The expansion of Conocephalus discolor in the southern part of the province of Limburg (Orthoptera: Tettigoniidae) The range of Conocephalus discolor (Thunberg, 1815) in northwestern Europe and Britain has expanded substantially during the last decades. The species is known from the Netherlands since 1990 but was not found in the southern part of the province of Limburg until 1997. In 1997, triggered by an accidental find of a population in his neighbourhood, the author became highly interested and started investigating the distribution of C. discolor in these surroundings. The localities both where the species has been observed and those where it not has been found, are mapped. It became clear that the species is common between Kerkrade and Geleen. This... |

1. Inleiding In de serie verspreidingsatlassen van de Nederlandse Aculeate vliesvleugeligen ligt nu die van de spinnendoders (Pompilidae) voor U. Eerder zijn er een atlas van 64 soorten graafwespen (Lefeber, 1979) en een van de niet parasitaire Megachilidae (Van der Zanden, 1982) gepubliceerd. Atlassen van de overige graafwespen zijn in voorbereiding. Spinnendoders zijn in Nederland meestal geheel zwart gekleurd of zwart met een gedeeltelijk rood achterlijf. Ze leven op zandige terreinen, aan bosranden, in moerassen, in wegbermen e.d. De meeste soorten zijn minder dan een centimeter groot en leven vrij onopvallend vlak bij de grond, waar zij zich vooral bezighouden met het vangen en verslepen van spinnen. Dit boek behandelt vooral de verspreiding van de... |

Systematiek De indeling van de Orthocladiinae levert zo mogelijk nog meer problemen op dan die van de andere subfamilies van de Chironomidae. Momenteel is het algemeen gebruikelijk de groep in vier subfamilies te splitsen: Diamesinae, Prodiamesinae, Orthocladiinae en Telmatogetoninae (zie bijv. Saether, 1979a; Ferrarese & Rossaro, 1981; Cranston, 1982). In oudere literatuur worden deze subfamilies vaak niet onderscheiden of wordt een andere indeling gemaakt (Brundin, 1956; Pankratova, 1970; Fittkau & Reiss, 1978). De Telmatogetoninae leven uitsluitend marien en zullen hier buiten beschouwing blijven. De verschillen tussen de larven van de overige subfamilies zijn voor een determineerwerk onpraktisch. Zo is het belangrijkste kenmerk van de... |

This first part of 'The larvae of the Dutch Chironomidae' deals with the larvae of Tanypodinae and Chironomini. In chapter I an introduction is given to sampling and handling of chironomid larvae. In chapter II their general morphology and development are described, followed by a key to the subfamilies (p. 25). The key for larvae of Tanypodinae (p. 34) in many cases leads to species level . For the Chironomini the first key (p. 103) leads to a genus or species group, but sometimes a further key (with description of the genus) enables identification of the species. For every taxon the fourth instar larva is described and the most important data on life cycle and ecology are given. When using this book in other countries one should be aware of the possible... |

Constatou-se parasitismo em amostras de ovos de cigarrinhas-das-pastagens coletadas em pastagens de Brachiaria decumbens, pelo microhimenóptero Anagrus urichi Pickles, constituindo-se no primeiro registro dessa natureza para o Estado de Mato Grosso do Sul. O índice de parasitismo observado foi de 10,4%, sendo que, em média, emergiram 4,7 parasitóides por ovo. A exposição de 100 ovos da cigarrinha Notozulia entreriana (Berg), obtidos em laboratório, a oito desses parasitóides, resultou em 13% de parasitismo, indicando a possibilidade de multiplicação desse inimigo natural em laboratório. |

O afídeo Sipha flava (Forbes) ocasiona injúrias em capim-elefante e sua biologia é pouco conhecida. O objetivo deste trabalho foi avaliar o efeito da temperatura no desenvolvimento, sobrevivência e reprodução de S. flava alimentada com Pennisetum purpureum. Ninfas com até 12h de idade foram individualizadas sobre seções foliares de capim-elefante e mantidas em condições controladas (12, 16, 20, 24, 28 e 32ºC ± 1ºC, UR 70 ± 10% e fotofase de 12h). O total de 150 ninfas foi usado por tratamento, divididas em 30 repetições, em delineamento inteiramente casualizado. A temperatura base (Tb) foi de 0,83, 1,05, 3,01 e 4,98 para ninfas de primeiro, segundo, terceiro e quarto ínstares, respectivamente, indicando exigências térmicas distintas para os diferentes... |

The objective of this work was to evaluate the effect of calcium silicate (CaSiO3) and of the activator acibenzolar-S-methyl (BTH) on resistance induction in cucumber, against the whitefly Bemisia tabaci (Gennadius) biotype B. Antibiosis, free-choice and no-choice preference tests were conducted in a greenhouse and at laboratory of the, Departamento de Entomologia of the Universidade Federal de Lavras (UFLA), MG, Brazil. The design was completely randomized, with the following treatments: 1) control; 2) application of 3 g calcium silicate.kg-1 of substrate; 3) two 200ml applications of 1% calcium silicate solution per pot; 4) two 100ml applications of 0.005% BTH solution per pot; and 5) application of calcium silicate and BTH at the rates used for... |

A integração entre plantas resistentes e agentes de controle biológico pode ser uma alternativa viável para o manejo do pulgão-verde, Schizaphis graminum (Rondani), na cultura do sorgo. Experimentos foram conduzidos com a finalidade de avaliar o efeito de quatro genótipos de sorgo: GR 11111 e TX 430 x GR 111 (resistentes), GB 3B (moderadamente resistente), e BR 007B (suscetível), sobre o controle biológico do pulgão S. graminum realizado pelo predador Chrysoperla externa (Hagen). Para isso, avaliaram-se diferentes níveis de infestação de S. graminum, na presença e ausência do predador, em casa-de-vegetação e a viabilidade de controle de S. graminum no campo. O efeito do predador foi notado 25 dias após a infestação, proporcionando maior crescimento das... |

This is the first record on the invasion of the Neotropical brown stink bug, Euschistus heros (F.) in Paraná County (latitude 31º 51' 9.6" S, longitude 60º 32' 11.2" W), Entre Ríos province, Argentina. Five adults were intercepted in 2009/2010, one in crop residues and four on soybean fields. The expanding range in the distribution of E. heros in the Southern Hemisphere is believed to be due to the increased commercial trade among countries, increase in the area cultivated with soybean, and the adoption of no-tillage cropping systems. |
