Abstract

Nematodlar, tarımsal ürünlerde kayıplara yol açan en önemli zararlılardan birisidir. Nematodlar, genel olarak bitki köklerinde beslenerek direk oluşturdukları zarar yanında çok sayıda bitki virüslerine vektörlük yaparak da dolaylı olarak tarımsal ürünlerde verim kayıplarına yol açmaktadır. Bu nematodlar, Longidoridae ve Trichodoridae familyalarına bağlıdır ve nepo ve tobravirus cinslerine ait virüsleri nakletmektedir. Tobravirüsler Trichodorus ve Paratrichodorus cinslerine ait türler ile, Nepovirüsler ise Longidorus ve Xiphinema cinslerine ait nematod türleri ile taşınmaktadır.

TRANSMISSION OF PLANT PATHOGENIC VIRUSES BY PLANT PARASITIC NEMATODES

Abstract

Nematodes are one of the most importent pests causing yield losses to agricultural crops. Nematodes generally cause direct damage by feeding on plant roots, and indirectly by transmitting viruses. These nematodes belong to the families Longidoridae and Trichodoridae, and transmit viruses belonging, respectively, to the genera Nepovirus and Tobravirus. Tobraviruses transmission is carried out by nematodes belonging to the genera Trichodorus and Paratrichodorus, Nepoviruses are transmitted longidorid nematodes of the genera Longidorus or Xiphinema.
