VIII Trilateral Committee Meeting Invasive Species as a Trilateral Challenge Albuquerque April 29, 2003 Jorge Soberón, Laura Arriaga, Elizabeth Moreno, and Jesús Alarcón The possible expansion of the cactus moth, Cactoblastis cactorum, in the USA and Mexico
Response Actions of the Ministry of Agriculture (SAGARPA) 2003 Contigency Program to Avoid the Introduction of Cactoblastis cactorum Includes 20 Mexican states and the corridors between Tamaulipas and the Peninsula of Yucatán. More productive states and wild plantations. Includes 20 Mexican states and the corridors between Tamaulipas and the Peninsula of Yucatán. More productive states and wild plantations.

Conclusions 1. The cactus moth is a threat not only for the Mexican species of Opuntia, but also for the native species of USA. 2. Preventive actions are needed to be established by the USA government to avoid the dispersion of this invasive species to Central and Western USA. 3. We would like to enhance the Department of Interior, or the USA governmental agencies in charge of addressing the wildlife issues, to promote and coordinate some preventive actions in collaboration with the Mexican agencies to avoid the dispersion of the cactus moth.
