“…A high relative abundance of B. pseudobassiana (56%) was also reported among the Beauveria spp. infecting the pollen beetle Meligethes aeneus in Switzerland (Meyling et al, 2012). Information from our survey and previous reports (Rehner and Buckley, 2005;Ghikas et al, 2010;Meyling et al, 2012) indicate B. pseudobassiana has a wide host range but there could be genotypes within the species that may be selective for specific hosts.…”

“…Extensive overlap in morphological characteristics among B. australis, B. bassiana, B. kipukae, B. pseudobassiana, and B. varroae limits their utility for species identification . Phylogenetic assignment of Beauveria isolates to specific species can be accomplished by sequencing the genomic DNA regions of the internal transcribed spacer (ITS) region of the ribosomal RNA gene (White et al, 1990), the 5 0 end of Elongation Factor 1-alpha (EF1-a) (Rehner and Buckley, 2005;Rehner et al, 2006), the intergenic Bloc region (Rehner et al, 2006Meyling et al, 2009Meyling et al, , 2012, RNA polymerase II largest subunit (RPB1) and RNA polymerase II subunit second largest subunit (RPB2) , and mitochondrial intergenic regions such as nad3-atp9 and atp6-rns (Ghikas et al, 2010).…”

The microbiota present in Stomoxys calcitrans larvae may assist their survival in contaminated environments through production of inhibitory substances. Bacteriological identification methods, the polymerase chain reaction (PCR) and scanning electron microscopy (SEM) were used to detect a bacterium naturally present in mucus and macerated S. calcitrans larvae. The antifungal activity was determined based on the results from disk diffusion tests on an artificial solid medium. The bacterium was identified as Stenotrophomonas maltophilia and presented antifungal activity against Beauveria bassiana sensu lato isolates CG 138, CG 228 and ESALQ 986. This result suggests that the larval microbiota is a factor that can compromise the use of B. bassiana s.l. fungus for biological control of S. calcitrans larvae.Keywords: Stenotrophomonas maltophilia, Stomoxys calcitrans, antifungal activity. ResumoA microbiota presente em larvas de Stomoxys calcitrans pode auxiliar na sua sobrevivência em ambientes contaminados, devido à produção de substâncias inibidoras. Métodos bacteriológicos de identificação, reação em cadeia da polimerase (PCR) e microscopia eletrônica de varredura (MEV) foram utilizados para detectar uma bactéria naturalmente presente no muco e macerado de larvas de S. calcitrans. A atividade antifúngica foi baseada nos resultados obtidos no teste de difusão em meio sólido artificial. A bactéria foi identificada como Stenotrophomonas maltophilia e apresentou atividade antifúngica contra os isolados CG 138, CG 228 e ESALQ 986 de Beauveria bassiana sensu lato. Estes resultados sugerem que a microbiota larval é um fator que pode comprometer o uso de B. bassiana s.l. no controle biológico de larvas de S. calcitrans.

The entomopathogenic fungus Beauveria bassiana (Balsamo 1835) Vuillemin is an effective alternative control agent against some agricultural pests and biological vectors of important diseases such as Chagas disease. In this work we studied an isolate of Beauveria bassiana from of the town of San Antonio Rayón, Puebla, Mexico and its entomopathogenic effects on Meccus pallidipennis (Stal 1872). Phylogenetic analysis using molecular comparison of the ITS and EF1α genes, showed that the resulting cladogram places the BUAP 04 strain with a relationship closer to the AFAO 9-6 strain, within the diversity of the B. bassiana sensu lato group. Although there was the possibility that BUAP 04 strain was a direct descendant of strains used in campaigns of biologic control, molecular study allowed us to recognize that it was a different fungus due to numerous inserts. A strain isolated from a T. dimiata was evaluated for pathogenicity against another triatoma (Meccus pallidipennis) species obtaining an LC50 of 4.16 × 106 spores/mL, confirming that the BUAP 04 strain is virulent for M. pallidipennis and could be a good prospect for formulations to control M. pallidipennis.
