Entomopathogenic fungi of Eurygaster integriceps Puton (Hemiptera: Scutelleridae): collection and characterization for development. Biological Control, 27 (3), pp. 260-272.en_US
dc.description.abstractExploratory activities were done in Syria, Turkey, Iran, Uzbekistan, Kazakhstan, The Kyrghyz Republic, and Russia to locate entomopathogenic fungi of Eurygaster integriceps. Isolates from the entomopathogenic genera Beauveria, Paecilomyces, and Verticillium were collected. Beauveria bassiana was the most commonly recovered species. Thirty-one isolates of the 221 recovered were examined at 20, 25, 30, and 35 °C for 20 days for growth and sporulation. Growth and sporulation were generally highest at 25 °C. None of the isolates grew at 35 °C, and at 30 °C growth was retarded with no conidia being produced. Single- and multiple-concentration bioassays were conducted on greenhouse-grown wheat plants and in pine litter to evaluate virulence of fungi from several sources to E. integriceps. When tested at a single concentration, mortality after 15 days ranged from 66 to >95% in the litter assays and 50 to 91% in the plant assays. There was a distinct concentration response for most of the isolates tested in the multiple-concentration assay, particularly in the in-litter environment. In litter, mortality tended to develop earlier than in on-plant assays. Several isolates of B. bassiana and one Metarhizium anisopliae displayed consistently high virulence against E. integriceps and were more virulent than two commercial strains. Our results demonstrate the potential of entomopathogenic fungi for management of E. integriceps in overwintering sites and in wheat fields.en_US
