| The insects oviposition behavior is fundamental to study population dynamics, life history evolution, insect-plant and parasitoid-host interactions. Zabrotes subfasciatus (Boheman, 1833) females oviposition behavior in the presence and absence of a host is unknown. The main objective of this study was to describe in detail the oviposition behavior of host deprived or non-deprived females, and observe how the several situations of deprivation (days without host) influence oviposition. Six groups were assembled, three deprived of the host (for 2, 5 and 8 days) and three control groups (with host), each containing one newly-emerged couple (0-24h) of wild Z. subfasciatus, The non-deprived (control) groups received the hosts every day (5 bean seeds Phaseolus... |

| Senna multijuga Rich. I. & B. (Caesalpinaceae) é uma espécie ornamental, comum no Sudeste do Brasil. A fim de verificar os danos causados por bruquíneos às sementes dessa planta, foram coletados frutos de 31 de março a 30 de maio de 2000. Os frutos foram acondicionados em casa de vegetação até a emergência dos insetos, que foram posteriormente identificados. Das amostras emergiram 67% de Sennius crudelis Ribeiro-Costa & Reynaud, 20% de Sennius puncticollis (Fåhraeus) e < 1% de Sennius nappi Ribeiro-Costa & Reynaud. Das sementes analisadas, 62% foram sadias, 26% chochas e 12% danificadas. O percentual de sementes chochas e danificadas foi de 38%. Considerando que outros fatores diminuem a germinação das sementes, como patógenos e... |

| The objective of this work was to characterize the resistance of 50 cowpea (Vigna unguiculata) genotypes to Callosobruchus maculatus. A completely randomized design with five replicates per treatment (genotype) was used. No-choice tests were performed using the 50 cowpea genotypes to evaluate the preference for oviposition and the development of the weevil. The genotypes IT85 F-2687, MN05-841 B-49, MNC99-508-1, MNC99-510-8, TVu 1593, Canapuzinho-1-2, and Sanzi Sambili show non-preference-type resistance (oviposition and feeding). IT81 D-1045 Ereto and IT81 D-1045 Enramador exhibit antibiosis against C. maculatus and descend from resistant genitors, which grants them potential to be used in future crossings to obtain cowpea varieties with higher levels of... |

| ABSTRACT Forest species can have their seeds damaged by granivorous insects, especially by those in their larval stage. In this context, this study aims to report the occurrence of Amblycerus species in Cordia trichotoma seeds, to describe their main damage to seeds and effects on germination, as well as their associated hymenopteran parasitoids. Therefore, seven trees were selected in the municipality of Taquaruçu do Sul, RS, Brazil. Fruits were collected weekly from the medium third of the tree crown, from the beginning of their formation until total dehiscence. To examine the damage caused by granivorous insects within the fruits, 15 fruits from each tree were sectioned with a scalpel. Furthermore, 10 fruits from each tree were stored individually in... |

| Abstract Pair-wise competition produces asymmetric consequences for the interacting species, resulting in reduction of species fitness at the individual scale; however, little is known of the effects of competition on the allometric patterns of insects. In this study, we explored how competition, by means of pod infestation, affects the development of female and male individuals in the co-occurring bruchine beetles Merobruchus terani and Stator maculatopygus. We found differences between M. terani and S. maculatopygus in all morphometric traits, but no significant differences between males and females in either species. We also found, with an increasing degree of pod infestation, a positive trend in the pronotum, elytron and body weight of M. terani and a... |

| Senna multijuga (Rich.) H. S. Irwin & Barneby (Caesalpinaceae) é uma planta ornamental comum no sudeste do Brasil, suscetível ao dano por bruquíneos predadores de sementes. Com o objetivo de identificar os predadores de suas sementes e determinar seus ciclos populacionais, frutos de cinco árvores foram coletados em 2000 e 2001 e acondicionados em casa de vegetação até a emergência de adultos. Os bruquíneos foram identificados como Sennius crudelis Ribeiro-Costa & Reynaud, 1998, S. puncticollis (Fåhraeus, 1839) e S. nappi Ribeiro-Costa & Reynaud, 1998. Sennius crudelis foi a espécie mais abundante em 2000, seguida por S. puncticollis e S. nappi. Em 2001, Sennius crudelis foi seguida por S. nappi e S. puncticollis. Diferenças foram... |
