Figure 3

Lateral left view (anterior to left) differential interference contrast (DIC) micrograph (top) and with transparent color overlay (bottom) of a 96 HET female Steinernema carpocapsae gonad posterior arm. The gonad morphology at 96 HET is similar to that seen at 72 HET. However, by 96 HET, numerous fertilized embryos are seen in the uterus (red). The spermathecal-uterine complex (green) is located at the farthest point away from the mid-body and contains a single oocyte (inset) surrounded by numerous sperm (arrowhead). The ovary (blue) is much longer than in 72 HET females, frequently extending beyond the mid-body plane. In this image, the distal tip cell of the anterior gonad arm (arrow) extends into the posterior half of the female. Scale bars, 50 µm (main figure) 10 µm (inset).
