| ABSTRACT Cryptophion Viereck, 1913 is a small Neotropical genus of Campopleginae, with seven described species, two recorded from Brazil. In this paper, a new species from the Atlantic Forest of southeastern Brazil is described and illustrated. In addition, a key to the Brazilian species is provided. Cryptophion atlanticus sp. nov. (holotype female deposited in DCBU: Brazil, São Paulo, São Luiz do Paraitinga, Parque Estadual da Serra do Mar) is diagnosed by mesoscutum more or less uniformly punctate, except the notaular region with coarser and irregular rugae, scutellum bearing irregular lateral longitudinal rugae; forewing with areolet not distinctly petiolate above and hind tarsal claw pectinate, but with a large space in the middle, and distinctly... |

| The geographic ranges of Heimbra opaca (Ashmead, 1894), H. bicolor Subba Rao, 1978 and H. parallela Stage & Snelling, 1986 are extended based on study of material deposited in the entomological collections of the Laboratório de Sistemática e Bioecologia de Parasitoides e Predadores da APTA (Ribeirão Preto, SP, Brazil) of the Instituto Brasileiro de Geografia e Estatística (Brasília, DF, Brazil). Symbra potiguara Perioto & Fernandes sp. nov. (Hymenoptera, Eurytomidae) is described, illustrated and compared with S. cordobensis Stage & Snelling, 1986, the single species previously known for this genus. A key to the genera of Heimbrinae and to the species of Symbra is provided. |

| Abstract: The objective of this work was to determine the biological parameters and thermal requirements of Trichogramma pretiosum TM strain reared on Helicoverpa armigera eggs. A card containing 20 eggs of H. armigera was offered for each T. pretiosum female, at temperatures of 18, 20, 22, 25, 28, 30 and 32°C. All life stages of T. pretiosum were observed under the given temperature conditions. The optimum temperature for the parasitism of T. pretiosum was 25°C, and the highest longevity was found at the same temperature. The highest parasitoid emergence rates occurred at temperatures of 22, 25 and 28°C. The highest proportion of T. pretiosum individuals emerged per egg was observed at 18°C. Concerning the sex ratio, the highest proportion of females... |

| Among the pests of cassava, the shoot fly, Neosilba perezi (Romero & Ruppell), is one of the most prevalent. It attacks mainly the terminal shoots and causes infested plants to produce lateral shoots. Reports on this species are rare or inexistent; thus, the purpose of this study was to assess three different areas for N. perezi infestation. The survey began in March 2008 and finished in February 2009. Fortnightly analyses were performed starting 45 days after planting, calculating the rate of infestation by N. perezi larvae in each study area. The areas were correlated separately for each parameter: fortnightly mean temperature, fortnightly mean rainfall, and plant age. The N. perezi larvae occurrence rate was higher in area 1 - which presented... |

| The wasps of the "Proctotrupoidea complex" (Ceraphronoidea, Proctotrupoidea y Platygasteroidea) are a very large and diverse group of parasitic Hymenoptera. It is a relatively old group, with fossils from the Jurassic period. All of them are parasitoids or hiperparasitoids of other arthropods, attacking most groups of terrestrial insects as well as centipeds and spiders. The present study summarizes the knowledge of this complex in Brazil. A total of 221 species are listed; they are distributed in the families Ceraphronidae (1), Megaspilidae (1), Diapriidae (84), Monomachidae (9), Pelecinidae (2), Proctotrupidae (12), Platygastridae (20), Scelionidae (92). Taxonomy, fossil records, distribution and hosts are reviewed. |

| This is the first study about galls, gall makers and associated fauna of the Ecological Station of Jataí. Galls are plant structures formed by abnormal growth of cells, tissues or organs induced by several organisms, as fungous, nematoids and insects. Five areas of the conservation unity, two in the phytophysionomy of cerrado in regeneration and three in the cerradão area were studied, totalizing 69 morphotypes of galls on 41 host species from 24 families. This is the first record of Annonaceae as the richest family in morphotypes in Brazil; 34 gall makers and associated fauna were identified, which 23 Diptera (67.4%), eight Hymenoptera (23.5%), two Hemiptera (5.8%) and one Thysanoptera (2.9%). Were described 41 new morphotypes of gall and made the first... |

| ABSTRACT: From those of the mealybug family, the citrus mealybug, Planococcus citriRisso, 1813 (Hemiptera: Pseudococcidae) is frequently held responsible for various diseases occurring in vineyards. This is a first time report in Brazil, on the occurrence of a parasitoid controlling P. citri. In our search for the natural enemies of P. citri, bunches of grapes with the vine were collected every week for one month, in those regions where table grapes were produced, like Petrolina, Pernambuco, Brazil. In these samples, among the natural pest infestations Coccidoxenoides perminutusGirault, 1915 (Hymenoptera: Encyrtidae) was the only natural enemy species reported. In this research, we attempted to study the potential of parasitism as well as the strategies... |

| The nesting behaviour of the solitary wasp Tachysphex inconspicuus (Kirby) was comparatively studied based on observations made in two environmentally distinct locations in southeast Brazil: upper portions of two sandy beaches and a dirt road in a forested area. Motor patterns related to nest construction were similar in all observed wasps, but some behavioural features, which were different among the observed wasps in the two environments, seem to be constrained by ecological factors. T. inconspicuus can be behaviourally differentiated from several other species of the genus by the following combination of features: they close the nest temporarily during its provision, do not let the excavated sand to form into a mound in front of the nest entrance,... |

| Phymastichus coffea LaSalle is an African endoparasitoid of adults of the coffee berry borer, Hypothenemus hampei (Ferrari) that was introduced into Mexico for biological control purposes. The objective of this study was to investigate the oviposition behavior of P. coffea on its host under laboratory conditions. The results indicate that P. coffea females exhibited 12 behavioral acts during and after oviposition, such as, walking, cleaning, flying, surface landing, resting, host landing, host antennation, touching the host with forelegs, host recognition, walking on the host, oviposition and cleaning after oviposition. The sequence of each behavior is described in an ethogram. |

| The present research aimed to elucidate which aspects of immune responses in Diatraea flavipennella are suppressed by the parasitoid Cotesia flavipes, thus, ensuring parasitism success. We investigated the presence of apoptosis in fat body cells through the TUNEL technique. According to the results, reduced levels of nitric oxide and phenoloxidase activity were observed in larvae parasitized for three days, and reduced total number of hemocytes, after three and seven days. An increase in plasmatocytes and decrease in spherulocytes numbers were observed in the differential count on the third day of parasitism. The number of melanized microspheres in parasitized larvae was low and indicated less intense melanization. The ultrastructural analysis confirmed... |

| Many insects host facultative, bacterial symbionts that confer conditional fitness benefits to their hosts. Hamiltonella defensa is a common facultative symbiont of aphids that provides protection against parasitoid wasps. Protection levels vary among strains of H. defensa that are also differentially infected by bacteriophages named APSEs. However, little is known about trait variation among strains because only one isolate has been fully sequenced. Generating complete genomes for facultative symbionts is hindered by relatively large genome sizes but low abundances in hosts like aphids that are very small. Here, we took advantage of methods for culturing H. defensa outside of aphids to generate complete genomes and transcriptome data for four strains of... |
