Abstract

In 1976, the alydid, Alydus pilosulus (H.-S.), was first recorded in small numbers on the research plots at Princess Anne, MD. But in 1977, it was observed in pest proportions and also a corid, Leptoglossus oppositus (Say), was recorded for the first time. Though the stink bugs were not observed to be more numerous than in the previous years, the total damage from feeding by all the heteroptera was assessed by obtaining five yellow or green pods from the uppermost portion of the plant and five pods from the lowest part of the same plant; ten plants were sampled from a 9' x 20' plot.
