“…As P. perniciosus is the main vector of L. infantum in the Madrid region (Gálvez In a recently published research, we observed no significant differences in capture rates between CDC and Fc light traps employing yellow diode light sources (Gálvez et al 2022). Similar results were obtained comparing blue and green diode sources and incandescent lights in studies conducted in Brazil with modified light traps (da Silva et al 2022). As such, all differences seen in the present study may be attributed to light colors.…”

“…In three different studies conducted in Brazil, green LED light provided the higher capture rates (Silva et al 2015(Silva et al , 2016, and this was attributed to a larger effect area and a reduced detrimental effect of moonlight on green diode light sources than conventional CDC light traps (da Silva et al 2020). Blue has also been suggested as to capturing the same abundance and diversity of sand flies as green and incandescent light sources, whilst red and ultraviolet seem ineffective in capturing those insects (da Silva et al 2022). Another Brazilian study revealed in vitro the preference of Lu.…”

Whether phlebotomine sand flies show a preference for different light colors remains controversial. As light-capture methods are widely used to study sand flies, knowing the visual stimuli they respond to could help the design of novel control tools to prevent their attraction to hosts. We have detected a significant preference of male Sergentomyia minuta for green and red light sources. Accordingly, male S. minuta were 2.16 and 2.01 times more likely to be lured by Flebocollect model traps with green and red diode-lights, respectively, than the commercial CDC traps. Flebocollect traps are homemade light traps developed through citizen science. Dipterans are widely considered unable to distinguish the color red so this finding was unexpected. To our knowledge, this is the first description of a color preference in a species of the genus Sergentomyia. Our research also confirms the great potential of Flebocollect light traps for use in medical entomology studies.

“…Two populations were observed within P. geniculatus and one was described as a new species, Psychodopygus francoisleponti ( Zapata et al 2012 ). Although this species was recently recorded in Rondônia ( Silva et al 2022 ), our group identified some differences when analysing specimens classified as P. geniculatus ( Resadore et al 2018 , Pereira Júnior et al 2019b , Torchitte et al 2020 ). We, therefore, suggest that future taxonomic studies clarify whether these specimens are, indeed, correctly classified, since a study conducted in Ecuador resulted in the reclassification of specimens in the Guyanensis series ( Zapata et al 2012 ).…”

BackgroundSandflies are insects important for the transmission cycles of the leishmaniases. Despite being studied since the 1960s in the State of Rondônia (Brazil), several gaps exist regarding our working knowledge of these insects. This study aimed to construct an up-todate database of sandflies using complementary information from the speciesLink database and the scientific literature, as well as to elaborate integrated abundance maps. We identified 153,155 records of sandflies captured in Rondônia between 1965 after exclusion, 147,258 reports (speciesLink -3,408, Rondônia studies -143,850) associated with 15 genera and 140 species were mapped. The most abundant species observed were
