“…Isolates of B. bassiana and M. anisopliae s.l. exhibit high genetic and virulence diversity [27, [36][37][38][39][40]. Comparative genomic analyses for both genera have revealed qualitative differences in gene content that are potentially important in determining host virulence [41][42][43][44][45].…”

Entomopathogenic fungi (EPF) are the natural enemies of insect-pests. However, EPF recoveries can be influenced by the soil habitat-type(s) incorporated and/or the bait-insect(s) used. Galleria mellonella (GM) as bait-insect, i.e. 'Galleria-bait', is arguably the most common methodology, which is sometimes used solely, to isolate EPF from soils. Insect baiting using Tenebrio molitor (TM) has also been employed occasionally. Here 183 soils were used to estimate the functional diversity of EPF in Portuguese Douro vineyards (cultivated habitat) and adjacent hedgerows (semi-natural habitat), using the TM bait method. Moreover, to study the effect of insect baiting on EPF recovery, 81 of these 183 soil samples were also tested for EPF occurrences using the GM bait method. Twelve species were found in 44.26% ± 3.67% of the total of 183 soils. Clonostachys rosea f. rosea was found in maximum soils (30.05% ± 3.38%), followed by Beauveria bassiana (12.57% ± 2.37%), Purpureocillium lilacinum (9.29% ± 2.14%) and Metarhizium robertsii (6.01% ± 1.75%). Beauveria pseudobassiana (P < 0.001), C. rosea f. rosea (P = 0.006) and RESEARCH ARTICLELav Sharma et al. / MycoKeys 38: 1-23 (2018) 2 Cordyceps cicadae (P=0.023) were isolated significantly more from hedgerows, highlighting their sensitivities towards agricultural disturbances. Beauveria bassiana (P = 0.038) and M. robertsii (P = 0.003) were isolated significantly more using GM and TM, respectively. Principal component analysis revealed that M. robertsii was associated both with TM baiting and cultivated habitats, however, B. bassiana was slightly linked with GM baiting only. Ecological profiles of B. bassiana and P. lilacinum were quite similar while M. robertsii and C. rosea f. rosea were relatively distant and distinct. To us, this is the first report on (a) C. cicadae isolation from Mediterranean soils, (b) Purpureocillium lavendulum as an EPF worldwide; and (c) significant recoveries of M. robertsii using TM over GM. Overall, a 'Galleria-Tenebrio-bait method' is advocated to study the functional diversity of EPF in agroecosystems.

“…Considering the abundance and diversity of EPFs in soils of temperate regions, it is possible to confirm that Beauveria bassiana (Balsamo) Vuillemin and Metarhizium anisopliae (Metsch.) Sorokin are the most abundant species (Perez-Gonzales et al 2014).…”

Entomopathogenic fungi (EPFs) play an important role for regulating insect pest populations, as they exist in many different ecosystems. Within these fungi, Beauveria and Metarhizium spp. genera include species that are the most commercially important. The aim of this study was to determine the diversity and distribution of Beauveria and Metarhizium spp. in walnut fields of Kırşehir, Turkey, and to evaluate their pathogenicity against Cydia pomonella (L.) (Lepidoptera: Tortricidae). To perform this, 90 soil samples were collected from walnut fields where Beauveria and Metarhizium spp. were isolated from these soils, using selective media. The isolated 40 fungi were characterized based on their morphological and molecular characteristics including Bloc and β-tubulin gene sequences. Also, eight selected fungi were tested against C. pomonella larvae under laboratory conditions. The fungal isolates were identified as Beauveria pseudobassiana (15), B. bassiana (12), Metarhizium robertsii (11), and M. brunneum (13). M. brunneum ELA-38 caused 83% mortality within 2 weeks after application of 1 × 10 8 conidia/ml. Consequently, Beauveria and Metarhizium spp. are the common component of the soils collected from walnut fields and some of fungi obtained from this work might be beneficial in the future biological control programs of C. pomonella.
