Density of sand flies (Diptera: psychodidae) in domestic and wild animal shelters in an area of visceral Leishmaniasis in the state of Rio Grande do Norte, Brazil.
Abstract: The objective of the present study was to determine the association of sand flies with the presence of domestic and wild animals in the peridomiciliary area. The sand flies were collected using direct aspiration and CDC light traps placed in animal shelters. The results suggest that different sand flies species have different behavioral characteristics in an apparent preference for animal baits and that Lutzomyia longipalpis and Lu. evandroi were the most eclectic species regarding their biotope choice. Lu. longipalpis showed a distinct preference for horses and Lu. evandroi for armadillos.

The study focused on understanding the behaviour of different sand fly species in relation to domestic and wild animals in Brazil, with particular emphasis on flies’ preferences for certain animal baits and biotopes.
Research Purpose and Methodology
- This research aimed to identify how sand flies, specifically Lutzomyia longipalpis and Lu. evandroi species, are associated with the presence of domestic and wild animals in a peridomiciliary (adjacent to the home) area in the state of Rio Grande do Norte, Brazil. The focus is significant due to the role that sand flies play in transmitting visceral Leishmaniasis, a parasitic disease.
- In order to collect the necessary data, the researchers used methods like direct aspiration and CDC light traps, tools which are commonly used in entomological studies for capturing insects.
- These tools were placed in various animal shelters to attract the sand flies.
Key Findings
- The researchers discovered that different species of sand flies exhibit varied behavioral characteristics, especially in their preference for animal baits and biotopes (natural habitats). This suggests that each species may have unique environmental preferences and interactions with host animals.
- Lutzomyia longipalpis and Lu. evandroi emerged as the most eclectic species relating to their biotope choices, implying these species potentially adapt quickly and thrive in diverse environmental conditions.
- More specifically, Lu. longipalpis displayed an apparent preference for horses, indicating that horses could be significant animal hosts for this species.
- On the other hand, Lu. evandroi displayed a notable preference for armadillos, suggesting that the survival and propagation of this fly species could be significantly linked with the presence of armadillos.
Implications of the Study
- The findings of the study can help in developing more effective pest management strategies, particularly in areas where visceral Leishmaniasis is prevalent.
- Understanding the behavioural preferences of these sand fly species and their relationship with specific animal hosts can provide insights on how to control their populations and potentially halt the spread of the disease.
