Abstract: Characteristics of the biology and behavior of the phorid Neodohrniphora elongata Brown, 2001 in relation to workers of the host Atta sexdens rubropilosa Forel, 1908 were studied. Twenty-four field-collected females of N. elongata were released singly inside an observation chamber placed between a nest of A. sexdens rubropilosa and a foraging arena. Flies launched attacks on flies and failed four or five times before they would successfully attack ants and oviposit on the head of workers. Larvae of the parasitoid developed in the cephalic capsule of 63.8% of the 426 attacked workers; 218 flies emerged. N. elongata oviposited on bigger workers, or those with cephalic capsules 2.9 ± 0.4 mm wide. Capsule width seems to be important for the development of the parasitoid because failure in pupa formation and the non-emergence of adults occurred primarily among ants with capsules smaller than 2.9 mm. Flies that emerged in the laboratory had greater longevity when fed on honey solution at 10% than honey solution at 50%, or on distilled water only. The females emerged in laboratory had flight and attack behavior similar to those of field females, although second generation parasitoids could not be obtained. Additional studies on the impact of natural sources of carbohydrates and protein on the longevity and reproduction of N. elongate should be conducted to multiply this and other phorids of leaf-cutting ants in the laboratory.
