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.

“…While bacteria and viruses must be ingested to cause disease, fungi can cause infection by penetrating the outer structure of insects (Khetan 2001). There are many commercial products available worldwide, most based on fungi from six to seven species from Hyphomycetes such as Beauveria bassiana, Metarhizium anisopliae and Paecilomyces fumosoroseus (Goettel et al 2005;Sevim et al 2012c).…”

Eurygaster integriceps (Hemiptera: Scutelleridae) is one of the most serious pest of wheat and other cereal crops throughout the Near and Middle East including Turkey. To contribute biological control of this pest, we investigated the culturable bacterial flora of E. integriceps and their virulence against it. We also tested different entomopathogenic fungi (Isaria fumosorosea ARSEF8356, Beauveria bassiana ARSEF8356, Metarhizium brunneum ARSEF8671 and Nomurae rileyi ARSEF1670) against this pest under laboratory conditions. Bacterial isolates were characterized based on morphological, biochemical, physiological and molecular characteristics (16S rRNA sequencing). The isolates were identified as Pantoea sp. (S1, S5, S7, S8, S10 and S11), P. agglomerans (S2, S3 and S4), Pseudomonas sp. S6 and Micrococcus luteus S9. The highest mortality within bacterial isolates was observed from Pantoea sp. S1, P. agglomerans S4 and Pantoea sp. S7 with 100%. Mortality of other bacterial species ranged from 33% to 88%. The highest mortality among the tested entomopathogenic fungi was obtained from Isaria fumosorosea ARSEF 8333 with 100%. Mortality of other fungi ranged from 33% to 50%. Consequently, Pantoea sp. S1, P. agglomerans S4, Pantoea sp. S7, Beauveria bassiana ARSEF 8356 and Isaria fumosorosea ARSEF 8356 seem to be promising candidates in the control of E. integriceps.

Beauveria bassiana is an entomopathogenic fungus that has been well known for its capacity to act as biopesticide on various disease vectors. The analysis of organic extracts of strains CG71 and UNI40 led to identification of cyclodepsipeptides beauvericin, beauvericin A or F, beauvericin E and bassianolide by ultra-high pressure liquid chromatography-high resolution mass spectrometry in tandem mode (UHPLC-HRMS/MS). The larvicidal activity on 3 rd instar of Aedes aegypti revealed LC 50 0.9887 and 0.4653 ppm in 24 and 48 hours (CG71 methanolic extract), LC 50 0.7834 ppm in 48 hours (CG71 ethyl acetate), LC 50 0.7834 and 1.8149 ppm (UNI 40 for ethyl acetate and methanolic extracts, respectively) in 48 hours. These findings highlight the potential of B. bassiana metabolites for controlling the vector of Dengue and Zika diseases. Keywords: cyclohexadepsipeptides, Dengue, Zika, beauvericins, UHPLC-HRMS/MS IntroductionThe entomopathogenic Beauveria bassiana has a broad host range naturally attacking insects and variety of arthropod species. [1][2][3] Due to this ability, it is used as a biopesticide agent on diverse disease vectors, including crop pests, ticks and mosquitoes. 4,5 The attack on insect cuticle occurs after hyphae of B. bassiana penetrate the insect integument by enzymatic action. 6 Species of entomopathogenic fungi have been described as producers of secondary metabolites, including bioactive non-ribosomal peptides and polyketides. 7 B. bassiana produces the cyclooligomer nonribosomal depsipeptides beauvericins and bassianolide, 8,9 beauveriolides, 10 D, E and F. 25 Bassianolide is another cyclooctadepsipeptide metabolite produced B. bassiana and Lecanicillium lecanii. 9 It is toxic to insects and probably also acts as an ionophore, such as other cyclodepsipeptides. 15 The structural diversity of metabolites from entomopathogenic fungi, associated with diverse biological activities, stimulates the research by on bioactive fungal extracts for controlling insect pests and disease vectors.Larvicidal Activity of Beauveria bassiana Extracts against Aedes aegypti and Identification of Beauvericins J. Braz. Chem. Soc. 1004 Dengue is a viral infection transmitted to humans by Aedes aegypti mosquitoes that became a major concern of the public health sector. 26 There were 96 million apparent dengue infections globally in 2010, of which the Americas contributed 14% (13 million infections) of worldwide and over half developed in Brazil and Mexico. 27 Due to no effective antiviral agents and licensed vaccine for infection, the decrease in transmission depends only on vector control by elimination of artificial and disposable water inundated larvae breeding sites and application of insecticides. 27,28 Furthermore, studies reveal resistance in the vector population to various substances, in Brazil there is an irregular distribution of insecticide resistance. 28 Furthermore, Aedes mosquitoes also transmit Zika virus; attracting worldwide attention in 2016, when the vector caused widespread epidemic cases in Braz...
