Abstract

Mountain pine beetles, <i>Dendroctonus ponderosae</i>, were marked with fluorescent (DayGlo) powders in vacuum chambers and on powder-covered brood trees in the field for use in release-recapture studies of dispersal behaviour. A large wall tent was used as a field insectary to accelerate late stages of development of large numbers of beetles in naturally infested bolts of lodgepole pine. Up to 28% of the marked beetles which flew were recovered from lethal trap trees. Beetles self-marked on powdered brood trees were captured in barrier traps in predicted proportions.
