Abstract

Spatial segregation between the colonial homopterans Aphis vernoniae Thomas and Publilia reticulata Van Duzee on New York ironweed, Vernonia noveboracensis L., does not occur either among plant patches or among plants. Before August, spatial separation occurs on the plants, with A. vernoniae concentrated in the inflorescences and P. reticulata concentrated on the middle leaves. Apparent overlap increases as A. vernoniae moves onto senescing leaves late in the season. However, the A. vernoniae colonies are found nearer to the petiole, and there is little actual overlap in the distributions of the two species.

Résumé

La ségrégation spatiale entre les homoptères coloniaux Aphis vernoniae Thomas et Publilia reticulata Van Duzee vivant sur les Vernonia noveboracensis L., ne se produit pas entre groupes de plantes, ni entré plantes. Avant août la séparation est observée sur les plantes, A. vernoniae étant concentré sur les inflorescences, et P. reticulata l'étant sur les feuilles médianes. Le chevauchement apparent augmente alors que A. vernoniae se déplace vers les feuilles sénescentes tard en saison. Cependant, les colonies de A. vernoniae se retrouvent plus près du pétiole et il n'y a en fait que peu de chevauchement dans la distribution des deux espèces.
