Longleaf pine seedworm

Cydia ingens (Heinrich) (Lepidoptera: Tortricidae)

Orientation to pest

Longleaf pine seedworm, Cydia ingens (Heinrich), is a native tortricid that is part of the Cydia toreuta complex whose members cannot be separated morphologically and whose species status is uncertain (Gilligan et al. 2008). Species are currently recognized based on host and range. Cydia ingens (in the narrow sense) has been interpreted as being restricted to Florida. This species, or closely related forms, occur in the southeastern United States where their larvae feed in immature cones of long leaf pine (Pinus palustris Mill.), destroying the seeds.

Hosts commonly attacked

There are many seed cone worms, associated with various pines. In the southern United States this species, or a closely related one, feeds on long leaf pine (P. palustris).


This species complex is found in the southeastern United States, with C. ingens (in the narrow sense) perhaps being restricted to Florida.
