GODINI APPERANCE, MOVEMENT AND CONTROL OF DISEASE CAUSERS AND HARMFUL INSECTS ON FOREST PLANTS IN THE AREA OF SERBIA (WITHOUT AUTONOMOUS REGIONS) IN 1979. sr Among economically noxious diseases the greatest attention deserves the Fomes annosus (Fr. Cooke) and the Dothichiza populea Sacc. et Br. The economic importance represents also the rest of the micropopulation among which the most significant are the following species: Fusarium spp., Gnomonia veneta, Armillaria mellea, Ungulina (Fames) fomentaria, Guignardia aesculi, Microsphaera alphitoides and other. Of insects species which have been found on examined objects deserves the attention the population density of wooly plant louses (Pineus strobi, Adeleges laricis) on Pinus strobus, Larix europeus and Pseudotsuga douglasii, then Chermes spp. on Picea excelsa beech borer, ( Agrilus viridis) on Fugus silvatica, white pine weevel (Pissodes notatus), european pine schoot moth (Rhyacionia buoliana) on young trees of Pinus nigra as well as the complex of forest tree defoliators (fam. Tortricidae, Noctuidae, Geometridae). The other species which have been found were under the threshold of tolerance. 2025-04-01T06:28:02.545Z 44 yes 46 Milka Peno 46 Milomir Vasić application/pdf 3888870 https://unilib.phaidrabg.rs/o:7351 no yes 1 70 92000001 1979 71A07 Zbornik radova Instituta za šumarstvo 15 65 75 Institut za šumarstvo 1979
