Latest Research on Culicidae: Dec – 2019

The Mosquitoes of the South Pacific (Diptera, Culicidae)

This is an interesting work of scholarship and industry, beautifully, almost lavishly produced. the 2 volumes together weigh over seven pounds and when open cover an area of twenty-two by 18 inches. The work is primarily a really thorough taxonomic revision of the South Pacific mosquitoes, with summaries of all relevant biological information. the world covered stretches from the Solomon Islands within the north west to New Zealand within the south, and eastwards to the Marquesas and Easter Island. There are descriptions of 189 species (thought to be only a fraction of truth total) of which 76 are new, though 23 of those aren’t given formal names as they’re insufficiently known. [1]

Mosquitoes (Culicidae)

Culicidae, the mosquito family, is comprised of 41 recognized genera incorporating about 3,500 species, many of which are vectors of disease pathogens that have afflicted humans and livestock for hundreds of years, with devastating consequences for tens of many people. These include the well-known human diseases malaria, filariasis, encephalitis, yellow jack, and dengue, but there are many others of medical or veterinary importance. Complicating matters, many of the human pathogens are shared with wild animal reservoirs. additionally, mosquitoes are annoying, explanation for allergies, or cause significant blood loss once they occur in large numbers, thanks to their bites alone. As a gaggle, mosquitoes sleep in almost every conceivable environment where water occurs, a necessity for his or her larval development. [2]

Sensilla of Mosquitoes (Diptera: Culicidae)

Almost all of the peripheral sensilla, including the compound eyes, of both sexes of adult yellow-fever mosquito are described at the spectrum line level. More is understood about the structure of the sensilla of Ae. aegypti than for the other insect. The spectrum line of antennal and palpal sensilla of both sexes of Anopheles stephensi has also been thoroughly described. the amount of neurons composing the flagellar and antennal nerves of both sexes of Ae. aegypti and An. stephensi has been determined. the interior morphology of the antennal small sensilla coeloconica of both sexes of Toxorhynchites brevipalpis and Deinocerites cancer and tarsal and labellar chemosensilla of female Culiseta inornata has been described from transmission microscopy work.

Elevated atmospheric CO2 promoted speciation in mosquitoes (Diptera, Culicidae)

Mosquitoes are of great medical significance as vectors of deadly diseases. Despite this, little is understood about their evolutionary history or how their present day diversity has been shaped. Within a phylogenetic framework, here we show a robust correlation between global climate change and mosquito speciation rates: the primary time to our knowledge such an impact has been demonstrated for insects. scientific theory reveals that although global climate change is correlated with mosquito evolution there are other important factors at play. We identify one such driver to be the increase of mammals, which are predominant hosts of Culicidae. [4]

The Fauna, Habitats and Medically Importance of Mosquito Larvae (Diptera: Culicidae) in Salfit District- Palestinian State

Aim: This study was conducted to debate the mosquito fauna, breeding sites and its habitat during January 2017 to May 2018 at Salfit district (Northwestern West Bank).

Study Design: A cross-sectional study

Methods: A cross-sectional survey was conducted in West Bank -Salfit District to gather mosquito larvae from January 2017 to May 2018.

Results: Six species of the Culicidae were collected belonging to four genera (Anopheles claviger, Asian tiger mosquito, common mosquito, Culex perexiguus, Culex laticinictus and Culiseta longiareolata) were recorded from Salfit District. Cu. longiareolata, Cx. laticinictus and Cx. pipiens were the foremost collected species. Anopheles claviger was reported for the primary time from Salfit District. [5]
