Cactoblastis – biocontrol
Prickly pears Opuntiathemselves introduced around the turn of the nineteenth century, had afflicted millions of hectares in Queensland and New South Wales, Australia, replacing other plant forms. We find that, generally, this is unnecessary because the moths are periodically moving through the pear areas and will lay their eggs on new plants if they find them.
The effort was highly successful.
Means of Movement and Dispersal Top of page Introduction pathways to new locations Biological control: In Australia, mating takes place cactoblaastis the early morning hours and copulation has never been documented at night, or after hrs. Cactoblastis cactorum Hight, S. Biology and Ecology Top of page Nutrition On hatching, all larvae from one eggstick enter the plant at one point.
Introduction pathways to new locations Biological control: Many factors can lead to a mismatch between female egg-laying preferences and offspring performance; however, in this case the new association of Cactoblastis cactorum with North American Opunia plants is likely a cause. Datasheet Cactoblastis cactorum cactus moth. Egg parasitoids attacking Cactoblastis cactorum Lepidoptera: Global Invasive Species Database. Pyralidae in north Florida. Females show clear egg-laying preferences, selecting Opuntia engelmannii varieties linguiformis and engelmannii over other opuntiods Jezorek et al.
Florida Entomologist 84 4: Proceedings of the National Museum Smithsonian Cxctorum Following introduction, Cactoblastis exerted an immediate effect on the agricultural community in South Africa, where it diminished the population of the spineless Opuntia species valued as ” cattle fodder “.
Management As ofa management plan has not been established. Each female can deposit several eggsticks; but can frequently lay Also, if the parasitoids did become abundant, it is possible they might spread back to the Caribbean, lessening the abundance of C. Pyralidae and the native cactus-feeding moth, Melitara prodenialis Walker Lepidoptera: The job involved pasting the eggsticks to small piece of paper and pinning the paper to the new plant.
This natural enemy is effective in controlling small plants. Vigueras and Portillo, ; Mellink and Rojas-Lopez, While consuming the cactus from the inside as they mature, eventually hollowing out the pad.
