The monotypic genus Bulborrhizina belongs to Bulbothrix sensu lato (Parmeliaceae, Ascomycota)
(The American Bryological and Lichenological Society, Inc. - The Bryologist, 2015)
The phylogenetic position of the monotypic genus Bulborrhizina is studied using molecular data from three loci (mtSSU, nuLSU and ITS) aligned with sequences from 95 other samples of parmelioid lichens. Bulborrhizina africana ...
The economics and gender factor in soya bean production and profitability in Kenya: a case of smallholder farms in Western Kenya
(Int. J. Agricultural Resources, Governance and Ecology, 2017)
Soya-bean is among world’s major crops, cultivated for its high oil, proteins content and its ability in soil-fertility amendments. The study assessed the determinants, constraints and profitability/gross-margins of soya-bean ...
Catalytic degradation of methylene blue by iron nanoparticles synthesized using Galinsoga parvifora, Conyza bonariensis and Bidens pilosa leaf extracts
(Springer Nature Switzerland, 2019-09)
Green synthesized metallic nanoparticles are environmentally friendly, bio-compatible, and highly stable. The aim of this
study was to synthesize iron nanoparticles (FeNPs) from FeCl3 solution using aqueous leaf extracts ...
Phytofabrication of Iron Nanoparticles and their Catalytic Activity
(Springer Nature Switzerland AG 2019, 2019-06-20)
Metallic nanoparticles that have photocatalytic activity can be synthesized using aqueous plant extracts. The aim of
this study was to synthesize iron nanoparticles using Lantana trifolia extracts and to evaluate their ...
Liriomyza Leafminer (Diptera: Agromyzidae) Parasitoid Complex in Different Agroecological Zones, Seasons, and Host Plants in Kenya
(Environmental Entomology, 2015)
Liriomyza leafminers (Diptera: Agromyzidae) are severe pests of vegetables and ornamentals worldwide. Previous studies revealed low leafminer parasitism across different agroecological zones in Kenya. The present paper ...

(Hindawi Publishing Corporation, 2016-02-17)
Background. School age children are at high risk of soil-transmitted helminth (STH) worldwide. In Kenya, STH infections in children remain high despite the periodic administration of anthelmintic drugs. Our study assessed ...
Bioecology of thrips in French bean growing ecosystem in Kenya
(2012-10-31)
Studies on the bioecology ofthrips on French beans were carried out at Machakos, Kaguru and JKUAT. The general objectives of this study were twofold, namely to study the biology and population dynamics of thrips on French ...
Interaction between Phaedrotomascabriventris Nixon and Opiusdissitus Muesebeck (Hymenoptera: Braconidae) : endoparasitoids of Liriomyza leafminer
(Sabinet African Journals, 2015-03-01)
The exotic parasitoid, Phaedrotoma scabriventris Nixon, was imported from Peru for the biological control of invasive Liriomyza species in vegetable and ornamental crops in Kenya where Opius dissitus Muesebeck is the most ...
Open relationships in the castles of clay: high diversity and low host specificity of Termitomyces fungi associated with fungus-growing termites in Africa
(International Union for the Study of Social Insects (IUSSI), 2010-08)
In the African and Asian tropics, termites of the subfamily Macrotermitinae play a major role in the decomposition of dead plant material. Their ecological success lies in the obligate mutualism of the termites with fungi ...
Host plant resistance among tomato accessions to the spider mite Tetranychusevansi in Kenya
(Springer, 2011-04-11)
The spider mite Tetranychus evansi has a broad range of host plants. Control of T. evansi has been a big challenge to tomato farmers due to its fast rate of reproduction, development of resistance to chemical pesticides ...
