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 This study was undertaken in two Primary Health Centers (PHCs) of malaria endemic district Jabalpur in Madhya Pradesh (Central India). METHODS In this study we had investigated the relative frequencies of the different anopheline species collected within the study areas by using indoor resting catches, CDC light trap and human landing methods. Sibling species of malaria vectors wer...

Follow-up studies were carried out from 1989 to 1998 after withdrawal of deltamethrin indoor spraying to evaluate the recovery rate of a population of Anopheles culicifacies resistant to dichlorodiphenyltrichloroethane (DDT) and hexachlorocyclohexane (HCH) in selected villages in Uttar Pradesh State, India. The study revealed 82.4-96.5% reduction in adult density of An. culicifacies and 72.7-96...

The presence of mosquito vectors Anopheles culicifacies and Anopheles stephensi in high numbers together with other malaria causing factors like poor drainage system, lack of knowledge about malaria, low socio-economic conditions etc has made malaria a major health burden in Rohtak and Mewat districts of Haryana. The primary objective of the study was to prepare thematic maps of six selected vi...

Anopheles pulcherrimus Theobald has a wide distribution in western Asia and is a potential vector of malaria in Iran. We have examined the rDNA-ITS2 (internal transcribed spacer 2) region of An. pulcherrimus specimens collected during the two peaks of activity (May-June and October-November) from Sistan and Baluchistan province, southeastern Iran. There were no consistent differences between sp...

Malaria in industrial complexes is promoted by extensive mosquitogenic potential generated by excavations and importation of parasite through migratory labor. The National Thermal Power Corporation (NTPC), Shaktinagar, Sonbhadra district was surveyed for malariogenic conditions from 1994 to 1996. The major mosquito breeding sites were drains, storm-water drains, lakes, outside tanks, overhead t...

BACKGROUND & OBJECTIVES Indoor residual spraying of Reldan 40% EC @ 0.5 and 1 g/m2 was done in Tatarpur and Chauna villages, respectively in Dhaulana PHC, Distt. Ghaziabad (U.P.) to evaluate its impact against Anopheles culicifacies and malaria incidence. Results were compared with that of Piyawali village which was taken as control area. METHODS Four rounds of spray were done from 1999--2000...

BACKGROUND & OBJECTIVES Efficacy of Olyset nets, long-lasting insecticidal nets were tested from August 2003 to August 2006 against Anopheles culicifacies, the vector which transmits 60% of all malaria cases in rural India. METHODS Three villages in District Gautam Budh Nagar (Uttar Pradesh), India were selected for the trial and Olyset nets were distributed in one village, in another village...
