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 efficacy of silver generated larvicide with the help of entomopathogenic fungi, Isaria fumosorosea (Ifr) against major vector mosquitoes Culex quinquefasciatus and Aedes aegypti. The Ifr-silver nanoparticles (AgNPs) were characterized structurally and functionally using UV-visible spectrophotometer followed by scanning electron microscopy (SEM ...

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.

The Planter, 2021
Rugose spiraling whitefly (RSW), Aleurodicus rugioperculatus Martin. is an invasive pest in India. It feeds on most of the green-leaved plants including arecaceae palms. Both the nymphs and adults suck the sap from the leaves causing yield loss. For effective management of the pest, ICAR- Indian Institute of Oil Palm Research, Pedavegi has developed a ...

Biological Control, 2011
Abstract The bioactivity of the entomopathogenic fungus, Isaria fumosorosea , and the plant secondary chemical, 20-Hydroxyecdysone, against Plutella xylostella were tested. 20-Hydroxyecdysone gave an apparent increase in adjusted larval mortality in a dose-dependent manner, whereas no influence of 20-Hydroxyecdysone was observed on conidial ...

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 =

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.

ABSTRACTMythimna separata is a destructive polyphagous pest of field crops. Insecticides are generally applied for its control which not only negatively affect natural enemies and the environment and cause resistance in the insect pests. There is a need for the friendly method which is safe for the environment and life.

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.
