Effect of night time-intervals, height of traps and lunar phases on sandfly collection in a highly endemic area for canine leishmaniasis

tThe activity of phlebotomine sand flies was monitored in a sub-urban area of Sicily in order to acquiredata on seasonality and to elucidate the effect of the night time-intervals, height of traps from ground andlunar phases on the abundance of the capture. The study was conducted in the farm of the University ofMessina (Italy). Light traps were placed as in the following: biweekly, from dusk to dawn, and from Mayto November; for three consecutive nights from 18:00 to 6:00, with the net bag being changed every 2 h;for 30 days, at different heights from 18:00 to 6:00. A total of five species (i.e., Phlebotomus perniciosus,Phlebotomus neglectus, Phlebotomus sergenti, Phlebotomus perfiliewi, and Sergentomyia minuta), three ofwhich are proven vectors of Leishmania infantum, were captured. The most abundant species was P.perniciosus (73.3%) followed by S. minuta (23.3%). The highest number of phlebotomine sand flies wascollected in August and September with a peak of collection recorded in the evening (i.e., from 20:01to 22.00). The number of phlebotomine sand flies collected at 50 cm above the ground was significantlyhigher (P = 0.041) than that captured at 150 cm. Results of this study shed light on the ecology of mainphlebotomine species in the Mediterranean area, and on the influence of some factors, such as time andheight of traps, on the light trap capture efficiency.
