Countercurrent immunoelectrophoresis was used to assay bloodmeals to determine the hostspecificity of Anopheles culicifarics species-A and B, collected from areas in Delhi, Uttar piadesh and Bihar. Results indicated the-predominantly zoophagic nature of species A and B with " r.t"tiullv higher degree of anthropophagy for species A. Furth-er, the human blood index was found to be relatei to the ...

BACKGROUND Anopheles culicifacies, a major malarial vector has been recognized as a complex of five sibling species, A, B, C, D and E. These sibling species exhibit varied vectorial capacity, host specificity and susceptibility to malarial parasites/ insecticides. In this study, a PCR assay developed earlier for distinguishing the five individual species was validated on samples of An. culicifa...

Understanding the molecular basis of mosquito behavioural complexity plays a central role in designing novel molecular tools to fight against their vector-borne diseases. Although the olfactory system plays an important role in guiding and managing many behavioural responses including feeding and mating, but the sex-specific regulation of olfactory responses remain poorly investigated. From our...

Cytogenetic observations on an extensive material of the Anopheles culicifacies complex from the Thenpennai river area, Tamil N adu, South India show that the populations are made up of four cytologically distinct species. Three of these, labeled A, B and C have already been described. A fourth .one, monomorphic for the inversion arrangement + a + b in the X chromosome and il + hI in the second...

Coarse Particles and Dust Storm Mortality In a paper titled "Episodes of High Coarse Partide Concentrations Are Not Associated with Increased Mortality," Schwartz et al. (1) concluded that "coarse particles from windblown dust are not associated with mortality risk." The authors seem to have overlooked the medical literature on the health effects of the historic U.S. dust storms of the dust bow...

We show that strictly abnormal geodesics arise in graded nilpotent Lie groups. We construct such a group, for which some Carnot geodesics are strictly abnormal and, in fact, not normal in any subgroup. In the 2-step case we also prove that these geodesics are always smooth. Our main technique is based on the equations for the normal and abnormal curves, that we derive (for any Lie group) explic...

A focal outbreak of malaria at Bonta sub-centre of PHC Kilvani, the UT of Dadra & Nagar Haveli was reported during the month of August, 2014. Seven villages of the above block were affected. During the episode, around 757 fever cases were reported with Slide Positivity Rate (SPR) of 11.6%. The malaria epidemiological data for last three years from the subcentre area indicates that the area is e...

The results of Ross (1936), De Meillon (1936), Covell et al. (1938), Russell and Knipe (1939, 1940, 1941), and Russell et al. (1942) leave no doubt that wherever the mosquito vector of malaria spends its daytime hours inside houses, cowsheds, or outbuildings, routine spraykilling with pyrethrum sprays will effectively interrupt the transmission of malaria. This measure is based on the principle...
