Although we have not demonstrated that trypan blue becomes incorporated into membrane bound yolk spheres as does Vg, it is reasonable to assume that this is the case since only terminal follicles in each ovariole sequester the dye and since the dye colocalizes with Vg in the spaces between follicle cells (Fig.
Vitellogenesis, yolk formation in developing oocytes, consists of two processes in insects: vitellogenin (Vg) production by the fat body and Vg uptake by terminal follicles within ovarioles of vitellogenic ovaries.

That trypan blue injection is an efficacious way to survey entire ovaries for the incidence of vitellogenic follicles is shown in Figure 2 (top) where several ovarioles have been teased away from an ovary removed from an injected animal and then viewed with a dissecting microscope.
Ovariole length correlated with egg load (n = 10, r = 0.
Using wasps of the Bolivian stock from Alachua County, Florida, we determined the structure of the wasp's ovaries and ovarioles in order to assess potential fecundity.
