Breeding of entomopathogenic fungi in different substrates

Variability in the production of extracellular enzymes by entomopathogenic fungi grown on different substrates

Entomopathogenic fungi are important controllers of pest-insects populations in agricultural production systems and in natural environment. These fungi have enzymatic machinery which involve since the recognition and adherence of spores in their hosts culminating with infection and death of these insects. The main objective of this study was to analyzed extracellular enzyme production of the fu...

Preliminary study on virulence of some isolates of entomopathogenic fungi in different developmental stages of Boophilus annulatus in Iran

NEW RECORDS OF SOME ENTOMOPATHOGENIC FUNGI FROM IRAN

Examining dead insects from different locations in Mazandaran, Gilan and TehranProvinces, specimens with fungal outgrowth were selected for further investigations. After isolation and purification of fungi they were identified as follows:Beauveria brongniartii (Sacc.) Petch*On Coccinella septempunctata, Tehran Prov., Varamin, Ghara-Aghaj mountains, M.H. Ghassemi (IRAN 1025 C). Paecilomyces tenu...

Entomopathogenic fungi-based mechanisms for improved Fe nutrition in sorghum plants grown on calcareous substrates

Although entomopathogenic fungi (EPF) are best known for their ability to protect crops against insect pests, they may have other beneficial effects on their host plants. These effects, which include promoting plant growth and conferring resistance against abiotic stresses, have been examined in recent years to acquire a better understanding of them. The primary purposes of the present study we...

Entomopathogenic Fungi on Hemiberlesia pitysophila

Hemiberlesia pitysophila Takagi is an extremely harmful exotic insect in forest to Pinus species, including Pinus massoniana. Using both morphological taxonomy and molecular phylogenetics, we identified 15 strains of entomogenous fungi, which belong to 9 genera with high diversities. Surprisingly, we found that five strains that were classified as species of Pestalotiopsis, which has been consi...
