Abstract

The feeding behavior of the adults on soybean pods was observed for four stink bug species, Halyomorpha mista UHLER (Penttomidae), Riptortus clavatus THUNBERG (Alydidae), Nezara antennata SCOTT (Pentatomidae) and Piezodorus hybneri GMELIN (Pentatomidae) in the laboratory. The feeding duration and frequency per day were examined for each species. An exponential distribution was fitted to the observed frequency distribution of feeding duration. The insects randomly selected beans for feeding irrespective of the bean size and injury history of the bean except for the small and severely injured bean. The distribution of the total feeding duration per bean was expressed by a compound Poisson distribution. These matchematical models described the relationship between the insect density and bean damage.
