Abstract: Ticks of the genus Rhipicephalus are important parasites of livestock in the world. Rhipicephalus ticks cause huge economic losses to cattle and have a great capacity to develop resistance to chemical acaricides. There is the need therefore to develop alternative strategies that could complement the existing control methods of this ectoparasite. Entomopathogenic fungi are being considered as a promising option for the control of ticks on-host and off-host. The aim of this study was...
Abstract Forensic Mycology is the application of Mycology for producing evidence in terms of criminal investigation and their further evaluation in the court of law. The problem with relative neglect of Mycology in Forensic science is currently leading to insufficient knowledge, in order to support the needs for fungal expertise in areas of criminal investigation. Mucor hiemalis and Penicillium griseofulvum had been used to determine the minimum interval since death, Coprinus comatus, Hebelom...
ABSTRACT The relationship between five randomly selected isolates of Aspergillus niger from naturally infected bulbs of shallot and two shallot cultivars (Allium ascalonicum L.) was investigated. The two cultivars were “Pale-brown” and “Pink”- named for the colours of their scale leaves. A. niger causes bulb rot of shallots which have important uses in food and traditional medicine in Ghana The relationship showed by the cultivars were similar in some aspects and different in many oth...
ABSTRACT Magnetically recoverable Pd/Fe3O4-catalyzed Hiyama cross-coupling reactions of 6-Bromo-5H-benzo[a]phenothiazin-5-one, 6-Bromo-5H-naphtho[2,1-b]pyrido[2,3-e][1,4]oxazin-5-one and 11-Amino-6-bromo-9-thio-5H-naphtho[2,1-b]pyrimido[5,4-e][1,4]oxazin-5-one (as intermediates) with 2-(Dimethylsilyl)pyridine and Dimethyl(2-thienyl)silanol were investigated. The intermediates were prepared by the reactions of 2-Aminothiophenol, 2-Aminopyridin-3-ol and 4,5-Diamino-6-hydroxylpyrimidin-2-t...
ABSTRACT Climate change coping strategies play a major role in curbing the effects of climatic shocks especially amongst communities living in Arid and Semi-Arid Lands (ASALS. The study revealed that there are various coping mechanisms applied by smallholder farmers in Kaloleni Sub County. These include marrying off daughters in order to get money for food purchase, stealing food from farm, water vending getting women to work outside home against traditions among others. Preferred coping met...
ABSTRACT Finger millet (Eleusinecoracana (L.) Gaertn) is one of the most important crops among the small millets. In Kenya yields are generally low, because of blast caused by the fungus Pyricularia grisea. Low finger-millet production accelerates incidences of malnutrition. Management has been challenging with cultural approach showing minimal success. Comparatively the use of actinomycetes species as a bio-control agent in management of rice blast caused by a similar pathogen, has shown so...
ABSTRACT Oyster mushrooms (Pleurotus species) have been an important food item in both developed and developing countries serving an invaluable resource for nutrition, health and disease prevention. Although several agricultural wastes lignocellulose have been used for cultivation of oyster mushrooms worldwide and in Ghana, the most utilized is the wawa (Triplochiton scleroxylon) sawdust and its amendments for the cultivation of Pleurotus ostreatus in Ghana. However, a longer period of 28 da...
ABSTRACT In the recent time, the use of low cost biosorbents like bacteria, fungi, algae and some agricultural by-products have been investigated for their biosorption capacities. In this work, the biosorptions of three heavy metals (zinc, copper and manganese) from aqueous wastewater solution by five micro-organisms (Bacillus circulans, Pseudomonas aeruginosa, Staphylococcus xylosus, Streptomyces rimosus and Saccharomyces sp.(Yeast) were investigated using a combined flow and batch process...
Abstract: Pachnoda interrupta (Olivier) (Coleoptera: Scarabaeidae) is a damaging pest of sorghum,other cereals and horticultural crops such as maize, wheat, barley, bananas, guava etc. in Africa which at times results in complete crop losses. Current control strategies heavily rely on chemical pesticides. Controlling adult beetles through application of insecticides,in addition to being detrimental to the environment and the ecology, does not provide long lasting control.Thus, efficient biol...
Abstract: Vetiver grass (Chrysopogon zizanioides;CZ) is a well-known grass that can both remediate various heavy metals in soil as well as producing essential oil that is commonly used in premier perfumery, food and pharmaceutical industries. Due to this versatility property, this study was aimed at extracting essential oil from Chrysopogon zizanioides roots cultivated in SelibePhikwe mine tailings and study the quality and quantity (chemical composition and yield) of the Chrysopogon ziza...

DERMATOPHYTE are unique of fungi that effect the Keratinous tissues of lower animals and human Dermatophytoses is the medical term for fungal infection of the superficial layer of the skin, nail, hair and scalp. The prevalence study Dermatophytoses in Wuntin Dada Primary School Bauchi is to determine the prevalence of the diseases, the different clinical types and actual species responsible for the infections. Out of 950 pupils examined, 105 children were found to be with suspected Dermat...
ABSTRACT Endophytic microorganisms have proven to be potential sources of antimicrobials against recalcitrant pathogens. Extracts of an endophytic fungus, Emericella nidulans exhibited antibacterial activity against selected pathogens. Emericella nidulans was cultivated in broth and fermented at 28 ± 2°C for 7days and 21 days to obtain bioactive components. Solvents extraction of bioactive compounds from Emericella nidulans in the order of their polarity – n-Hexane, et...
ABSTRACT Maize production in Ghana between 1984 and 1990 exceeded 500,000 metric tonnes per year except in 1985 where there was a shortfall to 395,000 metric tonnes. The unfavourable years of drought between 1981-1983 were attended by a sharp decline in maize production ( 140,000-333,200 metric tonnes ). The bulk of the national maize production was contributed by Ashanti, Brong-Ahafo, Eastern and Northern Regions. Maize husk available after removing cobs was commensurate with the total maize...
EXTENDED ABSTRACT Rice leaf blast is a rice disease caused by fungus Pyricularia oryzae Cavara. The disease is widely spread in all rice ecological systems in Zanzibar viz; rainfed upland, rainfed lowland and irrigated. In Zanzibar rice is a staple food crop that serves 3.1 millions people but the crop is highly infected with rice leaf blast disease a major producton constraint. A comprehensive survey was conducted in six districts of Zanzibar islands covering three districts in Unguja viz: ...
