04 - Nataima 31 - Whitefly-Resistant Cassava Variety

April 2003- Cali, Colombia.
A cassava variety resistant to one species of whitefly— the first variety of any food crop with resistance to this pest—will be released this month by the Colombian Corporation for Agriculture Research (CORPOICA, it's Spanish acronym). Named 'Nataima-31', the variety is based on a cross made at CIAT between a clone from Ecuador and another from Brazil. The variety's resistance to the whitefly species Aleurotrachelus socialis Bondar will enable cassava growers in northern South America, where this species is a major pest, to lower pesticide applications. In the tropics a total of 43 whitefly species have been reported, damaging a wide range of food and cash crops through direct feeding or transmission of viruses.

03 - 3rd International Bemisia Workshop

March 17-20/2003- Barcelona.
This meeting is the 3rd in a series initiated in 1994 in Shoresh (Israel), when an organising committee headed by Dr. Dan Gerling hosted the International Bemisia Workshop. In 1998, more than 100 oral contributions and 70 posters were presented in Puerto Rico during the 2nd International Workshop on Bemisia and Geminivirus diseases organised by Dr. Mayer and Dr. Maxwell. Organizers hope that this 3rd International Bemisia Workshop will be an international forum to discuss recent research in fundamental and applied Bemisia studies, and to present concrete suggestions for more successful ways to tackle Bemisia-associated problems taking into account sustainable agricultural practices as well as best available technologies.
