“…Majority of the isolates were obtained from the soil with pH ranging between 8.2-8.5. The similar findings were observed by QuesadaMoraga et al [26], who reported greatest percentage of fungal isolation in the soil samples with pH value 8-8.5. On the contrary, Ali-Shtayeh et al [27], reported minor effect of pH on ENPF abundance in the cultivated soils.…”

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.

“…Entomopathogenic fungi were detected in all the 9 sub-simples analyzed (100%). Comparable results were found in the Moroccan endemic forests of Argania spinosa (91.62%) [16], but higher than in other countries: over 71.7% in Spain [28,34], 55.5% in China [35], 43% in Southern Italy [36], 33.6% in Palestine [37], 20.59% in Turkey [22] and 17.5% in the UK [21]. These comparisons must be taken with precautions because in all this studies the numbers and the type of larvae and number of repetitions used to trap entomopathogenic fungi from soil samples were different.…”

Abstract:The present study forms a part of biological control against the medfly (Ceratitis capitata) and seeks to isolate and determine the diversity of the medfly-associated entomopathogenic fungi in soil samples collected from Argane (Argania spinosa) forest, in different localities of Souss-Massa region. Search and isolation of the indigenous populations of Ceratitis capitata entomopathogenic fungi was carried out by using larvae of this pest as baits. After trapping, isolation and identification of fungal isolates, a pathogenicity test was used to select fungal strains that have significant virulence potential against the Mediterranean fruit fly. The degree of virulence was estimated by the ability of the fungus to induce the disease and/or the death in the insect and also by calculating the lethal time 50 (LT50). The obtained results were clearly demonstrated the sensitivity of medfly to tested fungal strains and particularly to strains of Fusarium sp., Aspergillus niger and Scopulariopsis sp. that have shown high mortality rates (more than 84%) and to Trichoderma harzianum, Scedosporium sp., Epicoccum sp. and Ulocladium sp. with more than 70% mortality for the two tested concentrations. Furthermore these strains showed short LT 50 (less than 83 hours). All these results confirm the presence of entomopathogenic fungi of Ceratitis capitata in Argane soil, and prove the potential of entomopathogenic fungi for biocontrol of the Mediterranean fruit fly under laboratory conditions.

“…A different species structure of Beauveria was presented by Medo (2009) (Medo 2009). On the other hand, habitat preference of entomopathogenic fungi is well known and supported by several studies (Vanninen 1996;Bidochka et al 1998;Quesada-Moraga et al 2007). Generally, a more common and frequently identified Beauveria species from insect hosts is B. bassiana.…”

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.
