Abstract

Na području g. j. ''Borovača'', UŠP Split, u svrhu prikupljanja podataka koji mogu poslužiti za prevenciju i smanjenje šteta koje nastaju masovnom pojavom borovih potkornjaka, provedeno je tromjesečno istraživanje pomoću naletno barijernih feromonskih klopki WitaPrall®. Na dvije pokusne plohe postavljene su po dvije feromonske klopke od kojih je jedna bila ''mokrog'', a druga ''suhog'' tipa. Sakupljanja su se obavljala jednom mjesečno, a rezultati koji su dobiveni usporedbom podataka pokazuju kako se u klopkama ''M'' tipa nalazio veći broj potkornjaka, a ujedno i više vrsta potkornjaka. Tako je najbitnija vrsta potkornjaka na ovom području (Ips sexdentatus) zabilježena u 2 – 3 puta većim brojkama u klopkama ''M'' tipa. Za vrstu Orthotomicus erosus i još poneke vrste potkornjaka, utvrđeno je da je gotovo nemoguće ''sačuvati'' ulov u klopkama ''S'' tipa kada se sakupljanja obavljaju jednom mjesečno, jer dolazi do redukcije broja potkornjaka u lovnim posudama od strane predatorskih vrsta - Temnochila caerulea i Thanasimus formicarius. Osim toga klopke ''M'' tipa pokazale su nešto manju selektivnost prema navedenim vrstama predatorske entomofaune. S obzirom da se u operativi danas koriste uglavnom klopke ''suhog'' tipa, podaci koji su dobiveni prilikom ovog istraživanja mogu poslužiti prilikom odabira optimalnijeg tipa klopke za primjenu u feromonskom monitoringu borovih potkornjaka

Abstract (english)

In the area of m. u. ''Borovača'', UŠP Split, in order to collect data that can be used to prevent and reduce the damage caused by the mass occurrence of pine bark beetles, a three-month study was conducted using cross-vane flight barrier traps WitaPrall®. Two pheromone traps were placed on two experimental plots, one of which was of the "wet" type and the other of the "dry" type. Collections were performed once a month, and the results obtained by comparing the data show that in the "M" (wet) type traps there were a larger number of bark beetles, and at the same time more species of bark beetles. Thus, the most important species of bark beetle in this area (Ips sexdentatus) was recorded in 2-3 times higher numbers in "M" type traps. For the species Orthotomicus erosus and some other species of bark beetles, it was found that it is almost impossible to "save" the catch in traps of the "S" (dry) type when collecting is performed once a month, because there is a reduction in the number of bark beetles in hunting container by predatory species - Temnochila caerulea and Thanasimus formicarius. In addition, "M" type traps showed somewhat less selectivity for these species of predatory entomofauna. Considering that mainly "dry" type traps are used in the operative today, the data obtained during this research can be used in selecting the more optimal type of trap for use in pheromone monitoring of pine bark beetles.
