| Abojetivou-se avalair o efeito de inseticidas aplicados nas sementes (TS) e em pulverizações no sulco de semeadura (PS), na presença do coró-da-soja, Phyllopahaga cuyabana. Em um dos experimentos, constatou-se que TS com imidacloprid (42, 60 e 90 g/ha), fipronil (50 g/ha) e thiamethoxam (70 g/ha) proporcionaram rendimentos relativo de grãos (RRG) significativamente superiores ao verificado na testemunha o coró reduziu o stand em 43,3%, enquanto nos outros tratamentos o prejuízo variou de 1,3 a 13,3%. em outro experimento, o TS com fripronil (35 g/ha), thiamethoxam (98 g/ha), imidacloprid (84 g7ha) e thiodicarbe (420 g/ha) garantiram RRG significtivamente superiores aos verificados nas respectivas testemunhas. Clorpirifós (1.344 g/ha) e endossulfam (980... |

| To evaluate the effect of soil management systems on population of white grubs, (Phyllophaga cuyabana Moser), and on its damage in soybean, experiments were set up under no-tillage and conventional tillage (one disk plow, and a leveling disk harrow) areas. Primary tillage equipment, used in other soil management systems, such as moldboard plow, disk plow, chisel plow and heavy duty disk harrow were also tested. Fluctuation of P. cuyabana population and the extent of its damage to soybean was similar under no-tillage and conventional tillage systems. Results comparing a range of primary tillage equipment showed that it affected soil insect populations differently, depending on the time during the season in which tillage was executed. Larval mortality could... |

| La zona de piedemonte caqueteño (Colombia) forma parte de la región amazónica (3600 mm de precipitación anual, 260 m.s.n.m., 26 °C) y presenta un ambiente megadiverso y ecológicamente frágil cuyos suelos están siendo afectados de manera creciente por la ganadería de tipo extensivo. En el presente trabajo se hizo un monitoreo de la biología y abundancia de escarabajos edafícolas en fincas ganaderas con pasturas degradadas, localizadas en los municipios de San Vicente del Caguán, El Doncello, Belén de los Andaquíes, Albania y Valparaíso, del departamento del Caquetá. Para el estudio se hicieron muestreos de adultos utilizando trampas de luz y de larvas en cuadrantes de suelo en parcelas de pasturas y relictos de selva durante épocas seca y húmeda. Se... |

| Additions to the Staphylinidae fauna of the Netherlands 1 From a total of over 14.000 Staphylinidae, collected in The Netherlands and belonging to the Nationaal Natuurhistorisch Museum at Leiden, the more interesting species were selected for further faunistic study. These species were, according to the last available comprehensive data (Everts, 1922a) either known as rare, non-indigenous or, in one case, as common. This selection was completed by data from other museums, private collections and literature in which way an upto-date review of the occurrence and distribution of these Staphylinidae can be presented. As the data extend over a period of a century, where possible, an attempt has been made to assess changes in the faunistic status. Two species... |

| Additions to the Staphylinidae fauna of the Netherlands 2 Faunistic and ecological data on Dutch Staphylinidae are presented. Sepedophilus nigripennis (Stephens) is recorded for the Dutch fauna for the first time. Tachyporus abdominalis (Fabricius) and T. formosus (Matthews) must be deleted for the Dutch fauna; all previous records are based on incorrect determinations. Aanvullingen voor de Staphylinidenfauna van Nederland 2 Faunistische en ecologische gegevens van een groot aantal Nederlandse Staphylinidae worden gepresenteerd. Sepedophilus nigripennis (Stephens) wordt voor het eerst voor de Nederlandse fauna gemeld. Tachyporus abdominalis (Fabricius) en T. formosus (Matthews) moeten geschrapt worden voor de Nederlandse fauna; alle onderzochte... |

| The objective of this work was to evaluate arrestant and stimulant feeding effects on Diabrotica speciosa (Ger.), using cucurbitacin-content starch-based formulations prepared with varying starch sources, and adding potassium lignate. In a glass slide assay, the wash off resistance of formulations was compared. Potassium lignate did not improve wash off resistance. Lagenaria vulgaris L. powder, in which cucurbitacin B concentration was determined as 0.28%, was added to the most adhesive formulation. The resultant material was used in a two-choice assay in which leaves of common bean, Phaseolus vulgaris L., treated with concentrations of 2.5%, 5%, 10%, 15% and 20% were offered to insects together with untreated control leaves. Greater number of insects and... |

| The species Chrysolina quadrigemina (Suffrian) (Coleoptera: Chrysomelidae) is recorded for the first time in Argentina, this being also the first record of this genus in the country. Its host plant, Hypericum perforatum L. (Clusiaceae) is native from Asia, Europe and Africa, and has behaved as a strong invader in several countries of the world where the implementation of a biological control program was necessary. The only country in South America that implemented such a control was Chile, in 1953. The arrival of C. quadrigemina to southern Argentina is probably due to natural dispersion from Chile. This record increases the number of Chrysomelidae species in the country. |

| Tropaeolum majus L. (nasturtium) is a culture popularly known by its medicinal, ornamental and culinary utility. This work aimed to evaluate the interaction between Astylus variegatus (Germar 1824) (Coleoptera: Melyridae) and the nasturtium flowers associated to the weeks of flourishing, in order to conceive the floral mechanims used by the species to attract A. variegatus. The insects collection was achieved with an entomologic net by the sweeping method, during the weekly flowering, at two hours, from 7am to 5pm. The studies of floral biology were carried out in twenty flowers by the analysis of measures and the arrangement of the floral parts. The nasturtium flower offers pollen and nectar to the insect as a compensation. However, it was observed that... |
