Head Morphology of Second-Stage Juveniles of Some Heteroderidae (Nematoda: Tylenchoidea)
Nematologica, 1975 Scanning electron microscope observations of heads of second stage juveniles of five of the genera of the Heteroderidae are described and the systematic significance of the different forms discussed. Within the genus Heterodera differences in head morphology generally accord with the recognised sub-divisions of the genus.

Journal of nematology, 2012 The cellular architecture of the female gonoduct of 68 nematode populations representing 42 species belonging to Tylenchidae, Belonolaimidae, Hoplolaimidae and Meloinema is shown to have an overall similarity in cellular gonoduct structure. The oviduct consists of two rows of four cells; the spermatheca is comprised of 10 to 20 cells, and the uterus ...

Journal of nematology, 2011 The family Heteroderidae, its two subfamilies Heteroderinae and Meloidogyninae and the nominal genera of Heteroderinae (Heterodera Schmidt, 1871; Meloidodera Chitwood, Hannon &Esser, 1956; and Cryphodera Colbran, 1966) are rediagnosed. Meloidoderita Pogosyan, 1966 is considered a genus inquirenda.

Revision of the genus nacobbus thorne and allen, 1944 (nematoda: tylenchoidea).
Journal of nematology, 2011 All four species and one subspecies of the genus Nacobbus Thorne and Allen, 1944 were studied and measured from type specimens. Nacobbus batatiformis Thorne and Schuster, 1956; N. serendipiticus Franklin, 1959; and N. serendipiticus bolivianus Lordello, Zamith and Boock, 1961 are proposed as synonyms of N. aberrans (Thorne, 1935) Tborne and Allen, 1944.

Embryology and Life Cycle of Tylenchorhynchus claytoni Steiner, 1937 (Nematoda: Tylenchoidea).
Journal of nematology, 2011 Development of Tylenchorhynchus claytoni from unsegmented egg to hatching takes 135 hr at 22-25 C. The fourth molt lasts 5 to 6 days. During exsheathment the cast cuticle of the larva separated into two unequal parts, breaking near either the anterior or posterior end.
