Abstract

Six species of ectoparasitic nematodes – Xiphinema brevicolle, Xiphinema gr. americanum, Xiphinema incertum, Xiphinema pachtaicum, Xiphinema vuittenezi, Xiphinema species (Longidoridae) and 2 species of endoparasitic nematodes – Pratylenchus penetrans and Pratylenchus sp. (Hoplolaimidae) have been ascertained. Xiphinema pachtaicum and Pratylenchus penetrans seem to be dangerous pests of apricot.
They have been observed as the most dominant species in the rizosphere of die back and completely died trees on apricot rootstocks, wild plum (Janka 4) and Myrobolan in the region of Silistra.
Up to 5790 specimens of Xiphinema pachtaicum and 355 specimens in 100 cm³ of soil of Pratylenchus penetrans were counted in 100 cm³ of soil.
