Addressing the threat of Cactoblastis cactorum (Lepidoptera: Pyralidae), to Opuntia in Mexico

Abstract

The South American cactus-feeding moth, Cactoblastis cactorum (Berg) (Lepidoptera: Pyralidae), is a serious threat to the high diversity of native Opuntia species in Mexico, both wild growing and cultivated. An action plan has been compiled and submitted to the FAO for funding. The objectives are to collate all available information on the insect, to evaluate the risks to Mexico, to verify the presence of the insect and the most likely route of entry; also to mobilize the cactus pear industry, cactus and related societies, and government officials into the action plan, to embark on an extensive publicity campaign, and to consult international experts, including those in neighboring countries. The final goal is to generate a strategy that will be followed by the Mexican government with a medium- to long-term plan to ensure the protection of the cactus pear industry and the native cactus flora.
