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...
متن کاملEvaluation of Metarhizium anisopliae, Beauveria bassiana and Paecilomyces fumosoroseus as Entomopathogens of the Cactus Moth, Cactoblastis cactorum (Lepidoptera:Pyralidae)
The three fungal pathogens Metarhizium anisopliae (Metchnikoff) Sorokin (Hypocreales: Clavicipitaceae), Paecilomyces fumosoroseus (Wize) Brown & Smith (Deuteromycotina: Hyphomycetes), and Beauveria bassiana (Bals.-Criv.) Vuill. (Hypocreales: Clavicipitaceae) were evaluated as potential biological control agents against the cactus moth, Cactoblastis cactorum (Berg) (Lepidoptera: Pyralidae). The ...

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...
متن کاملPEST MANAGEMENT Developing a Sterile Insect Release Program for Cactoblastis cactorum (Berg) (Lepidoptera: Pyralidae): Effective Overflooding Ratios and Release-Recapture Field Studies
In an effort to continue the development of a sterile insect release program against the invasive cactus moth, Cactoblastis cactorum (Berg), we released partially sterile males alone or in combination with fully sterile females at a 5:1 or 10:1 (treated:fertile) overßooding ratio inside large Þeld cages containing Opuntia stricta Haworth (Haworth) host plants. Insects were allowed to mate and l...
متن کاملField-level validation of a CLIMEX model for Cactoblastis cactorum (Lepidoptera: Pyralidae) using estimated larval growth rates.
Invasive pests, such as the cactus moth, Cactoblastis cactorum (Berg) (Lepidoptera: Pyralidae), have not reached equilibrium distributions and present unique opportunities to validate models by comparing predicted distributions with eventual realized geographic ranges. A CLIMEX model was developed for C. cactorum. Model validation was attempted at the global scale by comparing worldwide distrib...
