Research ArticleOpen accessEvery word in the titleEffect of Essential Oil from Citronella and Alfazema on Fennel Aphids Hyadaphis foeniculi Passerini (Hemiptera: Aphididae) and its Predator Cycloneda sanguinea L. (Coleoptera: Coccinelidae)Charles I. Abramson, Paulo A. Wanderley, Maria J.A. Wanderley et al.The essential oil of plants is used as an alternative to pesticides for the control of aphids. We study the effect of the essential oils of citronella and alfazema on aphid populations in the laboratory and in the field. We also investigate the effect of these oils on the behavior of the aphid’s principal predator the ladybug. The results show … …American Journal of Environmental Sciences, Vol. 3, Issue 1 · 31 Mar 2007 · 7,392 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSELECTION OF BEAUVERIA BASSIANA (BALSAMO) VUILLEMIN ISOLATES FOR MANAGEMENT OF MYZUS PERSICAE (SULTZAR) (HOM.: APHIDAE) BASED ON VIRULENCE AND GROWTH RELATED CHARACTERISTICSMohammad S. Al-alawi, Maher ObeidatIsolates of the entomopathogenic fungus Beauveria bassiana originated from Jordan were evaluated for their efficacy against the green peach aphid, Myzus persicae under laboratory and greenhouse conditions. Efficacy evaluation involved testing all isolates at a concentration of 1×107 conidia/mL followed by concentration dependent and greenhouse bioassays for the top virulent isolates. Growth characteristics related to virulence were evaluated for high, … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 1 · 28 Dec 2013 · 7,943 accessesView PDFCite
Research ArticleOpen accessIn the keywordsThe Impact of Climate Factors on the Epidemiology and Management of Potato virus YMahabuba Mostafa, Md. Motaher HossainPlant viruses give rise to potential loss to global crop production and have the potential to cause widespread damage. Potato virus Y (PVY) is a plant virus that belongs to the genus Potyvirus and the family Potyviridae and it is considered a major concern, particularly for solanaceous crops such as potatoes. PVY represents the largest cluster of plant viruses, encompassing … …OnLine Journal of Biological Sciences, Vol. 24, Issue 4 · 31 Aug 2024 · 4,758 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

EditorialOpen accessIn the abstractThe Timeless Contribution of Rootstocks towards Successful Horticultural Farming: From Ancient Times to the Climate Change EraIoannis E. PapadakisGrafting is a horticultural practice by which living vegetative plant organs (root, stem and/or buds) of either the same genotype or, usually, different genotypes belonging to the same species, genus, subfamily and/or family, are tightly connected to each other to form a double-compound plant. In fact, it is a method of asexual (clonal-vegetative) propagation of plants. The basal part of … …American Journal of Agricultural and Biological Sciences, Vol. 11, Issue 4 · 16 Dec 2016 · 9,521 accessesView PDFCite
