“…used for control of many important pests of various crops around the world (Varela and Morales, 1996). Keeping in view the above facts and need for search of effective biointensive control measures, it was decided to evaluate the acaricidal activity of leaf extract of W. somnifera, stem extract of G. glabra and B. bassiana against T. urticae on cucumber, a major vegetable crop and potential host for the pest.…”

Field trials were conducted to evaluate the acaricidal potential of entomopathogenic fungus, Beauveria bassiana and aqueous extracts of Withania somnifera and Glyccirrhyza glabra against the mobile stages of Tetranychus urticae Koch on cucumber. The treatments responded in a concentration dependent manner. Highest reduction in T. urticae population was achieved with Omite (0.05%) followed by Nimbecidine (5ml/l), B. bassiana (10 10 spores ml -1

“…Similarly, Varela and Morales [29] reported wide variation (between white and yellow) in colony color of different B. bassiana isolates. Liu et al [30], reported variation in spore production (1.6 × 10 6 -1.56 × 10 7 spores/cm 2 ) for the four isolates of B. bassiana, with the most virulent isolate producing significantly larger number of spores.…”

Background: The house fly, Musca domestica L. is a major pest of medical and veterinary significance which due to their ubiquitous lifestyle and broad food preference achieves a very high density in favorable climatic conditions of Indian subcontinent. This has led to several instances of severe health condition among human and animal population, calling attention towards M. domestica control through existing and innovative methods. Use of biological control agent, such as entomopathogenic fungi (ENPF) for M. domestica control has shown potential, and need to be further explored for the newer isolates suited to particular environment for greater efficacy. The present study attempted the isolation and identification of native ENPF strains suitable for M. domestica control.

“…This was also observed in the present bioassays, when the isolates of non-leaf miner origin (BOV, END-BB, and SO-MA) demonstrated a lower virulence. Faster growing isolates are considered to have an advantage as biocontrol agents because this allows less time needed for inoculum production, provides a competitive domination over other microorganisms during a saprophytic stage of pathogenesis, and shortens infection cycle in hosts which can make the pest control more effective (Varela & Morales 1996). In our laboratory study, mycelial growth rate of tested isolates correlates with mean survival time and cumulative mortality of pupae.…”

Schemmer R., Chládeková P., Medo J., Barta M. (2016): Natural prevalence of entomopathogenic fungi in hibernating pupae of Cameraria ohridella (Lepidoptera: Gracillariidae) and virulence of selected isolates. Plant Protect. Sci., Spontaneous infection of hibernating Cameraria ohridella pupae by entomopathogenic fungi was monitored at two localities of south-western Slovakia and efficacy of selected fungal isolates against the pupae was evaluated in laboratory. Natural prevalence of fungal infection in pupal populations was low (< 7%) and varied depending upon collecting date, locality, year, and pathogen. Ten isolates of three fungal species, Beauveria pseudobassiana, Isaria fumosorosea, and I. farinosa, isolated from the naturally infected pupae and three isolates of non-insect origin of two fungi, B. bassiana and metarhizium anisopliae, were screened for colony growth, conidial production in vitro, and virulence to C. ohridella pupae. A significant variability in the evaluated traits was detected among the isolates. Pupae demonstrated vulnerability to all the isolates irrespective of their origin, however virulence of isolates varied significantly. I. fumosorosea was the most virulent fungus with median lethal concentration of 0.09 × 10 4 conidia/ml (isolate CO10-IFu) and mean survival time of pupae of 7.14 days (isolate CO8-IFu). No correlation between conidial yield of isolates and fungal virulence was observed, but a moderately strong relationship was detected between virulence and mycelial growth rate of isolates.
