The results show … …American Journal of Environmental Sciences, Vol. 3, Issue 1 · 31 Mar 2007 · 7,392 accessesView PDFCite
Review ArticleOpen accessIn the keywordsUse of Entomopathogenic Fungi as Biopesticides to Manage Insect Pest: A ReviewAnthony Emaru, Jane Gesimba Nyaanga, Saidi MwanarusiEntomopathogenic Fungi (EPF) biopesticides are more environmentally friendly and are an alternative to toxic synthetic chemicals. Due to EPF's pathogenic nature to various arthropod pests, it is thus considered a primary candidate for an integrated biological approach due to its numerous invaluable effects. However, an urgent need is to develop an environmentally safer, more sustainable, and practical approach to managing … …American Journal of Applied Sciences, Vol. 21, Issue 1 · 12 Jul 2024 · 8,015 accessesView PDFCite
InvestigationOpen accessIn the keywordsFeatures of Distribution, Harmfulness and Control of the Population of the Eriosoma Lanigerum Hausm.
