The abundance of bottom fauna and of fauna in drift was studied in streams treated with DDT at various times in the past. Recovery of the bottom fauna was found to be rapid, but that of drift was delayed. The relationship of quantity of drift to the

The outbreak of the spruce budworm (Choristoneura fumiferana (Clemens)) from 1970 to 1985 has declined drastically in Maine, remaining only in about 2000 ha along the southeast coast. Because a new, severe outbreak may not be anticipated for a few de

Strip clearcutting contributed to dispersal losses of early-instar larvae of the spruce budworm. Choristoneura fumiferana (Clemens) (Lepidoptera: Tortricidae). Significantly more L1 larvae were trapped in uncut residual strips of strip clearcuts than

Coincident populations of spruce budworm, Choristoneura fumiferana (Clem.) and spruce coneworm, Dioryctria reniculelloides (Mutuura and Munroe) were studied to compare spatial distribution, temporal abundance, relative abundance on spruce species, an

A population index for the estimation of the neosistens stage of pine leaf chermid on white pine is described. This is based on the observation that increasing numbers of the chermid produce increased stunting of length of pine needles. A regression

Emodin, a mixture of anthraquinones, occurs in the Rhamnaceae and functions as a deterrent to foliage-feeding insects. There was little attack on foliage of Rhamnus alnifolia in wild stands compared with associated species of woody plants. Anthraquin

Residue analysis of forest soils sprayed once at 1 lb/acre showed little breakdown of DDT through 9 years after application. In the absence of appreciable downward trend, residue persistence could not be estimated beyond stating that it appears to pe
