| Insects are essential to tropical ecosystems functioning. In semi-arid regions, the increase in abundance and/or activity (e.g. reproduction and foraging behavior) of insects is usually associated with climatic variables. The present study investigates which climatic variables are best predictors of insect abundance in an area of Caatinga in northeastern Brazil. Individuals were sampled for 24 months using Malaise and pitfall traps, and beating trays. A total of 58925 individuals belonging to 20 insect orders were collected. The most abundant orders were Hymenoptera, Diptera, Collembola and Coleoptera. Most orders studied showed a clear maximum abundance in the rainy season. Rainfall and humidity were the best predictors of insect abundance in the... |

| The oviposition behaviour of the braconid parasitoid, Compsobracon mirabilis ( Szépligeti, 1901) is described. Observations were conducted in a cerrado region located in Três Marias, Minas Gerais, Brazil. The oviposition occurred in a branch of Alibertia concolor (Cham.) K. Schum. 1889 (Rubiaceae), inside of which there were thirteen larvae of an unidentified species of Lepidoptera. |

| A new species of Homalocerus Schoenherr from the Atlantic coast of the State of São Paulo, Brazil (Coleoptera, Belidae, Belinae), with notes on color pattern and on the sclerites of the internal sac. Homalocerus bimaculatus sp. nov. (type locality: Brazil, São Paulo) is described and illustrated, and comments on the sclerites of the internal sac of aedeagus and on color pattern are provided. The new species is compared to other similar species of the genus, being distinguished by having three clusters of carmine pubescence on pronotum and two lateral whitish oval spots located slightly before the middle of each elytron. Six species of Homalocerus, including the new one, are known from the State of São Paulo. The previously published identification key for... |

| 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 São José dos Pinhais, Paraná, Brazil. Biological, molecular and morphological characters were used to confirm the identity of the specimens. Parasitoid identification presented a challenge since the species has most diagnostic characters of the genus Cotesia Cameron, but few in the poorly defined genus Parapanteles Ashmead. Based on morphological and molecular evidence, we transfer Parapanteles scotti to the... |

| The effect of environment on development and survival of pupae of the necrophagous fly Ophyra albuquerquei Lopes (Diptera, Muscidae). Species of Ophyra Robineau-Desvoidy, 1830 are found in decomposing bodies, usually in fresh, bloated and decay stages. Ophyra albuquerquei Lopes, for example, can be found in animal carcasses. The influence of environmental factors has not been evaluated in puparia of O. albuquerquei. Thus, the focus of this work was motivated by the need for models to predict the development of a necrophagous insect as a function of abiotic factors. Colonies of O. albuquerquei were maintained in the laboratory to obtain pupae. On the tenth day of each month 200 pupae, divided equally into 10 glass jars, were exposed to the environment and... |

| ABSTRACT The genus Neogriphoneura Malloch, 1924 is currently composed of 11 species with New World distribution. Neogriphoneura timida Curran, 1942 is recorded for the first time in South America, with occurrences in Brazil, Colombia and Trinidad and Tobago; and new Central American records are presented: Belize, Honduras and Mexico. Here we redescribe the species and present, for the first time, illustrations of the male terminalia and female spermathecae, and discuss the main diagnostic characteristics of external morphology. A brief discussion about the postcopulatory sexual selection in this species is proposed based on morphology of the spermathecae. |

| Alticini fauna from five areas, two with different types of management (Borda and Araucaria) and three with different levels of conservation (Fase 1, Fase 2 and Fase 3), in the Araucaria Forest of the Parana was captured with malaise traps. The material was collected weekly, from September/1999 to August/2001, in the Parque Estadual of Vila Velha, Ponta Grossa. 1,891 individuals of 106 Alticini species were collected with only seven species common to all areas. Despite the proximity between sampling areas, the number of species shared between pairs of areas was low, not reaching 40%, with the Araucaria and Fase 1 areas being the most similar. The community structure of the areas Fase 1 and Fase 2 were most related. Fase 1, in initial stage of succession,... |

| O estudo objetivou conhecer, ao longo das estações do ano, aspectos ecológicos da população adulta de Culex quinquefasciatus em abrigos. As coletas dos adultos foram realizadas mensalmente, cobrindo-se o período de um ano, na vegetação da margem de um canal de circunvalação. Os insetos foram capturados com o auxílio de um aspirador à bateria. O material foi acondicionado e transportado ao laboratório e, posteriormente, a espécie de interesse foi identificada; machos e fêmeas foram quantificados e o desenvolvimento ovariano foi identificado segundo o critério de Sella. Dados metereológicos foram coletados visando correlacioná-los com a variação sazonal da população de mosquitos. Foram coletados 8.298 mosquitos da espécie Culex quinquefasciatus. Desse total,... |
