Abstract

Emerging Trichoptera were collected from the littoral zone of a newly-created reservoir, Southern Indian Lake, Manitoba, from 1977 to 1981. The relationship between caddisfly emergence and lake shoreline type, depth of sampling, and shoreline erosion rate was studied. Twenty-five species of Trichoptera were collected; six species of Polycentropodidae comprised almost 75% of the total number of individuals. Abundance and richness of Trichoptera were correlated with shoreline stability, with higher abundance and richness being found at more stable (i.e. lower erosion) shorelines. Highest numbers of Trichoptera emerged in 1981, 5 years after impoundment. Maximum abundance and richness of Trichoptera was found at 3.5 m depth, which is also the depth at which maximum deposition of organic matter occurred. Agrypnia straminea Hagen, a case-maker, dominated the trichopteran fauna at the marsh shoreline; species of net-spinning Polycentropodidae dominated at the clay shorelines. Patterns of species composition and abundance in 1982 artificial substrate collections were similar to those found in 1977–1981 emergence trap collections. Interspecific differences in Neureclipsis capture nets may explain the greater abundance of N. validus (Walker) than N. bimaculatus (L.) at a high erosion shoreline.

Résumé

On a recueilli des Trichoptères en période d'émergence de la zone littorale d'un nouveau réservoir, le lac Southern Indian (Manitoba) de 1977 à 1981. On a étudié la relation entre l'émergence des phryganes et le type de rivage, la profondeur d'échantillonnage et le taux d'érosion du rivage. On a compté vingt-cinq espèces de Trichoptères; près de 75% des insectes échantillonnés appartenaient à l'une ou l'autre de six espèces de Polycentropodidés. On a étudié la corrélation entre l'abondance et la variété des Trichoptères, d'une part, et la stabilité du rivage, d'autre part; les échantillons étaient plus nombreux et variés sur les rives les plus stables (c.-à-d. les moins érodées). C'est en 1981, soit cinq ans après la formation du réservoir, que les Trichoptères étaient le plus nombreux. Le nombre et la variété des insectes échantillonnés étaient maximum à 3,5 m de profondeur, c'est-à-dire là où le dépôt de matière organique était maximal. Agrypnia straminea Hagen, espèce à fourreau, dominait les Trichoptères recueillis sur la rive du marais; des Polycentropodidés tisseurs de toiles dominaient sur les rives argileuses. Les captures réalisées au moyen de substrats artificiels en 1982 étaient semblables aux échantillons prélevés au moyen de pièges de 1977 à 1981 pour ce qui est de l'abondance et de la répartition des espèces. Les différences interspécifiques observées chez les Neureclipsis capturés au filet expliqueraient peut-être la plus grande abondance de N. validus (Walker) par rapport à N. bimaculatus (L.) sur un rivage fortement érodé.
