Zusammenfassung
Six individuals of the palm A. phalerata (Arecaceae) in Poconé floodplains of Mato Grosso were sprayed with a syntetic pyrethroid of 0.25% concentration in order to study the biomass, diversity, and richness of arthropods associated with the crown. A total of 17,188 (238.780.6 ind./m²) arthropods collected on 72 m² funnel area were distributed in 22 taxonomic Orders. The Coleoptera (27.4%), Formicidae (19.0%), Collembola (13.6%), Psocoptera (10.7%), Diptera (9.0%) and Araneae (6.4%) predominated. Total biomass was 15.1 g dry weight (0.4mg/m²; 0.13+0.04/tree). Of the total arthropods obtained, 58.9% were collected within the first two hours after spraying, 37.6% within the next two hours following shaking of the trees, and a mere 3.5% after cutting and washing the palm fronds. A total of 4,715 beetles represented 48 families and 326 morphospecies were recorded. Tenebrionidae (22.9%), Curculionidae (22.0%), Carabidae (10.9%) and Staphylinidae (7.9%) contributed the highest density. Curculionidae (44 spp.), Staphylinidae (40 spp.) and Chrysomelidae (34 spp.) had the highest number of morphospecies. Trophic guilds of adult Coleoptera were dominated by herbivores (37.5%), followed by predators (35.4%), fungivores (14.6%), and saprophages (12.5%). Although most arthropod Orders were represented in all the palms sampled, analysis of variance showed no significant differences in their composition, however there was a significance difference in their frequency of occurrence.
