ABSTRACT
O objetivo do presente trabalho foi identificar os nematoides associados a plantas de antúrio (Anthurium andraeanum) cultivadas como flor de corte (13 amostras) ou plantas em vaso (41 amostras) nos estados de São Paulo, Paraná e Santa Catarina. Nematoides foram extraídos de 10g de raízes e 250cm3 de solo ou substrato e identificados sob microscópio de luz. A espécie mais frequente foi Radopholus similis, detectada em 54% das amostras de antúrio cultivado como flor de corte. Constituíram novas ocorrências em antúrio no Brasil: Helicotylenchus erythrinae, H. californicus, H. multicinctus, Meloidogyne paranaensis e R. similis. Entretanto, nenhum nematoide parasito de plantas foi encontrado nos antúrios cultivados em vaso, com substrato de fibra de coco. .
The aim of this research was to identify plant parasitic nematodes associated with Anthurium andraeanum plants cultivated as cut flowers (13 samples) or pot flowers (41 samples) in the States of São Paulo, Paraná and Santa Catarina, Brazil. Nematodes were extracted from 10g of roots and 250cm3 of soil by centrifugation method and identified under microscope. The most frequently occurring species was Radopholus similis detected on 54% of anthuriums cultivated as cut flowers. Among the identified species, the following associations constitute new records to Brazil in anthuriums: Helicotylenchus erythrinae, H. californicus, H. multicinctus, Meloidogyne paranaensis and R. similis. However, no plant parasitic nematodes were detected on A. andraeanum cultivated as pot flowers in coconut fiber substrate. .
ABSTRACT
This study reports the first occurrence of Muscidifurax raptorellus (Hymenoptera: Pteromalidae) in Brazil. Chicken manure samples, collected at two-week interval, were taken to the laboratory and the pupae were extracted by the method of flotation. Each pupa was placed in capsules of colorless gelatin until the emergence of dipterous or their parasitoids. In the study, ten pupae of Fannia pusio (Wiedemann, 1830) (Diptera: Fanniidae) were obtained, two of which yielded the parasitoid M. raptorellus . The percentage of parasitism was 5.0 percent.

This study reports, for the first time, the occurrence of Eurytoma sp. (Hymenoptera: Pteromalidae) as parasitoid of Fannia pusio (Wiedemann) (Diptera: Fanniidae) found in chicken dung in Itumbiara, Goiás, Brazil. Manure samples, collected at two weeks intervals, were taken to the laboratory and the pupae were extracted by water flotation. Each pupa was placed in capsules of colorless gelatin until the emergence of dipterous or their parasitoids. The parasitism was 1.3 percent
