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...

Seasonal abundance and tendency to feed on humans are important parameters to measure for effective control of malaria vectors. The objective of this study was to describe relation between feeding pattern, abundance, and resting behavior of four malaria vectors in southern Iran. This study was conducted in ten indicator villages (based on malaria incidence and entomological indices) in mountain...

BACKGROUND Anopheles culicifacies is a main malaria vector in southeastern part of Iran, bordring Afghanistan and Pakistan. So far, resistance to DDT, dieldrin, malathion and partial tolerance to pyrethroids has been reported in An. stephensi, but nothing confirmed on resistance status of An. culicifacies in Iran. METHODS In current study, along with WHO routine susceptibility test with DDT (...

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 ...

BACKGROUND & OBJECTIVES A new irrigation canal system is under construction in Dhenkanal district of Odisha, to increase the production of rice crop and thereby improve the living standard of farmers in the project area. Construction of canal may increase the transmission of malaria by creating vector breeding habitats. Knowledge about bionomics of vectors will support authorities for appropria...

BACKGROUND & OBJECTIVES Several studies have been made to study the effect of antisera raised against different tissues (hemolymh, ovary, midgut and salivary glands) on the fecundity and malaria parasite development in the different species of mosquitoes but there are no reports on the antisera raised against the hemolymph of Anopheles culicifacies, the principal malaria vector in India account...

BACKGROUND Second internal transcribed spacer (ITS2) has proven to contain useful biological information at higher taxonomic levels. OBJECTIVES This study was carried out to unravel the biological information in the ITS2 region of An. culicifacies and the internal relationships between the five species of Anopheles culicifacies. METHODOLOGY In achieving these objectives, twenty two ITS2 seq...

899 Abstract The maxillary stylets and maxillary palps of three species of mosquitoes belonging to genus Anopheles, viz., Anopheles culicifacies Giles, Anopheles fluviatilis James Anopheles subpictus Grassi have been studied using scanning electron microscope. The studies reveal the presence of lateral teeth and absence of mesial teeth on the maxillary stylets. The number, shape and size of lat...

The present study explored the phylogenetic utility of mt-ND5 gene sequences for mosquitoes in genus Anopheles. Phylogenetic tree employing the Maximum Parsimony methods in PAUP strongly supported the traditional taxonomy of genus. Subgenus Anopheles represented by a single species i.e. Anopheles nigerrimus initially separated out from the rest with a strong bootstrap value of 100. Subgenus Cel...

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...
