Background
The study assessed the risk of transmission of Aedes-borne arboviruses in a community at Cape Coast during the Covid-19 restriction period in 2020 based on entomological indices. The spatial distribution of insecticide resistance was also assessed in Ae. aegypti population from Cape Coast.
Methods
Three larval indices were calculated fr...
Rapid urbanization and its associated pollution can affect water quality in mosquito breeding habitats and, as a result, the ecology and control of mosquito vectors. To understand the effects of pollution on mosquito vectors, an accurate assessment of water quality in breeding habitats is needed. Presently, water quality assessment of mosquito bree...
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...
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...
Nuisance from Culex mosquitoes in Ghana has a serious negative impact on the standard of living in many urban communities. In addition, a perceived lack of efficacy of long lasting insecticide treated nets (LLINs) against nuisance mosquitoes contributes to their discontinued use. This again compromises malaria control, even if Anopheles species the...
Background
Besides its role as a pathogen vector, Culex species also indirectly promotes the transmission of malaria if the use of bed nets or indoor residual spraying is discontinued due to a lack of insecticide efficacy against it. A recent survey revealed widespread occurrence of pyrethroid resistance among urban populations of this mosquito in...
To determine resistance status of Culex species to different class of insecticides and assess the major anti-mosquito strategies employed by urban households and their possible effects on malaria acquisition.
Structured questionnaires were randomly administered to obtain information on demographic characteristics, measures that people use to preven...
Insecticides play a major role in controlling the spread of malaria. However, this means of protection is losing its efficacy due to the development of resistance to commonly used insecticides. Pyrethroids are often used in vector control projects due to lower human toxicity, high insecticidal potency and rapid knockdown (KD) effects. Anopheles gam...
The study was carried out to characterize potential larval habitats in the city of Sekondi with the aim of assessing the relative importance of anthropogenic and natural water bodies as larval habitats. Insecticide-resistance status of Anopheles gambiae senso lato in the southwestern part of the coastal savannah zone in Ghana was also assessed agai...
Control programs using conventional insecticides to target anthropogenic mosquito habitats are very expensive because these habitats are widespread, particularly in cities of most African countries. Additionally, there are serious environmental concerns regarding large-scale application of most conventional insecticides. Clearly there is a need for...
As a result of different levels of pollination efficiency of pollinators, knowledge on appropriate pollinators of a plant has become important, especially in the management and conservation of both the pollinators and the plants. In this study, the pollination efficiency of Apis mellifera and Xylocopa olivacea, important pollinators of Luffa aegypt...
Since 2001, there has been a tremendous increase in number of households protected by ITN and IRS in Ghana. However, there has not been evidence of a reduction in malaria cases as expected and reported deaths have rather increased since 2007. As a result, this study was undertaken to get a better understanding of perceptions of malaria, knowledge o...
Luffa aegyptiaca (Cucurbitales: Cucurbitaceae) is a plant of economic importance in Ghana and in other parts of the world, especially in tropical and subtropical regions. Cultivation of the plant in Ghana has reduced over the last two decades, so it now mostly grows in the wild. A survey was conducted in coastal Ghana to provide baseline informatio...
In an attempt to find out if simulated teaching-learning materials could effectively fill in the gap for expensively imported science teaching-learning resources, models for teaching plant and animal cells and the solar system were made and tested. The results showed that between 13.33 -50 % of the students obtained distinction when the models were...
Local or inexpensive materials were used to develop models for teaching chromatography. The models were tried in two Junior Secondary Schools to find out if they could enhance the understanding of the topics. The results showed that using chalk stick, yam and cassava chips as stationary phase and water as mobile phase in separating the components o...
