Meloidogyne incognita wartellei n. subsp. (Meloidogynidae), a Root-knot Nematode on Resistant Soybeans in Louisiana.
Meloidogyne incognita wartellei n. subsp, is described and illustrated from roots of soybean (Glycine max L.) near Washington, Louisiana. It is rather limited in distribution in that state, being known at five locations comprising about 60,000 acres. It not only attacks commonly susceptihle soybeans but is a destructive pest on other commercial soybean varieties that are resistant to other form...
متن کاملDescription of Pratylenchoides camachoi n. sp. (Tylenchida: Pratylenchidae) from Spain.
Pratylenchoides camachoi n. sp. from rosemary (Rosmarinus officinalis L.) in Sierra De Cazorla in southeastern Spain is described and illustrated. Pratylenchoides camachoi n. sp. is a bisexual species characterized by a cylindroid, sometimes clavate-shaped, male tail with a uniquely shaped smooth, rounded terminus. Females are characterized by a short esophageal overlap and six lines in the lat...
متن کاملArbuscular mycorrhizal colonization of tomato by Gigaspora and Glomus species in the presence of root flavonoids.
The effect of flavonoids isolated from arbuscular mycorrhizal (AM) colonized and noncolonized clover roots on the number of entry points and percentage of root colonization of tomato (Lycopersicum esculentum L.) by Gigaspora rosea, Gi margarita, Glomus mosseae and G. intrarradices symbionts was determined. With fungi of both genera, a correlation between the number of entry points and the perce...
متن کاملScanning Electron Microscope Study of the Root-knot Nematode (Meloidogyne incognita) on Tomato Root.
This study examines the types of structural information that can be gained by utilizing the scanning electron microscope (SEM) and a cryofracture technique to examine the host-parasite interaction. Roots of tomato, Lycopersicon esculentum cv. Marglobe, were cultured aseptically and inoculated with the root-knot nematode, Meloidogyne incognita. Twenty-four hours to four weeks after inoculation, ...
متن کاملEffect of Meloidogyne incognita on Reproduction of Pratylenchus penetrans in Red Clover and Alfalfa.
Roots of seedlings of red clover and alfalfa growing on 10(1) Hoagland and Arnon solution agar were inoculated with various combinations of Meloidogyne incognita and Pratylenchus penetrans. Egg-laying by P. penetrans decreased as the number of nematodes, the ratio of entrant M. incognita to entrant P. penetrans, and the priority of invasion of roots by M. incognita increased. Embryogeny and hat...
