Article Synopsis
  • Bay laurel, a significant Mediterranean tree native to Italy, is experiencing severe damage from stem blight and internal necrosis connected to ambrosia beetle infestations in Sicily since 2021.
  • Research identified a new fungal species responsible for these issues and confirmed its pathogenicity through tests on potted bay laurel plants.
  • This finding marks the first report of a new pathogen linked to the invasive ambrosia beetle affecting bay laurel, adding to the understanding of plant diseases in the region.

(Rubiaceae) was described by Chamisso and Schlechtendal in 1829, was the first name published for the Philippines and is currently considered a Philippine endemic. The name remained in a taxonomic limbo for almost two centuries as it was variously accepted, synonymized or considered obscure, probably because the type specimen in the Berlin herbarium was destroyed and no original material has survived or is currently known. A combined analysis of the information on morphology, type locality and ecology contained in the protologue and a review of relevant literature on the study of the name by various authors over the last two centuries finally clarified the identity of .

A new disease of fennel is described from Sicily (southern Italy). Surveys of the disease and sampling were conducted during spring 2017 and 2018 in Adrano and Bronte municipalities (Catania province) where this crop is widely cultivated. Isolations from the margin of symptomatic tissues resulted in fungal colonies with the same morphology.

The genus (Melanconidaceae, Diaporthales) in the strict sense is here re-evaluated regarding phylogenetic structure, taxonomy, distribution and ecology. Using a matrix of sequences from ITS, LSU, , , and , eight species are recognised and their phylogenetic positions are determined. Based on phylogenetic, morphological and geographical differentiation, is subdivided into four subspecies.

Plankton samples obtained from estuarine waters of the Colombian Pacific yielded adults specimens of an undescribed species of a paracalanid copepod of the genus . It most closely resembles two Asian species; (Shen & Lee, 1966) from China and (Ali, Al-Yamani & Prusova, 2007) from the Arabian Gulf. These three species share the absence of spinules on the posterior surfaces of exopod segments of legs 2, 3 and 4.

Between 1815 and 1818, Count Nikolai Romanzoff funded an expedition of the Russian brig . Besides their primary goal to discover the Northeast Passage, their aim was to collect scientific specimens, for which the botanist Adelbert von Chamisso and the entomologist Johann Friedrich von Eschscholtz were commissioned. On the Hawaiian Islands, they collected two unknown endemic species that Chamisso and Diederich Franz Leonhard von Schlechtendal later described as and , both now assigned to the large and complex genus (Rubiaceae, Psychotrieae).

A new canker and decline disease of pistachio () is described from Sicily (Italy). Observations of the disease and sampling of the causal agent started in spring 2010, in the area where this crop is typically cultivated, Bronte and Adrano (Catania province) and later extended to the Agrigento and Caltanissetta provinces. Isolations from the margins of twig, branch and stem cankers of declining plants resulted in fungal colonies with the same morphology.
