| Frankliniella occidentalis (Pergande) é uma das principais pragas associadas à cultura do morangueiro no Sul do Brasil. O ataque do inseto à cultura resulta no murchamento de flores e bronzeamento de frutos. Neste trabalho, foi estimada a temperatura base e as exigências térmicas das fases de ovo, larva e pupa de F. occidentalis em morangueiro. Os insetos foram criados em folíolos da planta nas temperaturas de 16, 19, 22, 25, 28 e 31°C, em câmaras climatizadas (70 ± 10% U.R.; fotofase de 12h). O número de gerações anuais que F. occidentalis completa foi estimado para seis regiões produtoras de morango no Rio Grande do Sul (RS), com base nas exigências térmicas da espécie. A velocidade de desenvolvimento de F. occidentalis aumentou com a elevação da... |

| The order Thysanoptera comprises mostly phytophagous or fungivorous species, with a few species that are predators. Recent studies have emphasized the diversity of behavioural patterns amongst these diminutive insects. From the 5,500 species known worldwide, about 10% are recorded from Brazil, mostly tropical areas. In this work we surveyed the Thysanoptera fauna of a southern locality, 800 km south of the Tropic of Capricorn. The study site was ''Parque Estadual de Itapuã'' (30°22'S 51°02'W), Viamão, RS, and thrips were sampled from wild flowers, branches, grass and litter, from June 1999 to May 2001. A total of 83 species in 32 genera was found, but only 29 of these species could be identified, emphasizing the poor knowledge of the insect fauna of... |

| Seeking to identify thrips species associated to peach and the injuries they cause, plants of Aurora and Tropic Beauty cultivars were weekly monitored, from May to August of 2005, in Holambra II district, in Paranapanema, SP. Flowers and fruits from six plants per hectare were sampled by the hitting technique. Frankliniella occidentalis (Pergande), F. schultzei (Trybom), F. gardenia (Moulton), F. condei John, F. insularis (Franklin) and Thrips tabaci Lindeman, in Thripidae, and Haplothrips gowdeyi (Franklin), in Phlaeothripidae were identified. F. occidentalis was dominant, comprising 55.7% of the total specimens sampled. Slight and severe injuries were registered in fruits. |
