The Colombian Pacific region is second nationally in number of malaria cases reported. This zone presents great ecological heterogeneity and Anopheles species diversity. However, little is known about the current spatial and temporal distribution of vector species. This study, conducted in three ecologically different localities of the Pacific region, aimed to evaluate the composition and distr...

The endosymbiotic bacterium Wolbachia is being investigated as a potential control agent in several important vector insect species. Recent studies have shown that Wolbachia can protect the insect host against a wide variety of pathogens, resulting in reduced transmission of parasites and viruses. It has been proposed that compromised vector competence of Wolbachia-infected insects is due to up...

Background & Aims of the Study: The aim of this study was to determine the ecology of malaria vectors in order to select the vector control masseur in the future. This study was carried out on trend of malaria cases and malaria vectors in Saravan county, Sistan & Baluchestan Province, Iran. Materials & Methods: The adult mosquitoes were collected by standard Pyrethrum space spray colle...

A total of 460 Anopheles funestus s.l. was collected inside human dwellings in Mwea, central Kenya. Of the 414 specimens that were positively identified, 1 was Anopheles leesoni and the others were Anopheles parensis. None of the 373 specimens tested were positive for Plasmodium falciparum or Plasmodium malariae sporozoites by enzyme-linked immunosorbent assay (ELISA). Of the 139 ELISA blood-me...

Understanding oviposition behavior is important to behavioral and vector ecologists because of its potential use in developing vector control strategies for insect-borne infectious diseases. Our study compared the oviposition behaviors of Anopheles gambiae s.s mosquitoes from two different regions of East Africa, Mbita Point, Kenya and Ifakara, Tanzania. The work sought behavioral evidence for ...

Malaria is still a primary health problem in Colombia. The locality of Tierradentro is situated in the municipality of Montelíbano, Córdoba, in the northwest of Colombia, and has one of the highest annual parasite index of malaria nationwide. However, the vectors involved in malaria transmission in this locality have not yet been identified. In this study, the local anthropophilic Anopheles com...

Background and objectives: Malaria is a remarkable cause of death in the world. Several ways are used by researchers to control or to decrease the detrimental effects of the disease, in which natural insecticides with less malaria vectors resistance and lower environmental damages are considered in last decades.The objective of this study was to assess the larvicidal activity of the whole flowe...

Quantitative reverse transcription PCR (qRT-PCR) has been an integral part of characterizing the immunity of Anopheles mosquitoes towards Plasmodium invasion. Two anti-Plasmodium factors of Anopheles, thioester-containing protein 1 (TEP1) and nitric oxide synthase (NOS), play a role in the refractoriness of Anopheles towards Plasmodium infection and are generally expressed during infection. How...

Artemisinin-resistant Plasmodium falciparum parasites are rapidly spreading in Southeast Asia, yet nothing is known about their transmission. This knowledge gap and the possibility that these parasites will spread to Africa endanger global efforts to eliminate malaria. Here we produce gametocytes from parasite clinical isolates that displayed artemisinin resistance in patients and in vitro, and...
