Distribution and Dispersal of Cactoblastis cactorum (Lepidoptera: Pyralidae), an Exotic Opuntia-Feeding Moth, in Florida

Extended Geographical Distribution and Host Range of the Cactus Moth, Cactoblastis Cactorum (lepidoptera: Pyralidae), in Argentina

Lack 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...

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 ...

Laboratory Performance of CaCtoblastis CaCtorum (LePidoPtera: PyraLidae) on South and north american opuntia SPecieS occurring in argentina

the cactus moth, Cactoblastis cactorum (berg), is native to South america. 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...

ECOLOGY AND POPULATION BIOLOGY Reproduction, Longevity, and Survival of Cactoblastis cactorum (Lepidoptera: Pyralidae)

Screened potted cactus,Opuntia ficus-indica (L.) Mill., plants containing pairs of adult male and female cactus moths, Cactoblastis cactorum (Berg) (Lepidoptera: Pyralidae), were placed in a cactus Þeld in St. Marks, FL, to measure oviposition patterns under ambient conditions. Results showed a narrow window for oviposition during third and sixth day of adult femaleÕs life. Peak oviposition act...
