  <dc:description xml:lang="srp">U proleće 1991. godine u hrastovim šumama N.P. &quot;Đerdap&quot; utvrđena je
kulminacija gradacije ranih hrastovih defolijatora u GJ: &quot;Zlatica&quot;, &quot;Boljetinska reka&quot;,
&quot;Boljetin - Pecka hara&quot;, &quot;Kožica&quot; i &quot;Crni vrh&quot; na povrsini od 3.856 ha. Konstatovano
je ukupno 11 vrsta defolijatora iz 5 familija ali su izrazito dominantne u svim
gazdinskim jedinicama bile Geometridae, naročito mali mrazovac (Operophtera brumata
L.).
Kontrolom brojnosti ženki mrazovaca u jesen 1991. godine metodom lepljivih pojaseva
konstatovan je prosečan broj zenki/1 cm obima iznad kritičnog broja u svih 5 gazdinskih
jedinica.</dc:description>
  <dc:description xml:lang="eng">In spring of 1991 , in the oak forests of National park &quot;flerdap&quot;, the
gradation culmination of early oak defoliators was registered in management units
&quot;Zlatica&quot;, &quot;Boljetinska.reka&quot;, &quot;Boljetin-Pecka hara&quot;, &quot;Kozica&quot; and &quot;Crni Vrh&quot;, on the
area covering 3856 ha. The total of 11 defoliator species form five families was noted,
but Geometridae, small winter moth (Operophtera brumata L.) in particular, were
extremely dominant in all the management units.
The average number of females/I cm in volume above the critical number was
registered in all of the five management units during the control of number of female
winter moths in fall 1991, by the adhesive belts method.</dc:description>
