Introduction
I am a Senior lecturer at the Department of Conservation Biology and Entomology of the School of Biological Sciences, College of Agriculture and Natural Sciences, University of Cape Coast. I have been involved in assessment on Ghana’s insect fauna, bee keeping training, consultancy and monitoring since 2005. Biodiversity and insect pollinator –food crop assessment has also been key in my research career. Currently, I have published in local and international journals on Insect Biosystematics. I've been a student counselor since 2010 and now an Academic Advisor. Current research interests in the applications of geometric morphometrics and biophotonics in insects, especially bees & their products' classification. Other research includes chemotaxonomy of insects and their ecological roles.

Article
Full-text available
Bed bugs, Cimex lectularius (L.) (Hemiptera: Cimicidae) and Cimex hemipterus (F.), have become established worldwide in recent years largely due to the development of insecticide resistance. However, limited attention has been given to ongoing morphological and macroevolutionary changes within the species and their populations, which could have imp...
Article
Full-text available
Invasive alien species (IAS) continue to shape the global landscape through their effects on biological diversity and agricultural productivity. The effects are particularly pronounced in Sub-Saharan Africa, which has seen the arrival of many IAS in recent years. This has been attributed to porous borders, weak cross border biosecurity, and inadequ...

Honey is commonly used as a food sweetener in Ghana and it is one of the most important food products with enormous nutritive benefits. In recent times, the increasing concern about sugar related diseases such as diabetes has led to increased consumption of honey in Ghana. This study assessed the physico-chemical properties and microbiological qual...

The black soldier fly is considered an important insect due to its ability to convert organic wast into high quality organic fertilizer. Studies have shown that food quality at the larvae stage contributes greatly to their development. In this study, we applied geometric morphometric measurements to access the variations in the black soldier fly fe...
Article
Full-text available
This study reports the first baseline information on tropical bed bug, Cimex hemipterus (F.) (Hemiptera: Cimicidae), infestations in Ghana. The purpose of this study was to assess bed bug infestation levels, and the efficacy of locally available insecticides and long-lasting insecticidal nets (LLINs) in controlling field bed bugs populations in the...
Article
Full-text available
Variability in ambient climate and weather conditions greatly influences the survival and distribution of many important flora or faunal species, especially bee pollinating species. In this study, the impact of variation in two air pollutants (Carbon monoxide in parts per million (CO_PPM) and Ozone in parts per million (O3_PPM), as well as humidity...
Article
Full-text available
This research was carried out to assess the behavioural variability of Apis mellifera adansonii in three ecological zones in Ghana. Other specific objectives include; evaluation of aggression and entrance guarding behavioural patterns, assessment of the effect of climatic condition on honey bees’ behaviour. Entrance guarding behaviour was assessed...

This research was carried out to assess the behavioral variability of Subspecies Apis mellifera adansonii in three ecological zones in Ghana. Other specific objectives include; evaluation of aggression and entrance guarding behavioral patterns, assessment of the effect of climatic condition on honey bees’ behavior. Entrance guarding behavior was as...
Article
Full-text available
The development of computational morphometric identification systems in recent times has invariably made it possible for easy segregation of closely related species and subspecies using only wing features. In this research, assessment on possible variabilities within Apis mellifera adansonii in three ecological zones in Ghana were carried out based...

Article
Full-text available
The Afrotropical bee genus Anthidiellum is revised. This group of solitary bees comprises three subgenera within the Afrotropical region. Two of these subgenera are endemic species, while the third subgenus occurs in both Orient as well. Seventeen extant species are recognized, two of which are described as new, and four species have been left in a...

Wild and managed pollinators including bees contribute to food security, biodiversity conservation and ecosystem stability. Across different landscapes, plant abundance and diversity change. Bee distributions may vary spatially in relation to differences in phenology. This study was carried out to identify the bee fauna in the Forest-Savannah Trans...
Article
Full-text available
A total of 21 okra (Abelmoschus escuentus L. Moench) genotypes were screened for their reactions against okra mosaic disease (OMD) and flea beetles (Podagrica species) infestations in field trials which were conducted from May to October, 2015 (wet season) and November 2015 to March 2016 (dry season), in order to identify sources of resistance and...
Article

Many species of insects are known to be associated with carrion and impacts greatly on the decay rate as well as provide useful data on the mode and time taken for death of that organism. In this study, the diversity of insect associated with the different stages of decomposition, the effect of insects’ presence on the decay rates due to difference...
Article
Full-text available
Even though several ecological studies on various fauna studies have been carried out in the Kakum National Park, record on the bee fauna is lacking in spite of the fact that bees are one of the most economically important insects. Bees constitute 60%-70% of all insect pollinators. This research was set out to assess the bee fauna within three land...
Article
Full-text available
Geometric morphometric techniques were used to assess possible ecotypes within four species of African stingless bees from three different ecological zones in Ghana. Canonical Variate Analyses, Discriminant Analyses, Principal Component Analyses among other techniques evaluated shape variations of eight homologous landmarks on right forewings and e...
Article
Full-text available
Despite the important role rainforest biodiversity play globally in our survival, limited knowledge of its floral and faunal compositions as well as influences of key environmental parameters seem to be known by the general public especially Children. This study therefore focused on assessing the knowledge of school children within four different a...
Article
Full-text available
Insect pollinators provide a critical ecosystem service by pollinating many wild flowers and crops. It is therefore essential to be able to effectively survey and monitor pollinator communities across a range of habitats, and in particular, sample the often stratified parts of the habitats where insects are found. To date, a wide array of sampling...
Article
Full-text available
The phylogenetic relationships among members of long tongue bee tribe Anthidiini (Megachilidae: Megachilinae) were investigated at the Department of Entomology and Wildlife, University of Cape Coast (Ghana) and the Agricultural Research Council, Pretoria (South Af-rica) from July, 2006 to May, 2007. Ten museums located in three continents loaned th...

Project
Basic practical laboratory sessions are periodically organized for students in Junior High Schools to encourage and motivate them especially the girls to pursue science related subjects such as Biology, Chemistry, Physics, Mathematics and Information technology.These practicals based on the Ghana Education Service Syllabus and are aimed at helping students understand the topics by treating them in an exciting way.
Project
Insect perception of colour is crucial in navigating through its environment as well as intra- and inter- specific communications. Specific projects are designed to assess pigmentary and structural colors in the compound eyes of insects of agriculture importance
