Triglycerides are converted to diglycerides in fat body cells (trophocytes), which in turn are attached to lipophorins prior to entering hemolymph for transport (Bailey 1975).
nigrispinus has ovary of meroistic type (LEMOS et al., 2005), with nutritive cells known as nurse cells or trophocytes, which supply metabolites and organelles through cytoplasmic bridges to oocytes.
In this ovary type, once the mitotic proliferation phase of the secondary oogonia or cytoblast is over, one cell of the resulting clone differentiates into the oocyte while the other cells remain as nurse cells, or trophocytes. The ovarian follicles present in the vitellarium are divided into two interconnected chambers, the oocytic chamber that contains the oocyte and is located proximally to the nurse chamber that contains the trophocytes or nurse cells.
gregaria are of panoistic type; i.e., the feeder trophocytes are absent and the follicular base is the only trophic tissue (Launois-Luong 1978).
