Interaction of fungicides with the entomopathogenic fungusIsaria fumosorosea
Biocontrol Science and Technology, 2011Abstract The effects of eight commonly used fungicides: propamocarb, fenarimol, triadimefon, procimidone, azoxystrobin, carbendazim, cooper oxychloride and Trichoderma harzianum on germination, mycelial growth and virulence of Isaria fumosorosea (Wize) Brown & Smith (Ascomycota: Hypocreales) was studied.

Antioxidant enzyme influences germination, stress tolerance, and virulence of Isaria fumosorosea
Journal of Basic Microbiology, 2012AbstractAntioxidizing enzymes (superoxide dismutase, catalase, and glutathione peroxidae) are important enzymatic systems used to degrade hydrogen peroxide into water and oxygen, thereby lowering intracellular hydrogen peroxide levels. Entomopathogenic fungi display increased activities of antioxidizing enzymes during growth and germination, which is ...

The adipokinetic hormones (AKHs) are known to be involved in insect immunity, thus their role in the cockroach Periplaneta americana infected with the entomopathogenic fungus Isaria fumosorosea was examined in this study. The application of I. fumosorosea resulted in a significant increase in both Akh gene expression and AKH peptide levels. Further, co-

The filamentous fungus, Isaria fumosorosea, is a promising insect biological control agent. Chitinases have been implicated in targeting insect cuticle structures, with biotechnological potential in insect and fungal control. The I. fumosorosea chitinase gene, Ifchit1, was isolated and determined to encode a polypeptide of 423 amino acids (46 kDa, pI =

Laboratory evaluation of Isaria fumosorosea against Spodoptera littoralis.
Communications in agricultural and applied biological sciences, 2013Isaria fumosorosea (syn. Paecilomyces fumosoroseus) is potentially useful for the biological control of economically important agricultural and forest insect pests. We evaluated efficacy of two strains of this entomopathogenic fungus against last instar larvae and pupae of Egyptian cotton leafworm, Spodoptera littoralis.

Long-term persistence of entomopathogenic fungi as biopesticides is a major requirement for successful industrialization. Corn oil carrier was superior in maintaining germination rates of Isaria fumosorosea SFP-198 conidia during exposure to 50°C for 2 h, when compared with other oils, such as soybean oil, cottonseed oil, paraffin oil, and methyl ...

Abstract Extracellular chitinase production by the entomopathogenic fungus, Isaria fumosorosea IF28.2 was studied by using submerged fermentation. Maximum chitinase production (178.34±3.91 mU/mL) was obtained when fermentation was carried out at 25°C for 120 h using 72-h-old mycelium in a medium.

AnIsaria fumosoroseaSCAR marker for evaluation of soil, insect, and airborne samples
Biocontrol Science and Technology, 2011Abstract Molecular detection markers are needed for ecological studies of entomopathogenic fungi. In this study, a sequence-characterized amplified region (SCAR) marker of Isaria fumosorosea was used to detect the fungus in soil, insects, and airborne samples. These were artificially added with different fungal conidial concentrations.

Entomopatogenní houba Isaria fumosorosea
2014Entomopathogenic fungus Isaria fumosorosea is among the species of entomopathogenic fungi used in biological control. Species I. fumosorosea has wide host range of insects in which is able to cause the primary diseases. Fungus I. fumosorosea most often infects greenhouse pests, such as aphids, thrips and mealybugs. I.

Effect of the entomopathogenic fungus Isaria fumosorosea on physiological processes in insects
2020The project is focused on a study of the infection elicited by entomopathogenic fungus (EPF) Isaria fumosorosea in two model species - the firebug Pyrrhocoris apterus and cockroach Periplaneta americana - and a role of adipokinetic hormones (AKHs) during that.
