Using the DAS-ELISA Test to Establish an Effective Distance Between Bait Stations for Control of Linepithema humile (Hymenoptera: Formicidae) in Natural Areas.

Linepithema humile (Mayr), the Argentine ant, is an invasive pest that has spread throughout the United States and is a problem in natural and managed habitats in South Carolina. Foraging patterns and the effectiveness of liquid baits for control of this pest have been studied in urban areas. However, similar studies have not been conducted in natural areas such as parks, picnic grounds, or campsites.

Cassava Ivorian bacilliform virus is a member of the genus Anulavirus.

The complete genomic sequence of Cassava Ivorian bacilliform virus (CIBV) is described. The virus has a genomic organization similar to that of pelargonium zonate spot virus (PZSV), the type member of the genus Anulavirus, but it is most closely related to a second, recently described, anulavirus, Amazon lily mild mottle virus (ALiMMV).

The molecular biology of ilarviruses.

Ilarviruses were among the first 16 groups of plant viruses approved by ICTV. Like Alfalfa mosaic virus (AMV), bromoviruses, and cucumoviruses they are isometric viruses and possess a single-stranded, tripartite RNA genome. However, unlike these other three groups, ilarviruses were recognized as being recalcitrant subjects for research (their ready lability is reflected in the sigla used to create the group name) and were renowned as unpromising subjects for the production of antisera.

Partial nucleotide sequences of the RNA 1 and RNA 2 of lilac ring mottle virus confirm that this virus should be considered a member of subgroup 2 of the genus Ilarvirus.

Partial sequences of the RNA 1 and RNA 2 of LRMV are described. These confirm that LRMV is most closely related to members of the subgroup 2 ilarviruses. However, these sequences also show that LRMV is sufficiently different from other members of subgroup 2 so as to explain why oligonucleotide primers that had been used to amplify related subgroup 2 viruses did not amplify corresponding products from LRMV.

Complete sequence of the genome of two dsRNA viruses from Discula destructiva.

Complete nucleotide sequences were determined for the four dsRNA segments present in isolate 247 of Discula destructiva from South Carolina. The largest dsRNA (dsRNA 1) was 1787 bp in length with a single open reading frame (ORF) that coded for a putative RNA-dependent RNA polymerase (RdRp). The dsRNA 2 was 1585 bp in length with a single ORF that coded for a putative viral coat protein.

Nucleotide sequences of segments 1, 3 and 4 of the genome of Bombyx mori cypovirus 1 encoding putative capsid proteins VP1, VP3 and VP4, respectively.

The complete nucleotide sequences of genomic segments S1, S3 and S4 from Bombyx mori cypovirus 1 (BmCPV-1) have been determined. The segments consisted of 4190, 3846 and 3262 nucleotides encoding putative proteins of 1333, 1239 and 1058 amino acids with molecular masses of approximately 148, 140 and 120 kDa (p148, p140 and p120, respectively). All segments possess a single open reading frame.
