The citrus nematode Tylenchulus semipenetrans (Cobb, 1913) (Tylenchida: Tylenchulidae) is one of the most important plant-parasitic nematodes that infects citrus orchards. This nematode was detected in several parts of Turkey. Citrus orchards were severely infested by T. semipenetrans in the Mediterranean (Adana, Mersin, Hatay, Osmaniye) and Aegean (İzmir, Aydın) regions. It was found at different population densities and race in citrus, olive, and grape. Control methods are applied such as quarantine, nematicides, and resistant rootstocks in Turkey. One of the best control methods is using resistant rootstocks because this is eco-friendly and affordable. Until now, the rootstocks of Tuzcu 31-30T, Nasnaran, Poncirus trifoliata, Cleopatra ant, Local trifoliate Cloex swingle, Citrumelo 4475, C-35, Gou tou, Sunki, Tuzcu 891, Carrizo citrange were found resistant. Tylenchulus semipenetrans is more common than it was thought to be in Turkey and the population fluctuations change according to age and variety of the citrus rootstocks in citrus orchards.
