Summary
3rd International Bemisia Workshop. Barcelona (Spain), 17-20 March 2003.
The Workshop was an outstanding success, enabling 122 scientists from 23
countries to discuss about research on Bemisia and related problems.
Two keynote speakers summarized the state of art on each of 7 working sessions.
The session on Biology highlighted the lack of knowledge on the biology of the
different biotypes identified so far. The Ecology session covered population dynamics,
sampling and Bemisia-host plant relationship. The Virus-vector relationship and
Epidemiology session covered virus identification and strategies for mitigating virus
epidemiology. The Session on Biological Control had most contributions, and focused on
Eretmocerus sp. as the most promising biological agent but also emphasized the importance
of background predation for Bemisia control. Other non-chemical control methods brought
together results in plant resistance and use of screening and UV-absorbing plastics.
The Chemical control and resistance session focussed on insecticide management to delay
resistance development. The meeting endend with a round table discussion on different
IPM approaches over the world. The 4th workshop is sheduled for 2006, location to be
announced.
The Workshop was sponsored by the Ministerio de Ciencia y Tecnología,
and the Departament d’Universitats, Recerca i Societat de la Informació de la
Generalitat de Catalunya. Thanks are also given to the following companies for their
