Caudal Papillae in Romanomermis culicivorax

Ganpat B. Jagdale, Roger Gordon

Abstract


Distribution of caudal papillae in adult Romanomermis culicivorax was determined by scanning electron microscopy. Ninety eight caudal papillae, each containing one pore, were present in males but absent in females. Papillae were arranged in three longitudinal rows, one ventral, two ventrolateral; the middle ventral row bifurcated anterior to the spicule. The appearance of the papillae was different anterior and posterior to the spicule. The role of the caudal papillae in mediating copulatory behavior was discussed. Key words: caudal papillae, nematode, Romanomermis culicivorax, scanning electron microscopy.
