Índices climáticos e infestação predial por larvas de Aedes aegypti (Linnaeus, 1762) e Aedes albopictus (Skuse, 1894) em Araçatuba-sp Brasil

Aedes is synanthropic; associated with climatic conditions and urban environment. This study performed a retrospective evaluation of the climatic indices and the A. aeypti and A. albopictus infestation larvae rates (IP), registered from the month of October, 2005 to 2009, in the Araçatuba city, São Paulo State. There was no variation in the average temperature in the period (26.3°C). The rain falls were high in 2005 (133.5 mm3 ) fell in 2006, 2007 and 2008 (55.0 mm3 , 78.5 mm3 and 79.0 mm3 , respectively) and increased in 2009 (104.0 mm3 ). The infestation IP was 1.10, 1.39, 0.36, 0.28 and 3.30, respectively in 2005, 2006, 2007, 2008 and 2009, none of them were A. albopictus larvae. There was no association between IP and temperature, but there was significant difference (P <0.001) between the IP of 2009, with the IP of 2007 and 2008. This study it was concluded that among the environmental factors just rain influenced the rate of larvae, "infestation", committed only by A. aegypti.

Susceptibilidade antimicrobiana de amostras de escherichia coli isoladas de frango industrial (gallus gallus domesticus - linnaeus, 1758) com colibacilose

The present study evaluated the susceptibility of Escherichia coli samples isolated from poultry with colisepticemia in midwestern São Paulo State at the Ornitopathology Laboratory of FMVZ-UNESP/Botucatu, SP. A large number of samples were found that were multi-resistant to the antibiotics tested, the less effective drugs being sulfonamide and tetracycline. All samples were susceptible to norfloxacin and gentamicin.

Valores de referência de uréia e creatinina para javali (sus scrofa scrofa, linnaeus, 1758) em cativeiro

In Brazil, the commercial breeding of wild boars (Sus scrofa scrofa) is rapidly expanding. Given the significance of reference values for biochemical analysis for diagnosis of pathological processes and the limitation of data in the literature on this species, Blood samples were collected for determination of biochemical values in 160 wild boars from 180 to 300 days old, clinically healthy farms. The reference range for creatinine was similar to the normal range for swine (1,0 – 2,7mg/dL). There were differences between genders, only for the determination of urea, where the males were higher, although similar to pigs (10 – 30mg/dL). The females, with values from 13.03 to 44.78 mg / dL, do not have statistically significant.

Ecologia alimentar de Tatu-Peba, Euphractus sexcinctus (Linnaeus, 1758), na Fazenda Nhumirim, Pantanal da Nhecolância, MS

Studies on feeding ecology are important tools for the understanding of feeding strategies and niche dynamics. Information on the type of food consumed, how, and where it is acquired, enable the elucidation of species behavioral, evolutionary and ecological aspects. The diet study based on fecal material enables a low-cost, informative research and avoids the sacrifice of animals. The general aim of this study is to characterize the diet of Euphractus sexcinctus, the yellow-armadillo, based on fecal samples, to contribute with additional information on their feeding habits. The study was undertaken at the Nhumirim ranch, Pantanal da Nhecolândia, MS, during the months of February and March, 2014. The fecal material was collected during the manual capture of the animals and oven dried at 60°C. The food items found in the feces were sorted using a magnifying glass and separated in the following categories: plant matter, invertebrates and soil. Invertebrates were identified to the order level and the plant matter to the lowest taxonomic level possible. Aiming to evaluate the invertebrate availability in the soil, pitfall traps were installed next to the location where individuals were captured, during the months of April and May. We were able to estimate the frequency with which item was consumed during the studied period, and if there is a relationship between the frequency of consumed invertebrates and their availability environment. Among the analyzed samples, we could observe the frequency of occurrence (FO) of plant matter, invertebrates and soil in all the samples. The main invertebrate orders found in the samples were: Coleoptera, Orthoptera and Hymenoptera, with FO of 100%, 100% and 87,5%, respectively. Seeds were found in 100% of the samples. The FO of the Byrsonima orbignyana was high (62,5%), and evidences the potential of the yellow-armadillos as seed dispersers. The use of other techniques, such as the micro-histological...

Growth of the mangrove crab Ucides cordatus (Brachyura, Ocypodidae)

During monthly samplings between September 1998 and August 2000. 3,660 specimens of Ucides cordatus (Linnaeus, 1763) (2054 males and 1606 females) were obtained and examined for size (CW carapace width) to determine growth-age equations for each sex. This species showed a slower growth, with a marked seasonal oscillation, in females as compared to males, suggesting application of the seasonal and nonseasonal von Bertalanffy growth model, respectively. CW&PROP; and k constant were closely similar for the two sexes (CW&PROP; (male) = 90.3 mm: CW&PROP; (female) = 88.6 mm; k(male) = 0.28; k(female) = 0.26). The age at sexual maturity was estimated to be around 3 years, while the age at legal size (CW = 60 mm) was 3.8 and 4.7 years for males and females, respectively. In the laboratory, juvenile stages did not show differences in growth rates under the same temperature and photoperiod conditions.

DIET of THE BLUE MARLIN (MAKAIRA NIGRICANS, LACEPEDE 1802) (PERCIFORMES: ISTIOPHORIDAE) of THE SOUTHWESTERN EQUATORIAL ATLANTIC OCEAN.

Diet composition of the blue marlin, Makaira nigricans, from the southwestern equatorial Atlantic Ocean was analyzed between October 2004 and November 2005. In the 226 stomachs of fish ranging between 100 and 311 cm lower jaw -fork length (LJFL), 44 items were identified, including 31 fishes and 13 cephalopods. Seventy stomachs were empty (23.6 %). M. nigricans fed preferentially on heavy and muscular scombrid fishes especially upon the skipjack tuna, Katsuwonus pelamis (Linnaeus, 1758), probably to sustain their high metabolism, and on a variety of other items composed mainly by epipelagic species of fish and cephalopods.

The effect of increased light intensity on the aggressive behavior of the Nile tilapia, Oreochromis niloticus (Teleostei: Cichlidae)

Animals show behavioral and physiological changes that emerge in response to environmental perturbations (i.e., emergency life-history stages). In this study, we investigate the effects of light intensity on aggressive encounters and social stability in groups of adult male Nile tilapia, Oreochromis niloticus (Linnaeus, 1758). The study compared the behavior observed under low (280.75 ± 50.60 lx) and high (1394.14 ± 520.32 lx) light intensities, with 12 replicates for each treatment. Adult fish were isolated in 36-L aquaria for 96 hours, and three males were grouped for 11 days in 140-L aquaria. Agonistic behavior was video-recorded (10 min/day) on the 3rd, 5th, 7th, and 9th day to quantify aggressive interactions and social stability. There was an effect of light intensity and day of observation on the total number of agonistic behaviors performed by the fish group. Besides, increased frequency of aggressive interactions (the sum of the four sessions) by the alpha, beta and gamma fish occurred at the higher light intensity. The dominance ranks of the fish remained unchanged across the observation sessions under both the low and high light intensities. We concluded that enhanced light intensity has a cumulative effect that increases the aggressiveness of the Nile tilapia but that this effect is not sufficiently strong to destabilize the social hierarchy.

Visitantes florais de Lagerstroemia speciosa Pers: (Lythraceae)

Studies were carried out with Lagerstroemia speciosa Pers. on floral reproductive systems, diversity and constancy of visiting insects at different hours of day, the behaviour of these insects at the flowers and the influence of these environmental factors in relation to their visits. The fenology, anthesis and others particularity of this vegetal species was studied. A great diversity of insects was verified visiting the flowers with the predominance of bees. The most frequent and constant species encountered were: Nannotrigona testaceicornis (Lepeletier, 1836) (40,2%), Tetragonisca angustula (Latreille, 1811) (16,9%), Apis mellifera Linnaeus, 1758 (11,8%), Plebeia droryana (Friese, 1900) (9,1 %) e Exomalopsis fulvofasciata (Smith, 1879) (8,5%). The blossoms possessis features of melittophily syndrome and diurnal anthesis. The environmental factors influence the insects foraging activity, mainly temperature, light, time of day, humidity and wind speed. The effective pollinators were the large insects like Bombus morio (Swederus, 1787), Bombus atratus (Franklin, 1913), Centris tarsata (Smith, 1874), Centris flavifrons Fabricius, 1775, Xylocopa suspecta Camargo & Moure, 1988, Xylocopa frontalis (Olivier, 1789) and Eulaema nigrita Lepeletier, 1841.
