Pathogenicity of entomopathogenic fungi, Beauveria bassiana and Metarhizium anisopliae var. anisopliae (Deuteromycotina: Hyphomycetes) against Eurygaster integriceps (Heteroptera: Scutelleridae)
Entomologia Generalis 30 (1), 63-69
Abstract: The pathogenicity of 4 fungal isolates of Beauveria bassiana (Balsamo) Vuillemin 1912 and 1 isolate of Metarhizium anisopliae var anisopliae (Metschnikoff 1879) Sorokin 1883 to adult sunn bug, Eurygaster integriceps Puton 1881 was tested under laboratory conditions. One isolate (Bb-1) originated from E. integriceps (Tekirdag, Turkey), other isolates (5665, 1394 and 6444, respectively) originated from ARSEF collections, Eurygaster Laporte 1832 sp. (Turkey), Lygus Hahn 1833 sp. (France), Locusta migratoria Linnaeus 1758 (patented, commercialized strain) and one isolate (3540) M. anisopliae from Galleria mellonella (Linnaeus 1758) (USA). A single exposure concentration (1x10⁶ conidia/ml) assay for each isolate was used by immersing the adults in 10 ml of a fungal suspension for 5 s. Mortality ranged from 40.0 to 82.5% in B bassiana, while the mortality was 100.0% in M. anisopliae at 8 days after treatment. The test isolates caused a significantly different mortality compared to the untreated control at 12 days post-application. When the data of mortality was corrected by Abbott formula, the obtained isolate, Bb-1 had significantly lower effect than those of the ARSEF fungal isolates and anisopliae was most virulent fungus to E. integriceps adults.
