| Des pertes considérables du rendement, de la qualité et de la commercialité des cultures ont été attribuées à la larve de taupin, un ravageur qui préoccupe sans cesse davantage et dont la distribution progresse en Nouvelle-Écosse et partout au Canda. Alors que les Maritimes abritent des espèces indigènes de la larve de taupin, trois espèces introduites en Amérique du Nord par les eaux de ballast des navires européens causent la majeure partie des dommages. La larve destructrice de ces trois espèces, Agriotes lineatus, A. obscurus, et A. sputator, demeure dans le sol pendant de nombreuses années, se nourrit des racines des plantes hôtes et réduit considérablement le rendement et la qualité de cultures importantes au plan économique. Les plantes cultivées... |

| Spatio-temporal distribution, combined with aspects of insect biology and ecology can influence the infestation risk of the key pea pest Cydia nigricana in vegetable- and field peas. The proximity of pea fields of the previous cultivation period highly affects the infestation potential of the moth. The presented study aims to monitor the infestation development in three different regions in Germany (North Hesse, Saxony, Saxony-Anhalt) in four consecutive years and to relate empirical pest incidences to key factors as crop abundance, the distance to previous pea fields, the pea plant phenology and climatic conditions. In a next step, these data will form the basis for the elaboration of a computer-aided decision support system, which assists farmers in... |

| Significant losses in crop yield, quality and marketability have been attributed to wireworms, a pest of growing concern and widening distribution in Nova Scotia and across Canada. While the Maritime Provinces harbour indigenous wireworm species, three species introduced to North America from European ship ballast cause the lion's share of damage. The destructive larvae of these three species, Agriotes lineatus, A. obscurus, and A. sputator, persist in the soil for several years, feeding on the roots of host plants and causing significant reductions in the yield and quality of economically important crops. Root crops such as potatoes and carrots are particularly susceptible because damage (holes produced by feeding larvae) to the new tubers and carrots... |
