Effects of pea aphid secondary endosymbionts on aphid resistance and development of the aphid parasitoid Aphidius ervi: a correlative study
(2010-05)In order to reduce parasite-induced mortality, hosts may be involved in mutualistic interactions in which the partner contributes to resistance against the parasite. The pea aphid, Acyrthosiphon pisum Harris (Hemiptera: ... -

Effects of Zeolite X on Dissipation of Hexazinone from Agricultural Waste Waters in Western Kenya
(2013-10)Dissipation of hexazinone in Zeolite X treated wastewater followed pseudo first-order kinetics giving a calculated half-life of 41 days compared to a half-life of 144 days in untreated wastewater. The herbicide degraded ... -
Evaluating diversity among Kenyan sweet potato genotypes using morphological and SSR markers
(2010)Genetic diversity of 89 sweet potato genotypes was evaluated using morphological and molecular markers. Eighteen aerial and sixteen storage root characters were used in the morphological characterization. Analysis of ... -
Evaluation of an antigen-antibody “combination” enzyme linked immunosorbent assay for diagnosis
(2014-10)Background Development of “combination” assays detecting in parallel, within a single test, Hepatitis C Virus (HCV) antigens and antibodies, not only reduces the window period in HCV-infection but also costs. Reduction ... -

(2014-10)BACKGROUND: Development of “combination” assays detecting in parallel, within a single test, Hepatitis C Virus (HCV) antigens and antibodies, not only reduces the window period in HCV-infection but also costs. Reduction ... -
Evaluation of beverage quality and green bean physical characteristics of selected Arabica coffee genotypes in Kenya
(Academic Journals, 2009-10)Physical characteristics of green coffee bean have been reported to affect beverage quality to some extent. The objective of this study was to assess the beverage quality and green bean physical characteristics of forty ... -
Evaluation of prokaryotic diversity of five hot springs in Eritrea
(BioMed Central, 2017-09)Background: Total community rDNA was used to determine the diversity of bacteria and archaea from water, wet sediment and microbial mats samples of hot springs in the Eastern lowlands of Eritrea. The temperatures of ... -
Expression of metallothionein and tubulin in heavy metal-tolerant Anopheles gambiae sensu stricto (Diptera:Culicidae).
(Elsevier, 2010)Anopheles mosquitoes have been shown to adapt to heavy metals in their natural habitats. In this study we explored the possibility of using Anopheles gambiae sensu stricto as bioreporters for environmental heavy metal ... -
Field Abundance Patterns and Odor-Mediated Host Choice by Clover Seed Weevils, Apion fulvipes and Apion trifolii (Coleoptera: Apionidae)
(2015-02)The clover seed weevils Apion fulvipes Geoffroy, 1785 and Apion trifolii L., 1768 (Coleoptera: Apionidae) cause major losses to seed production of white clover (Trifolium repens L.) and red clover (Trifolium pratense ... -
