Estudo da densidade de bulinus - physopsis SPP em Boane

Abstract

The control of vectors responsible for the transmission of diseases is a measure that ensures greater efficiency in the treatment of patients. The knowledge of the places where these vectors are found can be used to plan campaigns to combat the vector as a way to reduce transmission foci. Based on the above, this study was designed, which has as its main objective: To estimate the density of Bn Hints (Physopsis) spp in two areas of the district of Boane. The district of Boane is located about 30 km from the city of Maputo. The study lasted approximately three months with harvests in the sampling areas every ten days. In both sampling areas there are conditions for the development of interniftliary host molluscs responsible for the transmission of vesical billiard-oziosis. At the time of shellfish harvests, the sampling areas showed significant differences with respect to standard deviation. Two techniques were used for mollusc harvesting, net capture and bait capture, the latter being the most effective and, consequently, recommended for fiture research. The main limitations of this work were: Short duration that did not allow for more conclusive results. Failure to obtain infected molluscs.
