The Working Group on Fruit Flies of the Western Hemisphere has its origins in the 1980s when it was proposed to bring together researchers and technical staff in charge of programs against the Mediterranean fruit fly in Guatemala, Mexico, and the United States. The aim was to analyze and discuss research needs and priorities to deal more effectively with the problems of these programs.  Later, a  similar group was formed to meet the research needs of programs against fruit flies of the genus Anastrepha on the American continent. In 1990, following the agreement to unite these two groups, the working group on Fruit Flies of the Western Hemisphere was established. For more information about TWWH, click here.

Americas Congress on Fruit Flies is an international event that brings together experts from all countries of the Western Hemisphere in American continent, to promote the exchange of knowledge on prevention, eradication, and control of fruit flies among members of scientific and academic communities. It takes place during the 10th Meeting of the Tephritids Workers of Western Hemisphere, TWWH, during the celebration of International Year of Plant Health, 2020.

Due to the global health emergency generated by Covid-19 and thinking about guaranteeing the participation and health of attendees, the virtual modality was chosen and it will be held between November 2 and 6, 2020.

Thanks to flexibility provided by the virtual modality, the capacity for congress has been expanded from 300 to 1500 participants. Congress organizers will invite researchers with national and international experience, sector entities, research centers, and universities, as well as fruit and vegetable production unions looking for the participation of Colombian agricultural technicians attached to research and/or technical assistance units.

In December 2018, the United Nations General Assembly proclaimed 2020 as the International Year of Plant Health (AISV). This year is a unique and unrepeatable opportunity to raise awareness about how plant health protection can eliminate hunger, reduce poverty, protect the environment, and stimulate economic development. International Year of Plant Health Website.
