1. Odontadenia lutea (Apocynaceae) LEAVES: PHYTOCHEMICAL STUDY AND INSECTICIDAL ACTIVITY AGAINST LEAF-CUTTING ANTS Atta sexdens rubropilosa Forel
The present work describes the chemical constituents of Odontadenia lutea (Vell.) Markgr. leaves and the toxicities of its extract and fractions against Atta sexdens rubropilosa Forel (Hymenoptera: Formicidae). Chromatographic procedures of the ethanolic extract resulted in the identification of the triterpene β-amyrin, the flavonoid rutin, two fatty acids

2. Proteomic analysis of the venom of the social wasp Apoica pallens (Hymenoptera: Vespidae)
ABSTRACT Wasps are a diverse group of insects that possess a sting apparatus associated with a venom gland, which is used for predation and colony defense. The biochemistry of Hymenoptera venom has been evaluated in relation to allergy and immunology, and proteomics has been shown to be a powerful tool for the identification of compounds with pharmacological

3. Natural diet of Ocypode quadrata (Fabricius, 1787) (Crustacea, Decapoda, Brachyura) from the Northern Coast of São Paulo, Brazil
Abstract Decapod crustaceans have a wide variety of feeding habits, alternating among herbivory, predation, saprophagy, and filtration. The occupation of various trophic positions in the food web is a key feature in the evolution of the group. Thus, we analyzed the natural diet of the crab Ocypode quadrata (Fabricius, 1787), commonly known as the ghost crab

4. First record of Cotesia scotti () (Hymenoptera: Braconidae: Microgastrinae) comb. nov. parasitising Spodoptera cosmioides (Walk, 1858) and Spodoptera eridania (Stoll, 1782) (Lepidoptera: Noctuidae) in Brazil
ABSTRACT This is the first report of Cotesia scotti (Valerio and Whitfield) comb. nov. in Brazil, attacking larvae of the black armyworm, Spodoptera cosmioides, and the southern armyworm, S. eridania. The moth larvae were found respectively, infesting a protected cropping of organic tomato in Hidrolândia, Goiás, Brazil, and a transgenic soybean crop in Sã

5. Occurrence of Amblycerus species in Cordia trichotoma seeds and their influence on germination
ABSTRACT Forest species can have their seeds damaged by granivorous insects, especially by those in their larval stage. In this context, this study aims to report the occurrence of Amblycerus species in Cordia trichotoma seeds, to describe their main damage to seeds and effects on germination, as well as their associated hymenopteran parasitoids. Therefore,

8. Altitudinal effects on diversity of Pimplinae (Hymenoptera, Ichneumonidae) from Southeast Brazil and description of new species
Resumo Neste estudo a diversidade de Pimplinae em três diferentes altitudes na Reserva Biológica da Serra do Japi, Jundiaí, SP, Brasil foi investigada com um total de 18 gêneros e 91 morfoespécies capturadas por armadilhas Malaise. Nas altitudes baixa e alta ocorreram maior abundância e riqueza em gêneros, respectivamente. Na altitude intermediária o

9. A new species and new records of minuta-group Gnamptogenys from Brazil (Hymenoptera: Formicidae)
ABSTRACT We report new records of Gnamptogenys caelata Kempf (1967) and Gnamptogenys minuta (Emery, 1896) from Brazil. We also describe Gnamptogenys piei n. sp. from Southeast Brazil. This distinctive new species is known only from a single worker found in leaf litter from montane forests of the Mantiqueira mountains in Itatiaia National Park, Rio de Janeiro

10. Taxonomic notes on social wasps of the groups of Mischocyttarus wagneri (Buysson 1908) and M. barbatus Richards 1945 (Hymenoptera, Vespidae, Polistinae)
ABSTRACT Taxonomic revisionary notes and identification keys are presented for two species-groups of wasps of the genus Mischocyttarus, subgenus Phi. Material of the M. wagneri and M. barbatus groups, including types, was examined in several collections, resulting in description of one new species for the first mentioned group (M. camanducaia sp. nov.), and

11. Phylogeny and new species of the Neotropical bee genus Paroxystoglossa Moure (Hymenoptera, Apoidea)
ABSTRACT Paroxystoglossa is a solitary, ground-nesting bee genus. It was revised in 1960 and currently includes nine species from Argentina, Brazil and Paraguay. The objectives of this contribution are to provide a morphological phylogeny for the group and to describe two new species: P. levigata n.sp. and P. mourella n.sp. Paroxystoglossa is monophyletic an

12. Screening for quality indicators and phenolic compounds of biotechnological interest in honey samples from six species of stingless bees (Hymenoptera: Apidae)
Abstract Honey from stingless bees of the genus Melipona is a well sought product. Nevertheless lack of legal frameworks for quality assessment complicates the evaluation of food safety and marketing of these products. Seeking to assess the quality of honey from the bees of this genus, physical and chemical analyses, identification of phenolic compounds, and
