Host Status of Different Bermudagrasses (Cynodon spp.) for the Sting Nematode, Belonolaimus longicaudatus.
Thirty-seven warm-season bermudagrass (Cynodon spp.) accessions, two cool-season grasses (Lolium perenne and Festuca arundinacea), 'Transvala' digitgrass (Digitaria decumbens), and Sorghum bicolor were evaluated to determine host suitability and susceptibility to the sting nematode, B. longicaudatus, in a 140-day microcell bioassay. All seven of the evaluated commercial cultivars of Cynodon wer...
متن کاملVariation among Populations of Belonolaimus longicaudatus.
Three North Carolina populations of Belonolairnus longicaudatus differed significantly from three Georgia populations in stylet measurements, the c ratio, the distance of the excretory pore from the anterior end for both sexes; the a ratio for females only; and the total body length, tail length, and spicule length for males only. The Georgia nematodes were stouter, and the females possessed sc...
متن کاملUltrastructure and Development of Pasteuria sp. (S-1 strain), an Obligate Endoparasite of Belonolaimus longicaudatus (Nemata: Tylenchida).
Pasteuria sp., strain S-1, is a gram-positive, obligate endoparasitic bacterium that uses the phytoparasitic sting nematode, Belonolaimus longicaudatus, as its host in Florida. The host attachment of S-1 appears to be specific to the genus Belonolaimus with development occurring only in juveniles and adults of B. longicaudatus. This bacterium is characterized from other described species of Pas...

متن کاملThe internal transcribed spacer region of belonolaimus (nemata: belonolaimidae).
Belonolaimus isolates from six U.S. states were compared by restriction endonuclease digestion of amplified first internal transcribed spacer region (ITS1) of the nuclear ribosomal genes. Seven restriction enzymes were selected for evaluation based on restriction sites inferred from the nucleotide sequence of a South Carolina Belonolaimus isolate. Amplified product size from individuals of each...
