Human antibody (Ab) response to Anopheles whole saliva, used as biomarker of Anopheles exposure, was investigated over a period of two years (2008-2009), in children between 2 to 9 years old, before and after the introduction of three different malaria vector control methods; deltamethrin treated long lasting impregnated nets (LLIN) and insecticide treated plastic sheeting (ITPS)--Zero Fly®) (I...

Malaria parasite ookinetes must traverse the vector mosquito midgut epithelium to transform into sporozoite-producing oocysts. The Anopheles innate immune system is a key regulator of this process, thereby determining vector competence and disease transmission. The role of Anopheles innate immunity factors as agonists or antagonists of malaria parasite infection has been previously determined u...

In Southeast Asia the biodiversity of Anopheles species in the domestic environment is very high. Only few species are considered major vectors throughout the region, whereas the vector status of other species varies from area to area. Often it is difficult to identify an Anopheles species as a malaria vector in areas with low malaria incidence. The behaviour of Anopheles species largely determ...

During a longitudinal study on vector biology and malaria transmission in western Venezuela the degree of attraction of mosquitoes to 4 people who carried out landing catches was evaluated. An analysis of variance of the log(x + 1)-transformed data showed that there were no significant differences in attractiveness of various individuals to Anopheles nuneztovari, Anopheles marajoara, or Anophel...

Remote Sensing and Geographic Information System was used to develop a spatial risk malaria distribution model based on environmental suitability for survival of the Anopheles gambie sp. Complex (A. arabiensis and A. gambae), the vector known to transmit malaria in Zimbabwe (Masendu, 1996). Employing geostatistical techniques, spatial analysis of environmental factors that contribute to the spr...

Background & Aims of the Study: Malaria is an infectious disease by fever, chills and anemia; and splenomegaly genus Plasmodium parasite is the agent of it. One of the easiest and least expensive methods for preventionof this disease is removing the vector that usually has been done by insecticides and chemical pesticides, but now days due to the harmful effects of toxic chemic...

The 3-hydroxykynurenine transaminase (3-HKT) gene plays a vital role in the development of malaria parasites by participating in the synthesis of xanthurenic acid, which is involved in the exflagellation of microgametocytes in the midgut of malaria vector species. The 3-HKT enzyme is involved in the tryptophan metabolism of Anophelines. The gene had been studied in the important global malaria ...

Seventy-six sites characterized in Amazonian Brazil revealed distinct habitat diversification by examining the environmental factors associated with the distribution and abundance of five anopheline species (Diptera: Culicidae) in the subgenus Nyssorhynchus. These included three members of the Albitarsis Complex, Anopheles oryzalimnetes, Anopheles marajoara, Anopheles janconnae; Anopheles trian...

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...
