Mosquito breeding and resting in treeholes in a forest ecosystem in Orissa.

During a longitudinal study in the deciduous monsoon forest in northwest Orissa, 16 species belonging to Genera Anopheles (2), Culex (3), Aedes (8), Armigeres (1), Orthopodomyia (1) and Toxorhynchites (1) were found breeding in the treeholes, while 20 species including disease vectors An. culicifacies, Cx. quinquefasciatus, Ae. albopictus, Cx. tritaeniorhynchus and Cx. vishnui were found resting. The study showed that so far malaria vectors have not exploited the breeding potential of treeholes but Aedes albopictus, vector of dengue/ dengue haemorrhagic fever in Asia, was one of the main species breeding and resting in the treeholes. The paper describes seasonality, interspecific association and some new species breeding/resting in treeholes in Orissa.

Seasonality of indoor resting mosquitoes in a broken-forest ecosystem of north-western Orissa.

The seasonal prevalence and indoor resting habits of mosquitoes in a broken-forest ecosystem of Orissa, which is known to be endemic for malaria and bancroftian filariasis, have been studied. A total of 15 anopheline spp., 9 Culex spp. and one each of Aedes, Armigeres and Mansonia, were collected. Major species with perennial occurrence were Anopheles culicifacies, An. subpictus, An. annularis, An. vagus, An. pallidus, An. nigerrimus, Culex quinquefasciatus and Cx. tritaeniorhynchus. These species rested more in cattlesheds than in human dwellings, except Cx. quinquefasciatus which was abundant in human dwellings. The prevalence and indoor resting pattern of different species in relation to seasons and other factors were also investigated.

Prevalence of malaria and economic loss in two major iron ore mines in Sundargarh district, Orissa.

A cross-sectional study on malaria was undertaken in May 1989 in the settlements of Kalta and Barsuan iron ore mines situated in a hilly area of Sundargarh district. Fever surveys revealed slide positivity rates of 33.9% and 34.8% in Kalta and Barsuan, respectively. Malaria infection rates as recorded through mass blood surveys in the resident population were 23.5 and 13.8%, respectively. Children up to 9 years age suffered most from malaria and in the age group of 2-9 years 37.3%, children had enlarged spleens with an average enlarged spleen (AES) index of 1.7. P. falciparum was the most prevalent species followed by P. vivax and P. malariae. Malaria vectors viz., An. fluviatilis and An. culicifacies were present in high densities. The present paper also brings out the economic loss due to malaria to the mining industry.
