| In the time period between May/92 to Abril/93, 602 (267 males and 335 females) specimens oi P. brasiliensis Latreille, 1817 were collected. The shrimps were captured by night using a hand net in áreas between 30 to 150 cm deep. The amplitude of length ranged from 1,3 to 13,7 cm, the highest frequencies of capture were registered during the Fali between the classes of 7,0 and 10,0 cm. The males present isometric growth and the females negative allometric one. The size of the pre-adult ranged from 8,8 cm for the females and 9,2 cm for the males. The recruiting occurs chiefly in the Summer with intense growth during the Fall-Winter period, reaching a climax with the migration of pre-adults to the ocean in midwinter. |

| A cultura do tomate na Serra da Ibiapaba, no Estado do Ceará, é considerada uma das atividades agrícolas mais importantes e geradora de divisas para esta região. Entretanto, apresenta como uma das pragas chave a broca pequena, Neoleucinodes elegantalis (Guen.) (Lepidoptera: Pyralidae). Essa praga ocorre geralmente em elevadas infestações, ocasionando danos à produção em até 90%, pela destruição e apodrecimento dos frutos, levando os produtores a realizarem até duas pulverizações por semana. Sua ocorrência foi constatada no Brasil, em 1922, no Ceará, e em 1939, em São Paulo, encontrando-se atualmente disseminada em quase todas as regiões produtoras de tomate do Brasil. Na região Nordeste, a sua ocorrência é generalizada, exceto no Submédio do Vale do São... |

| The emergence and pupal mortality factors of Anastrepha obliqua (Macq.) (Diptera: Tephritidae) along the fruiting season of the host plant, Spondias dulcis L. (Anarcadiaceae), were studied in Sertãozinho, SP, Brazil, under field and laboratory conditions. Eclosed and uneclosed puparia were recorded in two experimental conditions. The number of emerged flies and parasitoids were determined in the eclosed puparia. The uneclosed puparia were inspected and classified into living (dormant) and dead. The following pupal mortality factors were considered: disease, desiccation, predation and parasitism. Out of the total of 1,204 puparia analyzed, 53% emerged and 47% remained uneclosed. Out of the uneclosed puparia, 25.3% contained dormant pupae and 21.7% showed no... |

| We tested the functional response of the phytoseiid predator Phytoseiulus macropilis (Banks, 1904) to different population densities of Tetranychus urticae Koch, 1836 (the two-spotted spider mite - TSSM) in the laboratory. We evaluated the curve that best fits the data obtained, based on the reduced X². The predators were obtained from leaves of Oso Grande strawberries at the municipality of Bom Princípio, state of Rio Grande do Sul, Brazil. Fifteen seemingly healthy females of P. macropilis were randomly chosen and individualized in each of the arenas with different TSSM densities. The following prey densities were tested: 1, 2, 3, 5, 10, 20, 30, 35, 45, 55, 70 and 125 females. The tests were performed in a germination chamber with photoperiod of 12 hours... |

| A year-long beach seine survey at the continental margin of Sepetiba Bay, Rio de Janeiro State, Brazil, catching mainly young-of-the-year and juvenile fishes was carried out from July 1983 to June 1984, in order to describe the community structure and their spatial and seasonal variations. Fifty-five monthly samplied carried out in five sites in the marginal surf zone waters yielded 11,463 fishes in 82 species, 59 genera and 31 families. Gerreidae, Engraulidi-dae, Atherinidae and Ariidae families amounted 87.01% of the total catch in number, and 81% in weight. Cerres aprion Cuvier, 1829, Anchoa januaria (Steindachner, 1879), Anchoviella lepidentostole (Fowler, 1911), Atherinella brasiliensis (Quoy & Gaimard, 1824) and Neluma barba (Lacépède, 1803)... |
