According to the investigations conducted in the Yerevan parks and public gardens, the growth and development of the fragrant tree species are retarded due to the life activity of Obolodiplosis robiniae (black locust gall midge), Euura tibialis (sawflies) and Halyomorpha halys (brown marmorated stink bug); they also lose their decorative appearance. Besides, favorable conditions are created for the development of other pests.The results of trials have indicated that the mentioned strains of BT microbiological preparation are rather effective, and hence can be applied in the planned and integrated struggle against E. tibialis, O. robiniae and H. halys.
