Monitoring the occurrence and population density of the European shot-hole borer (Xyleborus dispar F.) in almond plantations

Voćni sipac (Xyleborus dispar F.) je primarni i sekundarni štetnik gotovo svih voćnih vrsta. Štetnik se javlja tokom proljeća u odraslom obliku, a ženka nakon kopulacije traži potencijalno stablo u koje će se ubušiti i formirati sljedeću generaciju. Istraživanje je provedeno na području Šibensko-kninske županije, u mjestu Lađevci, u dva nasada badema, površine 0.1 ha. Pojava te visina populacije voćnog sipca je utvrđena pomoću lovki koje se sastoje od crvenih ljepljivih ploča i plastičnih boca s mješavinom vode i 70% -tnog etilnog alkohola, u omjeru 1:1. Tijekom praćenja ulovljeno je sveukupno 35 jedinki. Najveći ulov zabilježen je početkom travnja a iznosio je 22 jedinke, te se potom smanjuje do kraja perioda istraživanja u kojem se dobio uvid u kretanje populacije na istraživanom području.European shot-hole borer ( Xyleborus dispar F.). is the primary and secondary pest of almost all fruit species. The pest occurs during the spring in adult form, and the female in the spring looks for a potential tree into which it could drill and form the next generation. The research was conducted in the area of Šibenik-Knin County, in village Lađevci, in two almond plantations, surface 0,1 ha. The appearance and population height of the European shot-hole borer was determined with the help of traps consisting of red adhesive plates, a plastic bottle filled with water and 70% ethyl alchol, in a ratio of 1:1. During monitoring, the total catch was 35 individuals. The largest catch was recorded in early April twenty-two individuals, and then decreased by the end of the research period, in which insight into population movments in the study area was obtained
