Abstract

Najznačajniji štetnici u uzgoju jabuke pripadaju redu Lepidoptera. Po štetnosti se posebno ističu savijači plodova te pupa i lista (Tortricidae) koji napadaju generativne organe. No, u uzgoju se redovito pojavljuju i staklokrilci (Sesiidae) koji napadaju vegetativne organe. Iz navedenih porodica u najvažnije štetnike pripadaju jabukov savijač, sivi savijač pupova i jabukova staklokrilka. U radu su populacije navedenih štetnika praćene lovkama na bazi seksualnih atraktanata koje privlače mužjake, kao i lovkom na bazi hranidbenog atraktanta koji privlači oba spola. Cilj istraživanja bio je utvrditi učinkovitost lovke na bazi hranidbenog atraktanta u privlačenju ekonomskih štetnika jabuke, te usporediti njezinu učinkovitost u odnosu na feromonske atraktante. U provedenom istraživanju učinkovitost hranidbene lovke u ulovu jabukova savijača iznosila je manje od 1% od ukupnog ulova na feromonsku lovku, dok je u ulovu sivog savijača pupova iznosila 86 % od ukupnog ulova na feromonsku lovku, a u ulovu jabukove staklokrilke iznosila je 6 % od ukupnog ulova na feromonsku lovku. Seksualni atraktanti pokazali su se učinkovitijim u privlačenju jabukova savijača i jabukove staklokrilke, dok je u ulovu sivog savijača pupova hranidbeni atraktanat pokazao vrlo dobru učinkovitost u procjeni populacije štetnika.

Abstract (english)

The most important pests in apple growing belong to the order of butterflies (Lepidoptera). In terms of damage, the Tortrix moths, which attack the generative organs, are the most important. However, clearwing moths (Sesiidae) also regularly occur in cultivation and attack vegetative organs. Of the above families, the most important pests are codling moth, green budworm, and hornet clearwing moth. Populations of these pests were monitored using traps based on sex attractants (pheromones) that attract males and traps based on feeding attractants that attract both males and females. The aim of the study was to determine the effectiveness of a bait based on a feeding attractant in attracting economic pests of apples and to compare its effectiveness with that of sex attractants. In the studies conducted, the effectiveness of the feeding attractant in catching codling moth was less than 1% of the total catch with the pheromone trap, while in catching green budworm it was 86% of the total catch with the pheromone trap and in catching hornet clearwing moth it was 6% of the total catch with the pheromone trap. Sex attractants were found to be more effective in attracting codling moth and hornet clearwing moth, while in catching green budworm, feeding attractant showed very good effectiveness in assessing pest population.
