Estudo da entomofauna de solo do Campus de Pesquisas do Museu Emilio Goeldi

Abstract

The importance of the role played by insects in the world of living things becomes more appreciated every year, not only because of the great influence on agricultural productivity, but also due to the growing realization that many species are extremely valuable to man. The present work aims at surveying the soil entomofauna and identifying them at the level of major groups. Soil samples were taken in March/2002 (1st collection) and May/2002 (2nd collection) at five points on the research campus of the Goeldi Museum, using the Berlese Tullgren apparatus as extractor, over a period of five days. Partial results show that in the first collection a total of 520 individuals were obtained, with the following groups standing out: Acari (32,3%); Isoptera (23,1%); Hymenoptera (17,3%); Isopoda (11,1%); Collembola (4,2%); Thysanura (2,7%); Coleoptera (2%); Diptera, Chilopoda and Araneida (1,5%); Hemiptera (1,2%); Diplopoda and Anellida (0,8%). For the second collection, the result for only one point was 190 individuals, distributed thus: Hymenoptera (45.2%); Acari (15.8%); Isopoda (11.6%); Collembola and Araneida (5.2%); Coleoptera and Diplopoda (4.2%); Isoptera (3.7%); Thysanura, Hemiptera, Shymphylae Chilopoda (1.1%); Anellida (0.5%). These results indicate the groups of Acari, Hymenoptera (ants), Isoptera (termites) and Isopoda (garden armadillos) as dominant in the areas where the samples were collected.
