The new world screwworm: distribution and eradication

Image
The new world screwworm Cochliomyia hominivorax (Coquerel) was eradicated in North America, Libya and other locations using the sterile insect technique (SIT). To examine the role of weather in its eradication, a physiologically-based demographic model (PBDM) was developed and used to characterize its range of year-round persistence. Winter temperature and rainfall are shown to have a strong influence on screwworm outbreaks and in facilitating eradication in North America and Libya. Prospective analysis for the Mediterranean Basin suggests eastern areas are most favorable for screwworm establishment (e.g., the Nile River area of Egypt). The SIT eradication programme and its possible extension into South America are discussed. Expected +2°C climate warming is predicted to increase the potential year-round range of screwworm in the SE USA. Gutierrez A.P., Ponti L., 2014.

Agroecological management of invasive species

Image
During a meeting of the Italian National Academy of Entomology held in Florence on 18 February 2012, Luigi Ponti delivered a public lecture titled "Management of invasive species in the frame of an agro-ecological vision: the case study of Tuta absoluta (Meyrick)". The talk was part of a workshop on T. absoluta where Italian research stakeholders reported on this major invasive pest problem for the Mediterranean Basin. Dr. Ponti's talk focused on how physiologically-based weather-driven demographic models ( CASAS models) integrated into a GIS may aid ecologically-based management of invasive species such as T. absoluta by sorting out the complexity of the global change biology involved. Examples of how invasive species can be assessed in the frame of an agro-ecological vision were provided and prospective applications to T. absoluta outlined along with common misunderstanding about invasive species that may be clarified using the modeling approach of the GlobalChang...

Agriculture, food security and climate change in Europe

Image
The GlobalChangeBiology project is part of the Joint Programming Initiative on Agriculture, Food Security and Climate Change ( FACCE – JPI ) funded by the European Union under the 7th Framework Program. The goal of FACCE – JPI is to achieve, support and promote integration, alignment and joint implementation of national resources under a common research and innovation strategy to address the diverse challenges in agriculture, food security and climate change. Partnering MACSUR , the first pilot action of FACCE – JPI that will start officially in June 2012 (see first newsletter ), the GlobalChangeBiology project will provide case studies on grape and olive systems in the Mediterranean Basin. The MACSUR project is a knowledge hub that brings together 73 research groups from across Europe and will provide a detailed climate change risk assessment for European agriculture and food security, in collaboration with international projects including the GlobalChangeBiology project . As...
