Efficacy of an insecticide paint against insecticide-susceptible and resistant mosquitoes - Part 1: Laboratory evaluation

2010

Abstract Background The main malaria vector Anopheles gambiae and the urban pest nuisance Culex quinquefasciatus are increasingly resistant to pyrethroids in many African countries. There is a need for new products and strategies. Insecticide paint Inesfly 5A IGR™, containing two organophosphates (OPs), chlorpyrifos and diazinon, and insect growth regulator (IGR), pyriproxyfen, was tested under laboratory conditions for 12 months following WHOPES Phase I procedures. Methods Mosquitoes used were laboratory strains of Cx. quinquefasciatus susceptible and resistant to OPs. The paint was applied at two different doses (1 kg/6 m2 and 1 kg/12 m2) on different commonly used surfaces: porous (cemen…

Vertical transmission of naturally occurring Bunyamwera and insect-specific flavivirus infections in mosquitoes from islands and mainland shores of L…

2018

Background Many arboviruses transmitted by mosquitoes have been implicated as causative agents of both human and animal illnesses in East Africa. Although epidemics of arboviral emerging infectious diseases have risen in frequency in recent years, the extent to which mosquitoes maintain pathogens in circulation during inter-epidemic periods is still poorly understood. This study aimed to investigate whether arboviruses may be maintained by vertical transmission via immature life stages of different mosquito vector species. Methodology We collected immature mosquitoes (egg, larva, pupa) on the shores and islands of Lake Baringo and Lake Victoria in western Kenya and reared them to adults. Mo…

Causes and motives of early marriage in the Gambia and Tanzania : is new legislation enough?

2017

Both The Gambia and Tanzania have high rates of under-18 marriage for girls and both also raised the legal age of marriage for girls to 18 in 2016. This ethnographic study of the urban Muslim poor in Tanzania and The Gambia explores the causes behind and meanings of early marriage in these countries and discusses the likelihood of the recent legislative changes to have effect on actual practice among the poor in the towns and cities of these countries.

Internet abuse by university students: a neglected theme in Africa

2013

The purpose of this paper is to investigate potential Internet abuse by university students, an area lacking research focus in Africa. A case study was conducted at the University of The Gambia (UTG) in 2012. A total of 200 questionnaires were randomly administered to UTG students and 181 valid responses were available for analyses. The result indicates that about 18% of UTG students use the Internet for unspecified activities, demonstrating attributes that could reveal potential Internet abuse. Considering the negative implications of this phenomenon, African researchers cannot afford to neglect this theme. peerReviewed

The Population Genomics of Anopheles gambiae Species Complex: Progress and Prospects

2021

Anopheles gambiae sensu lato is a species complex containing principal malaria vectors such as An. gambiae sensu stricto, An. coluzzii, and An. arabiensis. Numerous studies have shown dynamic species hybridization among member of this complex makes them an ideal model for studying evolution and speciation as well as for applied vector biology. Applying a population genomics approach to the An. gambiae and An. coluzzii species group has led to a number of important and epidemiologically relevant insights including: (1) organization of genomic divergence into “islands of speciation”; (2) competing models of population origin of An. gambiae and An. Coluzzii; (3) description of asymmetric intro…

Evaluation of the efficacy of a new insecticide paint against malaria vectors

2015

La malaria continúa siendo un problema de salud pública global. Se calcula que en el mundo hay 3.300 millones de personas en 97 países y territorios que corren el riesgo de padecer el paludismo, y que para 1.200 millones ese riesgo es elevado (WHO, 2014). El control de la malaria a gran escala está altamente basado en al control del vector, principalmente mediante el uso de mosquiteras tratadas con insecticidas de larga duración (LLINs), y en menor medida, el Rociamiento Residual Intradomiciliario. Todos los tratamientos recomendados de LLINs y la mayoría del Rociamiento Residual Intradomiciliario se basan en el uso de piretroides. La creciente resistencia de los vectores de malaria a los p…

Fostering the relationship between home and school : a case study of a senior secondary school in the Gambia

2011

The study examines the extent to which the relationship between home and school affects students’ academic achievements. A senior secondary school in The Gambia was chosen for this study. The focus of the research was to identify and describe intentionally designed programs and practices that foster the involvement of home in school activities and its important outcomes for the stakeholders (home and school). A qualitative method using semi-structured interviews was used to collect the data from the school principal, four English language teachers and ten parents in order to explore the nature and the degree of support they provide for students. The data was analyzed by the researcher using…
