The Toxin Cercosporin is a Virulence Factor for Infection of Coffee by Cercospora coffeicola [PDF]
, 2019 ABSTRACTBrown eye spot, caused byCercospora coffeicola, causes significant losses in both quality and quantity of coffee production. As manyCercosporaspp. produce the photoactivated toxin cercosporin, this study aimed to determine the role of cercosporin inC. coffeicolapathogenesis by creating disruption mutants unable to produce the toxin.

Abundance of Coffee berry borer in feral, abandoned and managed coffee on Hawaii Island
Journal of Applied Entomology, Volume 144, Issue 10, Page 920-928, December 2020., 2020 Abstract Coffee berry borer (Hypothenemus hampei Ferrari), the most damaging insect pest of coffee worldwide, was first detected on Hawaii Island in 2010. Poorly managed, abandoned and feral coffee sites on the island have since been thought to harbour coffee berry borer (CBB) populations, which then negatively impact neighbouring coffee farms.
