Resumen:
Th e mosquito Aedes aegypti is a vector of Dengue. Monitoring of mosquitoes in the fi eld isan important aspect of an effi cient disease-control strategy. Mosquito-monitoring methodsinclude egg-sampling using ‘ovitraps’ and adult-sampling using adult-traps. In recentyears, a novel adult-trap (BG-SentinelTM, Biogents AG, Regensburg) had been developedthat has since proven to be especially attractive for A. aegypti and related species, whencompared to other traps. Th e BG-Sentinel produces an upward air current and artifi cialhuman skin odors given off from a dispenser (BG-LureTM). Th is lure does not require CO2,a mosquito attractant, which is impractical or expensive for fi eld use. Th e aim of this workwas the evaluation of a new, improved and more cost-effi cient variant of the BG-Sentinel,named the MosquititoTM. To test the effi ciency of Mosquitito, two positive controls wereused: the BG-Sentinel and the MosquitaireTM, another and more rugged plastic versionof the trap. All three trap types used the BG-Lure. For testing, one trap of each type (3 intotal) was placed in an urban house garden in Diamante, Entre Rios, Argentina, and themosquitoes captured by each type was recorded. Experiments were carried out in parallelin two diff erent gardens, and the position of the traps was rotated aft er each samplingday. Ovitraps previously distributed all over the town had indicated a maximal density ofA. aegypti eggs near the gardens used. Preliminary data indicate that Mosquitito was themost effi cient trap. Th is device caught 63 % of a total of 960 mosquitoes trapped while theothers trapped less than 20 % each. However, only less than 3% of the total mosquitoestrapped were A. aegypti. Th e low A. aegypti capture rate could be due to diff erent reasons,including the timing of the sampling time window (i.e., the end of the mosquito season).
