Tissue samples were collected from coconut palms with symptoms of lethal yellowing (LY) disease in Jamaica. Palms were sampled at 50 sites exhibiting varying levels of mortality due to LY. Samples were assayed for phytoplasma infection by polymerase chain reaction (PCR) assays. Detected phytoplasmas were characterized by dot blot nucleic acid hybridisation, restriction fragment length polymorph...

In 2006, Batrachedra nuciferae Hodges (Lepidoptera: Batrachedridae) was the first phytophagous insect to be reported from inflorescences of coconut, Cocos nucifera L. (Arecales: Arecaceae), in Trinidad, West Indies. At that time, it was suggested to be an introduced species contributing to decreasing coconut yields on the island and potentially a threat to other palms. In this preliminary study...

It was shown that intersterno-costoclavicular ossification often appears together with pustulosis palmoplantaris by Sonozaki et al., 1980. We report here a patient of Graves' disease associated with intersterno-costoclavicular ossification and pustulosis palmoplantaris, and discuss the relationship with these conditions.

—Despite efforts by researchers worldwide to assess the biodiversity of plant groups, many locations on Earth remain poorly surveyed, resulting in inadequate or biased knowledge. Robust estimates of inventory completeness could help alleviate the problem. This study aimed to identify areas representing gaps in current knowledge of African palms, with a focus on Benin (West Africa). We assessed ...

For those of you familiar with previous updates, you might recall the title was “New Disease of Queen Palms (Syagrus romanzoffiana) in the South Florida Landscape.” The change in the title reflects additional information obtained since the last update prepared in May 2006. This document is a summary of information regarding this new disease. If you only want to know the “bottom line,” please fa...

The red palm weevil Rhynchophorus ferrugineus Olivier (Curculionidae/Rhynchophoridae/Dryophthoridae) is a lethal pest of young coconut palms, Cocos nucifera L. (Arecales: Arecaceae), with a highly aggregated population distribution pattern. R. ferrugineus is managed in several coconut growing countries using area-wide pheromone based programmes that need a substantial commitment of funds over a...

We present a method to simultaneously reconstruct the shape and motion of an unknown smooth convex object. The object is manipulated by planar palms covered with tactile elements. The shape and dynamics of the object can be expressed as a function of the sensor values and the motion of the palms. We present a brief review of previous results for the planar case. In this paper we show that the 3...

INTRODUCTION Rhodnius neglectus is a triatomine that colonizes different palm species. In this study, we aimed to describe the presence of this triatomine bug in the royal palms (Roystonea oleracea) in a rural region of the State of Goiás. METHODS Palm infestation was investigated by dissecting the palms or by using live-bait traps. RESULTS Two palm trees were infested by R. neglectus negat...
