Loblolly pine trees struck by lightning offer a favorable attack and brood environment for the southern pine andIpsbeetles. In central Louisiana lightning strikes reduced oleoresin exudation pressure, oleoresin flow, and relative water content of inn

The southern pine beetle, Dendroctonus frontalis Zimmerman, passed through 7 (and a partial 8th) consecutive development periods in field-infested bolts kept in an outdoor insectary in east Texas in 1962. This phenomenon suggested that approximately
