  2. Temporal effects of biocontrol processes on nutrient dynamics in a shallow lake: Case study of Lake Xini, Okavango Delta in Botswana

    Temporal effects of biocontrol processes on nutrient dynamics in a shallow lake: Case study of Lake Xini, Okavango Delta in Botswana

    Item type: Journal Article • Journal: African Journal of Aquatic Science • Authors: CN Kurugundla --- , Botswana JC Buru --- , Australia
    Little is known about the effects of weeds on nutrient concentration changes in aquatic environments. We examined alterations to nutrient dynamics from the biocontrol process of Salvinia molesta by the weevil Cyrtobagous salviniae in the Lake Xini of Okavango, Botswana...

  3. Seed powder extract of physic nut (<em>Jatropha curcas</em>) as a biopesticide for weevils (<em>Callosobruchus maculatus</em>) in stored cowpea (<em>Vigna unguiculata</em>)

    Seed powder extract of physic nut (Jatropha curcas) as a biopesticide for weevils (Callosobruchus maculatus) in stored cowpea (Vigna unguiculata)

    Item type: Journal Article • Journal: African Journal of Science, Technology, Innovation and Development • Authors: F. O. Ifeanyieze --- University of Nigeria, Nigeria H. I. Ameh --- University of Nigeria, Nigeria T. E. Ejiofor --- University of Nigeria, Nigeria M. E. Ikehi --- University of Nigeria, Nigeria F. M. Onu --- University of Nigeria, Nigeria
    The study explored the effectiveness of physic nut (Jatropha curcas) in the control of cowpea weevils (Callosobruchus maculatus). The repellence, mortality rates and progeny emergence of weevils were observed, as well as germination viability of the treated cowpea seeds. The...
