Abstract
Trichodorus christiei eggs were laid in the single cell stage. The first two cleavages were transverse to the longitudinal axis of the egg, forming four blastomeres of similar size. Metaphase chromosomes were approximately 3 μ in length. First-stage juveniles were recognizable after 96 hours, and emerged from the egg 100–120 hours after it was laid. Stomatal armature was well developed after 96 hours. The esophagus and intestine developed shortly before emergence.Keywords
