“…specimens of Cinara cedri (Lachnidae) from Chile do not possess secondary endosymbionts, while European specimens of this species harbour an obligate secondary symbiont Serratia symbiotica (Perez-Brocal et al, 2006;Burke et al, 2009). Previous and present ultrastructural observations indicate that the secondary endosymbionts in the aphids studied always occur in bacteriocytes (Hinde, 1971;Griffiths & Beck, 1975;Brough & Dixon, 1990;Akhtar & van Emden, 1994;Pyka-Fosciak & Szklarzewicz, 2008;this study). As a rule, these bacteria are harboured in their own bacteriocytes.…”

“…In contrast to primary and secondary endosymbionts, these bacteria do not have own bacteriocytes and are very sparse. It should be noted that three types of endosymbionts are recorded in several other representatives of the family Lachnidae (Klevenhusen, 1927;Buchner, 1965;Gomez-Valero et al, 2004;Pyka-Fosciak, 2006;Pyka-Fosciak & Szklarzewicz, 2008;Burke et al, 2009). The localization of the third type of microorganism in species of lachnid varies, e.g.…”

“…Within hemipterans scale insects exhibit the greatest diversity of modes of transovarial transmission of endosymbionts (Buchner, 1965(Buchner, , 1966(Buchner, , 1967Szklarzewicz et al, 2006Szklarzewicz et al, , 2010Szklarzewicz et al, , 2013Niżnik & Szklarzewicz, 2007). Observations on the behaviour of endosymbiont in aphids (Buchner, 1965;Braendle et al, 2003;Miura et al, 2003;Wilkinson et al, 2003;Pyka-Fosciak & Szklarzewicz, 2008;Koga et al, 2012) have shown that these insects unlike other hemipterans are characterized by a rather uniform mode of transmission of microorganisms from mother to offspring. In all the viviparous females studied the bacteria invade embryos at the blastula stage.…”

Abstract. The ultrastructure, distribution and transovarial transmission of endosymbiotic bacteria in representatives of six aphid families: Eriosomatidae (Pemphigus spyrothecae, Prociphilus fraxini), Anoeciidae [Anoecia (Anoecia) corni], Drepanosiphidae [Mindarus abietinus, Sipha (Rungsia) maydis, Clethrobius comes, Myzocallis (Lineomyzocallis) walshii], Thelaxidae (Thelaxes dryophila), Aphididae (Delphiniobium junackianum, Aphis viburni, Cavariella theobaldi, Macrosiphoniella tanacetaria) and Lachnidae (Schizolachnus pineti, Eulachnus rileyi) were studied at the ultrastructural level. The ovaries of aphids are accompanied by large organs termed bacteriomes that consist of giant cells termed bacteriocytes. The bacteriocyte cytoplasm is tightly packed with endosymbiotic bacteria. Ultrastructural observations have shown that the bacteria Buchnera aphidicola (primary symbiont of aphids) present in various species are characterized by significant differences in both size and organization of their cytoplasm. In the aphids, Prociphilus fraxini, Sipha (Rungsia) maydis, Thelaxes dryophila, Aphis viburni, Cavariella theobaldi, Macrosiphoniella tanacetaria, Eulachnus rileyi and Schizolachnus pineti, in addition to Buchnera aphidicola, secondary endosymbionts are also present. The bacteriocytes containing secondary endosymbionts are less numerous than those with Buchnera. In Eulachnus rileyi (Lachnidae), in addition to primary and secondary endosymbionts, there is a third type of microorganism. In all species examined both the primary and secondary endosymbionts are transovarially transmitted from mother to offspring.

This article covers the origin and development of scientific interest in insect and amphibian developmental biology at the Department of Systematic Zoology and Zoogeography of the Jagiellonian University. The greater part of this historical account is devoted to Professor Stanislaw Smreczynski (1899-1975), the founding father of the Department, and comments on his biography and research achievements in the field of animal experimental embryology. A particular emphasis is on Smreczynski's contributions to contemporary understanding of early embryonic development of amphibians and insects as well as his expertise in Pleistocene and extant weevils (Curculionidae). A concise survey of developmental phenomena studied by some of Smreczynski's co-workers and followers is also presented, including the early embryogenesis of entognathans as well as germ cell determination and gonad formation in Drosophila virilis conducted by Jura; analysis of oogenesis in Collembola carried out by Krzysztofowicz; investigations of insects and tradigrades by Weglarska, and finally research into various aspects of ovary structure in diverse insect taxa by the Bilinski group.

The organization of the egg capsule of the euholognathan stonefly, which represents the family Taeniopterygidae (Nemuroidea) was investigated using light and electron microscopy techniques. The presence of a complex, multilayered egg capsule, composed of a vitelline envelope, multilayered chorion, and extrachorion is described. The morphology of the eggshell of Brachyptera risi was compared with that of euholognthan and systellognathan egg coverings and the ground plan of the egg capsule in Plecoptera was discussed.
