Abstract
Symbiotic bacteria have been found in cytoplasm and in nucleus of the oocytes from all developmental stages and trophocytes of periovarial fat bodies of supplementary reproductives and nymphs of Reticulitemles lucifugus (Isoptera: Rhinotermitidae). The bacteria resemble intracellular symbionts found in other insect species. The presence of bacteria in the gut lumen of fully developed embryos and "pharate" larvae suggest a transovarial transmission of intracellular symbionts (endocytobionts) in R. lucifugus. This transovarial transmission does not appear to be correlated with presence and differentiation of specialized cells such as bacteriocytesI documenti in SFERA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
