Background Integrated Vector Control (IVC) remains the approach for managing the malaria-causing vector. The study investigated the contribution of Bacillus thuringiensis israelensis (Bti) in the control of malaria by targeting the larvae and also mapped and documented major breeding sites in the Kumasi metropolis, Ghana. Methods Using a hand held...

Following studies on the transmission of Onchocerca volvulus (Leuckart) by Simulium sanctipauli Vajime & Dunbar (Diptera, Simuliidae) in Upper Denkyira District in Ghana in 2001 and 2002 (Kutin et al., Med Vet Ent 18:167-173, 2004), further assessments were carried out in 2006 and 2013/2014 to determine whether transmission parameters had changed s...

Abstract Background: The application of insecticides targeted at vector mosquitoes through Indoor Residual Spraying has been adopted as one of the most effective ways of reducing the burden of malaria. However, key to the success of such a strategy is baseline information about local vector population and their profiles to any of the chemicals appl...

Background There have been recent reports of surge in resistance to insecticides in pocketed areas in Ghana necessitating the need for information about local vector populations and their resistance to the insecticides approved by the World Health Organization (WHO). We therefore studied a population of malaria vectors from Kumasi in the Ashanti Re...

Background Ticks are vectors of pathogens that affect the health of animals and humans. With the constant trade of livestock across borders, there is the risk of new tick species invasion accompanied by the spread of infectious tick‐borne pathogens. Aim This study sought to determine the diversity of tick species within abattoirs and a slaughter s...

The introduction of COVID-19 vaccines in sub-Saharan Africa has been met with mixed feelings. In Ghana, several concerns were raised about the potency and side effects of the COVID-19 vaccine. We investigated the acceptance and risk perception of students on the KNUST campus and the residents of the surrounding communities to assess the risk factor...

Ticks are important disease vectors affecting animal health and causing substantial economic loss, especially in the tropics and subtropics. To examine the tick burden of cattle and associated risk factors for tick infestation, ticks were collected from 388 cattle within five regions in Ghana. Most of the cattle were males (50.3%) and generally old...

Background & objectives Widespread pyrethroid resistance and plastic-feeding behaviour of most malaria vectors across Africa threaten the efficacy of current insecticide-based vector control interventions like Insecticide-Treated Nets (ITNs) and Indoor Residual Spraying (IRS). This study examined the larvicidal activity of Morinda citrifolia agains...

In Ghana, most smallholder maize farmers delay harvesting of their crops in an attempt to achieve optimum moisture content levels necessary for safe storage. Late harvesting may cause a hike in insect attacks and fungal contaminations, leading to alterations in nutrient composition of grains. This study examined the effects of harvest time and stor...

The aim of this study was to determine the effects of harvest time and storage form on population levels of insect pests and their damage on stored maize. Maize was cultivated on a total land area of 19 x 23m2 during the major season (April to August 2020) and minor season (September to December 2020). Maize was harvested at three stages; early har...

Introduction Recent surge of Anopheles resistance to major classes of World Health Organization (WHO)-approved insecticides globally necessitates the need for information about local malaria vector populations. It is believed that insecticide efficacy loss may lead to operational failure of control interventions and an increase in malaria infection...

Background: Praziquantel (PZQ) is the standard treatment for Schistosomiasis in sub-Saharan Africa. However, there is evidence suggesting praziquantel treatment failure in Schistosome infections with associated potential renal impairment. The objective of this study was to determine the effect of three monthly doses of 60 mg/kg/day PZQ on schistos...

Brucellosis remains neglected in many countries despite its public health importance. In developing countries such as Ghana, there remains paucity of data particularly among high-risk populations such as slaughterhouse workers. The aim of this studywas to determine the prevalence of Brucella infection and risk factors for its transmission among peo...

Background Persons with Disabilities (PWDs) are a unique group that are often overlooked in many developing countries due to systemic weaknesses, lack of political commitment and inadequate support from government and non-governmental agencies. The population of these individuals is however steadily on the increase and currently corresponds to 15 %...

Malaria continues to be the leading cause of morbidity and mortality globally. In Ghana control of the vector involves multiple strategies. One of the strategies being adopted is the integrated vector management (IVM) control approach. However, there is evidence of growing resistance by malaria vectors in the country to several classes of insectici...
