brenani), and also the stylet and spicule have been longer (13 mm and 32-34 mm vs. ten mm and 25-26 mm). Male and J2 tail tipsMeeting Abstracts 453 have been rounded inside the undescribed species but MK-8776 web sharply pointed in S. brenani juveniles weren't described. The undescribed species resembles Subanguina askenasyi, also described from H. cupressiforme, but doubt exists in regards to the limits of this species. Inside the original description Butschli stated that female and male lengths were 1.7 mm and 1.four mm, respectively, but Steiner gave lengths of 0.98-1.two mm and 0.92-1.two mm, with a stylet length in each sexes of ten mm. Regardless of the similarity in measurements it really is unlikely that Steiner's specimens will be the exact same taxon because the undescribed species, due to the fact stylet length is distinct. Moreover, the tail guidelines of Steiner's specimens are sharply pointed, whereas within the undescribed species they are rounded. Separation of Anguina from Subanguina is dependent around the structure with the female reproductive program. Additional specimens, especially of live, gravid females, are necessary to study morphology from the gonad for definitive placement in Anguina or Subanguina. NON-DESTRUCTIVE X-RAY IMAGING OF ROOT SYSTEMS INFECTED WITH ENDOPARASITIC NEMATODES. Bernard, Ernest C.1, D.W. McDonald2, R. Michaels2, and B.H. Ownley1. 1Entomology and Plant Pathology Dept., University of Tennessee, 2431 Joe Johnson Drive, Space 205, Knoxville, TN 37996-4500; and 2Phenotype Screening Corp., Suite 10, 4028 Papermill Rd., Knoxville, TN 37909. Observation of nematode-induced root illness is hampered by the opacity of soil along with other increasing media and by the want for adequate replication to enable statistically meaningful but destructive sampling. Observation of symptom improvement on roots in an X-ray-transparent medium was explored by means of non-destructive two-dimensional X-ray imaging of cotton and sunflower seedlings. Seedlings were grown in germination pouches and root systems had been inoculated with freshly hatched M. incognita juveniles just after initial lateral root emergence (3-4 days following germination). Soon after gall initiation, infected seedlings had been taken to the development and X-ray facility at Phenotype Screening and transplanted into an X-ray-transparent substrate consisting of 0.5-1-mm expanded polystyrene beads.Atodes been studied and described. The moss Hypnum cupressiforme var. cupressiforme was collected in November 2011 at Terrible Salzungen, Thuringia, dried with heat, and ready for the herbarium. Soon thereafter terminal swellings were noted and dissection demonstrated that the swellings contained females, males, and second-stage juveniles. Numerous galls were dissected in water. One female, many males and about 30 of J2 were revived 1 hour following immersion. This species was placed tentatively in Anguina because the female was slightly swollen and heat-relaxed inside a close to circular pattern (length 1.2 mm), but they are not definitive Anguina characters along with the taxon also could match in Subanguina. Internally the female was badly degraded plus the reproductive tract could not be studied; nonetheless, the metacorpus in all stages appeared to become substantially extra substantial than that illustrated for other moss-galling Anguinidae. Males were similar to these of Subanguina brenani (=Anguina brenani), described from Oxford, England, around the moss Pottia bryoides, but had been longer (1.1-1.two mm inside the undescribed species, 0.6-0.7 mm in S.
