- Abstract
Aims: Capnodis tenebrionis (Linnaeus, 1758) (Coleoptera: Buprestidae) which is known as Mediterranean flatheaded peachborer, is an important pest of stone fruit trees in Turkey as well as Mediterranean countries. In this study, pathogenicity of entomopathogenic fungi isolated from C. tenebrionis was investigated according to life stages. Methods and Results: Fungal isolations were made from adults of C. tenebrionis collected from the cherry orchards of Tekirdağ province and they were identified morphologically and molecularly. Three entomopathogenic fungi, two of which were first time isolated from C. tenebrionis were identified as Baeuveria bassiana (Balsamo) Vuillemin, 1912; Fusarium acuminatum Ellis & Everhart, 1916 and Lecanicillium fungicola Zare & W. Gams, 2008. Pathogenicity studies with the isolates obtained were carried out on eggs, first instar larvae and adults of C. tenebrionis under 26±1 °C temperature, 50±5% humidity and 16:8 (A:N) long daylight conditions. In the pathogenicity tests, the highest mortality rate (81.25±2.26%) and effect value (64.63±1.71%) were obtained from the on C. tenebrionis eggs inoculated by the F. acuminatum isolate. Larvae were fed on two different foods (artificial and natural). While the mortality rate was 71.5±1.32% on the larvae treated with B. bassiana on the semisynthetic diet, the mortality rate reached 100% in the larvae fed on the branch culture. B. bassiana (92.5±1.63%) isolate showed the highest effect in adults. Conclusions: The results obtained showed that biological control by local entomopathogenic fungi could be the first steps in the fight against C. tenebrionis. Significance and Impact of the Study: Due to the fact that the biological stages of C. tenebrionis pass within the tissue and the morphological structure of the adults, the current methods used in the control of the pest are not sufficiently effective. Considering the effect of entomopathogenic fungus isolates obtained in the study, it is thought that it may be possible to develop alternative methods for pest control.
