The synergistic effect of light-emitting diodes (LEDs) and kairomones on the attraction of sand flies to light traps was evaluated. Octenol and lactic acid were used as chemical attractants. Green LEDs and the incandescent lamps were used as light attractants. Five CDC-type light traps with the respective combination of attractants (incandescent la...

In this paper, a non-powered trap equipped with light-emitting diodes (LEDs) designed for capturing small night-flying insects was field-evaluated for sampling anopheline mosquitoes. This new light trap, referred to as the Silva trap, was compared with the Centers for Disease Control and Prevention (CDC) miniature light trap in a livestock area in...
Article
To improve the efficiency of light traps in collecting phlebotomine sand flies, the potential effects of luminous intensity on the attraction of these insects to traps were evaluated. Sand flies were collected with Hooper Pugedo (HP) light traps fitted with 5-mm light-emitting diodes (LED) bulbs: green (520 nm wavelength—10,000, 15,000 and 20,000 m...
Article
In this study the phototactic response of anopheline mosquitoes to different luminous intensity light-emitting diodes (LEDs) was investigated. Centers for Disease Control-type light traps were changed by replacement of the incandescent lamps by 5 mm round type green (520 nm) and blue (470 nm) LEDs of different luminous intensities: green-LED traps...

... However, the artificial incandescent source has been replaced by light-emitting diodes (LEDs) in recent years. LEDs are devices which have been shown to attract and collect sand fly (Bishop et al., 2004;da Silva et al., 2019;Hoel et al., 2007;Lima-Neto et al., 2018;Silva et al., 2016Silva et al., , 2015, being as efficient as incandescent light, in addition to consuming less energy, and are more affordable in the market (Cohnstaedt et al., 2008). Studies evaluating LEDs for capturing sand fly in Brazil are restricted to the Northeast region, while there are no studies using LEDs as an alternative method for collecting sand fly in the Northern region, even considering that the region has a high diversity of species, as well as a vector of Leishmania species Resadore et al., 2017;Teles et al., 2016). ...
... The Sentinel Mosquito Arbovirus Capture Kit (SMACK), using a CO 2 attractant, identified Ross River virus and Barmah Forest virus in samples collected from North Queensland, Australia, and collected hundreds of mosquitoes (Johnson et al. 2015). A more recent design of a host-seeking passive trap is the Silva trap (Silva et al. 2019). This trap features an ultraviolet light source with a collection chamber; however, no suction fan, which, when tested, performed as well as a CDC-LT (Silva et al. 2019). ...
... Differences in vector density, species composition and sporozoite infection rates have been observed with CDC light traps in different settings, showing distinct geographical patterns but largely with a positive correlation in Anopheles vector density to indoor HLCs [10,18,23]. Differences in Anopheles vector density, species composition and sporozoite infection rates were observed in response to changes in CDC light source, trap position, collection time and presence or absence of a human bait [18,25,50,51]. Limitations notwithstanding, CDC light traps collected similar vector densities to indoor HLCs for highly anthropophilic vectors; An. gambiae s.s. and An. ...
