Conidial Germination of Two Biotypes of Nomuraea rileyi

The Florida Entomologist, 1991
The entomopathogenic fungus Nomuraea rileyi has a worldwide distribution and has been reported from many different insects (Ignoffo 1981). Although geographical isolates of N. rileyi from different insects have very similar isozyme patterns (Boucias and Ignoffo unpub.), they exhibit widely different host spectra (Ignoffo 1981, Boucias et al.

Myco‐Biocontrol of Insect Pests: Factors Involved, Mechanism, and Regulation

Journal of Pathogens, Volume 2012, Issue 1, 2012., 2012
The growing demand for reducing chemical inputs in agriculture and increased resistance to insecticides have provided great impetus to the development of alternative forms of insect‐pest control. Myco‐biocontrol offers an attractive alternative to the use of chemical pesticides.

LC50 of the Peptide Produced by the Entomopathogenic Fungus Nomuraea rileyi (Farlow) Samson Active Against Third Instar Larvae of Anticarsia gemmatalis (Lep.: Noctuidae)

Brazilian Archives of Biology and Technology, 2002
The entomopathogenic fungus Nomuraea rileyi (Farlow) Samson produced a peptide active against Anticarsia gemmatalis 3rd instar larvae. To produce this peptide, N. rileyi was cultivated aerobically in Saboraud, maltose, yeast-extract broth at 26 ± 1ºC for

Fungal Ecdysteroid-22-oxidase, a New Tool for Manipulating Ecdysteroid Signaling and Insect Development [PDF]

, 2012
Steroid hormones ecdysteroids regulate varieties of developmental processes in insects. Although the ecdysteroid titer can be increased experimentally with ease, its artificial reduction, although desirable, is very difficult to achieve.

Lipid composition of the entomopathogenic fungus Nomuraea rileyi

Journal of Invertebrate Pathology, 1984
Abstract The total lipid content, neutral and polar lipid composition, and fatty acid profiles were determined for the different developmental stages of the entomopathogenic fungus, Nomuraea rileyi . In general, the lipid composition of N. rileyi was found to be very similar to that of other Fungi Imperfecti. Triacylglycerides and sterols were the
