“…This result corresponded to previous reports showing that Lecanicillium sp. exhibited higher virulence against aphids than other fungal strains (Alavo et al, 2001;Loureiro and Moino, 2006;Åsman, 2007;Diaz et al, 2009). …”

“…Comparison of the lethal effects of different isolates used by other authors (Alavo et al 2001;Askary et al 1998;Å sman 2007;Diaz et al 2009;Fournier and Brodeur 2000;Kim et al 2007;Loureiro and Moino 2006;Safavi et al 2002;Sugimoto et al 2003) is difficult since the mode of distribution of the fungus and experimental conditions vary greatly, and different aphid species and developmental stages were considered. In addition the recent split of the species V. lecanii into different species (Zare and Gams 2001) make the comparison even more difficult.…”

“…Recently entomopathogenic fungi belonging to the species Verticillium lecanii have been attributed to a new genus, Lecanicillium, and in addition split into different species (Zare and Gams 2001). Fungi belonging to this genus are known to be pathogens of aphids (Alavo et al 2001;Askary et al 1998Askary et al , 1999Å sman 2007;Diaz et al 2009;Feng et al 1990;Fournier and Brodeur 2000;Kim et al 2007;Loureiro and Moino 2006;Safavi et al 2002;Shah and Pell, 2003;Steenberg and Humber 1999;Sugimoto et al 2003;Vu et al 2007) and consequently have been considered as candidates for biological control. In addition, fungi of the Lecanicillium genus have been discovered as being active against fungal plant pathogens suggesting that such entomopathogens could be developed as a dual-role mycopesticide .…”

Effects of the fungus Lecanicillium lecanii on survival and reproduction of the aphid Schizaphis graminum

This study investigated the effects of a strain of the fungus Lecanicillium lecanii (Zimm.) Zare and Gams (Hypocreales: Ascomycota) on the aphid Schizaphis graminum (Rondani) (Hemiptera: Aphididae). The fungus was administered to fourth instar nymphs and to alate and apterous adult morphs as a ground rice-kernel formulation. This study showed that L. lecanii formulation affected the survival of the aphids and interacted differently with the studied morphs, the Lethal Time values being lower for alate compared to apterous morphs and nymphs. The treatment also caused a significant reduction in the fecundity of the three treated aphid groups. Histological analysis revealed that the hyphae invaded the host hemocoel of a limited number of alate and apterous morphs: the fungus only entered through the spiracles. Scanning Electron Microscope observations revealed that L. lecanii adhered to the body surface of both adults and nymphs without differentiation. In conclusion, the present study suggests that this strain might be a good candidate for a programme of biological control of S. graminum and other aphid species.

“…Verticillium genera have two important species, V. lecanii and V. chlamydosporium. V. lecanii controls nymphs and adults of different aphids such as M. persicae, Aphis gossypii, Brevicoryne brassicae, and T. vaporariorum; a variety of strains have been tested to infect aphids, including the effects of additives to improve virulence [152,153].…”

Chemical fertilizers, pesticides, and fungicides are widely used in agriculture to improve crop yields. Most of the compounds used are synthetic, and their overuse causes environmental pollution and human health problems. Currently, several countries are working to reduce the use of agrochemicals. Organic agriculture is now emerging as a sustainable alternative to traditional agriculture using environmentally friendly strategies such as the application of organic fertilizers from plant and animal waste and pesticides based on plant extracts and microbials. However, the availability of commercial biopesticides and organic fertilizers is very limited because there are certain barriers to the commercialization of biological products. These barriers include small available quantities of raw materials and strict registration laws requiring toxicological tests and other studies that are expensive and time consuming. The objective of this review is to provide details about the various organic fertilizers and pesticides that do not have the same disadvantages as synthetic compounds in terms of persistence and toxicity.
