| This study describes the reproductive system of Stachytarpheta maximiliani (Verbenaceae), including its floral biology, nectar and pollen availability and insect foraging patterns, identifying whose species act as pollinators. It was carried out in a Brazilian Atlantic rain forest site. Observations on the pollination biology of the Verbenaceae S. maximiliani indicate that their flowering period extends from September through May. Anthesis occurs from 5:30 a.m. to 5:00 p.m. and nectar and pollen are available during all the anthesis. Many species of beetles, hemipterans, flies, wasps, bees and butterflies visit their flowers, but bees and butterflies are the most frequent visitors. The flowers are generally small, gathered in dense showy inflorescences. A... |

| O objetivo desta pesquisa foi avaliar a dinâmica populacional de Phyllocnistis citrella Stainton, (Lepidoptera: Gracillariidae), o minador-dos-citros, em pomares de tangerineira Citrus deliciosa Tenore variedade Montenegrina e de tangoreiro híbrido "Murcott" Citrus sinensis L. Osbeck X Citrus reticulata Blanco, com manejo orgânico, em Montenegro (29° 68'S e 51° 46'O), Rio Grande do Sul. Foram realizadas amostragens quinzenais de julho de 2001 a junho de 2003. Os brotos coletados foram examinados em laboratório e submetidos à análise do número de folhas por broto, a da presença ou ausência de minas, do número de minas, dos ovos, das larvas e das pupas de P. citrella. Em ambos os pomares não houve registro de minas de P. citrella no primeiro fluxo de... |

| Clear habitat separation between the sister species Colias alfacariensis and C. hyale is shown when occurring sympatrically. Colias hyale is found more often in moist cultivated pastures while Colias alfacariensis is more abundant in dry uncultivated habitat. Out of a total of 16 loci, no diagnostic loci were found between C. alfacariensis and C. hyale, and both species shared most major polymorphisms. Exceptions were the marked differences in allele frequencies at the HK locus and only C, hyale, but not C. alfacariensis was further invariable at the GOT2 locus, which is usually highly polymorphic in the Pieridae. Colias hyale has a significantly lower level of heterozygosity than its sister species C. alfacariensis. In Colias alfacariensis heterozygosity... |

| Global warming and the change of butterfly distributions: a new opportunity for species diversity or a severe threat (Lepidoptera)? In order to assess the influence of climatic changes on the distribution of insects, the ranges of nonmigratory European butterfly species have been studied. This study revealed that the northern limits of 32 (64%) of 52 species have expanded northwards during the 20th century. The southern limits of ten (25%) of 40 species have retracted northwards. The example of the Peacock butterfly (Inachis io) is given to illustrate the response to climatic changes of a species of which the range is not restricted by habitat choice. The northern limit of its range shows a considerable shift to the north during warm periods, and a... |

| Fifteen species of Aguna Williams, 1927 (Hesperiidae: Pyrginae) are known from near Cacaulàndia in central Rondônia, Brazil; nine represent undescribed species. These nine, plus four additional new species discovered among material from other areas, are named and described: Aguna latifascia, Aguna coeloides, Aguna nicolayi, Aguna latimacula, Aguna penicillata, Aguna spicata, Aguna longicauda, Aguna panama, Aguna spatulala, Aguna similis, Aguna mesodenlala, Aguna squamalba, Aguna parva. The species of Aguna are placed into ten species groups based upon the characters of the male and female genitalia. These groups are described and their included species are discussed. Aguna williamsi Hayward, 1935, new synonymy is considered synonymous with Eudamus... |

| The Anticarsia gemmatalis is responsible for the use of chemical insecticides in the soybean culture, causing a significant increase in the costs of farming and a great unbalance in the ecosystem. The use of microbial agents, like Bacillus thuringiensis serovar kurstaki (Btk) and Anticarsia gemmatalis nucleopolyhedrovirus (AgNPV), they are an alternative to chemical control of the pest insects. In the interaction analysis of the entomopathogenic bacteria and virus it is considered important the in vitro action mode of these microbiology control agents. Therefore, the present study aims the histopathological analysis of the A. gemmatalis larvae digestive system after the interaction in vivo of the entomopathogenic Btk and AgNPV, represented the Dipel and... |

| The identity of hitherto doubtful specific names in Nepticulidae has been established on the basis of type material where possible, or after a critical reexamination of the original descriptions. In addition a few previously synonymized names have been reevaluated. The identity of 17 names could be firmly established: 15 are synonymized with senior, well known names, two are senior synonyms to previously used names: Stigmella sakhalinella Puplesis (= S. discidia Schoorl & Wilkinson syn. nov.) and Trifurcula subnitidella (Duponchel) comb. nov. (= Trifurcula griseella Wolff syn. nov.). Two names are tentatively synonymized. Three names are excluded from Nepticulidae: Tinea commatella Schrank, 1802 (probably a trichopteron), Tinea minimella Costa... |

| ABSTRACT The present paper describes the immature stages of the Neotropical satyrine butterfly Euptychia mollina (Hübner, [1813]) from the Brazilian Amazon Forest. Eggs were laid singly on the under surface of the fronds of its host plant, Selaginella sp. (Briophyta: Selaginellaceae). Larvae are solitary in all instars, presenting a color pattern and shape that make them cryptic on its host plant. The pupa is short, smooth and varies from rusty brown to green. Despite the lack of a close phylogenetic relationship, larvae of Euptychia are very similar to those of the paleotropical satyrines Ragadia and Acrophtalmia, suggesting that camouflage is likely to be one of the factors explaining the similarities among them. |
