BACKGROUND AND OBJECTIVES Epidemiology and transmission of malaria vary within the tribal areas with the variation in topography, forest cover and type of forest. For the control of disease, understanding of the dynamics of transmission in the varied ecological situation is essential. This study was carried out in the two distinct tribal areas- Baiga Chak (thick forested area) of Dindori distri...

Biolarvicides, based on mosquitocidal toxins of certain strains of Bacillus sphaericus and Bacillus thuringiensis var israelensis H-14 (Bti) are highly effective against mosquito larvae at very low doses and safe to other non-target organisms. During past two decades various biolarvicide formulations produced in India and abroad have been tested at Malaria Research Centre and some formulations ...

Studies conducted in Warangal, Khammam and Mahabubnagar districts in Andhra Pradesh and Surat district in Gujarat have revealed that Anopheles culicifacies sensu lato (s.l.) populations were resistant to malathion. In the absence of indoor spraying of malathion in public health programs in the 3 districts of Andhra Pradesh, resistance is attributed to the extensive use of pesticides in agricult...

The object of this short paper is to call attention to two facts?firstly, the finding of sporozoits in a variety of anopheles fuliginosus in the natural state; and, secondly, the variations to which a species is liable. Regarding the first point, recent study has shown that while many, if not all, anopheles may experimentally carry malarial infection, practically only two Indian species are kno...

Anopheles culicifacies sensu lato collected from Rameshwaram island, Tamil Nadu state, India was identified as species B based on the diagnostic inversion karyotype Xab 2g1+h1 as observed in polytene chromosomes. Among male mitotic karyotypes made from larval neurogonial cells, two types were observed: one with an acrocentric Y-chromosome and the other with a sub-metacentric Y-chromosome, both ...

In India National Vector Borne Diseases Control programme is an umbrella organization for management and control of six out eight insect-borne human diseases, viz., Malaria, Lymphatic Filariasis (LF), Kala-azar, Dengue/ Chikungunya, Japanese Encephalitis. Of these, committed elimination the first three diseases from country. 8.6% India’s total population belongs to tribal community yet contribu...

Malaria and other mosquito borne diseases are common in Kolkata, India. Among the 34 species of mosquitoes recorded from Kolkata, 13 are anophelines, of that Anopheles annularis Van der Wulp, An. culicifacies Giles, and An. stephensi Liston are established vectors of malaria1–3. The abundance of these vector mosquitoes varies with the season and available habitats2–4. Mobility of human hosts be...
