“…In coconut, testing of resistance is usually performed by planting different varieties in a LYD endemic area (Baudouin et al, 2009; Odewale and Okoye, 2013). In PNG, the area in which BCS is expanding is home to the nation's coconut germplasm collection, forcing authorities to move representative germplasm to a safer (remote) site.…”

Coconut Lethal Yellowing Diseases: A Phytoplasma Threat to Palms of Global Economic and Social Significance

The recent discovery of Bogia coconut syndrome in Papua New Guinea (PNG) is the first report of a lethal yellowing disease (LYD) in Oceania. Numerous outbreaks of LYDs of coconut have been recorded in the Caribbean and Africa since the late Nineteenth century and have caused the death of millions of palms across several continents during the Twentieth century. Despite the severity of economic losses, it was only in the 1970s that the causes of LYDs were identified as phytoplasmas, a group of insect-transmitted bacteria associated with diseases in many other economically important crop species. Since the development of polymerase chain reaction (PCR) technology, knowledge of LYDs epidemiology, ecology and vectors has grown rapidly. There is no economically viable treatment for LYDs and vector-based management is hampered by the fact that vectors have been positively identified in very few cases despite many attempted transmission trials. Some varieties and hybrids of coconut palm are known to be less susceptible to LYD but none are completely resistant. Optimal and current management of LYD is through strict quarantine, prompt detection and destruction of symptomatic palms, and replanting with less susceptible varieties or crop species. Advances in technology such as loop mediated isothermal amplification (LAMP) for detection and tracking of phytoplasma DNA in plants and insects, remote sensing for identifying symptomatic palms, and the advent of clustered regularly interspaced short palindromic repeats (CRISPR)-based tools for gene editing and plant breeding are likely to allow rapid progress in taxonomy as well as understanding and managing LYD phytoplasma pathosystems.

“…The LYD was detected in a ten hectare coconut plantation in 1995 when a general disease survey was conducted. By the eleventh year (2006), 98.8% of the West African tall (WAT) palms in the same field had died, while averages of 72% of the dwarfs were lost [4].…”

This work was carried out in collaboration between all authors. Author EIE designed the study, performed the statistical analysis, wrote the protocol and the draft of the manuscript. Authors IBO, NOA and CEA managed the collection of LYD samples from different locations.Author CIA managed collection of insects and identification. Author CEI managed weed species identification. Author EAOD performed study on associated LYD pathogens. Authors JOO and CDA managed the identification of coconut varieties. Author IJO helped in the location and identification of LYD coconut palms. All authors read and approved the final manuscript.
