Abundant <i>Aedes</i> (<i>Stegomyia</i>) <i>aegypti aegypti</i> mosquitoes in the 2014 dengue outbreak area of Mozambique

In early 2014, dengue cases werereported from the northern Mozambique, 30 years since the last outbreak. Weidentified potential dengue vector species in three northern towns, Pemba, Nampulaand Nacala, and one southern town, Maputo, during the outbreak in April 2014. Amajor dengue vector species, <i>Aedes</i> (<i>Stegomyia</i>) <i>aegypti</i>, wasfound in all these towns. The dominant vector subspecies in the northern townswas <i>Aedes aegypti aegypti</i>, while <i>Ae. aegyptiformosus </i>was dominant in Maputo. Considering the high proportions of <i>Ae. aegypti aegypti</i> and its high vectorcompetence, the findings from this study suggest that <i>Ae. aegypti aegypti</i> was responsible for the outbreakin the northern Mozambique.

A large-scale field trial to evaluate the efficacy of bacillus larvicides for controlling malaria in western Kenya: Study design and methods

Since malaria vaccine development is slow and parasite resistance to anti-malarial drugs is developing rapidly, vector control is still the most practical method for reducing malaria transmission in developing countries. House spraying and treated bed nets have been popular control measures targeting indoor resting mosquitoes; however, chemical insecticides should be treated and managed with great care. In this proposed study, we will evaluate the efficacy of bacterial larvicides combined with environmental management strategies for controlling malaria vectors and transmission in western Kenya. These control methods are less harmful to the environment. The article describes the study design and methods.
