Abstract: Maize is the most widely grown cereal crop worldwide, and is the most important staple crop in sub-Sahara Africa. The spotted stemborer, Chilo partellus (Swinhoe) (Lepidoptera:Crambidae) is considered among the most important pests of maize and the damage it causes may result in yield losses of up to 88%. Previous studies showed that plants damaged by herbivores release huge amounts of volatile compounds, known as herbivore-induced plant volatiles (HIPVs) into the environment, whic...
Abstract: Globally, orange is one of the major fruit crops contributing to nutrition and monetary income. False codling moth (FCM), Thaumatotibia leucotreta, is one of the major constraints of orange production. Before this study, little was known regarding the bioecology of FCM in orange and vegetables in Kenya and Tanzania and the potential use of dry conidia of entomopathogenic fungi for control of T. leucotreta moths has not been tested. There is also no IPM strategy available for FCM in...
Abstract: Tephritid fruit flies are among the most destructive pest species of fruits and vegetables in many regions of the world. Apart from high losses in yield, tephritid fruit fly pests pose great socioeconomic and ecological challenges as well as demand effective measures to curb infestation which can be costly. Among currently used management options are the use of chemical insecticides, behavioral, genetic, cultural and biological approaches. However, no single method or combination o...
Abstract: Information on pesticide residue occurrence in hive products is scanty or lacking yet it is important so as to safeguard human health from effects of pesticides. The aim of the study was to identify and quantify neonicotinoid residues in hive products. The study was undertaken for 6 months between (March-August, 2015) at Kiambu and Nairobi Counties. The objectives of the study were to find out the pesticides used in the cultivation of crops, the frequency of use and the concentrati...
ABSTRACT Plastics are synthetic polymers made by chains of carbon atoms with hydrogen, oxygen, nitrogen, Sulphur built around the carbon chains (Shah et al., 2008). These polymers are involved in every domain of our lives ever since its production began from the year 1950’s, plastics have been produced at an augmented rate to meet day to day demands of the entire world. Accumulation of plastic waste in the environment causes chemical pollution when methods like incineration are used to get ...
This project titled Bioaccumulation of persistent pollutants in Clarias gariepinus gotten from Ogu Creek is based on ecotoxicology and utilized African catfish (Clarias gariepinus) as a model in estimating the bioaccumulation of pollutants in living tissues of organisms in Ogu creek which is a point of poorly treated effluent discharge. The persistent pollutants include Zn, Cr, Cd, Pb, Mn, and Total Petroleum Hydrocarbon (TPH). The concentrations of the heavy metals were determined with Atomi...
The impacts of industrialization on socio-economic development can't be over emphasized, but so are the negative consequences. This paper examines the health and environmental impacts of Dangote Cement Industry on the physical environment of the encompassing settlement of Obajana, Kogi State. this is often with a view to providing sustainable solution to the negative impact of huge scale industries in an emerging economy like Nigeria. The study involved empirical observation and inter...

Surface water quality was accessed at Mbagule-Ipav, Gboko LGA Benue state, Nigeria, a community dominant with agricultural activities. Investigation showed that the community has one stream which serves as the only source of water to the community for domestic and agricultural purposes. This research was to ensure the use of clean and safe drinking water for the public health protection. On this regard, a physicochemical and Microbial analysis of the surface water was carried out for s...
Considerable numbers of outdoor workers worldwide are exposed to solar radiation and this exposure induces various adverse health effects on the workers. This study was conducted to determine the effect of solar radiation on human response during block laying in Ogun State, Nigeria. Two hundred and four masons performing block laying in outdoor environment were investigated between January and December. The meteorological parameters were measured and recorded around the mason which in...
ABSTRACT The land use/land cover of urhonigbe forest reserve between 1987 and 2015 was analyzed to determine the rate and nature of the land use change over time and their possible effect on the forest ecosystem of Urhonigbe Forest. Satellite Remote Sensing and GIS techniques was applied in monitoring Urhonigbe Forest Reserve in Edo State. The land use change and its effect during the time period (1987-2015) were also determined. Onscreen digitization of the study area maps was employed to d...

The Conference with the theme, “ReThinking Engineering and Technology for Environmental Sustainability in the Face of Global Pandemic” took place at a time the world is still re-adjusting to life in the COVID/post-COVID-19 e...
This paper is an overview of criteria needed for the deployment of CCS technology. This to avoid unnecessary leakage in the storage mechanisms. For a CCS to be successful the criteria must be examined and the site is clear for the technology. This paper give an insight into the basic criteria for the site which will be used for for storage of co2
Abstract Climate Change and global warming are problems that result to an increase in indoor temperature especially in the tropical region. The adverse effect of rise in temperature has increased the need for indoor cooling in order to improve comfort for building occupants. Building envelope separates indoor spaces from outdoor spaces and is also capable of improving indoor comfort through appropriate balance of passive and active techniques. The contemporary concern is on how to improve the...
