Plant parasitic nematodes in new jersey.
the number of bacteria per dauerjuvenile. Preliminary data established similar LD50s and LT50s for X. nematophilus subsp, nematophilus (from the DD 136 strain) and X. nematophilus subsp, nematophilus vat. mexicanus (from the Mexican strain). The absence of toxin production by either S.feltiae strain or bacterial types in a culture medium similar to the host's hemolymph has been reported (5,6). ...
متن کاملNew trends in managing plant parasitic nematodes-introductory remarks.
The late 1980s and early 1990s should prove to be a most exciting period in the development and application of nematode management technologies. Many opportunities exist in developing new nematode management tools. These tools are most likely to be developed under one or more of the following: biotechnology, biocontrol, environmental manipulation, allelopathy, semiochemicals, and improved nemat...
متن کاملAtomic force microscopy of plant-parasitic nematodes.
A simple method for atomic force microscopy (AFM) of nematode cuticle was developed to visualize the external topography of Helicotylenchus lobus, Meloidogyne javanica, M. incognita, and Xiphinema diversicaudatum. Endospores of two isolates of the nematode parasite, Pasteuria penetrans, adhering to M. incognita and X. diversicaudatum were also visualized and measured by this technique. Scanning...
متن کاملSpatial pattern analysis of plant-parasitic nematodes.
Spatial patterns of Meloidogyne incognita, Tylenchorhynchus claytoni, Helicotylenchus dihystera, and Criconemella ornata were analyzed using Hill's two-term local quadrat variance method (TTLQV), spectral analysis, and spatial correlation. Data were collected according to a systematic grid sampling plan from seven tobacco fields in North Carolina. Different estimates of nematode cluster size we...
متن کاملFungal egg-parasites of plant-parasitic nematodes from Spanish soils.
We have investigated the presence of fungal egg-parasites in Spanish soils with plant endoparasitic nematodes. Nine out of 68 samples (13%) yielded fungal parasites. The most common (seven strains) was Pochonia chlamydosporia var. chlamydosporia (= Verticillium chlamydosporium var. chlamydosporium), but Lecanicillium lecanii (= Verticillium lecanii) and Paecilomyces lilacinus were also found. M...
