Abstract

Šljivin savijač (Grapholita funebrana (Treitschke, 1835)) tehnološki je štetnik šljive. Oštećuje plod, što na posljetku dovodi do opadanja te smanjenje prinosa. Početak leta i jačina populacije šljivinog savijača na fakultetskom pokušalištu Jazbina praćena je postavljanjem feromonske lovke u voćnjak šljive tijekom tri vegetacijske sezone. Potreba i rokovi suzbijanja prikazani su na temelju srednjih dnevnih temperatura, odnosno računanjem sume efektivnih temperatura u navedenom razdoblju. Utvrđena je različita populacija štetnika unutar tri vegetacijske sezone. Šljivin savijač lovio se iznad kritičnog broja u sve tri promatrane vegetacijske sezone što iziskuje potrebu za suzbijanjem štetnika.

Abstract (english)

Plum fruit moth (Grapholita funebrana (Treitschke, 1835)) is tehnological plum pest. It damages the fruit which leads to decrease and reduction in yield. The beginning of flight and population growth of plum fruit moth on Faculty experiment field called "Jazbina" is followed by setting pheromone traps in plum orchard during three vegetational season. The necessity and repression deadlines are based on average daily temperatures, in references to calculating the sum of effective temperatures in said time period. During three vegetational seasons we managed to determine different pest populations of plum fruit moth. Plum fruit moth has been cought above critical number in all of the three opserved vegetational seasons, which increases the need to pest repression.
