Vertical migrations of larvae of the gypsy moth (Ocneria dispar L.) and the effects on the activity of natural enemies in the conditions of the south of the Ukraine

, : Vertical migrations of larvae of the gypsy moth (Ocneria dispar L.) and the effects on the activity of natural enemies in the conditions of the south of the Ukraine. Ekologo morfologicheskie osobennosti zhivotnykh i sreda ikh obitaniya: recd 1985; 102-104

Studies were carried out in the Kherson, Nikolaev and Odessa regions of the Ukrainian SSR, USSR, in 1970 and 1972 on the vertical migration of larvae of the forest pest Ocneria dispar and its effect on the activity of natural enemies of the pest.
