Abstract

In four studies with loblolly pine bolts over a 2-year period, absence of the normal complement of mycangial and ectodermal fungi, or absence of mycangial fungi alone, caused a significant decrease in number of progeny, progeny/gallery, progeny/cm of gallery, and ratio of increase of Dendroctonus frontalis Zimmerman. Initial emergence of progeny was delayed 13 to 24 days. Absence of fungi had no effect on number of successful attacks, length of ovipositional gallery, and number of egg niches/cm of gallery.
