Abstract:The dry weight of pecan foliage, Carya illinoensis (Wang) K. Koch, destroyed by a given larva of Datana integerrima Grote and Robinson may be partitioned as follows: the 1st 3 instars together destroyed ca. 2.5% in 14.14 days, the 4th instar destroyed an additional 11.5% within the next 4.25 days and, allowing 1 day for molting, the 5th instar destroyed the remaining 86% in less than 3.5 days, and the majority of that occurred within the last day and a half. A total of 3.36 g of foliage was consumed by the typical walnut caterpillar larva during its development.
