Blood Meal Preference of Some Anopheline Mosquitoes in Command and Non-command Areas of Rajasthan, India

Background: The present study was undertaken to compare the entomological situation by analyzing the bloodmeal of mosquitoes of canal irrigated and non-irrigated areas of Bikaner in order to explore scientific information onthe vector biology and malaria burden profile and to plan proper strategies for malaria control and eradication.Methods: Adult mosquitoes were collected and the abdomen of the blood fed females were crushed on a filter paperfor blood meal analysis and subjected to precipitin test.Results: The blood meal analysis showed that Anopheles subpictus had a preference towards cattle blood, An.culicifacies and An. stephensi preferred human blood, while, An. annularis was noted to feed only on bovine blood.Conclusion: Although An. annularis, has been recently reported from the area, was found to feed exclusively onbovine blood, earlier reports suggest that this species is a vector of malaria and therefore preventive measuresshould be taken well in advance before this species gets established in the area.
