Resumo: | Canopies of the locally occurring Amazonian tree species Calophyllum brasiliense. Camb. (Guttiferae, height 10 m) were fogged after dawn on the same day at five adjacent localities in a 20-year-old plantation at the Adolpho Ducke Forest Reserve near Manaus/Brazil, using natural pyrethrum (0.5%, 1.0%, 1.5%), Baythroid (0.3%) and diesel oil, respectively. The 1152 ants collected represented 52 species, 17 genera and five subfamilies. The highest number of ant species was obtained with the synthetic pyrethrum Baythroid 0.3% and with natural pyrethrum 1.5%. About 46% of the total ant species were only collected in the first hour after fogging, and 17% only during the second hour, after trees had been heavily shaken. About 73% of the total ant specimens dropped in the first hour. Data on alpha-diversity, eveness and frequency of ants indicated a rapidly decreasing knock-down effect of both the synthetic and natural pyrethrum after application. The ant fauna in the canopy of C. brasiliense is somewhat distinct compared with that of Goupia glabra Aubl. (Celastraceae, height 45 m) from the primary forest of the reserve.
