Heterodera raskii n. sp. is described and illustrated from specimens collected from roots of bulb grass, Cyperus bulbosus, in Hyderabad, India. The new species belongs to the 'goettingiana' group and differs from closely related H. cyperi by the elongate ovoid shaped cysts and females, greater fenestral length, width, vulval slit, and absence of egg sac. The stylet knob shape was round in second-stage juveniles and posteriorly sloping in females and males of H. raskii n. sp., while it was… 

New Species of Cyst Nematode Heterodera pakistanensis (Nematoda: Heteroderidae) Attacking Wheat in Pakistan.

Second-stage juveniles of Heterodera pakistanensis can be distinguished from H. cyperi J2 by an areolated lateral field with four incisures and shorter stylet, whereas cysts are separated by a more elongated vulva slit and the conspicuous structure of the underbridge.

SEM Observations and Morphometrics of the Cabbage Cyst Nematode, Heterodera cruciferae Franklin, 1945, Collected Where Brassica spp. Are Grown in Tabriz, Iran

During a survey of plant parasitic nematode biodiversity in vegetable fields of Tabriz, East Azerbaijan province, Iran between 2004 and 2005, 25 species belonging to 16 genera of nematodes were

Cyst Nematodes in Equatorial and Hot Tropical Regions

In the present communication, the term “cyst nematodes in equatorial and tropical regions” is used instead of the usual “tropical cyst Nematodes” for two reasons: the topographical meaning of “intertropical” encompasses some mountainous areas, namely in Central and South America, where climate, vegetation and crops are quite similar to those of temperate regions.

Effects of root diffusates of some weeds associated with corn plantations on the hatchability of the corn cyst nematode,Heterodera zeae

All tested weed root diffusates (WRD) successfully stimulated the hatchability of the cysts, but less than CRD did except the root diffuates (RD) ofRumex dentatus which failed to stimulate the nematode cysts.

Taxonomy and identification

This chapter is on microtaxonomy, including the classification and identification of cyst-forming nematode, which was covered for cyst nematodes in chapter 3.
