Summary

A method for in vitro cultivation of teratocytes from the egg parasitoidTelenomus heliothidis (Hymenoptera: Scelionidae) is described. Parasitoid eggs, from which teratocytes were derived, were collected from 24-h-oldHeliothis virescens (Lepidoptera: Noctuidae) eggs previously parasitized byT. heliothidis females. Optimal culture conditions, including species and concentration of serum, were determined experimentally. Thirty percentManduca sexta hemolymph or 10% chicken serum in Hink’s TNH-FH medium were found to generate the most satisfactory number of teratocytes per parasitoid larva. Teratocytes cultivated in vitro showed similar development and morphology to those produced in vivo. However, cultured teratocytes lived approximately 10 times longer than teratocytes in natural hosts and were not dependent upon the presence of the parasitoid larva for normal development.
