Pheromone traps were placed in the market place in B anja L uka, and in greenhouses and open field tomato crops, on 13 September 2010 to determine the presence of T uta absoluta ( M eyrick) ( L epidoptera: G elechiidae) in B anja L uka region. Based on examination of traps, the presence of T . absoluta was confirmed for the first time in the R epublic of S rpska. Only mines of L iriomyza species were found by examining leaves under a stereomicroscope. In 2011, pheromone traps were placed in greenhouses at several locations ( B anja L uka, P rijedor, N ovi G rad, K ozarska D ubica, L jubinje and T rebinje) at the beginning of J une, and in open fields in B ijeljina and T rebinje at the beginning of S eptember. Examination of the traps was carried out at intervals of 15 days. A sample of 100 leaves, taken from 20 randomly selected plants, was examined in order to evaluate the intensity of the attack. The first adults were caught in greenhouses in L jubinje and T rebinje on 18 June 2011; in open field crops in B ijeljina on 9 S eptember 2011 and in B anja L uka on 5 O ctober 2011. Adults were not captured in P rijedor, N ovi G rad or K ozarska D ubica, and no mined leaves were observed. The intensity of attack was evaluated on the basis of active infestation (percentage of leaves with active mines compared with all mined leaves). The strongest intensity of active infestation was recorded in the open field crops in T rebinje, where 19% of leaves with active mines were found.
