Aspects of reproduction of Rineloricaria latirostris Boulenger, 1899 of Passa Cinco river (Ipeúna, São Paulo) were investigated during 18 months. The spawing period was determined by the analysis of the maturation curve, based of the monthly variation of the gonadosomatic index and condition factor. The size and age on the maturation and fecundity were also determined. The fecundity was realted to some parameters such as total length and total weight.Abstract in English:

This work deals with feeding tests performed in laboratory with Pantopoda species, Tanystylum isabellae Marcus, 1940 and Anoplodactylus stictus Marcus, 1940. Animals (alive and dead) and vegetable foods were offered to males without eggs, males with eggs, females and juveniles Pantopoda. Of the 13 types of food offered to the animals only Sertularia Linnaeus, 1758 (Hydrozoa). Amathia distans Busk, 1886 (Bryozoa), Hyale media (Dana, 1853) (Crustacea, Gammaridea), Caprella danilevskii Czerniavski, 1868 (Crustacea-Caprellidae), Artemia salina Leach, 1812 (Crustacea, Anostraca) e Perna perna (Linné, 1758) (Bivalvia, Mytilidae) were actually eaten. The macroalgae Sargassum C. Agardh, 1820; Padina Adanson, 1763; Chaetomorpha Kützing, 1845 and Ulva Linnaeus. 1753, the Hydrozoa Dynamena (Linnaeus, 1758), Polychaeta aixl anemon fragments weren't accepted.Abstract in English:
Skin to lung migration of Schistosoma mansoni Sambon, 1907 - (75 Se) - selenomethionine-labeled cercariae was tracked by tissue autoradiography on days 1, 4, 6, 8 after challenge, in rabbits immunized with a S. mansoni derived saline extract. Either in vaccinated animals or in those of the control unprimed group, the peak of skin schistosomula occurs 24hs after infection. Comparison between peaks of lungs migrating larvae showed that, in control animals, the increase of worm burden in this site, is detected on the 6th day post-infection, differing from immunized rabbits, in which this peak occurs on day 4, when skin and lungs counts are still equivalent, decreasing gradually, showing a different pattern of the S. mansoni migration and suggesting that main parasite attrition occurs during the late skin and early lung phases in the immunized group.Abstract in English:
Myrciariamyia bivalva, gcn.n., sp.n. associated with Myrciaria Jloriburula (Myrtaceae), in Brazil, is deseribed and illustraled (larva, pupa, male, female and gall).Abstract in English:
At Guaraluba bay, the catfish Genidens genidens shows incubating behavior during the summer months. The larvae are either less or heavier than the eggs, and their stomach analysis confirms the exogenous leeding during incubation. Embryos sizes can increase to 59mm in total lenght and 2,8g in total weight, including the yolksac. It was observed that the largest larvae are guarded by the largest adults, and that the embryo size is similar among individuals from the same adult.Abstract in English:
In this paper, female Macrobrachium carcinus (Linnaeus, 1758) maturation curve, weight/length relationship, length and weight growth curves were studied. Prawns were captured, by traps, in Ribeira de Iguape river (24ºS and 47ºW), southern Brazil. There were used 207 females. It was observed that M. carcinus presents several spawnings during its life cycle and reproductive period goes on, at least till six years old. Weight/length relationship can be represented for the equation W = 8.73 E-3 L3.28. Expressions obtained for length and weight growth curves are Lt = 21 .0 (1-e-0493t) and Wt= 190 (1-e-0493t)3.28. respectively. A symptotic maximum length and asymptotic maximum weight are nearly attained at six and eight years old, respectively.Abstract in English:
The influence of a diet based on putrid horse meat over the post-embryonic development of Cochliomyia macellaria (Fabricius, 1775) under controlled conditions (UR 65 10% and 14 hours of photophase) was compared with the results obtained using a meat broth diet to which other sources of animal and vegetable protein were added. The flies were maintained at 30ºC, from egg until mature larvae spontaneously abandoned the diet. They were then transfered to a climatized chamber at 27ºC. The larvae and pupae viability and the weight of the mature larvae were significantly inferior, when a diet based on meat broth was used, even though the larvae period was significantly increased with this diet. This type of diet did not charge the time of development of the pupae. The inoculation of the egg mass directly over the diet was recommend, instead of the technique in which the egg masses are transfered to humid filter paper, followed by the handling of the recently ecloded larvae.Abstract in English:
Plagiorchis vicentei, sp.n. is described from the small intestine of the lizard, Hemidactylus mabouia (Moreau de Jonnès, 1818), from Teresópolis, Rio de Janeiro, Brasil. The new species differs from P. didelphidis (Parona, 1896) by the smaller size of body, by the presence of spinous tegument and ventral sucker smaller than oral sucker; from P. parumbursaitus Freitas & Dobbin Jr., 1961 by the smaller size of body and suckers and the bigger size of eggs; from P. rangeli Artigas & Zerpa, 1961 by the bigger size of suckers and eggs; and front P. freitasi Vicente, 1978 by the smaller size of body, by the bigger size of eggs and by the different position of gonads that in the new species are close to the ventral sucker.Abstract in English:
Neurosecretory cells of the nervous system of third-instar larvae of Anastrepha obliqua Macquart, 1835 were located and described histomorphologically. Six groups of neurosecretory cells were identified in the brain and one group in the ventral ganglion. The groups differed in position, cell size and staining characteristics. Four of these groups appear to he active throughout the third instar and three, from the prepupal period.Abstract in English:

Qualilative and quantitative studies of Isopoda species were made at Mundaú/Manguaba Estuary-Lagoon Complex on the Coast of Alagoas State. Six points were established in order to carry out methodical collections of animals. These collections were made monthly, without interruption, from April, 1990 to March, 1991, in which three families, five genera and seven species of Isopoda were identified. A special key for identification of Isopoda and also diagnosis for each species are presented. Sphaeromatidae Family was the most significant and Cassidinidea fluminensis (Mane-Garzón, 1944), was the species with numerical dominance. Space/time distribution of the species of Isopoda was related to the variation of salinity.Abstract in English:

Use of nest-boxes for management of cavity nesting birds in anthropic areas can give good results. In November 1987, data collection begun in UNICAMP, Campinas (São Paulo), with the objective of favouring establishment and increase in urban bird communities. The House Wren (Troglodytes aedon Viellot. 1807) and House Sparrow (Passer domesticus Linnaeus, 1758) used the nest boxes for reproduction. Nests were collected and analysed (weight, used materials, incubation chamber materials, nest form). House Sparrow used thin materials, like straw, paper and plastic, while house wren used heavy materials, like sticks, wire and tabs of soff drink cans. The nest-boxes offered favorable conditions to bird reproduction and protection in disturbed areas, and showed signs of leading to increase in diversity of species, that might use this nest-boxes for reproduction in the future.Abstract in English:

In order to analyse the diet of Schizodon intermedius Garavello & Britski, 1990, captures were made every season during the period of April/1990 to February/1991, using gillnets of different mesh size at Sertanópolis, a region of Paraná State. An analysis of stomach fullness degree was made upon 76 individuals (including young ones). A sample of 20 adult specimens was chose to compare the morphology of the digestive tract with the diet found. It was concluded that S. intermedius is a grazer herbivore whose principal diet consists of leaves and stalks of two monocotyledonous plants: Poaceae and/or Cyperaceae. This species shows quanlitative, but not qualitative feeding seasonal variations. It was verified that intestinal quotient of the species is X = 1.34, the variation of gill rakers number is 18-23 and of the pyloric caeca number is 15-25. These morphological characteristics found in this species are typical of herbivore fishes.Abstract in English:
This study gives information on the feeding habits of 1,015 specimens, belonging to the five most abundant fish species in the Jacarepagua Lagoon, captured between March 1990 and February 1991, using trawl net. A feeding index was introduced to compare the relative importance of various food items, according to species standard length. A clustering analysis was calculated by using numerical coefficient of food items and defined two main groups: The 1 st represented by Xenomelaniris brasiliensis (Quoy & Gaimard, 1824) and Jenynsia lineata (Jenyns, 1842) considered omnivorous, fed mainly on insects, and the second including Tilapia rendalli (Boulenger, 1896), Phalloptychus januarius (Hensel, 1868) and Poecilia vivipara (Bloch & Schneider, 1801), whose principal diet source was epibenthic cyanophytes, specially Microcystis sp. and Lyngbia sp.
