Pathogenicity of Beauveria bassiana, Metarhizium anisopliae and Serratia marcescens to the banana weevil Cosmopolites sordidus
(Uniiversity of Nairobi., 1993)
Two exotic fungal isolates, one of Beauveria bassiana (268–86) and another of Metarhizium anisopliae (100–82), three local isolates of B. bassiana (isolates I, II, III) and one of the entomogenous bacteria Serratia marcescens, ...
Prospects for biological control of livestock ticks, Rhipicephalus appendiculatus and Amblyomma variegatum, using the entomogenous fungi Beauveria bassiana and Metarhizium anisopliae
(University of Nairobi., 1996-01)
Both Beauveria bassiana and Metarhizium anisopliae induced approximately 30% mortalities in adult Rhipicephalus appendiculatus feeding on rabbits while M. anisopliae induced a mortality of 37% in adult Amblyomma variegatum. ...
Mortality and pathology in tsetse flies (Glossina spp.) treated with Neem extracts
(University of Nairobi., 1996)
Lectins in the brown ear tick, Rhipicephalus appendiculatus: detection and partial characterization
(University of Nairobi., 1998)
Lectins (agglutinins) were detected and isolated from the hemolymph and gut of Rhipicephalus appendiculatus, the vector of Theileria parva, using various vertebrate red blood cells (RBC). Although the hemolymph lectin ...
Natural and experimental infection of Rhipicephalus appendiculatus with pathogens and their potential for control of ticks
(University of Nairobi., 1995)
Achieving sustainable food production in Africa: Roles of pesticides and biological control agents in integrated pest management
(University of Nairobi., 1994-04)
Food production in Africa is declining, while her population is increasing rapidly. Some factors responsible for low food productivity are mentioned; special attention is given to the problem of agricultural pests. The ...
Microorganisms associated with tsetse in nature: Preliminary results on isolation, identification and pathogenicity
(University of Nairobi., 1990-06)
Six genera of bacteria: Serratia, Providencia, Enterobacter, Aeromonas, Cedecea and Bacillus were isolated from field-collected G. pallidipes. Four genera: Serratia, Providencia, Enterobacter and Aeromonas were isolated ...
Parasitism of Amblyomma variegatum by a Hymenopteran Parasitoid in the Laboratory, and Some Aspects of Its Basic Biology
(University of Nairobi., 1994-06)
Unfed Amblyomma variegatum F. nymphs were experimentally infected in the laboratory with a hymenopteran parasitoid, Ixodiphagus hookeri (Howard). The parasitoid was originally obtained from ticks collected from cattle in ...
Characterization of Amblyomma variegatum tick saliva and salivary gland antigens inducing anti-tick immunity in Boran cattle
(University of Nairobi., 1998)
The sequence of proteins synthesized during the feeding of Amblyomma variegatum and humoral resistance acquired by Boran cattle when exposed to A. variegatum infestations were studied. Resistance was induced by repeatedly ...
Horizontal transmission of mycotic infection in adult tsetse,Glossina morsitans morsitans
(University of Nairobi., 1990)
AdultGlossina morsitans morsitans exposed to wet conidia ofBeauveria bassiana andMetarhizium anisopliae suffered high mortalities ranging from 90 to 100% by 2 weeks post-exposure. Infected ♂ ♂ maintained in the same cages ...
