First Report of Marginal Scorch Infecting Indigowoad Root in China

During 2015, marginal scorch symptoms were detected in the production base of indigowoad rootin Hubei, China. On the basis of morphological features and 18S rDNA sequences, the pathogen was identified as Cladosporium sp. Koch’s postulates were fulfilled by pathogenicity tests on potted indigowoad root seedlings. To our knowledge, this report is the first of marginal scorch on indigowoad root ca...

Molecular characterization of closteroviruses infecting Cordyline fruticosa L. in Hawaii

In Hawaii, common green ti plants (Cordyline fruticosa L.) have been shown to harbor Cordyline virus 1 (CoV-1) which, along with Little cherry virus 1 (LChV-1), and Grapevine leafroll-associated virus 7 (GLRaV-7), form a distinct clade within the family Closteroviridae. Preliminary work has indicated that, aside from CoV-1, three additional closteroviruses may infect common green ti plants in H...

First report of an endoparasitic epicaridean isopod infecting cephalopods.

This is the first report of an epicaridean isopod infecting cephalopods. Three cryptoniscus larvae (Isopoda, Epicaridea) were recognized externally and found entirely embedded in the oral bulb at the beginning of the esophagus of two female Patagonian squid (Loligo gahi) sampled in North Peruvian and South Chilean waters, respectively. There was an extremely low prevalence (< 2%) and mean inten...

Phytoplasmas are not associated with quick decline of macadamia trees in Hawaii

Association of phytoplasma with quick decline of macadamia trees in Hawaii was reevaluated. Twenty samples were collected from symptomatic and symptomless trees of the two susceptible cultivars cv. 333, and cv. 344 grown at Keaau and Kaiwiki on the island of Hawaii. Ultrasensitive nested-PCR assays using two universal primer pairs failed to detect phytoplasmas in all samples tested, contradicti...
