         The fall webworm, Hyphantria cunea Drury (Lepidoptera: Arctiidae) has been damaging more than 600 species plants: forest, shade and fruit trees. The American white moth has been included in the European Union Plant Protection Organization quarantine list. At present the pest is widely spread in Western Georgia, including the Black Sea basin of Adjara. In Georgia-Batumi, the fall webwormcauses damage to approximately 100 species of deciduous trees. It feeds on almost all fruit, shade, and ornamental trees except conifers, commonly attacking hickory, walnut, birch, cherry, grape, apple, prunus and crabapple. Larvae constructs silken tents at the top of individual plants. Foliage is webbed together to form a nest that the larvae feed,defecate and pupate in. Nests may cause some branch deformity in years following infestation but otherwise cause little permanent damage. Nests are very unsightly in orchard and ornamental plantings.The use of environmentally safe means is significant for plant protection from pest insects. The pest mainly inhabits populated areas, parks and underwood belt, in places of mass resort. Various control methods have been deployed against the pest H.cunea We made chemical control with the organic insecticidae. NeemAzal-T/S in Batumi in 2007. We used hose-end sprayers and commercial high-pressure sprayers for reaching upper portions of tall trees. The present study has shown that NeemAzal-T/S has got positive effect for control of H.cunea. That the feding activity of larvae in the treated stands has decreased rapidly. In conclusion, this study has revealed that NeemAzal-T/S has preventive nutrition and growth inhibition properties against H.cunea.
