A possible alternative method for collecting mosquito larvae in rice fields

Published by National Institutes of Health | U.S. Department of Health & Human Services | Metadata Last Checked: September 06, 2025 | Last Modified: 2025-09-06
Background Rice fields are efficient breeding places for malaria vectors in Madagascar. In order to establish as easily as possible if a rice field is an effective larval site for anophelines, we compared classical dipping versus a net as methods of collecting larvae. Results Using similar collecting procedures, we found that the total number of anopheline larvae collected with the net was exactly double (174/87) that collected by dipping. The number of anopheline species collected was also greater with a net. Conclusions The net is an effective means of collecting anopheline larvae and can be used for qualitative ecological studies and to rapidly determine which rice fields are containing malaria vectors.
