Spread Rate
Larvae of this pest can move within infested nuts, the adults are not very mobile; this insect takes 2 to 3 years to develop through one generation so this limits the ability to quickly develop high populations.
2
Spread Amount
Found in pecan growing areas from New York to Iowa, south to Oklahoma and across the southeastern states from Florida to Texas, occasionally found in New Mexico but does not occur in Arizona, seems this species would survive well in CA.

Ecological
Increased insecticide usage would result to manage this pest if it established - this would threaten environmental quality; could also impact seed (acorn) production in oaks as well as other affected species.

Agricultural
Primarily a pest of pecan and hickory and to a lesser degree walnuts, oaks, beech, and hazelnut.

Detection
Inspection of nuts is the best way to detect the larvae, adults can be sampled by banding trees and with non-pheromone traps, but these methods would only be effective locally; adult feeding and larval infestation leave signs that can be observed.
3
Control
Well-timed insecticide applications made to commercial pecans are commonly used.
