o:6654 KRETANJE BROJNOSTI HRASTOVIH DEFOLIJATORA U ŠUMAMA NA PODRUČJU BEOGRADA sr Populaciona gustina hrastovih defolijatora utvrđivana je u stadijumu jaja (gubar ), gusenice (gubar, hrastovi savijači mrazovci) i leptira (mrazovci). Kulminacija gradacije gubara konstatovana je 1986. godina na Avali i Trešnji (suzbijanje izvedeno skidanjem i spaljivanjem legala), 1988. u GJ "Gibavac" (suzbijanje izvedeno aviozamagljivanjem 220 ha preparatom Decis EC-2,5) i 1991. godine na Avali, Trešnji i Lipovici (suzbijanje izvedeno natapanjem legala petroleumom).Aviosuzbijanje hrastovih savijača izvedeno je 1989. godine u GJ "Bojčinska suma" na 500 ha, GJ "Crni lug" na 600 ha i GJ "Avala" na 300 ha, takođe preparatom Decis. Uspeh tretiranja na svim površinama bio je veoma dobar. Populational density of oak defoliators was being researched in egg stage (gypsy moth), caterpillar stage (gypsy moth, green oak tortrix moths and winter moths), and in butterfly stage (winter moths). Gradation culmination of gypsy moth was . registered on Avala and Trešnja in 1986 (warding off done by removing and burning of eggs hatches), in forestry complex "Gibavac" (warding off performed on 220 ha by air-hazing with Dec is EC-2,5 preparation), and on A v a l a, Trešnja and Lipovica in 1991 (warding off done by soaking the egg hatches in paraffin oil). In 1989, warding off from air was performed in management units "Bojčinska šuma" on 500 ha area, "Crni lug" on 600 ha area and "Avala" on 300 ha area, also with Dec is preparation. Treatment proved to be very successful on all the areas. gubar, hrastovi savijači, mrazovci, jajna legla, gusenice, Decis EC-2,5 gypsy moth, green oak tortrix moths, winter moths, egg hatches, caterpillars, Decis EC-2,5 1552101 0351-9147 2024-12-17T12:25:01.851Z 44 yes 46 Danica Minić 46 Radovan Marović 46 Julijana Pavlović application/pdf 5054945 https://unilib.phaidrabg.rs/o:6654 no yes 1 70 92000001 1995 71A07 Zbornik radova Instituta za šumarstvo 119 130 Institut za šumarstvo 1995
