Potential of Turkish Beauveria bassiana isolates for the management of the polyphagous planthopper, Orosanga japonica Melichar 1898 (Hemiptera: Ricaniidae)

İsmail ERPER

Background Entomopathogenic fungi are a potential biological control agent for many pests. In this study, 14 native Beauveria bassiana isolates were molecularly identified and assessed for their virulence and mortality against adults of the polyphagous planthopper Orosanga japonica, Melichar (Hemiptera: Ricaniidae) a polyphagous sap-feeding insect, under laboratory conditions. Results Isolates obtained from naturally infected adults O. japonica were molecularly identified as B. bassiana by sequencing the internal transcribed spacer and 26S large subunit of ribosomal DNA. In the bioassay, the r ...More

Efficacy of the entomopathogenic fungi; Beauveria bassiana and Metarhizium anisopliae against the cowpea weevil, Callosobruchus maculatus F. (Coleoptera: Chrysomelidae: Bruchinae)

İsmail ERPER

The efficacy of the two entomopathogenic fungi, Metarhizium anisopliae (TR 106) and Beauveria bassiana (TR 217), was tested against the adults of the cowpea weevil, Callosobruchus maculatus F. (Coleoptera: Chrysomelidae: Bruchinae) in laboratory. Two concentrations of conidial suspensions (1 x 10(6) and 1 x 10(8) conidia/ml) of M. anisopliae and B. bassiana isolates were directly applied on four pairs of adult beetles in Petri dishes (2 ml/dish) and then incubated at two different climatic regimes; 22 +/- 1 degrees C and 26 +/- 1 degrees C with 70 +/- 5% RH, 16:8 h light-to-dark. Lethal time v ...More
