Abstract
Nezara viridula, Dolycoris baccarum and Eurydema ornata are polyphagous feeders attacking important major horticultural and field crops. Hosts include variety of weeds. These pests have cosmopolitan distribution and they are resistant to many pesticides. During 2016/2017, a sweep net method was used around the tobacco plots (ten replications/IO-day intervals) in the region of Prilep. The occurrence of D. baccarum and E. ornata was investigated on 100 tobacco plants/decade, in 4 replications. Samples of N. viridula were collected directly from tobacco leaves, and bred in the laboratories of Scientific Tobacco Institute. Dry warm weather 2016/2017 allowed development of phytophagous bugs (Pentatomidae, Hemiptera) on tobacco. The nymphs and adults fed on the upper or lower surface of the tobacco leaves. They injected saliva into the leaf tissue and suck up nutrients from plant juices. Tobacco leaves were pierced and deformed. N. viridula and D. baccurum were established in all development stadiums on tobacco and E. ornata only as an adult. The quantitative presence of investigated pentatomids was bigger in 2017. In August 2017 on surrounding weeds was identified great attack, 201 samples of N. viridula, 96 samples of D. baccarum and 58 samples of E. ornata. In September 2017, on top tobacco leaves we found 628 samples of D. baccarum and 243 samples of E. ornata. Individal samples of N. viridula fed on the margins of the tobacco plots. Investigated species are an economically -important pests in most of the areas in which they occurs. On tobacco plants they cause injury to plant tissues, reduce quality of tobacco and therefore, cause economic loss. Effective integrated control measures will reduce pest damage in tobacco production.
