The specific gravity of spores of Pasteuria penetrans collected from Meloidogyne arenaria was found to be around 1.28. Increasing the sucrose concentration used for the extraction of Pratylenchus scribneri from a specific gravity of 1.14 to 1.26 led to the recovery of higher numbers of specimens filled with spores of Pasteuria sp. (P </= 0.05). The numbers of spore-filled specimens of Hoplolaim...

A survey of plant parasitic nematodes associated with Zea mays in Kashmir valley was conducted from June 2006 to November 2006 which yielded a number of Tylenchids. Among them, the species Tylenchorhynchus zeae Sethi and G. Swarp, 1968, Pratylenchus sativus kaul, 1985, Aphelenchoides srinagrensisKaul, 1985 are reported herein, with dimensions. The parasites are being recorded for the first time...

Frozen hydrated specimens of Pratylenchus agilis and dauer larvae of Steinernema carpocapsae were observed with low-temperature field emission scanning electron microscopy. This new technique provides information about the surface features of nematodes and also allows specimens to be fractured to reveal their internal structure. Furthermore, both halves of fractured specimens can be retained, e...
