Surface runoff and soil erosion from and as influenced by different soil organic carbon levels under simulated rainfall conditions.

Soil erosion poses a challenge to the environment and the sustainable use of natural resources, particularly in relation to agricultural production. The study aimed to assess the influence of different soil organic carbon (SOC) levels on runoff and soil erosion under varying levels of rainfall intensity. The study was conducted in pre-selected farmers' fields representing low, moderate and adequate SOC levels in and .

The Entomopathogenic Fungi and for Management of the Melon Fly : Pathogenicity, Horizontal Transmission, and Compatability with Cuelure.

In the laboratory, the pathogenicity of thirteen isolates of (Metschnikoff) Sorokin and two isolates of (Balsamo) Vuillemin against the melon fly (Coquillett) were assessed by exposing adults to 0.3 g of dry conidia (~3 × 10 conidia) of each isolate for 5 min and monitoring mortality for up to 5 days. Compatibility with a male pheromone, cuelure, (4-(p-acetoxyphenyl)-2-butanone), was determined by testing conidial germination and germ tube growth of the most promising isolate, ICIPE 69, in the presence of cuelure at different temperatures.

Characterization of the Volatile Components of Essential Oils of Selected Plants in Kenya.

Essential oils are secondary metabolites that plants produce for protection from pests and predators, attraction of pollinators, and seed dispersal. The oils are made up of a mixture of compounds that give a characteristic flavour and odour. Currently, essential oils are receiving great attention in research for their phytochemical and antimicrobial activities.

Morphological and Molecular Characterization of Toxigenic from Groundnut Kernels in Kenya.

Pathogenesis of on important agricultural products is a key concern on human health due to the synthesis and secretion of the hazardous secondary metabolite, aflatoxin. This study identified and further characterized aflatoxigenic from groundnuts sampled from sundry shops in Kenya using integrated morphological and molecular approaches. The groundnuts were plated on potato dextrose agar for isolation and morphological observation of based on macroscopic and microscopic features.

Performance of Three Isolates of and Their Virulence against under Different Temperature Regimes, with Global Extrapolation of Their Efficiency.

The performance of entomopathogenic fungi in pest control is usually affected by both biotic and abiotic factors. This study aimed to determine the effects of various temperatures (15, 20, 25 and 30 °C) on conidial germination, mycelial growth and conidial density and virulence to the melon fly of three selected isolates of The three isolates, ICIPE 18, ICIPE 30 and ICIPE 69, had previously been selected in laboratory bioassays. Percentage mortality by the three isolates ranged between 16.

Trypanosoma Infection Rates in Glossina Species in Mtito Andei Division, Makueni County, Kenya.

African Animal Trypanosomiasis (AAT) transmitted cyclically by tsetse fly (Glossina spp.) is a major obstacle to livestock production in the tropical parts of Africa. The objective of this study was to determine the infection rates of trypanosomes in Glossina species in Mtito Andei Division, Makueni County, Kenya.
