Virulence of Some Entomopathogenic Fungi Against Adult of Blossom Beetle, Epicometis hirta (Poda) (Coleoptera: Scarabaeidae)

The Blossom Beetle Epicometis hirta (Poda) (Coleoptera: Scarabaeidae) is one ofthe important pest that limits apple production.. This study was aimed to examine the role of twoentomopathogenic fungi (Beauveria bassiana and Fusarium sp.) were isolated from field soil fromAdana province. E. hirta collected from Yozgat, Sorgun, Gedikhasanlı province and the districts andthe entomopathogenic fungi inoculated on E. hirta adults by spraying method. In the experiment, 1x106,1x107 and 1x108 conidia ml-1 concentrations were used. 40 adults per concentration and 10 adults perrecurrence were used within four recurrences. After the inoculation, mortality rates mycosis rate andwere calculated for day 7 and 14 days. At 7th day, the mortality rates of B. bassiana were calculated as,60%, 85%, 80% and for Fusarium sp. isolates were calculated as; 40%, 35%, 40% respectively. At 14thday, the mortality rates of B. bassiana were calculated as 70%, 90%, 90% and for Fusarium sp. isolates;50%, 70%, 75% respectively. LC50 values were determined using Fusarium sp. (213) and B. bassiana(310) isolates were 251.83x105 and 101.94x105 conidia mature-1, respectively. The results of the studyB. bassiana isolates (1x107 and 1x108 conidia ml-1 doses) could be used as potential biological controlagents in classical biological control programs aimed at managing the pest.
