- forest sites than in forest fragments, whereas there were no significant differences between fragments of different sizes. These results provide further evidence for the effects of habitat size on the phorid-Acromyrmex system in a tropical rain forest, based on the abundance of parasitoids both as adults in the field and as reared immature phorids in the laboratory. Phorid parasitized leafcutter ants were most abundant in areas of continuous forest, and less abundant in the forest fragments. O Phorid flies are important parasitoids of leafcutter ants nd leafcutter ants can be found in Brazil's Southeastern Both phorid flies Atlantic Forest. The study provides evidence that this parasitoid-host interaction between phorid flies and leafcutter ant differs between continuous forest and forest fragments. Phorid flies were just as abundant in forest fragments as they were in continuous forest, but were less successful in parasitizing leafcutter ants.arrow_forwardMalaria is a disease in humans caused by infection with a protist, a eukaryotic organism.
