insects wellknown for their public importance, since they act as vector for many tropical and subtropical disease such as dengue fever, yellow fever, chikungunya, malaria, filariasis and encephalitis of different types including, Japanese encephalitis1. Larviciding is a successful way of reducing mosquito densities in their breeding places before they emerge into adults. Larviciding largely dep...

Background: With the rapid expansion of insecticide resistance limiting effectiveness insecticide-based vector control interventions, integrated strategies associating larviciding could be appropriate to improve current efforts. The present experimental study assesses laboratory and field efficacy larvicide VectoMax®G on Anopheline Culicine larval stages in Yaoundé. Methods: effect VectoMax®G, ...

INTRODUCTION The use of remote sensing has found its way into the field of epidemiology within the last decades. With the increased sensor resolution of recent and future satellites new possibilities emerge for high resolution risk modeling and risk mapping. METHODS A SPOT 5 satellite image, taken during the rainy season 2009 was used for calculating indices by combining the image's spectral ...

Ultra-low volume (ULV) application of insecticide is widely recognized to be effective against adult mosquitoes. Hobbs (1976) reported that ULV applications of synergized pyrethrins applied with ground equipment reduced the natural population of ArnpheLes albimanus Wied.. during a heavy malaria transmission season. However, a single ULV application cannot be expected to provide lasting effectiv...

Malaria not only remains a leading cause of morbidity and mortality, but it also impedes socioeconomic development, particularly in sub-Saharan Africa. Rapid and unprecedented urbanization, going hand-in-hand with often declining economies, might have profound implications for the epidemiology and control of malaria, as the relative disease burden increases among urban dwellers. Reviewing the l...

This review of research on ultralow-volume (ULV) aerial sprays for mosquito control is a component of an Aerial SPray EXpert system (ASPEX). Topics include application volume, adulticiding, larviciding, droplet size, and meteorology. The review discusses the efficacy of ULV aerial sprays against many important pest and vector species of mosquitoes in a wide range of locations and habitats in th...

BACKGROUND Malaria control is based on early treatment of cases and on vector control. The current measures for malaria vector control in Africa are mainly based on long-lasting insecticide treated nets (LLINs) and to a much smaller extent on indoor residual spraying (IRS). A third pillar in the fight against the malaria vector, larval source management (LSM), has virtually not been used in Afr...

BACKGROUND & OBJECTIVES The ecology and distribution of various mosquito species is important in the determination of mosquito vector abundance and associated diseases prevalence. The distribution of various mosquito genera in natural and artificial habitats and their relative species abundance was studied between August 2002 and July 2003 in three foci (Uromi, Ekpoma and Auchi) comprising the ...
