Spremljanje sezonske dinamike vrbarja (Cossus cossus L.) v ekstenzivnih sadovnjakih s feromonskimi vabami : diplomsko delo - visokošolski strokovni študij = Seasonal dynamics of goat moth (Cossus cossus L.) in extensive orchards using pheromone traps : graduation thesis - higher professional studiesJeršič, PeterV letih 2005 in 2006 smo v nasadu marelic in češenj v bližini Pišec s feromonskimi vabami spremljali gostoto populacije samcev vrbarja (Cossus cossus L.), katerega gosenice so na omenjenem območju v ... preteklosti povzročale propadanje dreves. Škodljivec se je v teh letih masovno pojavljal od konca junija do konca julija. Ker za zatiranje škodljivca v Sloveniji ni registriranega insekticida, je treba iskati druge možnosti za zmanjševanje škodljivosti te žuželčje vrste. Med najbolj obetavne tovrstne metode štejemo uporabo sintetičnih feromonov v obliki dispenzorjev (metoda motenja parjenja),ki jo predlagamo za implementacijo v sisteme pridelave sadja na območjih, kjer predstavlja vrbar pomemben biotični dejavnik omejevanja gospodarnosti pridelave. V letu 2005 smo največ samcev (1 metulj/vabo/2 dni) ugotovili v 1. dekadi julija, ko je vsota efektivne temperature znašala 595,4 °C, povprečna temperatura zraka pa 18,8 °C. V letu 2006 smo največ metuljev (1,4 samcev/vabo/dan) v vabah našli v drugi polovici zadnje dekade junija, pri vsoti efektivne temperature 519,0 °C, takrat, ko je povprečna temperatura zraka znašala 24,6 °C. Kot spodnji hipotetični prag aktivnosti smo uporabili 10,0 °C.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [P.
