Sweet Potato Leaf Spot Diseases and Farmer’s Indigenous Knowledge in Parts of Western Kenya
(International Journal of Research Studies in Agricultural Sciences (IJRSAS), 2021-11)Sweet potato (Ipomoea batatas L.) is a starchy, tuberous root with worldwide consumption. Production of sweet potatoes in Kenya is low due to disease constraints, such as fungal sweet potato leaf spot (SPLS), which is not ... -
The Role of Acid Concentration on Band Gap Shrinkage in Cellulose Nanocrystals Fabricated from Water Hyacinth
(Journal of Material Sciences & Manufacturing Research, 2022-01-05)In this study, the fingerprint of the acid concentration during the hydrolysis process on the optical band gap of cellulose nanocrystals (CNCs) has been systematically studied. The CNCs have been prepared using hydrochloric ... -
Analysis of an Arterial Pulse Using 1D KdV Model
(IRE Journals, 2022-01)In this study we developed a soliton model of an arterial pulse. The Korteweg-de Vries wave equation is our model of interest. It incorporates the aspect of modeling an arterial pulse which can potentially lead to development ... -
Residual Plasmodium falciparum Parasitemia in Kenyan Children After Artemisinin- Combination Therapy Is Associated With Increased Transmission to Mosquitoes and Parasite Recurrence
(The Journal of Infectious Diseases, 2013-08-14)Parasite clearance time after artemisinin-based combination therapy (ACT) may be increasing in Asian and African settings. The association between parasite clearance following ACT and transmissibility is currently unknown. ... -
Malaria Transmission after Artemether-Lumefantrine and Dihydroartemisinin-Piperaquine: A Randomized Trial
(The Journal of Infectious Diseases, 2013-03-06)Artemisinin-based combination therapy (ACT) reduces the potential for malaria transmission compared with non-ACTs. It is unclear whether this effect differs between ACTs. Methods. A total of 298 children (age, 6 months ... -
Crop Damage by Granivorous Birds Despite Protection Efforts by Human Bird Scarers in a Sorghum Field in Western Kenya
(Journal of African Ornithology, 2014-11-14)Cereal crop damage from granivorous birds poses a serious food security problem for subsistence farmers in sub-Saharan Africa. In this region, farmers may rely on human ‘bird scarers’ to limit crop damage. Here we report ... -
Spatial Heterogeneity of Malaria Vectors and Malaria Transmission Risk Estimated Using Odour-Baited Mosquito Traps
(BMC- Malaria Journal, 2014-09-22)Prior to the commencement of a large-scale malaria intervention study on Rusinga Island, western Kenya, intensive baseline surveillance of the mosquito population was performed using odour-baited traps. The survey aimed ... -
Evaluation of Textile Substrates for Dispensing Synthetic Attractants for Malaria Mosquitoes
(BMC- Parasites & Vectors, 2014-08-16)The full-scale impact of odour-baited technology on the surveillance, sampling and control of vectors of infectious diseases is partly limited by the lack of methods for the efficient and sustainable dispensing of attractants. ... -
Field Evaluation of a Push-Pull System to Reduce Malaria Transmission
(Plos One, 2015-04-29)Malaria continues to place a disease burden on millions of people throughout the tropics, especially in sub-Saharan Africa. Although efforts to control mosquito populations and reduce human-vector contact, such as long-lasting ... -
Understanding the Long-Lasting Attraction of Malaria Mosquitoes to Odor Baits
(Plos One, 2015-02-23)The use of odor baits for surveillance and control of malaria mosquitoes requires robust dispensing tools. In this study, the residual activity of a synthetic mosquito attractant blend dispensed from nylon or low density ... -
Innovative Tools and OpenHDS for Health and Demographic Surveillance on Rusinga Island, Kenya
(BMC, 2015-09-01)Health in low and middle income countries is on one hand characterized by a high burden associated with preventable communicable diseases and on the other hand considered to be under-documented due to improper basic health ... -
Development and Optimization of the Suna Trap as A Tool for Mosquito Monitoring and Control.
(BMC- Malaria Journal, 2014-07-08)Monitoring of malaria vector populations provides information about disease transmission risk, as well as measures of the effectiveness of vector control. The Suna trap is introduced and evaluated with regard to its potential ... -
Spatially Variable Risk Factors for Malaria in a Geographically Heterogeneous Landscape, Western Kenya: An Explorative Study
(Malaria Journal, 2016-06-01)Large reductions in malaria transmission and mortality have been achieved over the last decade, and this has mainly been attributed to the scale-up of long-lasting insecticidal bed nets and indoor residual spraying with ... -
Enhancing Attraction of African Malaria Vectors to a Synthetic Odor Blend
(SpringerLink, 2016-06-27)The deployment of odor-baited tools for sampling and controlling malaria vectors is limited by a lack of potent synthetic mosquito attractants. A synthetic mixture of chemical compounds referred to as “the Mbita blend” ... -
The Effect of Mass Mosquito Trapping on Malaria Transmission and Disease Burden (Solarmal): A Stepped-Wedge Cluster-Randomised Trial
(The Lancet, 2016-09)Odour baits can attract host-seeking Anopheles mosquitoes indoors and outdoors. We assessed the effects of mass deployment of odour-baited traps on malaria transmission and disease burden. We installed solar-powered ... -
2-Butanone as a Carbon Dioxide Mimic in Attractant Blends for the Afrotropical Malaria Mosquitoes Anopheles Gambiae and Anopheles Funestus
(Malaria Journal, 2017-08-25)Most odour baits designed to attract host-seeking mosquitoes contain carbon dioxide (CO2), which enhances trap catches, given its role as a mosquito flight activator. However, the use of CO2 is expensive and logistically ... -
Independent and Interactive Effect of Plant and Mammalian Based Odors on The Response of the Malaria Vector, Anopheles Gambiae.
(Science Direct, 2018-05-02)Several studies have shown that odors of plant and animal origin can be developed into lures for use in surveillance of mosquito vectors of infectious diseases. However, the effect of combining plant- and mammalian-derived ... -
Artisanal Fishing Supports Breeding of Malaria Mosquitoes in Western Kenya
(BMC, 2019)Background: Everyday hundreds of people, mainly men, set out to take part in a vibrant artisanal capture fshing (ACF) industry on Lake Victoria. It is not known whether actions of artisanal fshers, in their unrelenting ... -
Use of Semiochemicals for Surveillance and Control of Hematophagous Insects
(Chemoecology, 2020-06-23)Reliance on broad-spectrum insecticides and chemotherapeutic agents to control hematophagous insect vectors, and their related diseases is threatened by increasing insecticide and drug resistance, respectively. Thus, ... -
