| Systematics, phylogeny and geographical distribution of the South American species of Centris (Paracentris) Cameron, 1903, and Centris (Penthemisia) Moure, 1950, including a phylogenetic analysis of the "Centris group" sensu Ayala, 1998 (Hymenoptera, Apoidea, Centridini). A cladistic analysis with the objective of testing the hypothesis of monophily of Centris (Paracentris) Cameron, 1903, and of studying its phylogenetic relationships with the other subgenera that belong to the Centris group, sensu Ayala, 1998, and the relationships among the species that occur in South America, is presented. Centris (Paracentris) is a group of New World bees of amphitropical distribution, especially diversified in the Andes and in the xeric areas of South and North... |

| Searching and handling time of Chrysoperla externa (Hagen, 1861) (Neuroptera, Chrysopidae) larvae fed on Uroleucon ambrosiae (Thomas, 1878) (Hemiptera, Aphididae). The objective of this research was to determine the searching and handling times of three larval instars of C. externa fed on U. ambrosiae at densities of 30, 40 and 50 per vial, with the feeding of the larvae at the preceding instars being U. ambrosiae nymphs or Sitotroga cerealella (Olivier, 1819) eggs. The larvae were maintained at 25 ± 2 ºC, 70 ± 10% RH and a 14-h photophase. A completely randomized design in a 6 x 3 factorial scheme with 12 replicates was adopted. The shortest searching time was found for the 2nd and 3rd instar larvae of C. externa, and this parameter was variable depending... |

| The Ichneumonidae (Hymenoptera) of the Estação Ecológica of the Universidade Federal de Minas Gerais, Belo Horizonte, with emphasis on the Pimplinae species. In one annual cycle 83,712 insects were captured, of which 2,339 were Ichneumonidae, belonging to 17 subfamilies; they were collected by a Malaise trap placed in a montane semidecidual seasonal forest, inside the campus. Among the collected ichneumonids there were 13 genera and 30 species of Pimplinae, of which Pimpla croceiventris was the most frequent species. The species richness of Pimplinae was greater in the ecological station in Belo Horizonte, MG than in other localities studied. |

| Parasitoid Hymenoptera (Insecta, Hymenoptera) collected in a cotton (Gossypium hirsutum L.) (Malvaceae) plantation at the municipal district of Ribeirão Preto, SP, Brazil. Parasitoid Hymenoptera were collected by using Moericke trap placed in a cotton plantation (Gossypium hirsutum L.) of the variety Delta Pine 90, during the period of February 23rd to April 3rd, 2001. A total of 16,166 specimens of parasitoids, belonging to eight superfamilies and 22 families, were collected. Encyrtidae, Trichogrammatidae, Mymaridae and Scelionidae were the most common families, being responsible for 45.14%, 19.11%, 14.33% and 6.57% of the total number of parasitoids collected, respectively. Other eigthteen families showed the relative frequency lower than 5%. |

| Revision of the genus Paramecocephala Benvegnú, 1968 (Heteroptera, Pentatomidae). The Neotropical genus Paramecocephala Benvegnú, 1968 is revised based on morphological characters, particularly of the genitalia of both sexes. Formerly monobasic with P. foveata Benvegnú, 1968, type species, the genus received two species recently transferred from Mecocephala Dallas, 1851: M. fusca Haglund, 1868 and M. uruguayensis Pirán, 1970. Five new species are herein described: P. australis Frey-da-Silva & Grazia sp. nov., P. bachmanni Frey-da-Silva & Grazia sp. nov., P. bergrothi Frey-da-Silva & Grazia sp. nov., P. guianensis Frey-da-Silva & Grazia sp. nov. and P. subsolana Frey-da-Silva & Grazia sp. nov.

| Biological characteristics of Nipteria panacea Thierry-Mieg (Lepidoptera, Geometridae), an avocado tree defoliator, in highlands areas of Espírito Santo, Brazil. The objective of this research was to evaluate some biological characteristics of the avocado tree defoliator, Nipteria panacea Thiery-Mieg, in laboratory. This species showed the mean development cycle of 58.1 days, embryonic period of eight days and egg viability 56.3%. Pos-embryonic development lasted 36.5 days with viability of 48.2%, pupal period 11.6 days with viability of 76.0%, and mean longevity of females was 19.5 days with a production of 177 eggs per female. Other parameters were also observed and discussed. |

| A reanalysis, based on museum specimens, of our previously published data on the geographical distribution of the species of Drosophila belonging to the cardini group in Brazil is presented and discussed. As previously recorded in several papers, including ours, the following four species were recognized: D. cardini, D. cardinoides, D. neocardini, and D. polymorpha. However, it was realized that most of the flies we have previously identified as Drosophila cardinoides belong in fact to Drosophila cardini. To facilitate the proper identification of these four near-sibling species, their holotypes were analyzed and their terminalia were described and illustrated. A key to the four species is also provided. |

| The subgenus Centris (Aphemisia) Ayala: complementary notes and description of a new species (Hymenoptera, Apoidea). Centris (Aphemisia) Ayala, 2002 is redescribed pointing out some others important distinctive characters. The nominal species designated by Ayala as the type species, Centris plumipes Smith, 1854, is preocupied by Centris plumipes (Fabricius, 1781) originaly described in Apis Linnaeus. Being so, Centris xanthosara nom. nov. is proposed to replace Centris plumipes Smith, 1854 non Centris plumipes (Fabricius, 1781). Two other species are considered to belong in this subgenus: Centris (Aphemisia) lilacina Cockerell, 1919, and Centris (Aphemisia) plumbea sp. nov., from Tingo Maria, Peru.

| Highly eusocial bees (Hymenoptera, Apidae) flower visitors in a continental sand dune ecosystem from the medium São Francisco River, Bahia, Brazil. A community of highly eusocial bees in sand dunes, covered with caatinga vegetation, in the medium São Francisco River, Bahia (10º47' 37"S and 42º49' 25"W) was studied. The local climate is semi arid and hot, with mean temperature of 25.7 ºC and annual precipitation of 653.8 mm. Censuses took place every two months, from February to December of 2000. The bees were sampled on flowers with entomological nets, from 6:00 a.m. to 5:00 p.m. A total of 2,147 individuals of eight species of Apinae were found, of which Apis mellifera Linnaeus (40.2%), Trigona spinipes (Fabricius) (28.7%) and Frieseomelitta silvestri... |
