AI Article Synopsis
- Sugar and cellulose assays can indicate if insects like Phlebotomus papatasi have fed on sugars or plant tissues, but can't specify the plant species.
- In a study conducted in the Lower Jordan Valley, researchers combined DNA analysis with these assays to better understand what these sand flies are feeding on.
- Findings revealed that 37% of the flies contained sugar, 45% showed cellulose, and 41% had detectable plant DNA, with the DNA primarily matching the plant Suaeda asphaltica.
Article Abstract
Sugar and cellulose assays can determine if an insect has fed on sugar and plant tissue but they cannot identify the species of source plant. In this study, we used DNA analysis together with traditional cellulose and sugar assays to examine the plant feeding habits of wild Phlebotomus papatasi during the dry season in the Lower Jordan Valley, Israel. About 37% of the sand flies were positive for sugar, 45% were positive for cellulose in the gut, and 41% contained amplifiable plant DNA. All of the plant DNA fragments sequenced from both males and females were identified as Suaeda asphaltica.

Sandflies, small insects primarily from the Psychodidae family, are commonly found in sandy, tropical, and subtropical regions. Most active during dawn and dusk, female sandflies feed on blood to facilitate egg production. In doing so, they can transmit infectious diseases that may cause symptoms such as fever, headaches, muscle pain, anemia, skin rashes, and ulcers.

Leishmaniasis is currently considered a major health problem in Iran, posing an increasing threat to society's development in various dimensions. This study aimed to detect infection in wild-caught sand flies in Sari City, northern Iran. Sand flies were collected using sticky traps, and DNA was identified using polymerase chain reaction (PCR) targeting the ITS2-rDNA region, followed by restriction fragment length polymorphism (RFLP) analysis.

Article Synopsis
- * The study analyzed trapping data for eight sand fly species across seven countries, revealing varied meteorological limits for each species' activity based on factors like temperature and precipitation.
- * Findings indicate that some species, like Phlebotomus balcanicus, have broader tolerances to weather changes, while others are more sensitive, helping to identify important ecological niches and support targeted surveillance efforts against pathogen spread.

Early interactions between Leishmania-macrophages (MQ) of host and effect of sand fly saliva are central to leishmaniasis outcome. Macrophages are able to kill or act as long-term hosts of parasite depending on host immunity. It proved that immunogenic proteins in sand fly saliva mostly have an exacerbating effect on leishmaniasis by up-regulating cytokines.

India is accelerating efforts to eliminate kala-azar by aligning its National Kala-Azar Elimination Program with the World Health Organization's (WHO) roadmap for Neglected Tropical Diseases (NTDs) 2021-2030. Elimination relies on comprehensive vector surveillance and integrated vector management. This study aimed to conduct nationwide entomological surveillance to detect Leishmania donovani in phlebotomine sand flies.
