Morphological and isoenzymatic differentiation of Phlebotomus perniciosus and Phlebotomus longicuspis (Diptera: Psychodidae) in Southern Morocco.
Morphological and enzymatic characterization of Phlebotomus perniciosus and Phlebotomus longicuspis in Morocco is reported. Twenty-nine localities in central and southern of Morocco were sampled and compared with three localities from the Rif (northern Morocco). For morphological study, sand flies were collected by sticky-paper traps. For males, the morphology of the copulatory valves (aedeagi) was examined and the number of coxite hairs was recorded. For isoenzyme analyses, specimens were collected in CDC light traps and immediately conserved at -80 degrees C. P. perniciosus samples from the south of Morocco, up to 150 km from Marrakech, showed single-pointed aedeagi curved at their apices, indistinguishable from the atypical morph of P. perniciosus, previously described in northern Morocco. Twelve enzyme systems were tested and the qualitative analysis of zymogram profiles revealed eight polymorphic loci (glucosephosphate isomerase (GPI), phosphoglucomutase (PGM), hexokinase (HK), fumarate hydratase (FUM), malate dehydrogenase 1 (MDH1), malate dehydrogenase 2 (MDH2), 6 phosphogluconate dehydrogenase (6PGD) and aconitase (ACO)). Enzyme loci showed fixed alleles diagnostic for P. perniciosus (aconitase) and P. longicuspis (aconitase and hexokinase).
