Resumo O bicudo dos frutos da acerola, Anthonomus tomentosus (Faust, 1894) (Coleoptera: Curculionidae), é registrado pela primeira vez no Brasil. Amostras deste inseto foram coletadas em frutos de acerola, Malpighia emarginata D.C. (Malpighiaceae), em quatro municípios do Centro-Norte do Estado de Roraima, na Amazônia brasileira. Informações sobre as injúrias observadas nos frutos infestados por A. tomentosus, sua distribuição em Roraima e sugestões para o seu manejo são apresentadas.

Abstract The weevil of acerola fruits, Anthonomus tomentosus (Faust, 1894) (Coleoptera: Curculionidae), is recorded for the first time in Brazil. Samples of this insect were collected in fruits of acerola, Malpighia emarginata D.C. (Malpighiaceae), in four municipalities in the north-central region of Roraima State, in the Brazilian Amazon. Information about injuries observed in fruits infested with A. tomentosus, its distribution in Roraima, and suggestions for pest management are presented.

In this study different sampling techniques for Diplopoda in soil, tree trunks and canopies were applied in an integrated way in the northern region of the Pantanal of Mato Grosso, Brazil. This was done in order to assess the relationship within the fauna in each forest strata, as well as its richness and temporal distribution. In all these habitats there were a total of 1,354 diplopods, distributed in four taxonomic orders, with Polyxenida being predominant over Polydesmida, Spirostreptida and Spirobolida. The largest representation was found on the trunks of the Vochysia divergens (721 ind.), intercepted by tree photoecletors, whereas in the canopies sampling reached only 65 specimens. In the edaphic stratum 568 diplopods were captured, most with the use of the Winkler extractor, followed by pitfall traps and soil photoecletors. In spite of being an important group in these environments, both in terms of richness and diversity, this was less than has been observed in other Neotropical areas. However, due to seasonal changes in the Pantanal the existence of a relationship between the soil and the tree fauna was found as well as different survival strategies observed during the flood period. Regarding vertical distribution, the greatest richness and variety of taxonomic groups was found in the forest's edaphic environment demonstrating its association mainly with this forest stratum.

Descrição da larva e pupa da broca do mamoeiro Pseudopiazurus papayanus (Marshall) (Coleoptera, Curculionidae, Piazurini). Larvas, pupas e adultos de Pseudopiazurus papayanus (Marshall, 1922) estão associadas com Carica papaya Linnaeus, 1753 (Caricaceae). A larva de último instar e a pupa são descritas e ilustradas. O dimorfismo sexual observado no ultimo segmento abdominal das pupas, também é ilustrado.

Larvae, pupae and adults of the piazurine weevil Pseudopiazurus papayanus (Marshall, 1922) are associated with Carica papaya Linnaeus,1753 (Caricaceae). The larval and pupal stages are described and illustrated. The sexual differences in the last abdominal segments of the pupae are also illustrated.
