Acetylcholine in the larval food, honey, and stored pollen of a stingless bee, Melipona quadrifasciata National Institute of Agronomic Research
Welsh, John H.; Nogueira-Neto, Paulo; Jaeger, Celso P.; Ancona Lopez, Ana Amelia.
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...

Ætiology of european foul brood ; a disease of the larval honey-bee National Institute of Agronomic Research
Bailey, L..
THE cause of European foul brood was originally thought to be Bacillus alvei or a mixture of B. alvei and Streptococcus apis. The causative organism was later named and described by White as Bacillus pluton, a lanceolate Gram-positive bacterium. This organism is the first of several which have been found to appear in diseased larvæ. However, White and others failed to culture B. pluton in vitro and it was afterwards considered to be a dissociant form of Bacillus alvei, of Bacterium eurydice, or of both. Others have maintained that B. pluton is a separate organism. It has been pointed out that Streptococcus pluton would be a more suitable designation than Bacillus pluton both on morphological grounds and in the absence of evidence that it forms spores. For...

Bacillus larvae : its cultivation in vitro and its growth in vivo National Institute of Agronomic Research
Bailey, L.; Lee, D.C..
Spores of Bacillus larvae White germinate and make initial vegetative growth best in a limited range of low redox potentials, but later growth and sporulation occur best aerobically. Different media needed for best results with each phase of development of the bacillus are described. Spores of B. larvae germinate in the mid-gut contents of honey-bee larvae up to 2 days old. The vegetative forms then migrate and become closely applied to, but do not penetrate, the mid-gut epithelium. Most organisms seem to be voided with the contents of the intestine when an infected larva defaecates shortly before it pupates. A few organisms are presumably left in the intestine and probably invade the tissues of the larva as it pupates.

Body fluid of the honey bee larva - I. Osmotic pressure, specific gravity, pH, O2 capacity, CO2 capacity, and buffer value, and their changes with larval activity and metamorphosis National Institute of Agronomic Research
Bishop, George H..
1. Specific gravity of mature larvae of worker honey bees is 1.045. 2. The osmotic pressure of worker larval blood in terms of freezing point lowering gives a value of -0.86°C., and the osmotic pressure decreases during pupation. 3. The pH of larval blood (measured at 25°) is near 6.8, varying with conditions in the hive. 4. The oxygen capacity of larval blood is within a reasonable error the amount that could be physically dissolved, and no evidence of a chemical carrier is found. The content decreases during spinning, when the larva is enclosed in a cocoon, because diffusion is cut down while consumption increases. 5. CO2 absorption curves indicate that the blood (of drone larvae) decreases in CO2 capacity and content during spinning of the cocoon, but...

Body fluid of the honey bee larva - II. Chemical constituents of the blood, and their osmotics effects National Institute of Agronomic Research
Bishop, George H..
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...

Domestication and nutrition in fish ArchiMer
Cahu, Chantal.
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...

European foul brood : a disease of the larval honeybee (Apis mellifera L.) caused by a combination of streptococcus pluton (Bacillus pluton White) and Bacterium eurydice White National Institute of Agronomic Research
Bailey, L..
Result of preliminary experiments have shown that European foul brood disease of the larval honeybee can be caused in bee colonies by spraying their brood with suspensions of Streptococcus pluton (Bacillus pluton White) and Bacterium eurydice White if the two organisms are grown together in mixed anaerobic culture ; fifth subcultures of a mixed culture were usually virulent, although virulence diminished rapidly after further sub-cultivation. It was not possible to cause the disease by simultaneous inoculation with separate cultures of the two organisms. As there is a tendency for colonies of S. pluton and B. eurydice to grow within, or upon, each other on agar in anaerobic cultures, the separate cultures of each organism were subcultured five times to try...

Growth rates of honey bee larva National Institute of Agronomic Research
Bishop, G.H..
The curve of growth of the queen bee larva is exponential during 4 days from hatching of the egg, the weight increasing by a factor of 5 each 24 hours. The weight of the worker larva deviates from this curve and after two days increases at a decreasing rate. The worker matures later than does the queen larva. Volumes both of the cells of the fat body and of their nuclei increase at a decreasing rate. The cytoplasm increases much more rapidly than does the nucleus, from about one-half the cell volume at hatching to nine-tenths at larval maturity. The nuclear changes initiated at beginning of metamorphosis precede the cessation of feeding, and in the queen larva nearly coincide with the sealing over of the wax ceIl, after which the larva continues to feed...

Respiration rates of larvae of drone and worker honey bees, Apis mellifera L. National Institute of Agronomic Research
Allen, M. Delia.
The oxygen consumptions of drone and worker honey bee larvae were determined at 32. over the period between hatching 1Ind the sealing of the cells prior to pupation. A decrease in respiration rates with increasing age was found in both drone and worker larvae when the rates were calculated 011 a unit weight basis, but in both castes the oxygen consumption per larva rose rapidly in the period following hatching, subsequently increasing less rapidly. Drone larvae consumed greater amounts of oxygen than worker larvae of the same weight, and this was apparently linked with their more rapid increase in weight.

Studies in the biochemistry of waxmoth (Galleria mellonella) - 6. Metaphosphate in the excreta of Galleria mellonella National Institute of Agronomic Research
Niemierko, Stella; Niemierko, W..
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...

Studies in the mode of action of royal jelly in honeybee development : III. The effect of experimental variation in diet on growth and metabolism of honeybee larvae National Institute of Agronomic Research
Dixon, S.E.; Shuel, R.W..
Norms were established for respiration, growth, and tissue composition of 0- to 72-hour-old female honeybee larvae reared in the laboratory on natural royal jelly and worker jelly diets. The worker jelly diet was then altered experimentally in the direction of royal jelly through additions of sugar and certain water-soluble acids of unknown structure extracted from royal jelly, but present in the natural diets of larvae of both female castes. In general, developmental norms were shifted in the direction of the norms of larvae fed royal jelly, but the changes were not fully co-ordinated. The added acids were strongly growth inhibitory. A high inverse association between the total water-soluble acid content of the diet and larval weight suggested that the...

Studies in the mode of action of royal jelly in honeybee development : IV. Development within the brain and retrocerebral complex of female honeybee larvae National Institute of Agronomic Research
Canetti, Sylvia J.; Shuel, R.W.; Dixon, S.E..
Histological evidence is presented for a caste difference in endocrine activity during the critical period of determination in the larval honeybee. Until the Last larval instar, neurosecretory cells in the brain of the honeybee larva remain undifferentiated. During this undifferentiated period there is a quantitative difference in apparent activity, as evidenced by the frequency of occurrence of cytoplasmic particles in certain large neuroblasts. Whereas the histological criteria for neurosecretory cells cannot be fulfilled, the brain is presumably exercising a regulatory role in growth and development. These large neuroblasts with phloxinophil inclusions are the likely candidate cells. Between the ages of 40 and 80 hours there is considerably more...

The epidemiology and control of nosema disease of the honey-bee National Institute of Agronomic Research
Bailey, L..
The proportion of honey-bees infected with Nosema apis (Zander) declines in summer as the old infected bees die, for they cease to transmit their infection to the newly emerged individuals during the flying season. N. apis spores survive the summer on combs contaminated with infected faeces during the preceding winter. Although bees clean the combs during the summer, all infected material is not removed, and even well-used brood comb, which has been repeatedly cleaned by bees, can carry infection. Only a few bees may contract infection in the autumn from these faeces, but they join the winter cluster and initiate the next outbreak of the disease. Transferring a colony on to clean comb early in the spring or summer removes the source of the disease, and it...

The epizootiology of european foulbrood of the larval honey bee, Apis mellifera Linnaeus National Institute of Agronomic Research
Bailey, L..
Larvae, artificially infected when 0 to 1 day old with Streptococcus pluton (White) and placed in colonies, were usually ejected by adult bees. Ejection was delayed from colonies deprived either of unsealed brood or their queen, or which were reinforced with adult bees. The feces of surviving larvae whose weight was subnormal, contained many viable cells of S. pluton. Colonies reinforced with unsealed brood removed more infected larvae than usual. It is concluded that infected larvae are ejected when larval food is merely adequate, as it may be when a colony is growing rapidly ; and they are kept when larval food is more abundant, as it may be when brood rearing is retarded. Natural outbreaks of disease occurred when brood-rearing, in colonies heavily...
