Abstract

THE NIGHTLY FEEDING PATTERN OF MOSQUITOES, ASSOCIATED TO VIRAL TRANSMISSION DYNAMICS IN DOMESTIC AND WILD ANIMALS IN NORTHERN MEXICO IS STILL UNKNOWN. THE AIM OF THIS STUDY WAS TO DETERMINE SUCH PATTERN USING LURED TRAPS WITH HORSE AND HUMANS IN AN AGRICULTURAL FARM LOCATED IN THE METROPOLITAN AREA OF MONTERREY, NUEVO LEON, MEXICO. IN THIS AREA EQUINES AND SEVERAL AVIAN SPECIES, POSITIVE TO WEST NILE VIRUS, HAVE BEEN DETECTED. MOSQUITO COLLECTION WAS DONE FOR TEN CONSECUTIVE DAYS SINCE 18:00 TO 6:00 H THE FOLLOWING DAY IN JUNE AND JULY 2002. A TOTAL OF 9 196 MOSQUITOES OF 13 SPECIES WERE COLLECTED. THE SIX MOST COMMON SPECIES WERE: CULEX CORONATOR, CX. QUINQUEFASCIATUS, AEDES VEXANS, CX. TARSALIS, OCHLEROTATUS SOLLICITANS AND OC. TAENIORHYNCHU THE FEEDING PATTERN OF THESE MOSQUITOES, COLLECTED ON HORSE AND HUMAN, WAS CHARACTERIZED BY A PEAK OF DAWN ACTIVITY AND ANOTHER ONE DURING MIDNIGHT. FINDINGS SUGGEST THAT THE MOST COMMON SPECIES, WHICH FEED DURING EVENING-NIGHT, MIGHT BE INVOLVED IN ARBOVIRUS TRANSMISSION AMONGST DOMESTIC AND WILD ANIMALS AND, EVENTUALLY, MAY PASS THE INFECTION TO HUMANS.
