Carotane-type sesquiterpenes from cultures of the insect pathogenic fungus Isaria fumosorosea
Journal of Asian Natural Products Research, 2017Two new carotane-type sesquiterpenes named trichocaranes E (1) and F (2), along with two known ones CAF-603 (3) and trichocarane C (4), were isolated from cultures of the insect pathogenic fungus Isaria fumosorosea. Their structures and relative configurations were elucidated by extensive spectroscopic analysis and X-ray crystallography.

Culture medium improvement for Isaria fumosorosea submerged conidia production
Biochemical Engineering Journal, 2009Abstract Submerged conidia and blastospores of the entomopathogenic fungus Isaria fumosorosea are produced in several liquid culture media. However, yields and the ecological fitness of these propagules vary according to culture media composition. In most culture media, hyphae, blastospores and submerged conidia are white but we found that in some ...

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 ...

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.

Biosafety of an entomopathogenic fungusIsaria fumosoroseain an acute dermal test in rabbits
Cutaneous and Ocular Toxicology, 2016Isaria fumosorosea (formerly Paecilomyces fumosoroseus) is an entomopathogenic fungus that has been proposed as a low risk environmental alternative to the use of chemical insecticides to control agricultural pests and disease vectors. Although there are some mycoinsecticides already being marketed in many countries, not all their biosafety protocols ...

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-

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.

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 ...

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.
