| Abstract: Antifeedant and repellent effects of two different extracts from native Solanum species Solanum bistellatum and Solanum sisymbrifolium on Cryptotermes brevis were evaluated. The extracts obtained, particularly the dichloromethane extracts and the enriched fraction of sugar esters from S. sisymbrifolium and S. bistellaltum, showed antifeedant and repellent action against the termite. The antifeedant effect of dichloromethane extract from S. sisymbrifolium at the concentration of 25.00mg/mL reached 100%, while the repellent action of the dichloromethane extracts and that of the enriched fraction of sugar esters at the concentration of 1.00mg/mL was higher than 90%. In case of S. bistellatum, the antifeedant effect of the dichloromethane extract and... |

| 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... |

| 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 greater... |

| 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... |

| 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... |

| 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... |

| Avaliou-se o comportamento de borregos Morada Nova confinados e alimentados com fontes alternativas de proteína na ração concentrada. Utilizaram-se três diferentes fontes protéicas alternativas na ração concentrada em substituição ao farelo de soja: feno do folíolo da leucena (FFL), uréia (ambas substituindo 100% do farelo de soja) e torta de algodão (substituindo em 51,8%, com base na matéria seca). Ao longo de 24 horas e a intervalos de 10 minutos foram estimados o tempo de ingestão de ração, de ruminação, de outras atividades e de ócio, acordado ou dormindo. Nos intervalos entre as observações acima, foi acompanhada a freqüência de defecação, micção e ingestão de água. Não houve diferença entre tratamentos para o tempo de ingestão de ração e de ócio... |

| 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... |
