| structure of the ovaries and oogenesis in cixius nervosus (cixiidae), javesella pellucida and conomelus anceps (delphacidae) (insecta, hemiptera, fulgoromorpha). | ovary organization in representatives of two families of fulgoromorpha, cixiidae (cixius nervosus) and delphacidae (javesella pellucida and conomelus anceps), was examined by light and transmission electron microscopy. ovaries of studied fulgoromorphans consist of telotrophic ovarioles. from apex to base individual ovarioles have four well defined regions: a terminal filament, tropharium (trophic chamber), vitellarium and pedicel (ovariolar stalk). tropharia are not differentiated into distinct ... | 2007 | 18089099 |
| the auchenorrhyncha fauna of peat bogs in the austrian part of the bohemian forest (insecta, hemiptera). | the first overview on the auchenorrhyncha fauna of peat bogs of the austrian bohemian forest is presented. seven oligotrophic peat bog sites were studied in 2011 by suction sampler ("g-vac") and 93 auchenorrhyncha species (with 7465 adult specimens) were recorded. eleven species (about 18 % of the individuals) are tyrphobiontic or tyrphophilous. the relative species abundance plot is not very steep; the six most abundant species represent 50 % of the individuals. the most common species is conom ... | 2013 | 24039517 |
| ultrastructure and transovarial transmission of endosymbiotic microorganisms in conomelus anceps and metcalfa pruinosa (insecta, hemiptera, fulgoromorpha). | endosymbiotic microorganisms commonly occur in fulgoromorphans, as in other plant sap-sucking hemipterans. large syncytial organs termed mycetomes are present in the body cavities of conomelus anceps (delphacidae) and metcalfa pruinosa (flatidae), in the close vicinity of the ovaries. the mycetomes are surrounded by a one-layered epithelium. the mycetome cytoplasm is filled with yeast-like symbiotic microorganisms (ylss). the ylss are transovarially transmitted to the next generation. the endosy ... | 2009 | 19777955 |
