Abstract
Objective: To study the effect of environmental parameters like humidity, rainfall and temperature on the dynamics of vectorial competence of An. culicifacies. Methods: Epidemiological data and climatological data were collected from state Govt. (Odisha). And the mosquito bionomics was studied in laboratory regression test of PMHD of An. culicifacies, SPR in relation to mean rainfall, mean humidity and mean temperature were done. Applications/Improvements: Linear regression test of the afore-mentioned and in addition to them mean humidity and SPR, mean humidity and PMHD showed positive correlation. Linear regression test of PMHD An. culicifacies and SPR of the study districts showed positive correlation with correlation coefficient value r2 = 0.88 and p value = 0.0006. Conclusion: The results proved the effect of the above mentioned parameters in malaria transmission by favoring vector biology and thus malaria endemicity. Keywords: Anopheles Culicifacies, Climatic Factors, Malaria Endemicity, Vector Bionomics, Vectorial Competence
Highlights
Malaria is a public health problem in India and creates severe roadblocks to its development[1]
Bionomics is that part of biology which deals with the relationships of a given species and its environment
The data on PMHD and the SPR of the An. culicifacies in the study districts are depicted in the following table
Summary
Malaria is a public health problem in India and creates severe roadblocks to its development[1]. Irrespective of climatic variation An. culicifacies is widely distributed in most states of India and has been recorded in all mainland zones including Kashmir and high elevations in the Himalayas (up to 3000 meters) except islands of Lakshadweep and Andaman and Nicobar It extends beyond India’s boundaries to Pakistan, Afghanistan, Iran, Yemen and Ethiopia to the west; to Bangladesh, Thailand, Myanmar, Laos and upto Vietnam to the East; to Nepal and Southern China in the North and upto Sri Lanka in the South[5,6,7]. It is the most important vector in plains of rural India contributing 60-70% of reported cases annually[7,8]. Bionomics is that part of biology which deals with the relationships of a given species and its environment
