The presence of Anopheles (Nyssorhynchus) dunhami Causey in Colombia (Department of Amazonas) is confirmed for the first time through direct comparison of mtDNA cytochrome c oxidase I (COI) barcodes and nuclear rDNA second internal transcribed spacer (ITS2) sequences with topotypic specimens of An. dunhami from Tefé, Brazil. An. dunhami was identified through retrospective correlation of DNA se...

district of jiroft is situated in south-east of iran which is one of the malarious regions. anopheles stephensi is considered as one of the main malaria vector in this region. ecology of this species was studied in the area to understand its vector behavior for implementation of effective vector control measures. different methods like total catch, pit shelter, night bite collection on human an...

background: plant extracts and oils may act as alternatives to conventional pesticides for malaria vector control. the aim of this study was to evaluate the larvicidal activity of essential oils of three plants of apiaceae family against anophe­les stephensi , the main malaria vector in iran. methods: essential oils from heracleum persicum , foeniculum vulgare and coriandrum sativum seeds were ...

The coalescent revolutionised theoretical population genetics, simplifying, or making possible for the first time, many analyses, proofs, and derivations, and offering crucial insights about the way in which the structure of data in samples from populations depends on the demographic history of the population. However statistical inference under the coalescent model is extremely challenging, ef...

on the range of malaria-infected mosquitoes is a practical point that seems worth recording. Stephens and Christophers (1902, Rep. Malaria Committee, Roy. Soc., 7th Ser.) investigating Anopheles culicifacies failed to find mosquitoes 600 yards from extensive breeding places. This observation has been confirmed by more recent investigators and it is generally acknowledged that the flight of this...

Anopheles female mosquitoes can transmit Plasmodium, the malaria parasite. During their aquatic life, wild Anopheles mosquito larvae are exposed to a huge diversity of microbes present in their breeding sites. Later, adult females often take successive blood meals that might also carry different micro-organisms, including parasites, bacteria, and viruses. Therefore, prior to Plasmodium ingestio...

BACKGROUND & OBJECTIVES Correct vector identification is an important task in the planning and implementation of malaria vector control programmes. This study was designed to provide baseline information on the species composition and distribution of members of the Anopheles gambiae complex in three eco-vegetational zones in Bayelsa state, Nigeria. METHODS Adult mosquitoes were collected by p...

BACKGROUND Orang Primary Health Centre (OPHC) and Balipara Primary Health Centre (BPHC) of Assam (India) report mosquito borne diseases annually. Current study was performed to ascertain the prevalence of known malaria and Japanese Encephalitis (JE) vectors and their possible role in disease transmission. METHODS Malaria epidemiological data for 2006-2010 and JE data for 2008-2013 of Assam, I...

The effectiveness of light, 1-octen-3-ol (octenol), carbon dioxide (CO2) and a combination of CO2 and octenol were compared as mosquito attractants using encephalitis vector surveillance traps in 2 villages in Madang Province, Papua New Guinea (PNG). Five species were collected, Anopheles koliensis, Anopheles farauti 2, Anopheles farauti 4, Anopheles longirostris, and Anopheles bancroftii. Ligh...
