In the forested lands of Georgia Qazbegi National Park, some kinds of insects have been significantly harming the leaved kinds of trees by increasing their population. The most harmful species the 64 hectare area of the national park where leaved forest trees settle have been identified as Biston betularius, Tortrix viridana, Alsophila aescularia, Erannis defoliaria, Leucoma salicis and by using Microbial struggle method, Bacillus thuringiensis Berliner var. kurstaki bacteria has been implemented against them. After 3 days of laboratory tests, the exposure percentages of nymphs have been identified as follows: B.betularius 85%, T.viridana 88%, A.aescularia 84%, E.defoliaria 87% and L.salicis 90%, all nymphs have been identified as 86.8% in average. During field implementation, a great majority of insects has been found to die within the first 12 hours, and the rest of them to die within 2-3 days.
