Abstract
Vitellogenins are the major yolk proteins, synthesized in the fat body, released into the hemolymph and captured by the developing oocytes, but the mechanisms by which these proteins cross the follicular cell layer are still poorly understood. This study describes the actin distribution in follicular cells during vitellogenin transport to the oocyte in social Hymenoptera represented by bees Apis mellifera and Melipona quadrifasciata, the wasp Mischocyttarus cassununga and the ant Pachycondyla curvinodis. In oocytic chambers of vitellogenic follicles, vitellogenin was found within the follicular cells, perivitelline space and oocyte, indicating a transcellular route from the hemolymph to the perivitelline space. The cortical actin cytoskeleton in follicular cells underwent reorganization during transport of vitellogenin across this epithelium suggesting that in the ovary of social hymenopterans, vitellogenin delivery to oocytes requires a dynamic cytoskeletal rearrangement of actin filaments in the follicular cells.

Abstract
In the honey bee, vitellogenin has several functions in addition to egg provisioning. Among others, it serves as a precursor to brood food proteins secreted by the hypopharyngeal glands of worker bees. In queenless workers with developing gonads, oogenesis and development of the hypopharyngeal glands are correlated. Here we describe two experiments that explored whether this relationship also exists in non-reproductive workers, and investigated a possible role of ecdysteroid hormones in the regulation of vitellogenin uptake. In the first experiment, the correlation between oocyte length and hypopharyngeal gland development was measured in workers before and after de-queening. In the second experiment, we induced middle-aged bees with resting glands to suddenly initiate brood care behaviour, and measured haemolymph ecdysteroid and vitellogenin titres. A strong positive relationship existed between morphometrical parameters of hypopharyngeal glands and ovaries in both queenless and queenright (functionally sterile) workers. No response of ecdysteroid titres to the addition of brood was detected in experiment 2, but high concentrations were measured in a small group of bees characterised by the possession of oocytes on the brink of yolk incorporation. We conclude that hypopharyngeal glands may belong to a previously described group of reproduction-related traits that are pleiotropically regulated in workers. A possible role for ecdysteroids in honey bee reproduction is discussed.

Abstract
Neither the overall differences in ovariole number nor the caste-specifically modulated expression of vitellogenin can fully explain the striking caste differences in honey bee reproduction, in particular the mechanisms that block oogenesis in virgin queens and in workers kept in the presence of a queen. For this reason we investigated the initial stages of oogenesis in queens in relation to mating status and in workers exposed to different social conditions. A striking feature in ovarioles of both castes was a considerably elongated terminal filament which consisted not only of normal terminal filament cells but also contained apparently undifferentiated cells that were tentatively considered as stem cells. BrdU incorporation was detected in the upper germarium, as well as in the terminal filament. Cytoskeleton analysis by TRITC-phalloidin labeling for F-actin, and immunofluorescence detection for beta-tubulin did not reveal structural differences in the early oogenesis steps between queens and queenless workers. In contrast, queenright workers showed signs of a disorganized microtubule and microfilament system that could explain the histological evidence for progressive cell death observed in the germaria. In addition to cytoplasmic tubulin we also detected marked intranuclear foci indicating the presence of nuclear beta(II)-tubulin.

Abstract
Insect eggs are giant and very complex cells covered by an extremely resistant shell. Both the egg cell and surrounding eggshell express anteroposterior and ventrodorsal polarity. The molecular and cytoplasmic organization of both axes originates during oogenesis and leads to the production of an ooplasmic system which consists of euplasm and deutoplasm (yolk) and contains a nucleus as well as extranuclear determinants of maternal origin. Both are part of the store of information for early embryogenesis. In addition, the deutoplasm serves as raw material and early nutrient supply for building the embryo. The insect egg cell, which is arrested in the first maturation division when released from the ovary during oviposition, will be activated by different stimuli among different species to complete meiosis and start embryogenesis. The zygote nucleus undergoes a number of synchronous mitotic divisions leading to cleavage energids which initially form a syncytial blastoderm and subsequently the cellular blastoderm. In many insects, prior to blastoderm formation, polar granules (or oosome material) are incorporated in a single cell or a small number of cells which bud off at the posterior pole. These so called pole cells give rise to the primordial germ cells. Therefore, polar granules or the oosome material mark the germ line, and while structural counterparts of determinants of body pattern formation have so far not been found, the polar granules or oosome serve as an autonomous ooplasmic determinant for the pole or germ cells. Anteroposterior body polarity can arise independent of the germ plasm.

Abstract
Shortly after subcutaneous or intraperitoneal injection of nontoxic quantities of trypan blue into laying Japanese quails, red fluorescent yolk granules appear in the peripheral ooplasm of their oocytes at the end of the lampbrush stage or subsequently. Later a red fluorescence can be observed in the apical cytoplasm of the granulosa cells. The results obtained by this method confirm our previous results (Callebaut 1979) obtained by autoradiography after 3H-leucine administration and furnish interesting additional data. The trypan blue-induced fluorescence method gives a good indication of the permeability of the oocytal cortex and its derivative the germinal disc. The avian yolk which is, or has been peripherally assembled (primordial, true white and yellow yolk) can be characteristically labelled by the administration of trypan blue. The injection of higher, still nontoxic quantities of trypan blue has a prolonged "retarding" effect and permits the marking of a broader part of the germinal disc or eventually of the blastoderm which develops from it.

Abstract
It was shown that the vital dye trypan blue injected subcutaneously is adsorbed on exogenous yolk and stored in oocytes of Japanese quails. The binding sites of the dye could be visualized by fluorescence microscopy. The spectral distribution of the trypan blue-induced fluorescence emitted by yolk granules was analyzed microspectrographically. The analysis revealed that yolk granules exhibit a deep red fluorescence radiation with a maximum intensity at 670 nm, when blue or green excitation light is used. This fluorescence was exclusively induce by the presence of trypan blue, and not by contaminants of the dye. The fluorescence intensity did not decrease during processing of the tissue throughout the different solvents routinely used in light microscopy, especially after fixation in Heidenhain's fluid, nor did it suffer from pronounced fading during irradiation of the tissue. Model experiments showed that the value of the fluorescence emission maximum was concentration-dependent, and that amounts as little as 5 x 10(-3) mg trypan blue per ml solution containing an excess of yolk as a substrate for the dye, could clearly be detected and measured. It is suggested that a highly diluted solution of trypan blue can be used without teratogenic effects, as a tracer for exogenous yolk uptake and migration into oocytes, and that fluorescence microscopy is a reliable method for its further localization. A detailed account of the procedure is reported.
