formulation of blastospores of entomopathogenic fungi may help to overcome unfavorable climatic conditions and may increase their effectiveness. in the present study, different products of wettable powder of blastospores were prepared for two isolates of beauveria bassiana and were stored at two different temperature regimes, refrigerator (4±1°c) and laboratory (24±3°c) conditions. after storag...

the entomopathogenic fungus, beauveria bassiana (bals.) vuill., is one of the facultative insect pathogens with a significant host range and host specificity. conidial survival may be affected by either environmental factors or by bio-pesticides and chemical products used to protect crop plants. in this research, compatibility of the above mentioned fungus was studied with some traditional inse...

Injury to olive tree trunks and branches because of biotic and abiotic factors, such as pruning and mechanical harvesting, attracts the olive pyralid moth Euzophera pinguis Haworth (Lepidoptera: Pyralidae). This moth has become increasingly important in the Mediterranean region during recent years. The use of an entomopathogenic fungus for wound dressing for pest control is reported for the fir...

The biocontrol potential of entomopathogenic fungi against arthropod pests depends on not only their virulence to target pests but tolerance to outdoor high temperature and solar UV irradiation. Two Beauveria bassiana superoxide dismutases (SODs), BbSod2 and BbSod3, were characterized as cytosolic and mitochondrial manganese-cored isoenzymes (MnSODs) dominating the total SOD activity of the fun...

Fungal virulence is multifaceted and dependent on multiple factors including the pH of spore suspension. In this study, we accessed effects six values Beauveria bassiana, Metarhizium anisopliae medium for growth, sporulation, mortality sugarcane stalk borer Diatraea saccharalis. The culture fungi was performed onplates containing PDA (Potato Dextrose Agar) medium. Virulence tested in D. sacchar...

The phylogenetic lineage, taxonomic affiliation and interrelationships of important asexual entomopathogenic fungal genera were studied using the sequences of partial regions of beta-tubulin and rRNA genes. The species structures of Beauveria bassiana and Nomuraea rileyi were also investigated. A total of 147 fungal entries covering 94 species were analysed. Phylogenetic analysis placed all the...

The microbiota present in Stomoxys calcitrans larvae may assist their survival in contaminated environments through production of inhibitory substances. Bacteriological identification methods, the polymerase chain reaction (PCR) and scanning electron microscopy (SEM) were used to detect a bacterium naturally present in mucus and macerated S. calcitrans larvae. The antifungal activity was determ...

The principal objective of this study was to determine the optimal liquid culture conditions in shake flasks for maximal sporulation of Beauveria bassiana. The optimal initial pH for the spore production of B. bassiana using Potato Dextrose Broth was 5.2. The screening in shake flasks of carbon and nitrogen sources resulted in the identification of an optimal medium based on 3% sucrose and 1% c...

The most important pathogenic fungus of the silkworm, Bombyx mori L. (Lepidoptera: Bombycidae), is Beauveria bassiana (Balsamo-Crivelli ) Vuillemin (Hypocreales: Clavicipitaceae), which causes significant damage to sericulture production. Therefore, diagnosing fungal disease and developing new control measures are crucial to silk production. To better understand the responsive and interactive m...
