This study was conducted to investigate parasitism of naturally occurring pentatomid eggs in rice crops in a Cerrado-Caatinga ecosystem during the rainy and dry seasons in Teresina, Piauí, Brazil. Also, it provides information on the incidence and seasonality of parasitoid species. Parasitism was registered only during the rainy season, where Telenomus podisi (Ashmead, 1893) parasitized Oebalus poecilus (Dallas, 1851), Tibraca limbativentris (Stal, 1860) and Euschistus heros (Fabricius, 1798) eggs. Additionally, Trissolcus urichi (Crawford, 1913) was collected from O. poecilus and T. limbativentris eggs. Ooencyrtus anasae (Ashmead, 1887) was found in O. poecilus eggs. Such findings provide information that can be used to supplement the management of pentatomid pests in the rice agroecosystems, in Piauí, Brazil.

First record of egg parasitoids of Oebalus poecilus (Dallas, 1851) (Hemiptera: Pentatomidae) in rice in Maranhão, Brazil  This is the first report of the species Trissolcus urichi (Crawford, 1913) and Telenomus podisi Ashmead, 1893 (Hymenoptera: Platygastridae) parasitizing Oebalus poecilus (Dallas, 1851) (Hemiptera: Pentatomidae) eggs in rice in Maranhão, Brazil. These parasitoids were collected in the municipality of Itapecuru Mirim, MA, in an area of 0.2 ha cultivated with rice. The eggs collected exhibited an average parasitism of 11.4%. Twenty egg parasitoids were collected and identified, these being one Tr. urichi and nineteen Te. podisi. The presence of these naturally occurring parasitoids in the field opens perspectives for updating the species of parasitoids that parasitize pentatomid eggs in rice fields in Brazil.

The solitary egg parasitoids (Hymenoptera: Scelionidae) of Pentatomidae species complex are potential candidates for soybean (Glycine max L.) integrated pest management programs in Brazil. The correct identification of species and strains of these parasitoids is necessary to implement the use of biological control. Polymerase chain reaction (PCR) was used to generate random amplification of polymorphic DNA (RAPD) from male individuals of Telenomus podisi Ashmead and Trissolcus spp. collected in a soybean field in Brasília, Brazil in 1996. The analysis of 18 primers used to screen Trissolcus spp. individuals revealed different patterns related to the species analyzed. These results indicate the potential of RAPD markers to differentiate T. teretis Johnson, T. urichi Crawford and T. basalis (Wollaston). The 13 selected primers used to analyze T. podisi individuals produced 103 clear polymorphic scorable markers. Different genotypes were observed within this population analyzed, although the cluster analysis applied to the RAPD data showed high homogeneity (similarity >78.2%) among individuals.

Several stink bugs in the subfamily Pentatominae are crop pests or have the potential to damage plants of economic importance. In the Brazilian state of Rio Grande do Sul, where agriculture plays a major role in the economy, the knowledge about pest stink bugs is fragmented and, in some instances, outdated. This work provides a summary of Pentatominae species recorded in Rio Grande do Sul feeding on the four most important grain crops for the state, i.e. soybean, rice, maize, and wheat, plus canola, an emerging crop. This survey is enhanced with new records from scientific collections, a short diagnosis for each species, distribution maps, an identification key, and carefully illustrated to allow for species recognition in the field. With this work, we aim to reunite the scattered knowledge of the group in one single revision, and provide a useful tool for identifying the pest stink bugs of Rio Grande do Sul.

Abstract This is the first report on aquatic macrophytes in ponds of veredas (palm swamps) in the Cerrado (Brazilian savanna). We studied a pond in a vereda in Terenos, Mato Grosso do Sul state, central-western Brazil, during drought and flood periods to assess plant community structure and the relationship between species distribution and water depth. Sampling was carried out in five permanent transects, along which we placed sampling units of 1 m2 quadrats every 5 m. We estimated visually the relative cover of each species, bare ground, dead matter, and exposed water. We also measured water depth. We recorded 77 species of 49 genera and 31 families. The number of species varied between seasons, and in the rainy season the amphibious life form was predominant. The richest families were Poaceae (15 species), Cyperaceae (11), Asteraceae (4) and Lentibulariaceae (4). The richest genera were Rhynchospora (4), Utricularia (4), Eleocharis (4), Aeschynomene (3), Bacopa (3), Ludwigia (3) and Panicum (3). We found six new occurrences for the cerrado. Eleocharis acutangula had the highest relative cover (rainy and dry seasons), followed by Bacopa reflexa (rainy season), Paspalum lenticulare (rainy and dry seasons), Leersia hexandra (rainy and dry seasons), and Sagittaria rhombifolia (rainy season). Some species were distributed mainly at shallower depths, others occurred in deeper water, whereas some species varied greatly in terms of depth. Heliotropium filiforme and Ludwigia nervosa were found only in the dry season. In the rainy season, as expected, the exclusive species were mostly true aquatics.

This study aimed to identify parasitoid species of frugivorous larvae and to describe the tritrophic interactions involving wild fruits, frugivorous insects and their natural enemies at Adolpho Ducke Forest Reserve (RFAD) (Manaus, AM, Brazil). Collections were performed in four 1 km² quadrants in the corners of the RFAD. The wild fruits were collected inside the forest in access trails leading to each collection area and in trails that surrounded the quadrants, up to five metres from the trail on each side. The fruits were placed in plastic containers covered with thin fabric, with a vermiculite layer on the base to allow the emergence of flies or parasitoids. Seven Braconidae species were collected, distributed among Opiinae: Doryctobracon areolatus (Szépligeti, 1911), Utetes anastrephae (Viereck, 1913), and Opius sp., and Alysiinae: Asobara anastrephae (Muesebeck, 1958), Phaenocarpa pericarpa Wharton and Carrejo, 1999, Idiasta delicata Papp, 1969, and Asobara sp. Parasitism rates by braconids and figitids are presented. Doryctobracon areolatus was the most frequent, parasitizing the highest number of fly species, and showing the highest parasitism percentage in larvae feeding on Micropholis williamii fruits. The collected figitids belong to Aganaspis nordlanderi Wharton, 1998 and A. pelleranoi (Brethes, 1924). All 15 tritrophic associations are new records for the Brazilian Amazon region. The RFAD is an important natural reservoir of frugivorous larvae parasitoids.

Information concerning the presence of stink bugs in blackberry (Rubus spp.) in Brazil is sparse. This study aimed to identify the stink bug species associated with blackberry, to establish the daily dynamics and evaluate the fruits damage. The experiment was conducted in Santa Maria, Rio Grande do Sul State, Brazil, in blackberry orchard. Presence and evaluations of stink bugs were done weekly through visual and sweeping samplings at different day times. Five species of pentatomids were identified: Piezodorus guildinii, Nezara viridula, Euschistus heros, Dichelops furcatus and Edessa meditabunda. The bugs attack the drupelets producing a dark brown spot and wrinkled berries.
