Abstract

Two canopies of a widely distributed Amazonian tree species, Goupia glabra Aubl. (Celastraceae, height 38 and 45m) were fogged several times with 1% natural pyrethrum during the rainy and dry seasons (1991-1994) in the Adolpho Ducke Forest Reserve near Manaus/Brazil. Between 50 and 158 ind./m2 of arthropods were obtained per tree and fogging event. Hymenoptera, mostly Formicidae, and Diptcra dominated. A total of 95 ant species occurred on a single tree. Most ants were permanently foraging in the canopy and their recolonization after fogging seems to follow stochastic pathways. Data indicated an interaction between - 1) predating Formicidae and gall building Cecidomyiidae and - 2) Cecidomyiidae and the parasitic Hymenoptera.Duas copas de uma espécie de árvore amplamente distribuída na Amazônia, Goupia glabra Aubl. (Celastraceae, altura 38 e 45m) foram renebulizadas várias vezes com píretro natural 1%, durante o período chuvoso e seco (1991-94) na Reserva Florestal Adolpho Ducke próximo de Manaus/Brasil. Entre 50 e 158 ind./m2 de artrópodos foram obtidos por árvore e evento de nebulização. Hymenoptera, na sua maioria Formicidae, e Diptera dominaram. Um total de 95 espécies de formigas ocorreram numa única árvore. A maioria das formigas estava permanentemente forrageando na copa e a sua recolonização depois a nebulização parece seguir vias estocásticas. Os dados sugerem uma interação entre Formicidae e Cecidomyiidae (construindo galhas) e Cecidomyiidae e Hymenoptera parasítica.
