Beauveria bassiana (Balsamo) Vuillemin, an entomopathogenic fungus, can exist asymptomatically as an endophyte in banana (Musa spp.) and potentially provide management against the banana weevil Cosmopolites sordidus (Germar). However, in order to optimize its biological control potential when dep...

Twenty isolates of four species of entomopathogenic hypocrealean fungi (Beauveria bassiana, Beauveria brongniartii, Isaria farinosa, and Metarhizium anisopliae) were found to be pathogenic to adults of the Asian longhorned beetle, Anoplophora glabripennis. Survival times for 50% of the beetles te...

The entomopathogen Beauveria bassiana (Balsamo) Vuillemin (Ascomycota: Hypocreales) survives as an endophyte in a wide range of plants, offering substantial protection against tunneling insect pests. Although current research indicates that the fungus can live as an endophyte in tissue-cultured b...

Effect of endophytic Beauveria bassiana on populations of the banana weevil, Cosmopolites sordidus, and their damage in tissuecultured banana plants
Endophytic fungi colonize most plants, causing no damage to their hosts, and often extending benefits, such as enhanced protection against various biotic and abiotic constraints. In the current study, three experiments assessed the activity of secondary metabolites of three strains of endophytic ...

In vitro nematicidal effect of endophytic Fusarium oxysporum against Radopholus similis, Pratylenchus goodeyi and Helicotylenchus multicinctus
Endophytic colonization by the fungus Fusarium oxysporum can result in increased host resistance topests and diseases, and greater biomass production. However, few studies have assessed the field performanceof this fungus for biological control of pests and diseases in banana. Further to greenhou...

Use of 50 × 500 mm non-woven fiber bands impregnated with cultures of entomopathogenic fungi was investigated for control of Anoplophora glabripennis. Fungal bands produced as a commercial pest control product and obtained from industry contained Beauveria brongniartii NBL 851 while lab-produced ...

The burrowing nematode (Radopholus similis (Cobb) Thorne) and the banana weevil (Cosmopolites sordidus Germar, Coleoptera: Curculionidae) are major pests of banana (Musa spp.) in the Lake Victoria basin region of Uganda. Among biological options to control the two pests is the use of non-pathogen...

The amaranth leaf-webber, Spoladea recurvalis (Fabricius; Lepidoptera: Crambidae), is a serious pest of Amaranthus sp. in Africa and Asia. Apanteles hemara (Nixon; Hymenoptera: Braconidae) is by far the most important larval endoparasitoid of the amaranth leaf-webber. We examined the effects of h...

Under laboratory conditions, nonpathogenic, endophytic Fusarium oxysporum inflicts high mortality among banana weevils and nematodes. Following inoculation into banana (Musa spp.) tissue cultured plants, successful colonisation is necessary for efficient biological control of these pests. The pat...
