Control methods in organic citrus against the new invasive Mealybug Delottococcus aberiae

Delottococcus aberiae is a widespread invasive mealybug native to South Africa. It reaches high population levels and causes severe distortion and size reduction in developing fruits. Combining different methodologies, such as precautionary measures, application of plant protection products, an attract-and-kill system with sexual pheromone, physical barriers against ants and the release of predators, may help control mealybug.

Knowledge Networks in Organic Fruit Production across Europe: A Survey Study

Limited data regarding the resources and methods used by organic fruit growers to learn about production practices are available, even though this information is crucial to improving the efficacy of knowledge transfer. Therefore, a survey to gain information from knowledge networks dealing with organic fruit production about their structural organisation, tasks and methods of communication was carried out in twenty-one countries from Europe and the Mediterranean basin.
