EFFECTS OF SOME BIOINSECTICIDES ON MACROSIPHUM ROSAE (L.) AND MYZUS PERSICAE (SULZER) (HEMIPTERA: APHIDIDAE)

In this study, biological activities of bioinsecticides which has three different entomopathogenic fungi (Nostalgist BL (R)-Beauveria bassiana; Nibortem (R)-Verticillium lecanii and Met 52 (R) Metarhizium anisopliae) against Macrosiphum rosae L. and Myzus persicae (Sulzer) (Hemiptera: Aphididae) were examined under laboratory conditions. Therefore, bioinsecticides were applied to the second stage nymphs of both aphids by spraying method as the commercially recommended rate. Petri trials were conducted based on randomized parcel trial patterns with 5 replicates. After the applications completed, results were evaluated by counting on live individuals at the 1st, 3rd, 5th and 7th days. The overall results of the study determined that bioinsecticides infect both aphids. While the effects of bioinsecticides on M. rosae were determined as 100.00% on the 5th day of counting for Met 52 (R) and Nostalgist BL (R) and all bioinsecticides on the 7th day of counting of the applications. The highest mortality rates of the bioinsecticides application on M. persicae were recorded in the Nostalgist BL (R), with 23.00%, 70.00%, 82.00% and 91.00%, respectively. As a result, it was found that the Nostalgist BL (R) was an effective microbial control agent on the second stage nymphs of both M. rosae and M. persicae.
