Gusjenice mnogih leptira predstavljaju značajne štetnike različitih voćnih vrsta. Jedan od opasnijih štetnika je Zlatokraj (Euproctis chrysorrhoea L.) koji u godinama masovne pojave izaziva golobrst voćaka. Na području općine Prozor-Rama (Federacija BiH) u 2013. godini zabilježena su velika oštećenja u nasadima voćaka zbog napada gusjenica Zlatokraja. Osim fiziološkog slabljenja voćaka evidentirana su i odumiranja mladih stabala u nasadima šljiva kao izravna posljedica napada spomenutog štetnika. U slučaju normalne i povišene brojnosti štetnik se može suzbijati dok u godinama prenamnoženja Zlatokraj postaje veliki problem. Da bi se suzbila pojava tog štetnika, primjenjuju se mehaničko-fizičke, kemijske i biološke mjere., The caterpillars of many butterflies represent significant pests of various kinds of fruit. One of the more dangerous pests is Brown-tail moth (Euproctis chrysorrhoea L.) that in the years of mass phenomena causes defoliation of fruit trees. In the municipality Prozor-Rama (Federation of BiH) in 2013, great damages to plantations of fruit trees were observed from attacks by catepillars of Brown-tail moth. Not only physiological weakening, but also dying of young trees in plum plantation were recorded as a direct result of the attack by mentioned pest. In the case of normal and elevated number of pests, it’s possible to suppresse them, but in case of overpropagation it becomes a big problem. In order to combat it, the mechanical-physical, chemical and biological measures are available.
