Here's what I found Semo Hunter.
U.S. Forestry Service: Osage-Orange
Osage-orange trees are attacked by at least four stem borers: the mulberry borers (Doraschema wildii and D. alternatum) (4), the painted hickory borer (Megacyllene caryae), and the red-shouldered hickory borer (Xylobiops basilaris) (8). The twigs are parasitized by several scale insects including the European fruit lecanium (Parthenolecanium corni), the walnut scale (Quadraspidiotus juglansregiae) the cottony maple scale (Pulvinaria innumerabilis) the terrapin scale (Mesolecanium nigrofasciatum), and the San Jose scale (Quadraspidiotus perniciosus) (25,46). The fruit-tree leafroller (Archips argyrospilus) feeds on opening buds and unfolding leaves.
Osage-orange is attacked by, but is not a principal host of, the fall webworm (Hyphantria cunea) (55), an Eriophyid mite, Tegolophus spongiosus (51), and the fourspotted spider mite, Tetranychus canadensis (4).
