Sažetak
In Croatian ecological areas, species which bionomy are less known, are to be identified and circumstances for their development, determined in order to predict their show up and in rational ways prevent them from creating damage to the least possible measure. The species Helicoverpa armigera Hubner, cotton bollworm was determined in 2003 and 2004 in west Istria on vegetables plots in a massive population. By monitoring the larvaes on tomato and bell pepper we estimated the place and share of damaged fruits. Damaged fruits of tomato and bell pepper were noticed in the surroundings of Porec and Rovinj in 2003, while damages on tomatoes were noticed in river Mirna valley in 2003 and 2004. The mean loss of yield due to damage on the tomato fruits in 2003 in Porec was 33% and in Rovinj 37%. In Mirna river valley, this loss was 42% (2003)and 13% (2004). Damages in about 25% in Rovinj and 35% in Mirna river valley, were noted on bell pepper in 2003. The most larvaes on tomatoes were 15 to 40 mm long while on bell pepper they were 30 mm long. Also in 2004 we determined thr appearance of Beosus maritimus (two-spotted ground bug) on cabbage and oilseed rape. On cabbage fields there were 248 bugs per square meter, while on oilseeds rape fields there were 322 bugs per square meter. Also this bug usually couses no damage on cabbage becaouse it is feeding on dad organic matter ; but its appearance caused panic among inhabitants in Vrsar. On the road Vrsar - Limski canal hordes of bugs were crossing the road and creating a slippery and smelly mass.
