(Journal of Nematode Morphology and Systematics, 2005)Zeldia spannata sp. n. is described from the Mojave Desert, California. The new species shares with congeners a single guard process in each primary axil and asymmetrical triangular-shaped lips; it differs from them by the ... -
The International Journal for Microbiologists and Biotechnologists working on Issues Relevant to the Tropics
(Journal of Tropical Microbiology and Biotechnology, 2007)Aggressiveness of fifteen isolates of Phaeoisariopsis griseola and variations in angular leaf spot symptom development in common bean were studied. The isolates were selected based on their virulence and genetic differences ... -
Food Security in Africa: The Challenges of Researchers in the 21st Century
(Springerlink, 2007)Food production in most of Sub-Saharan Africa (SSA) has not kept pace with the population increase over the past three decades. In many countries, food security remains a serious problem. It contributes both to high rates ... -
Impact of an exotic parasitoid on Plutella xylostella (Lepidoptera: Plutellidae) population dynamics, damage and indigenous natural enemies in Kenya
(Cambridge University Press, 2007)Diadegma semiclausum (Helle´n) (Hymenoptera: lchneumonidae), an exotic diamondback moth parasitoid, was released in two pilot areas (Werugha in Coast Region and Tharuni in Central Province) in Kenya. Fifteen month before ... -
Intensive Subsistence Agriculture: Impacts, Challenges and Possible Interventions. Dynamic Soil, Dynamic Plant
(2007)Invited Mini-Review: Despite comprising of 10-80% of total phosphorus (P) in soil solution, little is known of the composition, transformations and loss of dissolved organic P (DOP). Once dissolved in solution, organic ... -
Improving food production using ‘best bet’ soil fertility technologies in the Central highlands of Kenya
(Springer Netherlands, 2007)Declining crop productivity is a major challenge facing smallholder farmers in central highlands of Kenya. This decline is caused by continuous cultivation of soils without adequate addition of external inputs in form of ... -
Banana Xanthomonas wilt: a review of the disease, management strategies and future research directions
(African Journal of Biotechnology, 2007-03)Banana production in Eastern Africa is threatened by the presence of a new devastating bacterial disease caused by Xanthomonas vasicola pv. musacearum (formerly Xanthomonas campestris pv. musacearum). The disease has ... -
Transfer and Development of Pasteuria Penetrans.
(The Society of Nematologists, 2007-03)Pasteuria penetrans isolate P-20 has been attributed as the cause of soil suppressiveness to peanut root-knot nematode in Florida. In this study, P. penetrans was transferred from a suppressive site to a new site and ... -
Can low release numbers lead to establishment and spread of an exotic parasitoid: The case of the diamondback moth parasitoid, Diadegma semiclausum (Hellén), in East Africa
(Science Direct, 2008-06)From 2001 onwards, Diadegma semiclausum, an exotic parasitoid of the diamondback moth, was introduced and released in Kenya, Tanzania and Uganda. Contrary to common practice where thousands of parasitoids are released, we ... -
Overcoming Seed Dormancy in Cleome gynandra L. to Improve Germination
(Association of Official Seed Analysts, 2009)Cleome gynandra L. is a traditional semi-domesticated leafy vegetable grown in East Africa. It belongs to the family Cleomaceae. Farmers save seed from each harvest for planting in the next season. C. gynandra seeds fail ... -
