Figure 1. Seasonal cycle of E. juglandis in Alabama. Points of Adult/Egg line labeled 82, 83, 88, and May 1, 1984, are dates on which ovipositional sign was first detected in those years; other points labeled 84 and those designated 85 represent dates when oviposition was witnessed. On the Larva line, points in May are dates newly hatched larvae appeared on leaflets; points in June/July are dates of disappearance of the last larva in those years. Broken portions of the Prepupa line represent estimated extensions of the prepupal period; broken Pupa line represents the pupal period estimated from 1984-85 sampling data.
