Tb19: Parasites Of Potato-Infesting Aphids In Northeastern Maine, W. A. Shands, Geddes W. Simpson, C. F. Muesebeck, H. E. Wave
Technical Bulletins
This publication presents brief synopses of the biology of several of the more common species or genera of primary parasites and of hyperparasites occurring in northeastern Maine. Three approaches are discussed for increasing effectiveness of insect parasites against the potato-infesting species of aphids, including (1) the introduction of new species of parasites or strains of species better adapted and more effective against each species of aphid than the naturally occurring ones, (2) the mass releasing of parasites in potato fields at times critical for the population dynamics of the aphids, and (3) a combination of these. The combined-effort approach is …
