    Martins, Sidnei Terezinha S; D'Incao, Fernando

    Abstract in English:

    Twelve species of Pinnotheridae from Santa Catarina and Rio Grande do Sul States, Brazil, are redeseribed and illustrated; a key of identification is presented. Clypeasterophilus stebbingi Rathbun, 1918; Pinnotheres garthi Fenucci, 1975 and Pinnixa brevipollex Rathbun, 1898 are reported for the first time for Brazil. Clypeaslerophilus stebbingi Rathbun, 1918 and Tumidotheres maculatus Say, 1818, are new record for Santa Catarina. Fabia insularis Melo, I971 and Pinnotheres emiliai Melo, 1971 are revalitaded; Fabia sebastianensis Rodrigues da Costa, 1969; Pinnotheres garthi Fenucci, 1975; Pinnotheres emiliai Melo, 1971 and Pinnixa patagoniensis Rathbun, 1918 are new records for Rio Grande do Sul.

  • Stimulation of spermiation with hormonal injections in the curimbatá Prochilodus scrofa (Steindachner) (Ostheichthyes, Characiformes, Prochilodontidae)

    Kavamoto, Emico T; Ferraz, Eduardo de M; Talmelli, Elaine F. de Andrade; Mainardes-Pinto, Cleide S.R; Romagosa, Elizabeth; Narahara, Massuka Y; Barnabe, Valquiria H; Campos, Benedicto do E.S. de

    Abstract in English:

    Sperm of 180 three year old males of curimbatá, Prochilodus scrofa (Steindachner, 1881), was collected to verify the possibility of utilization of these males more than one time, and to know how long after the hormonal induction would occur the highest production of milt. This experiment was carried out in 1991 and 1992. After sperm was collected, each male was stimulated by the first injection of five IU/g of hCG. Then, milt was collected at 8, 16, 24, 48, 72 and 96 hours before and after the first dose and at 16 hours before and after the second one. Mean volume values were, before hormonal injection, 0.22ml and after two doses of hCG, 106ml. Maximal production occurred between 16 and 24 hours after induction. Mean values of sperm concentration and total number of sperm were, before hormonal induction, 31.16xl0(6)/mm³ and 6.79x10(9) and after two doses, 21.46x10(6)/mm³ and 22.15x10(9), respectively. There were no statistical differences between males receiving two or one doses of hCG concerning fertilization. Results indicated that males of Prochilodus scrofa may be induced a second time 14 days apart, what increases their reproduetive efficiency.
  • Aspects of distribution of Pantopoda on Sargassum from Itanhaém and Ubatuba, São Paulo, Brazil

    Varoli, Franci Mary Fantinato

    Abstract in English:

    Qualitative and quantitative aspects of the distribution of Pantopoda species living on Sargassum of Ubatuba and Itanhaém (northern and southern coast at São Paulo State, respectively) were studied. The results showed the occunence of nine Pantopoda species. The highest relative frequency was assigned to Tanystylum isahellae Marcus, 1940. In general the density of Pantopoda species was related to that of Hydrozoa covering Sargassum.
  • Morphological variations of the stage growth of the amphipods Amphilocus neapolitanus Della Valle (Gammaridea, Amphilochidae) and Ampithoe ramondi Audouin (Gammaridea, Amphithoidae) from the algae Sargassum cymosum

    Leite, Fosca P.P

    Abstract in English:

    A descriptive account is given of the post-embrionic development of Amphilochus neapolitanus Della Valle, 1893 and Ampilhoe ramondi Audouin, 1826 living on Sargassum cymosum C. Agardh, 1820 of Ubatuba, Brazil (23º30'S-45º06'W) through the growth stage based on the morphological changes at each moult. The growth stages are described on the increase of antennal and pleopodal articles number and morphological alterations of gnathopods. The number of stages was found to be different for males and females and the maturity occurs after 6 and 5 post marsupial stages for A. neapolitanus and A. ramondi respectively.

  • Gas vacuoles and flotation in Diffugia mitriformis Wallich (Protista, Rhizopoda, Testaceolobosea)

    Torres, Vladimir Stolzenberg

    Abstract in English:

    The natural formation of gas vacuoles as a method of locomotion is described for Difflugia mitriformis Wallich, 1984. These vacuoles may contain different compositions of gases, basicly carbodioxyde or oxigen, with a membranous limitation similar or identical to other types of vacuoles. Those vacuoles are utilised by the organism as a mode of dislocation frorn the bottom to the water surface by flotation permiting better conditions for the survival of the individual, with the consequence of the perpetuance of the taxon.

  • Field diet of the grasshopper Abracris dilecta Walker (Orthoptera, Acrididae)

    Sperber, Carlos Frankl

    Abstract in English:

    Abracris dilecta Walker, 1870 (Orthoptera, Acrididae, Ommatolampinae) ate leafs of at least 14 plant species, in the families Asteraceae, Lamiaceae, Malvales (Sterculiaceae, Tiliaceae or Malvaceae), Poaceae, Fabaceae, Verbenaceae, Aristolochiaceae, Rubiaceae and Melastomataccae. Elephantopus mollis H.B.K. (Asteraceae) and Hyptis suaveolens Poit. (Lamiaceae) comprised 50% of the diet. The diet breadth of A. dilecta was compared to that of other 11 grasshopper species of the same sub-family, with rarefaction curves. The number of plant species eaten by A. dilecta was greater than that of nine other grasshopper species of the same sub-family (Rhachicreagra spp.) but was lower then two others (Microptylopteryx hebardi Rehn, 1905 and Rhachicreagra astytophallus Jago & Rowell, 1981). This results are discussed in view of the broad geographical range and possession of developed wings by A. dilecta, which contrasts with most Ommatolampinae grasshoppers.

  • Feeding behavior and diet of the Oxyrhopus guibei Hoge & Romano (Serpentes, Colubridae)

    Andrade, Rogério de Oliveira; Silvano, Renato A. Matias

    Abstract in English:

    The feeding behavior and constriction pattern of adults and juveniles Oxyrhopus guibei Hoge & Romano, 1978 preying on rodents and lizards are described. An analysis of stomach contents of snakes preserved in collections was made to study its diet. The results indicate that this snake constricts prey with right to left side movements, horizontal position and with the dorsal portion of its body. Rodents were constricted by adult snakes whereas lizard were swallowed alive. The diet is composed of lizards and rodents, with an ontogenetic shift from lizards to rodents.

    Nascimento, Eduardo Cândido do; Zanuncio, José Cola; Menin, Eliane; Ferreira, Paulo Sérgio Fikza

    Abstract in English:

    Some biological, morphological and behavioral aspects of adults Podisus sculptus Distant, 1889 (Heteroptera, Pentatomidae) fed with Bombyx mori Linnaeus, 1758 (Lepidoptera, Bombycidae) (fourth and fifth instar caterpillars) and Tenebrio molilor Linnaeus, 1758 (Coleoptera, Tenebrionidae) (third and fourth instar caterpillars) were studied and no differences were found between these two preys. Average values for the parameters studied were: period of pre-oviposition (6.14 days), oviposition (8.57 days) and pos-oviposition (3.57 days); number of eggs/female (97.71); number of postures/female (3.96); female weight (68.90mg) and male weight (47.43mg). Podisus sculptus has brownish color, and four yellow spots in the scutelum: one close to the head and three across the elitra near the pronotum. Matings were more frequent between 15 and 19 hours and the male search for the female which showed movements of antennae. This insect showed cannibalism only in high population density and shortage of food.

    Zanuncio, Teresinha V; Zanuncio, José C; Saavedra, Jorge L.D; Lopes, Emerson D

    Abstract in English:

    Nymphs of Podisus nigrispinus (Dallas, 1851) were fed with Zophobas confusa Gebien, 1906, Tenebrio molitor Linnaeus, 1758 (Coleoptera, Tenebrionidae) and Musca domestica Linnaeus, 1758 (Diptera, Muscidae) under 25±0.5ºC, 60±10% of RH and photophase of 12h. Nymphal viability of P. nigrispinus were 64.0%, 80.0% and 92.0% with Z. confusa, M. domestica and T. molitor, respectively. No differences were found for pre-oviposition period, number of egg masses, number of eggs, egg viability, and longevity for females of this predator fed with any of these preys.

The maturacion sexual stadium were measured (cm) and weightied (g). Expression of relation among weight of body (wt) and width of carapace (wid) was Wt=0,0567 Wid3,0494 on males and wt=0,074 Wid2,8795 on females. The relation length (Lt) width (wid) of carapace was Lt=0,4322. wid on males and Lt=0,4578. wid on females.
