“…The main family in the Gammaproteobacteria order is Enterobacteriaceae, which is present in both Phlebotomus and Lutzomyia (Fraihi et al, 2017). The microbiota composition of Lutzomyia longipalpis larvae and adults widely varies according to the substrate where eggs are laid (Martins et al, 2021). However, reduced microbiota diversity is observed in L. longipalpis infected by Leishmania infantum, suggesting that the parasite acts as an equalizer agent of the vector microbiota (Kelly et al, 2017).…”

Vector-borne diseases (VBDs) pose significant global health threats. The microbiota of arthropod vectors influences their fitness and pathogen acquisition and/or transmission. Here, we review the intricate interplay among the arthropod immune system, the microbiota, and pathogens that limits or favors infection. We focused on the most important arthropod vectors, namely mosquitos, phlebotomines, tsetse flies, triatomines, and ticks, and expanded our analysis to include the nonvector model Drosophila melanogaster for comparison. The microbiota and immune system of arthropod vectors are targets for the development of promising control strategies, such as paratransgenesis and anti‐microbiota vaccines. Further research should focus on elucidating the underlying mechanisms of vector–pathogen–microbiota interactions and optimizing anti-microbiota strategies. These approaches have the potential to combat VBDs and reduce their global impact.

The ground-dwelling invertebrate fauna from an urban park in Belém, Amazonian Brazil, with particular reference to the subfamily Phlebotominae (Diptera: Psychodidae), were characterized. Sampling was performed from March 2022 to May 2023, with 10 emergence traps installed in 2 microhabitats, 5 in each 1: “M1,” which included surrounding (up to 1.5 m) trees with tabular roots, and “M2,” which included no trees with tabular roots. Invertebrates trapped in adhesive papers were assessed on 2 occasions/cycles (D21/D42). During 10 sampling cycles (10 traps/cycle = 100 samples), 6,490 invertebrates were captured (M1, n = 4,203; M2, n = 2,287) and classified into 5 classes and 21 orders, with Diptera (n = 2,309; 35.6%) being the most abundant. Twenty-nine specimens of the following phlebotomine species were captured: Nyssomyia antunesi (M1, n = 10; M2, n = 3), Trichophoromyia ubiquitalis (M1, n = 6; M2, n = 1), Th. brachipyga (M1, n = 0; M2, n = 2), Bichromomyia flaviscutellata (M1, n = 2; M2, n = 1) and 4 unidentified specimens (M1, n = 2; M2, n = 2). The male/female ratio was 1.08. Fractional vegetation cover was compared, and the physiochemical characteristics of the soil were compared between the microhabitats. Only temperature showed significant differences. A weak positive correlation was found between phlebotomines and other dipterans and between temperature and the amount of organic matter in the soil. Both sampled microhabitats were shown to be suitable for the development and maintenance of different invertebrates, mainly dipterans. The composition of ground-emerging phlebotomine species was similar to that previously surveyed with light traps, including species associated with the transmission of Leishmania spp.

Sand Flies and Their Microbiota

Sand flies are a significant public health concern in many parts of the world where they are known to transmit agents of several zoonotic diseases to humans, such as leishmaniasis. Vector control remains a key component of many anti-leishmaniasis programs and probably will remain so until an effective vaccine becomes available. The sand fly gut microbiota has recently emerged as an encouraging field for the exploration of vector-based disease control. In particular, the gut microbiome was previously reported to either enhance or inhibit parasite activity depending on the species of bacteria and, thus, has the potential to alter vector competence. Here, we describe the technological advances that are currently expanding our understanding of microbiota composition in sand flies. The acquisition and composition of microbiomes are influenced by several abiotic and biotic factors, including host immunity, genetics, and the environment. Therefore, the microbiomes of sand flies can vary substantially between individuals, life stages, species, and over geographical space, and this variation likely contributes to differences in host phenotypes, highlighting opportunities for novel vector control strategies.
