VARIATION IN SOUTHERN PINE BEETLE ATTACK HEIGHT ASSOCIATED WITH PHORETIC UROPODID MITES1

Abstract
Abstract

Southern pine beetles (Dendroctonus frontalis) carrying phoretic Trichouropoda australis deutonymphs were caught in bucket traps baited with frontalin-alpha pinene at heights of 3, 6, and 9 m on the boles of loblolly pines. Of 8475 beetles collected, 36.3% carried uropodids or their pedicels. Beetles trapped at 3 m carried more pedicels than those trapped at 6 or 9 m, indicating that the flight of beetles is influenced by the presence of phoretic mites. Re-emerging parent beetles can be differentiated from brood adults by the color of the mite pedicels.
