| A escassez de trabalhos a respeito de parasitóides de ovos de Spartocera dentiventris (Berg) motivou o presente estudo, que teve como objetivo registrar a existência de parasitóides de ovos deste coreídeo, bem como quantificar a mortalidade ocasionada por esses agentes em condições de campo. O estudo foi conduzido numa lavoura de fumo (cv. Virgínia, var. K-326) no município de Porto Alegre, RS. No período de dez/97 a fev/98, 20 posturas de S. dentiventris, de idade conhecida, permaneceram expostas a todas as causas de mortalidade por 13 dias. Constatou-se a ocorrência de duas espécies de parasitóides nos ovos de S. dentiventris: Gryon gallardoi (Brethes) (Hym.: Scelionidae) e Neorileya ashmeadi Crawford (Hym.: Eurytomidae). Do total de ovos observados... |

| Exemplares de Chinavia erythrocnemis (Berg) foram coletados em branquilho [Sebastiania commersoniana (Baill.) Smith & Downs] no Parque Estadual do Espinilho (Barra do Quaraí, RS) e criados em laboratório sob condições controladas em vagens verdes de feijão (Phaseolus vulgaris L.). Os ovos de C. erythrocnemis são semelhantes aos das demais espécies neotropicais do gênero e não permitem a identificação da espécie neste estágio. Possuem forma de barril, cório com superfície reticulada, castanho-clara, com 61 processos aero-micropilares em média. Cada postura possui em média 12 ovos, característica única entre as espécies de Chinavia, até o momento. Em todos os ínstares, as ninfas são predominantemente negras, com ápice das jugas e do clípeo, ápice dos... |

| The biology of nymphs and adults of the neotropical pentatomid, Dichelops melacanthus (Dallas), feeding on the natural foods, soybean, Glycine max (L.) Merrill immature pods, and corn, Zea mays L. immature seeds, and on an artificial dry diet, was studied in the laboratory. Nymph developmental time was shorter on the natural foods (ca. 21-22 days) than on the artificial diet (28 days), and most nymphs reached adulthood on the food plants (55% on soybean and 73% on corn) than on the artificial diet (40%). Fresh body weight at adult emergence was similar and higher for females raised as nymphs on the natural foods, compared to females from nymphs raised on the artificial diet; for males, weights were similar on all foods. Mean (female and male) survivorship... |

| Ghilianella beckeri n. sp. of Emesinae from Rondônia State, Brazil is described. The most similar species to G. beckeri sp. nov. is G. approximata (McAtee & Malloch 1925). Males of G . beckeri n. sp. can be separated from G. approximata because the latter has: (1) seventh tergite much shorter, slightly surpassing pygophore, and not wrinkled; (2), bifurcated medial posterior process of the pygophore; and (3) parameres without spines. Females of G. approximata can be distinguished from those of G . beckeri n. sp. since they have: (1) the expansions of the fifth abdominal tergum distinctly within lateral margins of disk; (2) the seventh tergite longer than wide; and (3) the eighth tergite semicircular and lightly carinate medially. |

| ABSTRACT Despite its important effect on the maintenance of tritrophic interactions among plants, insect herbivores, and ants, there is still a paucity of natural history and basic biology information involving trophobiosis among Heteroptera stink bugs. Here, based on previous observations of a new trophobiotic interaction between Edessa rufomarginata (De Geer, 1773) and Camponotus rufipes (Fabricius, 1775) ants, we describe the chemical profile of the honeydew obtained by Gas Chromatography–Mass Spectrometry. There were mainly three different sugars (trehalose, glucose, and sorbose) within our samples. The extrafloral nectaries of Caryocar brasiliense Camb., the host plant of E. rufomarginata, attracts a wide assemblage of Cerrado ants with varying... |

| Nymphal development of the predator Podisus nigrispinus (Dallas) fed with a susceptible (UFV 16) or an insect resistant soybean genotype (IAC 17) and with larvae of the prey Anticarsia gemmatalis Hübner (Lepidoptera, Noctuidae) reared on these genotypes, was evaluated. Survival and duration of each instar and of total nymphal stage, besides weight of nymphs at the beginning of each instar and of adults of P. nigrispinus soon after emergence, were also evaluated. Nymphal survival of this predator was similar with both genotypes (64.41% for the UFV 16 and 72.88% for the IAC 17). Duration of second and fourth instars for nymphs that originated females, of fourth instar for those that originated males, of the nymphal period for males (20.21 and 17.94 days) and... |

| With the intention of contributing to the knowledge of the biodiversity in the protected areas of Argentina, terrestrial Heteroptera were collected in the Natural Reserve of the Iberá. The sampling site was the locality of Colonia Carlos Pellegrini (28° 32'S 57° 09'W) and the following collection methods were used: sweeping, beating, fogging and light-trapping. A list is presented, with 90 species belonging to the superfamilies Reduvioidea (Reduviidae), Mirioidea (Miridae), and Lygaeoidea (Berytidae, Colobathristidae, Cymidae, Lygaeidae, Blissidae, Geocoridae, Pachygrontidae and Rhyparochromidae), 13 of them are new records for the Argentine Republic (Debilia fusciventris, Sindala granuligera, Pnirontis (Centromelus) tabida, Cymoninus notabilis, Ochrimnus... |

| Some biological, morphological and behavioral aspects of adults Podisus sculptus Distant, 1889 (Heteroptera, Pentatomidae) fed with Bombyx mori Linnaeus, 1758 (Lepidoptera, Bombycidae) (fourth and fifth instar caterpillars) and Tenebrio molilor Linnaeus, 1758 (Coleoptera, Tenebrionidae) (third and fourth instar caterpillars) were studied and no differences were found between these two preys. Average values for the parameters studied were: period of pre-oviposition (6.14 days), oviposition (8.57 days) and pos-oviposition (3.57 days); number of eggs/female (97.71); number of postures/female (3.96); female weight (68.90mg) and male weight (47.43mg). Podisus sculptus has brownish color, and four yellow spots in the scutelum: one close to the head and three... |

| The genus Tibraca Stål, 1860 is revised, and some taxonomic changes are introduced. The following species are considered to belong in this genus: Tibraca limbaliventris Stål, 1860, T. similima Barber, 1941, and T. exigua sp.n. (from Argentina). Three other species, formerly placed in Tibraca, are considered respectively: T. obscurata Bergroth, 1914, incertae sedis; Mecocephala fusca (Haglund, 1868), comb.n.; Ogmocoris hypomelas (Burmeister, 1835). The genus Ogmocoris Mayr, 1864 is reinstated. |
