Introduction: This study aimed to evaluate the susceptibility of Anopheles darlingi Root (1926) and Anopheles marajoara Galvão & Damasceno (1942) to pyrethroids used by the National Malaria Control Program in Brazil.
Methods: Mosquitoes from Amapá, Brazilian Amazon, were assessed for resistance to cypermethrin, deltamethrin, and alpha-cypermethrin. Insecticide-impregnated bottles were used as suggested by the CDC/Atlanta.
Results: Diagnostic dose for Anopheles darlingi was 12.5µg/bottle during 30 min of exposure. Concentrations for Anopheles marajoara were 20µg/bottle of cypermethrin and deltamethrin and 12.5µg/bottle of alpha-cypermethrin.
Conclusions: No resistance was recorded for Anopheles darlingi , but Anopheles marajoara requires attention.

Large-scale surveillance and informed vector control approaches are urgently needed to ensure that national malaria programs remain effective in reducing transmission and, ultimately, achieving malaria elimination targets. In South America, Anopheles darlingi is the primary malaria vector and is responsible for the majority of Plasmodium species transmission. However, little is known about the molecular markers associated with insecticide resistance in this species.

Article Synopsis
- * Researchers collected water samples from eight sites and isolated 206 fungal strains, grouping them into 30 different morphotypes.
- * Fungi were identified through microscopy and DNA sequencing, revealing a predominance of Ascomycota, and significantly advancing our understanding of fungi in mosquito breeding habitats.

species composition, abundance, and natural infection are important aspects to assess malaria transmission risk. In this study, these aspects were evaluated in a large number of localities in the most important malaria-endemic regions of Colombia. Mosquitoes were collected from 2012 to 2015 in 55 localities of northwestern and western Colombia.

The characterization of non-retroviral integrated RNA virus sequences (NIRVS) in mosquitoes has emerged as a significant area of research that could yield insight into virus-host interactions. This study aimed to characterize NIRVS in the Anopheles darlingi reference genome and identify putative transcribed NIRVS in field-collected mosquitoes from Colombia. The An.

Objectives: The World Health Organization recommends three drug anti-malarial combinations: cloroquine+primaquine, artesiminin+primaquine, and cloroquine+tafenoquine. These combinations aim to eradicate Plasmodium by disrupting its life cycle within the human body. We evaluated the effect of these medications on the vectorial competence of two main vectors in the New World.
