An evaluation of some entomopathogenic fungi for green peach aphid (Myzus persicae [Sulzer]), (homoptera: Aphididae) under laboratory conditons

This study was carried out between 2014 and 2017 in Erzincan province Turkey. Our aim was to test pathogenesis of soil isolated entomopathogenic fungi from Erzincan and the Myzus persicae (Sulzer), (Homoptera: Aphididae). A total of 78 entomopathogenic fungi isolates including 63 Beauveria bassiana and 15 Metarhizium anisopliae were obtained. Our study was followed by incubation for 12 days and the first cases were seen on the third day. It was recorded that B. bassiana isolates caused the highest mortality rate on the 3rd day (BbEMRKZ2a, 10.50%); 5th day (BbEMRKZ5b and BbEÜ3, 22.39%); 7th day (MaEM3i, 45.71); 9th day (BbEMRKZ1a and BbER4, 50.00%), and after 12 days (BbEİ5, 62.54%). Also, it was recorded that M. anisopliae isolates caused the highest mortality rate on the 3rd day (MaEMR1a, 5.78%), 5th day (MaET3, 23.32%), 7th day (BbER4, 37.4%), 9th day (MaEİ3 50.84%), and after 12 days (MaET3, 60.01%). In the control group, the highest mortality rate was 1.12% at the end of the incubation period. © 2021, ALÖKI Kft., Budapest, Hungary.
