Selection of Beauveria bassiana (Bals.) Vuill. and Metarhizium anisopliae (Metsch.) Sorok. strains for control of Cornitermes cumulans (Kollar)

Abstract

ABSTRACT

Physiological and antioxidant response by Beauveria bassiana Bals (Vuill.) to different oxygen concentrations

“…Conidia are the most efficient propagules during infection, and are produced mainly by culture on agricultural products and byproducts such as rice (Kang et al 2005;Neves and Alves 2000;Ye et al 2006). Conidia production is influenced by culture conditions such as aeration and moisture (Issaly et al 2005;Nuñez-Gaona et al 2010).…”

Molecular characterization and virulence of Beauveria bassiana and Metarhizium anisopliae against Galleria mellonella (Lepidoptera: Pyralidae) and Tenebrio molitor (Coleoptera: Tenebrionidae) larvae

“…G. mellonella and T. molitor are known to be susceptible to B. bassiana and M. anisopliae, for this reason they have been used as baits for isolation of entomopathogenic fungi from the soil (Zimmerman, 1986;Bidochka et al, 2002;Montesinos et al, 2011) or, as a probe to pathogenicity of other insect species (Bharadwaj et al, 2011). Mortality and concentrations were considered parameters in the study of the best strains behavior once indicating the pathogen colonization capacity, surpassing all competitor agents present in the insect (Neves, 1998). It was observed that it requires less inoculums amount by Bb79MI B. bassiana and Ma58MI M. anisopliae treatments to kill the G. mellonella and T. molitor larvae.…”

“…This fact was also observed by other authors studying M. anisopliae and B. bassiana strains on different insect species (Filho et al, 2002;Silva et al, 2003;Cunha et al, 2008). According to Neves and Alves (2000), as more conidia penetrating, more toxins or enzymes are released, increasing the insect mortality. However, the fungus action speed depends, besides the concentration, of the host species involved (Sosa-Gomez and Moscardi, 1992).…”

Entomopathogenic Effect of Beauveria bassiana (Bals.) and Metarrhizium anisopliae (Metschn.) on Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae)Larvae Under Laboratory and Glasshouse Conditions in Ethiopia

“…Our results also indicated the potential of B. bassiana and M. anisopliae to control the larvae of T. absoluta in an integrated pest management programs. Neves and Alves [22] also noted, as more conidia penetrating, more toxins or enzymes are released, increasing the insect mortality. Though, the fungus action speed depends, besides the concentration, of the host species involved [23].…”
