Culex (Melanoconion) dureti Casal & García, 1968 was described based on the adult male. In this article, we describe and illustrate the pupa and the fourth-instar larva and provide a redescription of the adult male. Diagnostic characters of the male genitalia and fourth-instar larva are also provided to separate Cx.

Article Synopsis
  • The genus Flavivirus includes around 80 viruses, categorized by their transmission methods, primarily through mosquitoes and ticks, or as insect-specific flaviviruses.
  • Researchers investigated insect-specific flaviviruses in Argentina by analyzing the NS5 protein gene in mosquitoes from Córdoba, Chaco, and Tucumán, finding 68 out of 1776 pools positive for viruses like CxFV, KRV, and CFAV.
  • A significant presence of CxFV was detected across various mosquito species in northern and central Argentina, with strains showing genetic links to those found in other countries, highlighting potential public health risks due to interactions with pathogenic flaviviruses.

Community participation is a critical element in the management of Aedes aegypti and Aedes albopictus breeding sites. Many educational interventions have been conducted to encourage prevention and elimination of breeding sites among different community actors, such as government-run programs for vector surveillance aimed at preventing and eliminating breeding sites at the household level within a community. Getting people involved in prevention and elimination of vector breeding sites in their communities requires communication and social mobilization strategies to promote and reinforce those prevention actions that, in turn, should be effective from the entomological standpoint.

St. Louis encephalitis virus (SLEV) is endemic in the Americas and its transmission networks involve Culex mosquitoes and avian species. In 2015, a human encephalitis outbreak took place in Arizona and California, indicating the re-emergence of this pathogen in the US.

There is substantial evidence showing that temperature have a great impact on insects behavior, phenology and life histories. Because of mosquito global importance as disease vectors, in temperate regions where climatic conditions could be only borderline suitable for mosquito development, there is a growing interest in understanding the effect of temperature shifts on vital statistics to more accurately define how such changes could impact distribution and abundance patterns, as well as disease transmission cycles. We determined the role of ambient temperature under fluctuating conditions in shaping (Diptera: Culicidae) life history traits, and estimated its development threshold and physiological time, in its southern limit of distribution in the Argentine Patagonia region.
