Abstract

Šljivine osice Hoplocampa flava L. žuta šljivina osica i Hoplocampa minuta Christ., crna šljivina osica ubrajaju se u najvažnije štetnike šljive koji utječu na rod i kvalitetu ploda šljive. Izlijetanje osica iz tla u kojemu su prezimile u obliku kukuljice odvija se u proljeće nakon određene sume temperatura potrebnih za razvoj. Vrijeme pojave osica podudara se s fenologijom cvatnje najzastupljenije sorte šljive Bistrice. Noviji sortiment šljive koji je danas prisutan u voćnjacima može izbjeći napad šljivinih osica ako cvatnja nije u skladu s pojavom osica. Važno je pratiti fenologiju šljive, pojavu šljivinih osica i dinamiku leta šljivinih osica te na temelju tih podataka donositi odluke o zaštiti, odnosno o suzbijanju. Praćenje šljivinih osica odvijalo se u voćnjaku šljive na fakultetskom pokušalištu Jazbina u tri vegetacijske sezone na sortama Toptaste, Topfirst, Jojo, Haganta i Elena. Štetnici su praćeni vizualnim atraktantima odnosno bijelim ljepljivim pločama. Rezultati istraživanja su pokazali da se žuta šljivina osica lovila u sve tri godine istraživanja u kritičnom broju, dok je ulov crne šljivine osice izostao 2014. godine. Sorta šljive Elena, Jojo i Haganta zbog kasnije cvatnje izbjegle su napad šljivinih osica.

Abstract (english)

Plum sawfly called Hoplocampa flava L.-yellow plum sawfly and Hoplocampa minuta Christ. - black plum sawfly are known as the most important plum pests which significante affect the gender and quality of the plum fruit. In the Spring after the temperatures reach the level needed for theit growth the sawflies are coming out from the soil where they have spent cold winter time as a form of pupa libera. The time of the sawlies appearance coincides with the flowering phenology of the most common plum sort Bistrica. Newer varietie of the plum which is present in nowdays orchards is capable of avoiding the plum sawfly attack if the flowering is not accordant to the sawflies appearance. It is important to monitor the plum phenology, plum sawflies appearance and their flight dynamic and based by that data to make decisions about protection and suppression. The plum sawflies monitoring took its place on Faculty orchard Jazbina during three vegetation seasons on sorts Totpaste, Topfirst, Jojo, Haganta and Elena. The sawflies were monitored with visual attractive, white sticky boards. The research results showed that yellow plum sawfly was catched in all three years of the research in the critical number while the catch of the black plum sawfly was absent in 2014.The plum sorts Elena, Jojo and Haganta avoided the sawflies attack of the research due to they later flowering.
