Abstract

Gas chromatography (GC) analysis of 159 specimens (144 females and 15males) of Lutzomyia youngi collected in Shannon traps in a coffee plantation in the Andean region of western Venezuela, where leishmaniasisis endemic, revealed the presence of fructose, sucrose, glucose and maltose in the gut and crop of the wild sandflies. The identification of the sugars was confirmed by comparing retention times with those observed for standard sugars and those obtained from sandflies experimentally fed on known sugar solutions. Although the sandflies in nature may ingest each of the four sugars, the results suggest that it is more probable there is an invertase enzyme (glycosidase?) in the gut or crop of the sandfly which hydrolyses ingested disaccharides (e.g. sucrose) to the constituent monosaccharides (i.e. fructose and glucose). Ecological and altitudinal distributions of sandfly species may be relatedto the availability of specific sugar sources, with epidemiological implications. Identification of the preferred sugar could make breedingeasier and would facilitate further research on Leishmania-vector relationships.
