Abstract
The rates of infestation, successful parasitism, total encapsulation and mortality were measured after complete development of both D. melanogaster and D. simulans larvae parasitized by A. citri. Results showed that the parasitoids were almost never encapsulated in D. melanogaster larvae, while 45% were encapsulated in D. simulans. A. citri induced a targeted disruption of the hematopoietic organs and a decrease of the hemocytes load in host larvae of both species. Despite such disruptive immune effects most D. simulans larvae succeeded in encapsulating A. citri eggs, probably thanks to their ability to immediately mount a capsule after infestation. This work brings some insight into the diversity of the immune potentials evolved by Drosophila species towards parasitoids.
