| The oviposition behaviour of Gryon gallardoi (Brèthes, 1914) on eggs of Spartocera dentiventris Mendonça Jr. (Berg, 1884) of different ages (2, 3, 4, 5, 6, 7, 8 and 12 days) was investigated. Groups of 12 eggs of each age were exposed to single females of G. gallardoi, and the oviposition behaviour was recorded under a stereomicroscope for two hours. Ten replicates were used for each age. In order to identify the moment the parasitoid egg was released inside the host, 1-day old eggs of S. dentiventris were exposed to G. gallardoi females, and the oviposition was interrupted at intervals of 20, 40, 60, 80, 100, 120, 140 and 160s after ovipositor insertion had initiated. Five behavioural steps were recorded: drumming, ovipositor insertion, marking, walking... |

| 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... |

| This study aimed to identify natural enemies of the chinch bug, Blissus antillus Leonard, which attacks Tanner grass (Brachiaria arrecta) and Tangola (hybrid of B. arrecta and B. angola), in poorly drained pastureland in the northern region of Rio de Janeiro State. Immature stages of a parasitic mite, identified as Leptus sp. (Parasitengona: Erythraeidae), were commonly found attacking nymphs and adult chinch bugs in all sampled areas of Rio de Janeiro State. An egg parasitoid, Eumicrosoma sp. (Hymenoptera: Scelionidae), was observed on only two occasions attacking eggs which had been collected on plant stems in the field. These natural enemies are possible candidates for biological control programs. Despite extensive sampling, B. antillus was not observed... |

| 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. |

| A survey was conducted in Brasília, DF, from January 1999 to March 2001, on tobacco, cotton, tomato, cabbage, soybean, bean, melon, eggplant and the weed Emilia sonchifolia DC, to collect natural enemies of the whiteflies Bemisia tabaci (Gennadius) and Trialeurodes vaporariorum (Westwood). Fourteen predators, twelve parasitoids and two hyperparasitoids were collected. Among the parasitoids, Encarsia inaron (Walker) is recorded for the first time in South America, and E. basicincta Gahan is a new record for Brazil. E. aleurothrixi Evans & Polaszek is recorded for the first time parasitizing B. tabaci. The lady beetles Nephaspis hydra Gordon and Delphastus davidsoni Gordon are registered for the first time preying on B. tabaci. |

| 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 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,... |

| Fruits were collected over a 12-year period to determine the host status for the Carambola fruit fly, Bactrocera carambolae Drew & Hancock, and other tephritid species in Suriname, South America. Over 11,000 fruit samples were collected from many locations and the total of 20 fruit species were recorded as host, ranging in infestation from heavy to occasional. Over 650 samples of 188 fruit species, including many wild species, were collected and no fruit flies were reared. This work, which started specifically to obtain information on the Carambola fruit fly, resulted also in detailed information regarding the importance, distribution and host preferences of several Anastrepha species, and the status of fruit fly parasitoids. |

| We investigated two populations of Melittobia digitata Dahms, a gregarious parasitoid (primarily upon a wide range of solitary bees, wasps, and flies), in search of Wolbachia infection. The first population, from Xalapa, Mexico, was originally collected from and reared on Mexican fruit fly pupae, Anastrepha ludens Loew (Diptera: Tephritidae); the other, from Athens, Georgia, was collected from and reared on prepupae of mud dauber wasps, Trypoxylon politum Say (Hymenoptera: Crabronidae). PCR studies of the ITS2 region corroborated that both parasitoid populations were the same species; this potentially provides a useful molecular taxonomic profile since females of Melittobia species are superficially similar. Amplification of the Wolbachia surface protein... |

| New distribution records of 22 braconid species belonging to Agathidinae, Braconinae, Helconinae, Homolobinae and Rogadinae subfamilies from Brazil, Chile, Costa Rica, Guatemala, Mexico and Panama are presented. Agathirsia ninesevenci Pucci & Sharkey is reported for the first time from Mexico; Homolobus acares van Achterberg, H. antefurcalis van Achterberg and H.infumator (Lyle) from Costa Rica; Triaspis kurtogaster Martin from Brazil, Costa Rica and Panama.
