A new approach to feed frequency studies and protein intake regulation in juvenile pirarucu Anais da ABC (AABC)
MATTOS,BRUNO O. DE; NASCIMENTO FILHO,EDUARDO C.T.; SANTOS,ALINE A.; BARRETO,KAYCK A.; SÁNCHEZ-VÁZQUEZ,FRANCISCO J.; FORTES-SILVA,RODRIGO.
ABSTRACT This study aimed to investigate pirarucu's (Arapaima gigas) ability to trigger a self-feeding system to regulate protein intake between two standard diets that contained 39% and 49% of crude protein. The same system allowed the evaluation of daily feeding and locomotor activity rhythms. Eighteen fish (654.44±26.85g) were distributed into six 250 L tanks (3 fish/tank). Fish had free access to both diets (39% vs. 49% protein) by feeders (2 per tank), adapted to be activated by fish themselves. This system was connected to a computer system. After an adaptation period, fish learned to activate feeders and the mean food intake recorded was 2.14% of their body weight on a daily basis. Fish showed feeding (72.48%) and locomotor (72.49%) activity...

Alimentary canal and reproductive tract of Hypothenemus hampei (Ferrari) (Coleoptera: Curculionidae, Scolytinae) Neotropical Entomology
Rubio G.,José D.; Bustillo P.,Alex E.; Vallejo E.,Luis F.; Acuña Z.,José R.; Benavides M.,Pablo.
The alimentary canal and the reproductive tract of males and females of Hypothenemus hampei Ferrari are described. The alimentary canal of H. hampei showed the crop with several spine-like structures and the midgut with few gastric caeca. We evidenced for the first time that adult females need to feed on coffee in order to produce viable eggs before and during oviposition period. The presence of air bubbles inside the anterior midgut may be due to starvation rather than the response of the environment during flying as previously reported. Two ovaries and the same structures and arrangements common to individuals of the Curculionidae beetles composed the female reproductive system. The male reproductive tract showed a significant difference with respect to...

Associative learning in wild Anastrepha obliqua females (Diptera, Tephritidae) related to a protein source Iheringia, Sér. Zool.
Cresoni-Pereira,Carla; Zucoloto,Fernando S..
The aim of the present study was to determine whether wild adult Anastrepha obliqua (Macquart, 1835) females are able to associate a compound (quinine sulphate - QS) not related to their habitual diet with a protein-enriched food. Females were first fed on diets based on brewer yeast and sucrose containing or not QS. The groups were then allowed to choose between their original diets and a diet with or without QS, depending on the previous treatment, and between a diet based on agar and a diet containing agar and QS. When the nutritional value of the diets was adequate, the females did not show any preference for the diet with or without QS. With respect to the agar diet and the agar + QS diet, females previously fed on a nutritive diet containing QS...

Bat necrophagy by a whip-spider (Arachnida, Amblypygi, Phrynidae) in a cave in the eastern Brazilian Amazon Acta Amazonica
PROUS,Xavier; PIETROBON,Thadeu; RIBEIRO,Mariane S.; ZAMPAULO,Robson de A..
ABSTRACT Amblypygids are among the main predators in the ferriferous caves in Carajás National Forest, state of Pará (Amazon region of Brazil). One of the most common amblypygid species in this region is Heterophrynus longicornis (Butler 1873), and its most frequent prey are crickets of the family Phalangopsidae, which are abundant in the caves of Pará. Because they are primarily predators, necrophagy by amblypygids is not frequent in nature, and there are only two literature records of necrophagy of bats by Amblypygi. On December 11th, 2013, we observed an individual H. longicornis eating a bat carcass in a Pará ferriferous cave. The amblypygid exhibited considerable interest in the bat’s carcass, and it did not interrupt its meal even when lamps or a...

Biology and nutrition of Spodoptera frugiperda (Lepidoptera: Noctuidae) fed on different food sources Scientia Agricola
Silva,Débora Mello da; Bueno,Adeney de Freitas; Andrade,Karine; Stecca,Cristiane dos Santos; Neves,Pedro Manuel Oliveira Janeiro; Oliveira,Maria Cristina Neves de.
ABSTRACT: We studied Spodoptera frugiperda development using different food sources in the laboratory and field. Newly hatched larvae were fed soybean, cotton, maize, wheat, and oat leaves. An artificial diet was used as the control. Duration of pre-pupal, pupal, and larva-adult period, pupal weight, sex ratio, survival, larva feeding preferences, oviposition preferences, and nutritional quality of different hosts were evaluated. Insects fed on wheat showed the shortest larva-adult period. The insects fed on cotton and soybean had longer larval development cycles and pupae of lower weight. Feeding preference was evident for third instar larvae and did not differ between wheat, oat, maize, and soybean, which were the preferred hosts. Moths oviposited to a...

Body position of the stink bug Dichelops melacanthus (Dallas) during feeding from stems of maize seedlings. Repositório Alice
PANIZZI, A. R.; LUCINI, T..
The Neotropical green-belly stink bug, Dichelops melacanthus (Dallas) is a major pest of maize, Zea mays L. in the main production areas of Brazil. It usually feeds on the stems of young plants (seedlings) causing heavy damage by affecting the plant growth and mitigating seed yield. Laboratory studies were conducted to determine body position (upward or downward) of the bug on plant (seedling) stem during feeding and not feeding activities. Ten visual records were taken per day, each spaced one hour during 30 days of 10 adult bugs of similar age exposed to maize seedlings inside cages (plastic tubes). At each observation, it was recorded if the bug was feeding on the stem (i.e., stylets inserted into the plant tissue) or not, and its body position. During...

Brief daily postpartum separations from the litter alter dam response to psychostimulants and to stress BJMBR
Silveira,P.P.; Benetti,C. da Silva; Portella,A.K.; Diehl,L.A.; Molle,R. Dalle; Lucion,A.B.; Dalmaz,C..
Neonatal handling induces several behavioral and neurochemical alterations in pups, including decreased responses to stress and reduced fear in new environments. However, there are few reports in the literature concerning the behavioral effects of this neonatal intervention on the dams during the postpartum period. Therefore, the aim of the current study was to determine if brief postpartum separation from pups has a persistent impact on the dam's stress response and behavior. Litters were divided into two neonatal groups: 1) non-handled and 2) handled [10 min/day, from postnatal day (PND) 1 to 10]. Weaning occurred at PND 21 when behavioral tasks started to be applied to the dams, including sweet food ingestion (PND 21), forced swimming test (PND 28), and...

Cardiovascular responses to locomotor activity and feeding in unrestrained three-toed sloths, Bradypus variegatus BJMBR
Duarte,D.P.F.; Jaguaribe,A.M.; Pedrosa,M.A.C.; Clementino,A.C.C.R.; Barbosa,A.A.; Silva,A.F.V.; Gilmore,D.P.; Da Costa,C.P..
Heart rate (HR) and systolic (SBP), diastolic (DBP) and mean (MBP) blood pressure were recorded by biotelemetry in nine conscious unrestrained sloths for 1 min every 15 min over a 24-h period. The animals were allowed to freely move in an acoustically isolated and temperature-controlled (24 ± 1ºC) experimental room with light-dark cycle (12/12 h). Behavior was closely monitored through a unidirectional visor and classified as resting (sitting or suspended), feeding (chewing and swallowing embauba leaves, Cecropia adenops), or locomotor activity around the tree trunk or on the room floor. Locomotor activity caused statistically significant increases in SBP (+8%, from 121 ± 22 to 131 ± 18 mmHg), DBP (+7%, from 86 ± 17 to 92 ± 10 mmHg), MBP (+8%, from 97 ± 19...

Barros,Helenice P; Valenti,Wagner C.
Feeding behavior of the larvae's prawn, Macrobrachium rosenbergii De Man, 1879, in each stage of development was studied face alArtemia Linnaeus, 1758 nauplii, dry and wet diets. Groups of ten larvae in each stage were placed in 500 ml beakers at 29ºC in filtered brackish water. After the fasting period of acclimatization, the three types of food were offered separately to the larvae and the feeding behavior was observed during 30 min. Feeding perception, capture, grasp and ingestion of food were used to determine feeding pattern. Stage I lawac do not eat. The feeding behavior of larvae was similar on the stages II - XI. The perception in distance does not occur in most individuais; the feeding process generally started with the physrcal contact of food...

Comportamento alimentar e dieta da "falsa-coral" Oxyrhopus guibei Hoge & Romano (Serpentes, Colubridae) Zoologia
Andrade,Rogério de Oliveira; Silvano,Renato A. Matias.
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.

Comportamento alimentar e dieta de Phrynops hilarii (Duméril & Bibron) em cativeiro (Reptilia, Testudines, Chelidae) Zoologia
Molina,Flavio de Barros; Rocha,Mario Borges da; Lula,Luiz Antônio Beserra de Mello.
Since 1985 the biology and behavior of Phrynops hilarii (Duméril & Bibron, 1835) at São Paulo Zoo is being studied. Feeding behavior is divided in five phases (foraging, approach, capture, dilaceration and ingestion), but not necessarily all of them happen. During phase 1 the food or prey seems to be visually located. During phase 2 the food itens and stationaty preys are approached and examined by olfaction. Moving preys are pursued and there is no olfactory examination. During phase 3 the food is captured by suction. When food is bigger than turtle mouth it is dilacerated by one or both forefeet used alternately (phase 4). Ingestion is accomplished by gradual suction (phase 5). Intra and inter-specific cleptoparasitism was observed. Success in...

Diet and ecomorphology of predator fish species of the Amazonian floodplain lakes Biota Neotropica
Cardoso,Diogo Campos; deHart,Pieter; Freitas,Carlos Edwar de Carvalho; Siqueira-Souza,Flávia Kelly.
Abstract: Amazonian floodplain lakes host a high diversity of predatory fish which coexist and exploit the high diversity of available prey. Morphology could be the characteristic most closely associated with their preferred feeding sources (prey). However, it is unclear whether this association is direct or indirect. If it is indirect, swimming performance or preferential position in the water column could be the most evident characteristic. To examine the degree to which fish morphology of predator fish species is correlated to their dietary inputs, we compared the existence of morphological and feeding dissimilarity among eight predator species with the association between predator morphologies and preferred prey. We collected, measured, and sampled the...

Dieta de um grupo de mico-leão-preto, Leontopithecus chrysopygus (Mikan) (Mammalia, Callitrichidae), na Estação Ecológica dos Caetetus, São Paulo Zoologia
Passos,Fernando de Camargo.
In this study carried out in the Caetetus Ecological Station, Sao Paulo, southeastern Brazil, a wild group of black lion tamarins was accompanied during 1989 to 1991, to analyse the dietary habits of the species. The scan sampling method was used to gather data. A total of 961 behaviors were recorded, of which feeding occupied 23.3% of the time involved in the behaviors. The major dietary components observed in the black lion tamarins were fruits, tree exudates and animal preys (67.9%, 22.8% and 8.9% respectively). Fruits varied monthly from 47.4 to 97.1 %, being consumed more during the rainy season, while tree exudates varied from 0 to 54.7%, and were consumed mainly during the dry season. The animal prey accounted for 0 to 15.8% of the diet. The most...

Dietary protein and carbohydrate affect feeding behavior and metabolic regulation in hummingbirds (Melanotrochilus fuscus) RChHN
ZANOTTO,FLAVIA P.; BICUDO,J.E.P.W..
The objective of this work was to link hummingbird feeding behavior with metabolic regulation and in addition to assess whether dietary composition would affect entrance into torpor. Hummingbirds were fed a combination of diets with contrasting amounts of protein and carbohydrate. The diets were composed of the following: 2.4 % protein (P) - 12 % sucrose (S) and 0.8 % protein (P) - 36 % sucrose (S). The main findings showed that periods of feeding on each of the diets could be distinguished as separate bouts or feeding events. Hummingbirds presented to high protein-low carbohydrate diets (2.4P-12S) ingested a larger volume of diet, fed for longer (both around 1.7x) and increased the interval between feedings compared with hummingbirds fed diets 0.8P-36S....

Effects of betaine on the growth of the fish piauçu, Leporinus macrocephalus BABT
Normandes,Edivaldo Bento; Barreto,Rodrigo Egydio; Carvalho,Robson Francisco; Delicio,Helton Carlos.
In this study was tested the effect of betaine on the growth performance of the piauçu fish. For this, twenty-one fish (mean ± SD: body weight: 14.9 ± 1.3 g) were randomly distributed in one out of three experimental treatments (n = 7 each; 1 fish/aquarium): without betaine added in the food (control); 3.6 g betaine/Kg of food; 7.1 g betaine/Kg of food. The fish were exposed to experimental conditions for 60 days. Fish presented significant growth throughout experimentation, but no statistically significant difference was found for any parameter analyzed among the treatments, except for condition factor, which was higher in control group than betaine ones. Accordingly, it was concluded that betaine had no enhancing effect on growth of piauçu.

ABSTRACT The host acceptance behavior and environmental factors as temperature affect the feeding behavior of Lepidoptera pests. Thus, they must be considered in studies about the risk potential of resistance evolution. The current study sets the differences in the feeding behavior of neonate Alabama argillacea (Hübner) (Lepidoptera: Noctuidae) larvae exposed to Bt and non-Bt cotton plants, under different temperatures and time gap after hatching. Two cotton cultivars were used: the Bt (DP 404 BG - bollgard) and the non-transformed isoline, DP 4049. We found that the feeding behavior of neonate A. argillacea is significantly different between Bt and non-Bt cotton. Based on the number of larvae with vegetal tissue in their gut found on the plant and in the...
