Resumen:
Cactoblastis cactorum (Berg) (Lepidoptera:Pyralidae) is native to South America andhas been used successfully as a biocontrol agentagainst invasive species of Opuntia (Cactaceae). Afterits release in the Caribbean, it entered North America,dispersed to southeastern USA, and may reach Mexicothreatening native cacti biodiversity and industrybased on Opuntia spp. Identifying mortality factorsacting on insect populations is central to develop pestmanagement programs. The objective of this studywas to estimate mortality causes of C. cactorum in itsnative range through life table experiments conductedon the exotic O. ficus-indica (L.) Miller and the nativespecies O. quimilo K. Schum. and O. megapotamicaArechav., to detect vulnerable stages and naturalenemies. The main mortality factors were generalistpredators and native plant defenses. Apanteles opuntiarumMartı´nez & Berta (Hymenoptera: Braconidae)was found to be the parasitoid with the highestpotential as a biocontrol agent.
