Abstract

Mosquito borne diseases have a great impact on human and animal health throughout the world including Bangladesh. An entomological survey was conducted at the Bangladesh Agricultural University (BAU) campus and its surrounding areas from January to June, 2013 to identify the mosquito larvae and to investigate the different breeding site preferences of mosquitoes. Mosquito larvae were collected using dipper, ladle spoon, dropper and pipette from rice field, botanical garden, dairy farm, poultry farm, drains, lakes, ponds, staff quarters, residential halls and cattle sheds. A total of 1397 mosquito larvae were collected from the places. Ten species of mosquitoes under three genera were identified. The recorded genera were Anopheles (An.), Culex (Cx.) and Aedes (Ae.). The collected species were An. bengalensis, An. vagus, Cx. fuscocephala, Cx. quinquefasciatus, Cx. tritaeniorhynchus, Cx. gelidus, Cx. vishnui, Cx. whitmorei, Cx. sitiens and Ae. albopictus. Among the collected larvae, Culex was found most prevalent (64.3%), followed by Anopheles (26.7%) and Aedes were the least prevalent (9.0%). The results of this study provide evidence that drains were the most common aquatic habitat of Anopheles and Culex larvae in Boyra, Kewatkhali and Balashpur. In BAU campus, agronomy fields were found having the highest percentage (35.2%) of mosquito larvae than the other places of the campus. This study suggests that although drains and rice fields are the richest habitats, since Anopheles and Culex can breed in all available breeding habitats. This larval survey will help us to conduct future mosquito control activities and provide us useful information to schedule larvicides application to control the mosquito borne diseases in the study areas as well as throughout the country.
