The objective of this research was, based on biological studies, to determine and adequate diet for rearing Corcyra cephalonica (Stainton, 1865) in the laboratory so as to permit the rearing of this factitious host for Trichogramma mass production. The research was conducted at 25 ± 1ºC, RH 60 ± 10% and photophase of 14 hours. Six artificial diets were compared: a) whole wheat flour (48.5%), ground rice (48.5%) and sugar (3%); b) ground rice (97%) and sugar (3%); c) whole wheat flour (48.5%), rice flour (48.5%) an sugar (3%); d) whole wheat flour (97%) and yeast (3%); e) wheat germ (97%) and yeast (3%); f) rice bran (94%), sugar (3%) and yeast (3%); f) rice bran (94%), sugar (3%) and yeast (3%). All of the diets studied permitted the development of C.... |

ABSTRACT Although dry bulb temperature (T) is the environmental variable most commonly used to classify thermal comfort in pigs, environmental assessment ratios provide more accurate information. The objective of this study was to correlate the sound pressure levels (SPL) produced by piglet vocalization with the thermal environment observed during the nursery phase, and subsequently establish thermoneutrality ranges. The experiment was conducted on a pig farm where T, relative humidity (RH), and SPL data were recorded between 9 am-5 pm for 42 days. The association between SPL and T in nursery phase piglets was verified; for thermal comfort to be possible, SPLs were 56.3 to 60.3 dB. The SPLs were subsequently used in predictor equations of ratios, and... |

Pesquisas comprovam que o uso de leguminosas em consórcio com gramíneas pode reduzir os gastos diretos com fertilizantes e suplementos proteinados, aumentar a qualidade da dieta consumida pelos animais, melhorar a disponibilidade de forragem e ampliar o período de utilização das pastagens. Nesta publicação serão apresentados os resultados de experimentos conduzidos em fazenda comercial, no estado do Acre, mostrando a superioridade do desempenho produtivo de bovinos da raça Nelore e cruzados meios-sangues Nelore e Aberdeen Angus, na fase de recria, em pastos de capim-humidícola consorciados com amendoim forrageiro 'BRS Mandobi'. Esta publicação está de acordo com os Objetivos de Desenvolvimento Sustentável 2 (Fome Zero e Agricultura Sustentável), 12... |

The indigenous oyster of mainland France, the fiat oyster, Ostrea edulis has been part of the human diet for centuries. The Romans collected them and exported them to Rome. Although tanks for holding oysters after harvesting were in use at that time (GreIon 1978) it seems that true culture was not developed along the coast contrary to the records of Pliny the Older. It appears that oysters were already being captured on hoards off the Italian coast. The exploitation of natural stocks continued through the Middle Ages and the Renaissance. However, it was not until the 17th century that oyster culture began, first in the pools of the salt marshes of the Atlantic coast and then in specially managed ponds. Papy (1941) repeats a good description given in 1688... |

The whole of experiments carried on from thermal constraints on the larval development of Palaemon serratus allows the following observations: -individual rearings obtain the best survival rates in the witness groups and neutralize by a dense food and the absence of intraspecific cannibalism, factors which can interfere with the results ascribed only to the experiments; - slight thermal increases (10 and 12 degree C) do not involve secondary effects on the post larvae when the development is realized at 20 degree C; - if the TL 50 is reaching 34 degree C, letal effects are observed, as soon as the final temperature; - whatever is the temperature increase, the relation = mortality/temperature reached is similar and this factor mortalities observed, that... |

The digestive tract of crustacea is complex. It is composed of a shor t oesophagum, a stomach with two bags, and internal wall with appendags specialized in grinding of feeds. These hard mastication pieces represent the gastric mill. Setae, filters included in the stomach structure allow the separation between food particles and liquid compounds. Those one are coming over through filters and more on to the digestive gland tubules or mid gut gland. In this organ, several types of cells play specialized functions: absorption, enzyme secretion, stocking function. Some cells of a new type, with undefined function, may be neurosecretions function, have been described recently. The end of tubules of digestive gland exhibits cells with embryonic characteristics.... |

A disease whose severity seems directly bound to conditions of cultivation can cause a heavy mortality in the common prawn Palaemon serratus (Pennant) at molting. The causative agent, A. rodor, is a ciliate, a common external parasite whose life cycle is adapted to the molting cycle of the shrimp. The principal factors favorable to the development of the parasite were studied: age of the host, water temp, numbers of shrimps as a function of the quantity of water and its renewal. The sp A. rodor, although related to the Conidophryidae, Kirby, 1941 (1936) has significant differences (1) in its ethology (it feeds on the exoskeleton without penetrating to its hosts' tissues), (2) in its vegetative multiplication (tomitogenesis combines the cortical... |
