RESUMO:

Deforestation has altered the biodiversity of phlebotomine sandfly fauna and created

forest islands, directly impacting on a biology and biology of the leishmaniasis

vectors. Entomological surveillance, as a measure recommended by the WHO to

control Leishmania, requires a capture of sandflies in different areas. For this

purpose, as light traps of the type Center for Disease Control (CDC) are like more.

Adaptations have been developed aiming at greater attractiveness of phlebotomine

sand flies and, consequently, more insects captured in the traps. The perception of

different wavelengths of the spectrum visible by phlebotomine sand flies is not yet

completely elucidated, the results are scarce and they are different depending on the

species and between the sexes. The study was based on the investigation of

phlebotomine sand fly fauna of an environmental protection zone in the north of

Natal-RN and its surroundings, also observing a attractiveness of each species in

relation to the visible viewer emitted by three different lamps: blue LED, Red LED

and incandescent control. The catches of sandflies occurred in 12 months, in six

points distributed equally in two distinct areas and daily the traps were changed of

position. Identification of captured sand flies revealed seven species divided into five

genera. The Kruskal-Wallis H’ test rejected the null hypothesis, revealing a

significant influence between the light spectrum emitted by the trap lamp and the

abundance of captured insects. The test of the generalized linear model showed a

significant influence between the area-sex and the area-treatment groups with the

number of sandflies collected. It is concluded that the blue LED, when compared to

the red and incandescent LEDs, shows better efficiency in the entomological

surveillance of sand flies, however, it is clear that not only the color of the light of the

trap influences the capture, but also the area where it is inserted the collection point.
