The bioactivity of the aqueous extracts of the leaf and stem bark of the medicinal plant, Alstonia boonei De Wild (Apocyanaceae), against the pink stalk borer, Sesamia calamistis Hampson (Lepidoptera: Noctuidae) was studied in a laboratory bioassay. The extracts were incorporated into artificial diet at a rate of 0.0% (control), 1.0%, 2.5%, 5.0%, and 10.0%(More)
Yellow fever (YF) is a vector-borne disease affecting humans and non-human primates in tropical areas. In the past, there have been pockets of YF outbreaks in Nigeria that resulted in preventable deaths. Surveillance efforts towards avoiding another outbreak have been put in place with the aim of early detection and control. However, risk indices relating(More)
Miracidia of Fasciola gigantica have a maximum longevity of 9 h. Miracidial survival was found to be age dependent and the instantaneous mortality rate increased exponentially with miracidial age and pesticide treatment. Mortality of the pesticide-treated miracidia differs significantly from that of the control. The LC50 value for Hexadrin was calculated at(More)
Animal African Trypanosomiasis (AAT) is caused by several species of trypanosomes including Trypanosoma congolense, T. vivax, T. godfreyi, T. simiae and T. brucei. Two of the subspecies of T. brucei also cause Human African Trypanosomiasis. Although some of them can be mechanically transmitted by biting flies; these trypanosomes are all transmitted by(More)
The effect of two chemical compounds commonly used in agriculture, Gramoxone (a herbicide) and Hexadrin (an insecticide) on embryonic development and hatching of Fasciola gigantica miracidia were experimentally assessed. These two pesticides were introduced in varying quantities into petri dishes containing unembryonated eggs of the trematode for a period(More)
