Abstract :Abstract The life cycle and mating behavior of Zygotylenchus guevarai were observed in vitro on excised roots of Pisum sativum in gnotobiotic culture. Eggs hatched into larvae whose appearance and structure were similar to those of the adults. Larvae grew in size and each larva stage was terminated by a molt. Z. guevarai had four larva stages with the first molt occurred outside the egg shortly after hatching. After the final molt the larvae 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 larva to second stage larva was completed in 39 days.   Key Words: Zygotylenchus guevarai, root lesion nematode, gnotobiotic culture, life cycle, mating behavior   Kesilmiş Pisum sativum Köklerinde Zygotylenchus guevarai insert ignore into journalissuearticles values(Nematoda: Pratylenchidae); nin Hayat Devri ve Çiftleşme Davranışı   Özet Zygotylenchus guevarai ’nin hayat devri ve çiftleşme davranışı gnotobiotik kültürde Pisum sativum ’un kesilmiş köklerinde in vitro olarak gözlenmiştir. Yumurtadan çıkan larvalar görünüş ve yapı olarak erginlere benzerlik göstermiştir. Büyümüş larvaların her bir gelişim safhası deri değişimi ile sonlanmıştır. Dört larva safhasına sahip Z. guevarai ’de birinci deri değişimi yumurta dışında meydana gelmiştir. Son deri değişiminden sonra larvalar, ergin erkek ve dişilere farklılaşmışlardır. Çiftleşmenin üreme için gerekli olduğu gözlenmiştir. Çiftleşmeden sonra dişiler döllenmiş yumurtalarını bırakmıştır. Hayat devri ikinci devre larvadan, ikinci devre larvaya 39 günde tamamlanmıştır.   Anahtar Kelimeler: Zygotylenchus guevarai, kök lezyon nematodu, gnotobiotik kültür, hayat devri, çiftleşme davranışı
