Factors determining the use of botanical insect pest control methods by small-holder farmers in the Lake Victoria basin, Kenya

    A farm survey was conducted in three representative administrative districts of the Lake Victoria Basin (LVB), Kenya to document farmers’ indigenous knowledge and the factors that influence the use of botanicals instead of synthetic insecticides in insect pest management. A total of 65 farm households were randomly sampled using stratified sampling procedure. The...

Survey of bacterial pathogens on leaves and seeds of red mangrove (Rhizophora mangle)

  Bacterial pathogens of red mangrove (Rhizophora mangle) were investigated. 50 samples each of leaves and seeds (healthy and diseased) were randomly collected and used for the analysis. Mean bacterial counts obtained were: healthy and diseased leaves; 8.26...

A comparative study on indoor air quality in a low cost and a green design house

A study on Indoor Air Quality (IAQ) is important because people spend most of their time inside houses. IAQ was monitored in two different types of rural houses namely a low cost house and a “green” house built with pyramidal shape of roof in the rural area. Carbon monoxide (CO) and Carbon Dioxide (CO2) concentrations were measured and analysed indoor and outdoor in both the type of houses. A...

Bioremediation of hydrocarbon contaminated-oil field drill-cuttings with bacterial isolates

  The effectiveness of 2 bacterial isolates (Bacillus subtilis and Pseudomonas aeruginosa) in the restoration of oil-field drill-cuttings contaminated with polycyclic aromatic hydrocarbons (PAHs) was studied. A mixture of 4 kg of the drill-cuttings and 0.67 kg of top-soil were charged into triplicate plastic reactors labeled A1 to A3, B1 to B3, C1 to C3 and O1 to O3. These were left quiescent for 7...

Hydrodynamic characterization of the Paleocene aquifer in the coastal sedimentary basin of Togo

  The intense exploitation of shallow aquifers in the coastal basin of Togo provokes a rapid depletion of these reservoirs. The confined paleocene aquifer represents potential reserves that are yet little exploited. This paper presents the hydrodynamic characterization of this aquifer. Piezometric data established from 80 wells fluctuate between 1.17 and 3.42 m; and demonstrate the effect of pumping on...

Seasonal variation in fish abundance and physico-chemical parameters of Lagos lagoon, Nigeria

  A Study was conducted to determine abundance of fish over two seasons (dry and wet) in Lagos lagoon. Fish sampling was carried out in four selected stations. Physico – chemical characteristics of Lagos lagoon and fish distribution was also studied. The results revealed that Cichlids contributed the highest number of fish in the two seasons. Fish species were more evenly distributed in the dry seasons...
