Millions of people die each year as a result of pathogens transmitted by mosquitoes. However, the morphological identification of mosquito species can be difficult even for experts. The identification of morphologically indistinguishable species, such as members of the Anopheles maculipennis complex (Diptera: Culicidae), and possible hybrids, such as Culex pipiens pipiens/Culex pipiens molestus...

Anopheles (Nyssorhynchus) albitarsis sensu lato is an important malaria vector in Brazil, especially in the Brazilian Amazon region. Chromosome preparations of fourth-instar larvae of A. albitarsis from Iranduba and Coari (AM) and Ilha Comprida (SP) were analyzed for karyotype determination and to improve cytogenetic identification of this species. Anopheles albitarsis possesses 2n = 6 chromoso...

Dirofilaria immitis preferably infects canids and can, in lower frequency, be found in cats (Felis catus Linnaeus, 1758). The parasite may be transmitted by various Culicidae species. Motivated by an autochtone feline heartworm case diagnosed in the region of Engenho Novo - RJ (S 22 degrees 90' e WO 43 degrees 27'), the following issues were surveyed: 1) the local Culicidae fauna and; 2) the oc...

The attract-and-kill strategy is a new pest management technique that presupposes the intelligent combination of an attracting agent (e.g. pheromone) and a killing agent (e.g. insecticide). In the present study, the potential combination of the microencapsulated synthetic oviposition pheromone 6-acetoxy-5-hexadecanolide with an insecticide has been tested. Initially, polyurea microcapsules cont...

Abstract Mormodica charantia (Curcubitaceae) is a plant with great medicinal potential, also used as an alternative of mosquitoes control demonstrated by previous studies. We evaluated the larvicidal activity crude extracts ethyl acetate, methanol and hexane from flowers fruits M. against Aedes aegypti (Culicidae). Flowers were macerated in methanol, acetate hexane. Bioassays performed applicat...

Anopheles subpictus Grassi s.l. (Diptera: Culicidae) functions as a secondary malaria vector to Anopheles culicifacies Giles s.l. (Diptera: Culicidae) in Sri Lanka. The taxon A. subpictus is reported to exist as a species complex comprising four sibling species (A-D) that can be differentiated through polytene chromosome banding patterns and stage-specific morphometric traits in India. Based on...

BACKGROUND There are unorganized, published documents about the ecology of mosquitoes (Diptera: Culicidae) in northeastern part of Iran. The purpose of this study was to determine the distribution and characteristics of larval habitats of Culicidae in Kalaleh County. METHODS Larvae were collected using dipping method and adults by human landing catch technique during April-October, 2012. Larv...

In view of the high circulation of migratory birds and the environmental and climatic conditions which favor the proliferation of arthropods, the Brazilian Pantanal is susceptible to circulation of arboviruses. However, the amount of data concerning arbovirus vectors in this area is scarce; therefore the aim of this study was to conduct a preliminary investigation of Culicidae species in the Nh...

The invasive Asian tiger mosquito Aedes albopictus (Diptera: Culicidae) was first reported in central Africa in 2000, in Cameroon, with the indigenous mosquito species Ae. aegypti (Diptera: Culicidae). Today, this invasive species is present in almost all countries of the region, including the Central African Republic (CAR), where it was first recorded in 2009. As invasive species of mosquitoes...
