Abstract
BackgroundRice 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.ResultsUsing 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.ConclusionsThe 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.
Highlights
The role of rice fields as breeding places for anophelines has already been established in the highlands of Madagascar [1–3] (Figure 1 and 2)
Materials and Method The first method was based on the classical dipping method with a white tray (20 x 15 x 3 cm) [4] (Figure 3)
The net was drawn through the water until it became clogged with particles and sludge. It was removed from the water and emptied into a large white tray (30 x 22 x 4 cm)
Summary
The role of rice fields as breeding places for anophelines has already been established in the highlands of Madagascar [1–3] (Figure 1 and 2). The method of collecting anopheline larvae in rice fields has not been addressed. We compared two simple methods to determine which was the most efficient way to collect anopheline larvae from the rice fields. Rice fields are efficient breeding places for malaria vectors in Madagascar. In order to establish as 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
