés systématiquement lors qu'ils se développèrent dans des nymphes deCampoletis infectées parN. campoletidis; la transmission transovarienne de la microsporidie jusqu'aux individus de la F3 a été également démontrée.S. side a été aussi infecté parN. campoletidis mais chez cet hyperparasitoide le développement de la microsporidie a été arrêté au stade de sporoblaste. Les spores mures n'ont pas été observées dans les adultes deS. side et la microsporidie n'est pas transmise par la voie transovarienne. Les interactions entre les hyperparasitoides et les deux microsporidies n'ont pas d'effet nuisible démontrable puisque la durée de développement et la longévité des adultes chez les hyperparasitoides contaminés ou exposés sont comparables à celles observées chez les témoins.
