Abstract
The postembryonic development of Romanomermis culicivorax was studied in experimentally infected Aedes aegypti larvae. During its 7-day parasitic phase the nematode increased 8-fold in length and 10-fold in width, and the number of somatic nuclei increased 30-fold. Mitosis was observed in the hypodermal, trophosomal (intestinal), and muscle tissues. Body length and body width were correlated with number of somatic nuclei (r = +0.95, p < 0.001 and r = +0.91, p < 0.001 respectively). Growth in R. culicivorax is associated with extensive nuclear division, and this is believed to be the first report of accretionary growth in nematodes. The number of lateral hypodermal chord nuclei is variable in postparasitic juveniles and adults (mean, 1206 ± 536; range, 610–2475) and is correlated with body length (r = +0.84, p < 0.001). The lateral hypodermal chord nuclei do not undergo a fixed number of divisions.
