Photostabilization of an Entomopathogenic Fungus Using Composite Clay Matrices¶
Photochemistry and Photobiology, 2003To provide photostabilization for entomopathogenic fungi by anionic dyes, composite matrices based on clay-biopolymer combinations were prepared. In the first step, the negative surface charge of various clays (montmorillonite, attapulgite, bentonite and kaolinite) was reversed to positive by adsorption to the polycationic biopolymer chitosan.

Synthesis of the Entomopathogenic Fungus Metabolites Militarinone C and Fumosorinone A
The Journal of Organic Chemistry, 2018Militarinone C and fumosorinone A, 3-oligoenoyltetramic acids produced by insect pathogenic fungi, were synthesized for the first time. The pyrrolidine-2,4-dione ring was closed through a late-stage Dieckmann condensation of N-(β-ketoacyl) derivatives of tyrosine, obtained by its acylation with either thioesters or Meldrum's acid derivatives bearing ...

Role of Entomopathogenic Fungus in Pest Management
2014Insect pests cause enormous damage to our crops. However, insects like other living things have their enemies in nature. Microorganisms like fungi, bacteria, and viruses also play a vital role in checking the insect population. Among which fungi parasitize the insects and cause severe epizootics than bacteria and viruses, and it is distributed ...

Double-stranded RNA in the entomopathogenic fungus Metarhizium flavoviride
Current Genetics, 1999Bands of dsRNA were detected in five out of seven isolates of the entomopathogenic fungus Metarhizium flavoviride. The identity of these bands was proven by RNase and S1-nuclease treatments. The transference of dsRNA between isolates (from CG291 to CG442) was successfully carried out through forced heterokaryons. Isogenic strains, with or without dsRNA,

Genetic Transformation and Mutagenesis of the Entomopathogenic Fungus Paecilomyces fumosoroseus
Journal of Invertebrate Pathology, 1999We have developed a DNA-mediated transformation system for the entomopathogenic fungus Paecilomyces fumosoroseus based on resistance to the herbicide glufosinate ammonium. The resistance is provided by the bar gene from Streptomyces hygroscopicus and is under the control of the Aspergillus nidulans trpC promoter and terminator sequences. Frequencies of

Investigations on the destruxin production of the entomopathogenic fungus Metarhizium anisopliae
Journal of Invertebrate Pathology, 2004The dynamics of cyclic peptide destruxins (dtxs) produced by Metarhizium anisopliae strains V245 and V275 were monitored both on solid and in liquid media. The results showed that both strains did not produce dtxs in large-scale fermenter cultures or solid Czapek Dox (CD) agar.

Genes involved in virulence of the entomopathogenic fungus Beauveria bassiana
Journal of Invertebrate Pathology, 2016Pest insects cause severe damage to global crop production and pose a threat to human health by transmitting diseases. Traditionally, chemical pesticides (insecticides) have been used to control such pests and have proven to be effective only for a limited amount of time because of the rapid spread of genetic insecticide resistance.

To test the suitability of the Agrobacterium tumefaciens-mediated transformation (AMT) method with Paecilomyces fumosoroseus, a fungal pathogen that causes diseases in a wide range of insects including whiteflies.Conidia of P. fumosoroseus were successfully transformed to hygromycin B resistance using the hph gene of Escherichia coli as the selectable ...

Immunochemical characterization of the entomopathogenic fungus Beauveria bassiana
Journal of Invertebrate Pathology, 1991Abstract Analysis by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) of crude extracts from the mycelium of five Beauveria bassiana isolates contained several proteins which were used to produce antibodies in BALB/c mice. The antibody response to these proteins was good and enzyme-linked immunoassay showed a wide antigenic ...

Interactions of Entomopathogenic Fungus with Entomophagous Insects in Agroecosystems
2019The use of entomopathogenic biopesticides, either as spore suspensions or formulated solid products, can have several collateral effects in agroecosystems. Fungal entomopathogens are typically applied as inundative sprays and are expected to result in short-term pest control, not only against specific pests, but also against species that occupy the ...
