Updated information on the distribution of Anopheles in the Valencian Autonomous Region of Eastern Spain is presented. Larval surveys over a four year period (20052008) detected seven species, all in the subgenus Anopheles, namely Anopheles algeriensis, An. atroparvus, An. claviger, An. maculipennis, An. marteri, An. petragnani and An. plumbeus. Distribution, biology and ecology of each are dis...

Aedes aegypti and Anopheles gambiae are among the best-characterized mosquito species within the Culicinae and Anophelinae mosquito clades which diverged ∼150 million years ago. Despite this evolutionary distance, the olfactory systems of these mosquitoes exhibit similar morphological and physiological adaptations. Paradoxically, mosquito odorant receptors, which lie at the heart of chemosensor...

En el presente trabajo se evaluó efecto de la temperatura sobre expresión fenotípica del tamaño, alargamiento (largo/ancho) y las manchas costales alas entre familias, progenies sexos, mediante morfometría tradicional en Nyssorhynchus triannulatus sur Colombia. 11 criadas a 20, 24 28 °C, presentaron cuatro patrones costales. El patrón I estuvo tres temperaturas como más frecuente. Dentro famili...

The Flavivirus genus encompasses several arboviruses of public health significance such as dengue, yellow fever, and Zika viruses. It also includes insect-specific flaviviruses (ISFs) that are only capable of infecting insect hosts. The vast majority of mosquito-infecting flaviviruses have been associated with mosquito species of the Aedes and Culex genera in the Culicinae subfamily, which also...

The discovery and mapping of cis-regulatory elements is important for understanding regulation of gene transcription in mosquito vectors of human diseases. Genome sequence data are available for 3 species, Aedes aegypti, Anopheles gambiae, and Culex quinquefasciatus (Diptera: Culicidae), representing 2 subfamilies (Culicinae and Anophelinae) that are estimated to have diverged 145 to 200 millio...

Traps are widely employed for sampling and monitoring mosquito populations for surveillance, ecological and fauna studies. Considering the importance of assessing other technologies for sampling mosquitoes, we addressed the effectiveness of Mosquito Magnet® Independence (MMI) in comparison with those of the CDC trap with CO2 and Lurex3® (CDC-A) and the CDC light trap (CDC-LT). Field collections...

High insecticide resistance resulting from insensitive acetylcholinesterase (AChE) has emerged in mosquitoes. A single mutation (G119S of the ace-1 gene) explains this high resistance in Culex pipiens and in Anopheles gambiae. In order to provide better documentation of the ace-1 gene and the effect of the G119S mutation, we present a three-dimension structure model of AChE, showing that this u...

17 The Flavivirus genus encompasses several arboviruses of public health significance 18 such as dengue, yellow fever, and Zika viruses. It also includes insect-specific flaviviruses 19 (ISFs) that are only capable of infecting insect hosts. The vast majority of mosquito-infecting 20 flaviviruses have been associated with mosquito species of the Aedes and Culex genera in the 21 Culicinae subfam...

The urban area of Dakar, Senegal, contains > 5,000 market-garden wells that provide permanent sites for mosquito larvae, in particular Anopheles arabiensis Patton, the major vector of malaria. A study of the bioecology of mosquito larvae was conducted over 1 yr with a monthly visit to 48 of these wells. Overall, 9,589 larvae were collected of which 80.1% were Culicinae and 11.9% Anophelinae. La...
