Abstract

Breskvin (Grapholita molesta Busck, 1916.) i šljivin (Grapholita funebrana Treitschke, 1835.) savijač predstavljaju ekonomski značajne tehnološke štetnike iz reda Lepidoptera svrstanih u porodicu Tortricidae. Gusjenica je štetni stadij te pričinjava najveće štete na plodu. Kako bi štete bile manje, potrebno je praćenje savijača feromonskim mamcima, utvrđivanje dinamike ulova štetnika, kritičnog broja i roka suzbijanja. U istraživanju populacije breskvinog savijača na Jazbini korištene su feromonske lovke mađarske tvrtke Csalomon. Lovke, su postavljene, 3. travnja 2017. godine. u voćnjak marelice i istovremeno feromonske lovke za praćenje šljivinog savijača u obližnji voćnjak šljive. Obzirom da feromon za breskvinog savijača privlači i šljivinog savijača radi točne procjene o kojoj se vrsti radi obavljena je sekcija i determinacija vrste prema morfološkim oznakama spolnog organa mužjaka. Tijekom istraživanja ulovljeno je svega 16 savijača na feromonsku lovku za breskvinog savijača od čega su neki bili šljivini savijači. Populacija breskvinog savijača u 2017. godini bila je izrazito niska, što nije zahtijevalo suzbijanje. Bez determinacije ulovljenih savijača nije moguće temeljem praćenja štetnika pomoću feromonske lovke procijeniti populaciju breskvinog savijača.

Abstract (english)

Oriental fruit moth (Grapholita molesta Busck, 1916.) and Plum fruit moth (Grapholita funebrana Treitschke, 1835.) represent economicly significant technological pests from the order Lepidoptera, familly Tortricidae. Larva is the most harmful stage and the most damage is on the fruit. To reduce the damage, it is very important to use pheromone traps. To keep damage at the minimum it is needed to monitor the moth with pheromone traps, and establish the dynamic of the hunted moth, its critycal number and the deadline for supression. In population research of the Oriental fruit moth, pheromone traps from a Hungaryan company, Csalomon, were used. The traps were set up on April 3𝑟𝑑, 2017. in a apricot orchard and simultaneously in a nearby plum orchard. Given that pheromone traps attract both types of fruit moth a morphological examination of the male sex organs were needed to select and determine the type of moth. Throughout the research only 16 moths were captured and some were plum fruit moth. Oriental fruit moth population in 2017. was extremly low and did not demand suppression. Without the determination of the captured moths it is not possible to asses the population oft he Oriental fruit moth using only pheromone traps.
