BACKGROUND & OBJECTIVES Balaghat district in Central India is a highly malarious district where both Plasmodium falciparum and P. vivax are prevalent. In this district, the persistence of malaria was on an increase and not responsive to intervention measures even though there was no drug resistance. This study was undertaken by conducting mass screening to determine the prevalence of malaria am...

Seventy-six sites characterized in Amazonian Brazil revealed distinct habitat diversification by examining the environmental factors associated with the distribution and abundance of five anopheline species (Diptera: Culicidae) in the subgenus Nyssorhynchus. These included three members of the Albitarsis Complex, Anopheles oryzalimnetes, Anopheles marajoara, Anopheles janconnae, Anopheles trian...

Results of a recent survey of the 3 species of Anopheles mosquitoes, Anopheles (Nyssorhynchus) aquasalis, Anopheles (Nyssorhynchus) argyritarsis, and Anopheles (Anopheles) pseudopunctipennis, on the island of Grenada are contrasted with the only other published survey of these species on Grenada, which was published in 1938. Results suggest that a significant change in the abundance and distrib...

on the range of malaria-infected mosquitoes is a practical point that seems worth recording. Stephens and Christophers (1902, Rep. Malaria Committee, Roy. Soc., 7th Ser.) investigating Anopheles culicifacies failed to find mosquitoes 600 yards from extensive breeding places. This observation has been confirmed by more recent investigators and it is generally acknowledged that the flight of this...

BACKGROUND & OBJECTIVES Most of autocidal control of malaria vectors relies on the rearing and release of large numbers of sterile male into a wild population and it would be crucial to separate the males from females before release. This could result in enormous economic benefits in the mass rearing and raise the efficiency of the field operations. The development of genetic sexing of mosquito...

BACKGROUND & OBJECTIVES The relationship between altitude, temperature and malaria are poorly understood. Hence, a study was undertaken at three sites of Udham Singh Nagar (erstwhile Nainital district) and Nainital district (Uttarakhand) during 2010- 11 for the generation of evidences in the context of potential threat of climate change. METHODS Data on temperature and relative humidity (RH) ...

Anopheles malefactor Dyar and Knab is elevated from synonymy with An. punctimacula Dyar and Knab, and both species are described and illustrated. Primary morphological differences in the adult, pupal, and larval stages are provided for the separation and recognition of these species. An. punctimacula occurs from Mexico to northern Colombia and Venezuela, whereas An. malefactor is restricted to ...

Malaria is still a primary health problem in Colombia. The locality of Tierradentro is situated in the municipality of Montelíbano, Córdoba, in the northwest of Colombia, and has one of the highest annual parasite index of malaria nationwide. However, the vectors involved in malaria transmission in this locality have not yet been identified. In this study, the local anthropophilic Anopheles com...

Metaphase karyotypes of 9 species of the Myzomyia Series show intra- and interspecific differences based on quantitative variation and distribution of constitutive heterochromatin in the sex chromosomes or the centromeric regions of the autosome pairs or both. Anopheles jeyporiensis and Anopheles aconitus each exhibit 4 forms of mitotic karyotypes, which may reflect interspecific differences wi...
