| Özet |
| The sycamore lace bug, Corythucha ciliata (Say) (Hemiptera: Tingidae), is one of the most destructive pests of plane trees (Platanus spp.) worldwide. This pest is a major nuisance in Europe since plane trees are very popular in parks. Thirteen entomopathogenic fungal strains including 4 isolates of Beauveria bassiana, 2 isolates of Beauveria pseudobassiana, 6 isolates of Metarhizium anisopliae, and 1 isolate of Isaria fumosorosea were screened against adults and nymphs of C. ciliata under controlled laboratory conditions in order to test their efficacy and search for an effective and safe biocontrol agent strategy. Each isolate was applied with a conidial concentration of 1 × 107 conidia mL 1 to adults and nymphs of the pest. B. bassiana isolate KTU24 showed the highest mortality for both adults and nymphs with 86% within 2 weeks after inoculation. This isolate also caused the highest mycosis for adults and nymphs with 83% and 80%, respectively. Mortalities of the other fungal isolates ranged from 43% to 86% and from 36% to 73% for adults and nymphs. Therefore, B. bassiana KTU24 was selected for further dose mortality tests based on its high virulence and mycosis value. Doseresponse mortality bioassays using 5 different concentrations (1 × 104, 1 × 105, 1 × 106, 1 × 107, and 1 × 108 conidia mL 1) were performed to determine the lethal concentration (LC50) of this isolate. Based on probit analysis, the LC50 values of isolate B. bassiana KTU24 were calculated as 5.51 × 105 and 3.96 × 105 conidia mL 1 against adults and nymphs, respectively. Consequently, B. bassiana KTU24 appears to be a promising candidate for further investigations as a biocontrol agent against C. ciliata. |
