Summary
The study aimed to find out correlation between number of individuals and the amount of damage caused by Nezara viridula (L.) (Hemiptera: Pentatomidae) and to determine which stage of N. viridula cause the most damage on bean pod. For this purpose, 3 individual groups consisting of 10, 15 and 20 individuals were put to feed for 5 days separately in the observation cages, each of them were placed on bean plants in the manner involving a pod. At the end of the 5th day, individuals removed from the observation cages and total sucking-spot areas on the pods were calculated by measuring symptoms in square millimeter (mm(2)). Experiments conducted in a controlled climate room conditions at temperature 25 +/- 1 degrees C, relative humidity 45% +/- 5% and photoperiod 16:8 h.
