Population genetics of Anopheles funestus, the African malaria vector, Kenya

Abstract: Background: Anopheles funestus is among the major malaria vectors in Kenya and sub-Saharan Africa and has been recently implicated in persistent malaria ransmission. However, its ecology and genetic diversity remain poorly understood in Kenya.Methods: Using 16 microsatellite loci, we examined the genetic structure of An. funestus sampled from 11 locations (n = 426 individuals) across a wide geographical range in Kenya spanning coastal, western and Rift Valley areas. Results: Kenyan...

Abundance of immature Anopheles and culicines (Diptera: Culicidae) in different water body types in the urban environment of Malindi, Kenya

Abstract: In this study we 1) describe the abundance of Anopheles and culicine immatures in different water body types in urban Malindi, Kenya, 2) compare Anopheles immature density in relation to culicine immature density, and 3) identify characteristics that influence the likelihood of water bodies being co-colonized by Anopheles and culicines. Entomological and environmental cross-sectional surveys conducted in 2001 and 2002 were used in the analysis. A total of 889 Anopheles and 7,217 cu...

The Attentive Spider: Search-Image Use by a Mosquito-Eating Predator

Abstract: Evarcha culicivora, a jumping spider from East Africa, feeds indirectly on vertebrate blood by choosing blood-carrying female mosquitoes as prey.It also has an unusually complex mate-choice system. Here, we show that both sexes of E. culicivora can use mate-finding search images and also use prey-finding search images. In experiments, individuals were primed by seeing blood-carrying mosquitoes, primed by seeing potential mates or not primed (control: saw neither). They were then in...

Wide-area invasive species propagation mapping is possible using phenometric trends.

Abstract: Invasive plant species in eastern Africa severely impede rangeland and cropland productivity with dire consequences for livelihoods of agro-pastoralist communities. We produced the first occurrence and spread map of invasive plant species (Prosopis: Prosopis juliflora and Parthenium: Parthenium hysterophorus) for western Somaliland (a region of eastern Africa) using vegetation productivity and phenology trends from 250 m MODIS (Moderate Resolution Imaging Spectroradiometer) EVI (En...

Potential Application of Variable Surface Glycoproteins in Diagnosis of Trypanosoma brucei rhodesiense

Abstract: Sleeping sickness, also known as human African trypanosomiasis (HAT), is a neglected tropical disease caused by two subspecies of Trypanosoma brucei namely T. b. gambiense and T. b. rhodesiense. Trypanosoma b. gambiense causes chronic form of HAT (Gambian HAT) in West and Central Africa while T. b. rhodesiense is responsible for the acute form (Rhodesian HAT) in East and Southern Africa. In both cases, the disease evolves through clinically distinct stages namely early/stage 1 and ...

Properties and performance testing of biodiesel from a mixture of jatropha curcas and croton megalocarpus blends

Abstract: The main objective of this project was to study biodiesel production from two local nonedible plant feedstocks namely Jatropha curcas and Croton megalocarpus. The oil from the above plant seeds were mechanically extracted using a screw pressing machine and the oil yield determined. Preliminary test were done on the neat oil to ascertain their quality, these included; viscosity, density, acid value, iodine and calorific value. The oils were then converted into biodiesel through tran...

Education allows a person t...

Terrorism: A Threat to Security and Human Existence

Terrorism attracted a lot of attention in recent year. Many theories have been  developed by scholars to explain terrorism, its causes, while people resort to extreme violence to make their point. This paper examines some selected theories that could help us gain insight into terrorism and various activities associated with it. One of the major recommendation made by this paper is that terrorism  as a global issue require  increased global attention. There must be concerted effort from bo...

Community Security Self-Help Initiative: A Panacea for Food Sustainability and Grassroot Development in Nigeria

Abstract The research study examines the impact of community security self-help initiative and food security for grassroot development sustainability. Community self-help initiative is not a novel enterprise in communities in Nigeria as evidence abounds of how communities magnificently organized themselves in constructing roads, building bridges, schools, farmland assistance and neighbourhood watchdog to each other. The population of study is 351,865 from residence of Ikole, Efon and Emure lo...

Developing and Validating of Predictive Model for Radiofrequency Radiation Emission Within the Vicinity of Fm Stations in Ghana.

ABSTRACT  The rapid growing number of FM stations with their corresponding antennas have led to an increase in the concern of the potential health risks that may arise as a result of exposure to RF radiations. The main objective of this research was to develop and validate a predictive model with real time measured data for FM antennas in Ghana. Theoretical and experimental assessment of radiofrequency emission due to FM antennas has been analysed. The maximum and minimum electric field spat...
