Abstract
Cydalima perspectalis, which is a kind of alien invader, is one of the most important pests of the boxwood plant for Turkey. This study was carried out to investigate the control methods of C. perspectalis. Five bacteria samples were studied which are Brevibacillus brevis, Bacillus thuringiensis subsp. kenyae, Bacillus thuringiensis subsp. kurstakii, Bentar®, Bacillus subtilis and Neemazal® organic insecticide were used as positive control. As a result of the treatments, the most effective entomopathogen was determined as Bacillus subtilis with a rate of 82.5% and the least effective entomopathogen as Bacillus thuringiensis subsp. kenyae with 65%. It is concluded that Bacillus subtilis entomopathogen can also be used within the scope of the integrated management to prevent the spread and damage of C. perspectalis in the region where it is detected.
