| Abstract | ||
| Despite tremendous efforts over the past century, malaria remains the major health burden in the state Odisha, India. In view of designing a situation specific malaria control strategy, baseline data on bionomics of major Anopheles vectors were collected from three malariogenical stratified districts of Odisha. A comparative study of vector abundance, seasonal prevalence, habit/habitats, resting sites preference, parity rate, proportion of human blood fed vectors and Anopheline species composition was established in a high (Kalahandi), moderate (Bargarh) and a low endemic (Cuttack) districts, when malaria transmission was at its peak level. The mosquito collection showed a wide range of Anopheline fauna diversification with collection of two efficient malaria vectors i.e. An. culicifacies, the primary vector with a high peak value during monsoon and An. annularis, the secondary vector in three study districts. Both vectors was significantly more in indoor than outdoor in the three districts and among indoor collections, the density was higher in CS than HD whereas the density was more in HD than CS in Cuttack district for annularis. Similarly, their feeding, biting pattern as well as parity rate varies among these districts. The molecular identification of An. culicifacies revealed the presence of all five sibling species viz. A, B, C, D & E whereas only species A was detected out of two sibling species A & B of An. annularis. These entomological indicators such as vector density, distribution, biology and bionomics as well as their vectorial attributes are important parameters to measure the pattern and intensity of malaria transmission. Proper monitoring and evaluation of these indices during the peak transmission period can reduce the increasing trend of malaria. | ||
