Abstract
Vespidae is an important insect family that is among the largest predators of other insects in natural environments. This study in mangrove swamps was carried out in order to know if social wasp, Mischocyttarus (Mischocyttarus) rotundicollis could be attracted by fish (sardine) in decomposition. The insects were collected in mangrove swamps in Itaborai, every two weeks, totaling 72 samples from August 2008 to July 2011. Over a 36 months period 69 individuals were caught. The abiotic factors (season and tidal variations) that could influence the occurrence of these wasps in mangrove swamps were recorded. The abundance of wasps was only affected by the spring season and the highest tides (spring-tides). The presence of the M. rotundicollis, in the mangrove swamps caught with fish in decomposition, may indicate that the studied forest area still represents a natural preserved refuge and reveals the importance of understanding of ecology these wasps and provides much information that will contribute greatly to environmental sciences.
Highlights
Among all the Brazilian ecosystems, the mangrove divided in six subfamilies: Eumeninae, Masarinae, swamp is perhaps the most impacted, due to intense Euparagiinae, Stenogastrinae, Vespinae and Polistinae human interference

Summary
Largest predators of other insects in natural environments. This family has approximately 4,600 species and is. Discharged into mangrove swamps (Kamaruzzaman et al, 2008) These two impacts have caused physical changes to the swamp environment (Gandaseca et al, 2011) and caused the death of many endemic species or changes in the structure of invertebrate colonies (Johnston and Keough, 2002). This study of wasp Mischocyttarus rotundicollis in the mangrove swamps of Itaboraí (RJ) was carried out in Vespidae is an important insect family that is order to know if this species could be attracted by fish included in the order Hymenoptera and is among the (sardine) in decomposition in the Guapi-Mirim. There are no studies showing this type of bait as attractive for this species, which increases the need for this study
