Ants obtained from trees of a "Jacareuba" (Calophyllum brasiliense) forest plantation in Central Amazonia by canopy fogging: first results
Provedor de dados: Acta Amazonica
Autores: HARADA,Ana Yoshi; ADIS,Joachim.
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...

ESTRATIFICAÇÃO E DENSIDADE DE INVERTEBRADOS EM SOLO ARENOSO SOB FLORESTA PRIMÁRIA E PLANTIOS ARBÓREOS NA AMAZÔNIA CENTRAL DURANTE A ESTAÇÃO SECA
Provedor de dados: Acta Amazonica
Autores: HARADA,Ana Yoshi; BANDEIRA,Adelmar Gomes.
Densidade e distribuição vertical de invertebrados foram estudados durante o mês de setembro de 1990 e 1991, em solo de três tipos de cobertura vegetal: floresta primária, plantios de Dipteryx odorata(Leguminosae = cumaru) e Simaruba amara(Simarubaceae = marupá), nos arredores de Manaus, Brasil. Foram encontrados 19 grupos principais da fauna. A maioria desses grupos foram similares para os três tipos de cobertura, sendo Isoptera (40,1%), Formicidae (25,2%), Araneae (6,7%) os grupos mais abundantes que, juntos, representaram 62,4% da fauna de cumaru, 57,0% da fauna de marupá e 84,1% da fauna de floresta. Houve uma diminuição da densidade para todos os grupos (excluídos os cupins) até a profundidade de 20 cm, com subseqüente aumento até 30 cm de...

Arthropods obtained from the Amazonian tree species "Cupiuba" (Goupia glabra) by repeated canopy fogging with natural Pyrethrum
Provedor de dados: Acta Amazonica
Autores: ADIS,Joachim; HARADA,Ana Yoshi; FONSECA,Claudio Ruy V. da; PAARMANN,Wilfried; RAFAEL,José Albertino.
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.
