BACKGROUND Anopheles culicifacies, the main vector of human malaria in rural India, is a complex of five sibling species. Despite being phylogenetically related, a naturally selected subgroup species B of this sibling species complex is found to be a poor vector of malaria. We have attempted to understand the differences between vector and non-vector Anopheles culicifacies mosquitoes in terms o...

BACKGROUND & OBJECTIVES An alarming rate of deforestation has been reported from Sonitpur district of Assam, India therefore, a study was initiated during 2009 using remote sensing (RS) to assess deforested areas in the district and to study the impact on malaria vectors in order to formulate appropriate control strategy. METHODS RS imageries of 2000 and 2009 were used to assess deforested ar...

BACKGROUND & OBJECTIVES The major malaria vector, Anopheles culicifacies Giles is reported to contribute ~ 65% of the malaria cases in India. This species developed resistance to DDT and later to HCH, malathion and also to pyrethroids in some states due to their use in the national malaria control programme. In the present study, insecticide susceptibility of this species was monitored in four ...

BACKGROUND & OBJECTIVES Malaria has become endemic and subject of concern in most part of the India especially Northeastern states of India. Surveys before 2000 revealed that Anopheles minimus was major vector responsible for transmission of malaria in this region followed by An. dirus and An. fluviatilis. However, recent studies indicate replacement of An. minimus vector by An. culicifacies du...

anopheles culicifacies is the vector of malaria in southeastern part of iran, india, west pakistan and ceylon. in 1959 the lc50 % ddt in the panchmahal district of gujarat state (india) had increased. ddt resistant population of a. culicifacies has been reported from west pakistan, burma and iran. after application of ddt in 1959, the density of a. culicifacies decreased sharply. the susceptibi...

BACKGROUND & OBJECTIVES Jharkhand is one of the highly malaria endemic states in India and experiencing vast ecological and human-induced changes over the years. These changes have provided more favourable conditions for malaria transmission in the region. The present study was carried out to find out the distribution and prevalence of anopheline vector and non-vector species in District Ramgar...

Hexane extract of tuber of plant Cyperus rotundus (Cyperaceae) was screened under laboratory conditions for repellent activity against mosquito vector Anopheles culicifacies Giles species A (Diptera: Culicidae), Anopheles stephensi Liston (Diptera: Culicidae), and Culex quinquefasciatus Say (Diptera: Culicidae). The Cyperus rotundus tuber extract was used to determine their effect on mosquito v...

A 2-site immunoradiometric assay (IRMA) was performed on the head and thorax of Anopheles culicifacies s.l. and An. pulcherrimus females, the 2 most common anopheline species in the District of Ghassreghand (Baluchistan, Iran), collected during the 2 peak malaria transmission seasons (May and September-October 1991). Positive IRMA results revealed the 2 species as potential vectors of malaria i...

The study was undertaken in eight endemic districts of Orissa, India, to find the members of the species complexes of Anopheles culicifacies and Anopheles fluviatilis and their distribution patterns. The study area included six forested districts (Keonjhar, Angul, Dhenkanal, Ganjam, Nayagarh and Khurda) and two non-forested coastal districts (Puri and Jagatsingpur) studied over a period of two ...
