Abstract:: The bark beetle infestation in ponderosa pines defoliated by pine looper, Phaeoura mexicanaria (Grote) on Cook Mountain was resurveyed in 1971. Most of the surviving defoliated trees have "greened up" appreciably. Bark beetle activity was greatly reduced. The red turpentine beetle, Dendroctonus vaZens LeConte, was the only bark beetle observed...

Abstract:: Epidemic levels of the pine butterfly, Neophasia menapia (Felder and Felder) have been evident in ponderosa pine stands in the Bitter Root Valley since 1969. Evaluations of this infestation were initiated in 1970 to assess overwintering egg populations at 20 locations within the infestation (Ciesla et al. 1971). Defoliation was...

Abstract:: A granular controlled release formulation of 2 percent MCH was applied at 4.48 kg/ha to 76.9 ha of uninfested, windthrown Douglas-fir by helicopter with a modified aerial spreader of 1.12 m capacity in May 1982. Douglas-fir beetle population reduction was 96.4 percent by late June. With one exception, treated plots...

Three other small areas in the Missoula Valley were infested also. Overwintering populations of larvae are low; thus, light defoliation is expected in 1979 in presently infested...
