ABSTRACT
The objective of this research was to know the diversity of arthropods associated to the Pleurotus sajor-caju crop in rice straw pasteurized in a semicontrolled environment, located in the south of the state of Rio Grande do Sul, Brazil. The capture of specimens was carried out in the period of April through May 2007, during the phase of fruit bodies of the crop, lasting 45 days. Nine collections with intervals of 5 days were carried out, using INTRAL AL 012 (12 volt) traps. A total of 3129 individuals divided into five orders with predominance of Diptera (2874), Hymenoptera (152), Ortoptera (69), Colembola (59) and Coleoptera (38) was captured. The Diptera order was the one that presented the biggest number of families, being Mycetophilidae (2530), Sciaridae (264), Cecidomyiidae (10), Phoridae (46), Muscidae (4), Calliphoridae (1) and Culicidae (19).
