A solid longitudinal black stripe is evident on the hind legs (Figure 5). Yield losses result if entire pods are consumed, but even moderate feeding on the pods will break the integrity of the pod, resulting in premature shattering and subsequent yield loss. This fungus may occasionally reach epidemic proportions. These species start to hatch in early May and because of their small size at this time, are easily distinguished from the species that overwinter as larger nymphs. ). Before cultivating the trap strips, allow three days to assess the effectiveness of the insecticide.
