The Importance of Opuntia in Mexico and Routes of Invasion and Impact of Cactoblastis Cactorum (lepidoptera: Pyralidae)
The appearance of the cactus moth Cactoblastis cactorum in Florida has roused concern over its possible effects on the Opuntia -rich areas of Mexico and the southwestern United States. In this paper we discuss the economic importance of Opuntia in Mexico and propose a method to predict the invasion of the alien species C. cactorum . In Mexico, the products derived from Opuntia are mainly human ...

Since its unintentional arrival to the united States in 1989 and to mexican islands in 2006, it has become a serious threat to the diversity of both wild and cultivated species of opuntia mill. in north america. the native ecological host range of C. cactorum has not been directly ascertained and host acceptance is uncle...
متن کاملLack of Associational Effects between Two Hosts of an Invasive Herbivore: Opuntia Spp. and Cactoblastis Cactorum (lepidoptera: Pyralidae)
Associational susceptibility has been predicted to arise when a target plant’s neighbor is more palatable to an herbivore than the target plant itself, resulting in attraction and spillover of the herbivore onto the target plant. This prediction was tested on two hosts of the invasive pyralid moth Cactoblastis cactorum Berg. A combination of observational surveys and experimental plantings were...
متن کاملCollectively Facilitated Behavior of the Neonate Caterpillars of Cactoblastis cactorum (Lepidoptera: Pyralidae)
The behavioral biology of the first instar larva of Cactoblastis cactorum was studied from the time of eclosion until the colony penetrated and initiated excavation of the host plant. Hatching from an egg stick was asynchronous, requiring 20 h for the entire cohort to eclose at 50%-70% RH and significantly longer at a lower range of RHs. On eclosion, neonates aggregated in an arena at the base ...
متن کاملFlight Phenology of Male Cactoblastis Cactorum (lepidoptera: Pyralidae) at Different Latitudes in the Southeastern United States
Long term trapping studies of the invasive moth Cactoblastis cactorum (Berg) were conducted at various latitudes from Puerto Rico to South Carolina. Three flight periods per year were identified at the 5 temperate sites studied, which covered the majority of the infested range on mainland United States. In general, the 3 flight periods across a latitudinal gradient from south Florida to central...
