Criconemella spp. in Pennsylvania Peach Orchards with Morphological Observations of C. curvata and C. ornata
AbstractCriconemella xenoplax and C. curvata, previously associated with decline of peach trees in other parts of the United States, were found in 20 of 25 Pennsylvania peach orchards. Population densities were high in some samples. Morphometrics of juveniles and adult females of Criconemella curvata and C. ornata, are provided. Cuticular crenations were observed on J2 and J3 stages of C. curvata and J2-J4 stages of C. ornata. Key words: Criconemella curvata, C. ornata, C. xenoplax, Hirsutella rhossiliensis, morphometrics, peach decline, ring nematode.
