Popis: Species of zoophytophagous genus Dicyphina, plant bugs (Hemiptera: Miridae: Bryocorinae) are among the most abundant and effective predators of tomato pests. Nesidiocoris tenuis Reuter, 1895 (Hemiptera: Miridae) is the predominant species of Dicyphina sp. and it is considered to be a major natural enemy of insect pests in tomato crops in the Mediterranean region. This predatory bug is proved to be particularly successful in suppressing Tuta absoluta Meadow, 1917 (Lepidoptera: Gelechiidae), a major pest of tomato in greenhouse production. Aims of the study were to 1) investigate the efficiency of the mirid predatory bug N. tenuis in greenhouse tomato production and 2) to estimate the possibilities of its application in commercial vegetable production in Western Balkan countries of Europe. The significance of the study results relies on the possibility of commercialisation and general promotion of biological agent N. tenuis in tomato production in South East part of Europe, where the usage of pesticides still dominates the field of plant protection, both in vegetables and other agricultural sectors. According to the obtained results, the biological agent N. tenuis represents a reliable tool for controlling the level of the tomato leaf miner population by keeping the pest below its economic and intervention threshold.
Zoofitofagne vrste iz roda Dicyphina (Hemiptera: Miridae: Briocorinae) spadaju u grupu najzastupljenijih i najefikasnijih predatora štetočina paradajza. U usevima paradajza, vrsta Nesidiocoris tenuis Reuter, 1895 (Hemiptera: Miridae) je najzastupljeniji predstavnik roda Dicyphina i smatra se najvažnijim prirodnim neprijateljem štetočina paradajza u Mediteranskoj regiji. Ova predatorska stenica se pokazala posebno uspešno u suzbijanju moljca paradajza Tuta absoluta, 1917 (Lepidoptera: Gelechiidae), glavne štetočine u proizvodnji paradajza u zatvorenom prostoru. Ciljevi sprovedenog istraživanja su 1) ispitivanje efikasnosti predatorske stenice N. tenuis u proizvodnji paradajza u zatvorenom prostoru, odnosno 2) procena njene praktične primene u komercijalnoj proizvodnji povrća u zemljama zapadnog Balkana. Dobijeni rezultati doprinose promovisanju biološkog agensa N. tenuis i ukazuju na mogućnost komercijalne upotrebe ove predatorske stenice u proizvodnji paradajza u jugoistočnom delu Evrope, gde primena pesticida i dalje dominira u oblasti zaštite bilja, kako u povrtarstvu tako i u drugim poljoprivrednim sektorima. Prema dobijenim rezultatima, biološki agens N. tenuis predstavlja efikasno sredstvo za suzbijanje T. absoluta, kontrolom brojnosti populacije moljca paradajza ispod nivoa ekonomskog praga štetnosti.
