Leptoglossus corculus (Say) and Tetyra bipunctata (H.-S.) are pests of slash pine (Pinus elliottii) and other pines grown for seed in the south-eastern United States. The inconspicuous damage caused to the seeds by the bugs is described. A rapid radiographic method of detecting the damage in mature seeds they cause was compared with an accurate but time-consuming ocular method using a magnification of 60. Of field-collected seeds diagnosed by the ocular method as having sustained damage, 82% were also correctly diagnosed by radiography.
