Dynamics of bacteriocyte structures during aphid aging.

Comparison of hematoxylin and eosin stainings performed on parthenogenetic N3 nymph (a,c) and A23 senescent adult (b,d) sections. The top panels (a,b) show the general organization of the bacteriocyte structures in the aphid abdomen. Red and blue dotted lines outline the clustering of bacteriocytes into two regular structures surrounded by the embryonic chains, in nymphs and the degenerating bacteriocyte structures, in senescent aphids, respectively. The bottom panels (c,d) show representative bacteriocyte cells. Arrowheads show low symbiont-density zones in degenerating bacteriocytes. Scale bars = 200 μm (a,b) or 50 μm (c,d).
