Abstract:V raziskovalnem delu smo ugotavljali pestrost opraševalcev na jagodah (Fragaria × ananassa Duch.) ter pomen medonosne čebele in divjih opraševalcev pri opraševanju jagod. Popis opraševalcev je potekal v nasadu jagod, pokritem s plastično folijo, leta 2018 v kraju Zrkovci v bližini Maribora. Poleg ugotavljanja pestrosti smo merili tudi hitrost opraševanja, ki se nanaša na število cvetov, ki jih opraševalec obišče v času 30 sekund. Rezultati raziskovanja so pokazali, da je najpogostejši opraševalec jagode medonosna čebela. Preostali opraševalci (čmrlji, muhe trepetavke, dvokrilci in drugi opraševalci) so bili zastopani v manjših deležih. Dejavnost opraševalcev se je preko dneva pri posameznih skupinah opraševalcev razlikovala; medonosna čebela je bila najbolj aktivna v osrednjem delu dneva, aktivnost čmrljev je bila največja pozno dopoldan in pozno popoldan, dvokrilci pa so bili najbolj aktivni v jutranjih urah. Vreme je vplivalo na število in dejavnost opraševalcev ter hitrost opraševanja. Oddaljenost od roba rastlinjaka, opazovalni dan ter ura opazovanja so imeli vpliv na število in dejavnost določenih opraševalcev. Večji delež čebel je bil v sredinskih oziroma osrednjih rastlinjakih (tunelih), večji delež muh trepetavk, dvokrilcev in drugih opraševalcev pa v robnih rastlinjakih.

Title:Foraging Activities of Strawberry (Fragaria × ananassa Duch.) Pollinators
Abstract:In the research the diversity of pollinators on strawberries (Fragaria × pineapple Duch.) and the importance of honey bees and wild pollinators in the pollination of berries were determined. The list of pollinators was conducted in a strawberry plantation covered with plastic wrap in 2018 in Zrkovci, near Maribor. Besides determining the diversity, the speed of pollination, which refers to the number of blossoms visited by one pollinator at a time of 30 seconds were also measured. The results indicate that the most common strawberry pollinator is the honey bee. Other pollinators (bumblebees, fly flies, bipeds and other pollinators) were represented in smaller proportions. The activeness of pollinator varied across groups; the honey bee was the most active in the central part of the day, bumblebee activeness was highest in the late morning and late afternoon, bipeds were most active in the morning. The weather affected the number of pollinators, pollinator activity and pollination speed. The distance from the edge of the greenhouse, the observation day, and the hour of observation had an impact on the number and activeness of certain pollinators. The greater proportion of bees was in the center or in central greenhouses (tunnels), and the greater proportion of fly flies, bipeds and other pollinators in the marginal greenhouses.
