Diversity of wasps (Hymenoptera: Vespidae) in conventional and organic guarana (Paullinia cupana var. sorbilis) crops in the Brazilian Amazon. Repositório Alice
SOMAVILLA, A.; SCHOENINGER, K.; CASTRO, D. G. D. de; OLIVEIRA, M. L.; KRUG, C..
Diversity of wasps (Hymenoptera: Vespidae) in conventional and organic guarana (Paullinia cupana var. sorbilis) crops in the Brazilian Amazon. The present study aimed to determine the diversity of wasp species associated with the guarana crop and the difference in composition of species associated to organic and conventional crops, as well as among environments established in each management (adjacent forest, crop edge and guarana crop).

HIGH-PERFORMANCE GEL FILTRATION PATTERNS OF VENOMS FROM THREE SPECIES OF WASPS OF THE GENUS Polybia (HYMENOPTERA, VESPIDAE) J. Venom. Anim. Toxins
PALMA,M. S.; MANZOLI-PALMA,M. F.; GOBBI,N..
The profiles of high-performance gel filtration of venoms from Polybia paulista, Polybia ignobilis and Polybia occidentalis occidentalis showed 13 peaks distributed among the three species. These profiles presented similarities that permitted the chromatographic characterization of the genus Polybia and differences that permitted the identification of each species studied. Thus, the comparative analysis of chromatographic profiles of high-performance gel filtration of venoms may be used as an auxiliary tool in taxonomic studies of Polybia wasps.

Pollinators of Oxypetalum (Asclepiadaceae) in Southeastern Brazil BJB
VIEIRA,M. F.; SHEPHERD,G. J..
Floral visitors of seven species of Oxypetalum were registered in Viçosa, State of Minas Gerais. O. appendiculatum, O. banksii subsp. banksii, O. alpinum var. alpinum and O. pachyglossum are pollinated by wasps, being Polybia ignobilis (Vespidae) a pollinator of these four species. It seems that P. ignobilis promotes interspecific pollinations mainly between O. alpinum var. alpinum and O. pachyglossum, two species with very similar floral morphology. O. jacobinae, O. mexiae and O. subriparium are pollinated by bees. Wasps and bees carry one, two, three or several pollinaria in the mouthparts. O. mexiae, an endemic species in Viçosa, seems to present reproductive limitations, since its flowers are seldom visited.

The third trophic level of plant defence: neotropical social wasps' use of odours of freshly damaged leaves when hunting Zoologia
Raw,Anthony.
An important aspect of the hunting strategy of neotropical social wasps (Hymenoptera: Vespidae) is where they hunt. Three species used two behavioural components in their selection of a place to search for prey. The wasps uti lizcd the odour of freshly damaged leaves as cues (which could be synomones) to select which leaves to inspect and also they remembered a place to which they were strongly attracted to hunt recently and returned there. Polybia ignobilis (Haliday, 1836) and Polistes satan Bequaert, 1940 hunted on a lawn of Digitaria diversinervis Stapf immediately after it was mown in significantly larger numbers than at other times. P. ignobilis and Polistes versicolor (Olivier, 1791) hunted in significantly greater numbers on freshly cut leaves of...

Two new species of social wasps (Hymenoptera, Vespidae) from Roraima, Northern Brazil Zoologia
Raw,Anthony.
The females and nests are described of two new species of social wasps (Hymenoptera, Vespidae) from dry evergreen forest on the Ilha de Maraca, Roraima, Brazil. Mischocyttarus (Monocyttarus) maracaensis sp.n. closely resembles M. flavicornis Zikan, 1935 in morphology and coloration. Polybia (Myrapetra) roraimae sp.n. is a member of the P. occidenlalis (Olivier, 1791) group of species.
