1) Using several methods, the larval food of Melipona quadrifasciata was found to contain amounts of acetylcholine estimated to range between O. 5 and 2.0 mg. equivalents of acetylcholine chloride per gram of larval food. Similar amounts have been reported for the larval food of the honey, bee, Apis mellifera. 2) The larval food of M. quadrifasciata was also found to contain a large amount of choline and an unidentified substance that was soluble in ethanol, gave a blue fluorescence, reacted with Dragendorf's reagent, and had a weak acetylcholine-like action. In one sample of larval food, a substance with the properties of glycine betaine was also found. 3) Samples of stored pollen were also found to contain acetylcholine, choline and the unidentified... |

1. The blood of the larval honey bee at different stages of development has been subjected to the chemical analyses customary for routine examination of human blood. Certain of both the organic and inorganic constituents vary widely from the mammalian values. 2. Of the organic constituents, sugars are above normal for the mammal during the feeding period, but during pupation reach a level comparable to the mammalian level. Amino acids are 50 times higher, proteins slightly lower, fats higher than in the mammal. 3. Of the inorganics, the sodium and chlorine are very low, potassium, phosphorus, calcium, and magnesium high, and total salt content much lower than in mammalian plasma. 4. Osmotically the amino acids are the most effective fraction, having almost... |

The aim of this paper is to evaluate to what extent, the study of feeding regimes of fish could be valuable to indicate the possibilities and the constraints of their domestication. Though the natural feeding regime of fish seems to be disadvantageous for their domestication, as protein requirement is high, different species could be considered as domesticated. These species are herbivorous, detritivorous, omnivorous as well as carnivorous. In the same way, there are large differences in gut anatomy, but domestication concerns species with or without stomach, and species with short or very long intestine. Nutritional requirements do not allow predicting species that could be domesticated. Some species seem to be able to use vegetable protein in... |

1- The presence of labile P compound in the excreta of Galleria mellonella was proved. This compound is present in great quantities and constitutes about 60-90% of the total P excreted. 2- It is likely that this compound is a metaphosphate because : a- it is acid and water soluble, b- it is converted into orthophosphate after 7 minutes hydrolysis with N hydrochloric acid at 100°, c- it is a barium insoluble compound, d- it is precipitated by lead salts at pH=2, e- it precipitates proteins, f- it gives the positive metachromatic reaction with toluidine blue. 3- This compound is found in excreta of both feeding and starving larvae as well as in the meconium of moth. 4- The presence of enzyme in the body of larvae, transforming the metaphosphate into... |
