Life Cycle and Mating Behavior of Zygotylenchus guevarai (Nematoda: Pratylenchidae) on Excised Petroselinum crispum Roots

Mehmet Karakas

Abstract:
The life cycle and mating behavior of Zygotylenchus guevarai were observed in vitro on excised roots of Petroselinum crispum in gnotobiotic culture. Eggs hatched into juveniles whose appearance and structure were similar to those of the adults. Juveniles grew in size and each juvenile stage was terminated by a molt. Z. guevarai had four juvenile stages with the first molt occurred outside the egg shortly after hatching. After the final molt the juveniles differentiated into adult males and females. Mating was required for reproduction. After mating, fertilized females began to lay eggs. The life cycle from second stage juvenile to second stage juvenile was completed in 43 days.
