For strain selection studies of natural enemies from the field, studies of behavior or even of taxonomy, capture of alive insects are of great importance. One alternative for obtaining adult parasitoids (Hymenoptera) is the use of emergency traps. Therefore, the objective of this work was to propose two models of emergency traps (traps like “box” and “bottle”), for obtaining alive endophytic egg parasitoids. The two models proposed were efficient in the capture of alive parasitoids, however a larger capture of specimens was observed in the “box” trap in relation to the e “bottle”, due to larger folioles storage inside the …

The knowledge of the diversity and distribution of ground arthropods contributes for the development of sustainable agricultural systems. This work was carried out at the Paulista State University, Jaboticabal campus, State of São Paulo, Brazil, during the period from February to April 2004. The objective was to analyse the community of Carabidae, Staphylinidae, Formicidae e Araneae through faunistic indexes, to determine the spatial distribution and interespecific interactions of predominant species in soybean (Glycine max (L.) Merr.), corn (Zea mays L.) and rubber tree (Hevea brasiliensis Muell. Arg.). The arthropods were sampled by pitfall traps distributed each 10 m in two …
