| Abstract A new species of Diolcogaster (Hymenoptera: Braconidae) is described and illustrated. Additionally, its position within the recently published key to New World species of the xanthaspis species-group (to which the described Diolcogaster belongs) is provided. The gregarious larval parasitoid Diolcogaster choi sp. nov. was collected in Maringá, Paraná State, Brazil. This natural enemy was recovered from a caterpillar of Hypercompe cunigunda (Stoll, 1781) (Lepidoptera: Erebidae) that was feeding on plant of passionflower, Passiflora edulis Sims (Passifloraceae). The fauna of the xanthaspis group in the New World now includes five species, including the new species from Brazil described in this paper. Diolcogaster choi sp. nov. differs anatomically,... |

| Phenology of the Braconidae (Hymenoptera, Ichneumonoidea) at Área de Proteção Ambiental of Descalvado, São Paulo State. The flight phenology of the Braconidae fauna was conducted using Malaise traps in five sites of the Environmental Protected Area of Descalvado. A total of 2,792 specimens, representing 22 subfamilies, was sampled throughout a period of sixteen months from May, 1999 to August, 2000. The traps catches for koinobionts peak was in August, 1999 a month before of the idiobionts peak and in June, 2000 both peaks were simultaneous. The phenological peaks of dominant koinobiont taxa (Microgastrinae) were similar to all koinobionts, and the peaks of dominant idiobiont taxa (Doryctinae) were similar to all idiobionts, as well. December, 1999 and... |

| Functional response of Telenomus remus Nixon (Hymenoptera, Scelionidae) to Spodoptera frugiperda (J. E. Smith) (Lepidoptera, Noctuidae) eggs: effect of female age. Functional response of 24-h and 48-h-old Telenomus remus adults was studied on Spodoptera frugiperda eggs. The study was carried out in climatic chamber regulated at 25 ± 1°C, 70 ± 10% RH and 12:12h (L: D). Females of T. remus were honey fed and individualized in glass vials along with 25, 50, 75, 100, 150, 200, 250 or 300 eggs of S. frugiperda for 24 h. Complete randomized design with ten replications was adopted. The parameters evaluated to construct the functional response curve were daily average parasitism, searching rate and oviposition time. It was observed that the higher the egg... |

| Parasitoid Hymenoptera collected in a soybean plantation (Glycine max (L.)) Merril (Fabaceae) at the municipal district of Nuporanga, SP, Brazil. Parasitoid Hymenoptera were collected by using Moericke trap placed in a soybean plantation (Glycine max (L.) Merril) (Fabaceae) of the variety Conquista, during the period of March 24th to April 7th, 2000. A total of 4,969 specimens of parasitoids, belonging to seven superfamilies and 15 families, were collected. Scelionidae, Encyrtidae, Aphelinidae and Trichogrammatidae were the most common families, being responsible for 41.66%, 19.42%, 11.19% and 7.35% of the total number of parasitoids collected, respectively. Other eleven families showed the relative frequency lower than 5%. |

| 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... |

| Onion is the third most grown vegetable crop in São Paulo state, Brazil. Organic onion farming is expected to increase in the state due to the increasing demand. Pest management in organic onion farming is based on plant extracts with insecticide effects. However, the efficacy of such plant extracts has not been proved yet, and it was observed that they do negatively affect natural enemies. Plants surrounding onion fields, and that are attractive to natural enemies, may be a good option to farmers, since they may lead to increased diversity of arthropod species and, consequently, the natural control of pest populations. This study deals with the effect of marigold plants as a resource plant to natural enemies in onion fields. The experiment was set in a... |

| The ability of Trichospilus diatraeae Cherian and Margabandhu, 1942 (Hymenoptera: Eulophidae) to search and parasitize Diatraea saccharalis (Fabricius, 1794) (Lepidoptera: Crambidae) pupae in sugarcane stalks was evaluated. To analyze the ability for search and parasitism were used stalks of sugarcane (20 cm) where it was introduced a pupa of D. saccharalis (T1); a pupa and a caterpillar (T2) or a pupa and fecal matter (T3). Each stalk was placed in a transparent plastic bottle with 21 females of T. diatraeae. These pupae were isolated, after 72 h, in glass tubes at 25 ± 2 °C, 70 ± 10 % relative humidity, 14:10 light/dark. The experiment was developed in an entirely casualized design with three treatments and 12 repetitions. Percentage of D. saccharalis... |

| O presente trabalho teve por objetivo avaliar a ação residual dos produtos etofemprox, fenitrotiom, metidatiom e triclorfom sobre adultos de Trichogramma pretiosum, bem como sobre as gerações F1 e F2 desse parasitóide, em condições de laboratório. Ovos do hospedeiro alternativo Anagasta kuehniella (Zeller) (Lep., Pyralidae) foram aderidos em cartelas de cartolina azul, inviabilizados sob lâmpada germicida e tratados por imersão nas soluções inseticidas e em água destilada (testemunha) por cinco segundos. Os ovos foram expostos ao parasitismo uma, 24 e 48 horas após o tratamento, por um período de 24 horas, e posteriormente mantidos em câmara climatizada a 24±1ºC, UR de 70±10% e 12 horas de fotofase até a emergência dos parasitóides.... |

| 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... |

| The effect of the hyphomycete Paecilomyces fumosoroseus (Wise) Brown & Smith on the predatory and parasitic activity of Aphelinus asychis Walker, a common parasitoid of the Russian wheat aphid, Diuraphis noxia (Mordvilko), was investigated under three different humidities. Three cohorts of 20 female A. asychis were treated with 5.2 x 10(4) spores/cm² (twice the LD95 for D. noxia). Each female was then individually maintained in a ventilated Petri dish in which were placed three barley leaves and 20 third-instar D. noxia. Cohorts of 20 treated females were each held at one of the following relative humidities along with an equal number of untreated control insects: 67-73%, 85-89%, and 94-98%. Every 24 hours over a period of one week, the surviving... |
