VECTOR-BORNE DISEASES, SURVEILLANCE, PREVENTION Efficacy of Commercial Mosquito Traps in Capturing Phlebotomine Sand Flies (Diptera: Psychodidae) in Egypt

Four types of commercial mosquito control traps, the Mosquito Magnet Pro (MMP), the Sentinel 360 (S360), the BG-Sentinel (BGS), and the Mega-Catch Ultra (MCU), were compared with a standardCenters forDiseaseControl andPrevention (CDC) light trap for efÞcacy in collecting phlebotomine sand ßies (Diptera: Psychodidae) in a small farming village in the Nile River Valley 10 km north of Aswan, Egypt. Each trap was baited with either carbon dioxide (CO2) from combustion of butane gas (MMP), dry ice (CDC and BGS traps), light (MCU and S360), or dry ice and light (CDC).Trapswere rotated throughÞve sites in a 5 5Latin squaredesign, repeated four timesduring the height of the sand ßy season (June, August, and September 2007) at a site where 94% of sand ßies in past collections were Phlebotomus papatasi (Scopoli). A total of 6,440 sand ßies was collected, of which 6,037 (93.7%) were P. papatasi. Of the CO2-baited traps, the BGS trap collected twice as many P. papatasias theMMPandCDClight traps, andat least three timesmoreP. papatasi than the light-only MCU and S360 traps (P 0.05). Mean numbers ( SE) of P. papatasi captured per trap night were as follows: BGS 142.1 ( 45.8) MMP 56.8 ( 9.0) CDC 52.3 ( 6.1) MCU 38.2 ( 6.4) S360 12.6 ( 1.8).Results indicate that several typesof commercial traps are suitable substitutes for theCDC light trap in sand ßy surveillance programs.
