Icerya purchasi Bacteria Beauveria bassiana Biological control ABSTRACT Cottony cushion scale Icerya purchasi Maskell, 1878 (Hemiptera: Margarodidae) is an important pest that inhibits the plant growth and development by sap sucking of the plants, and causes sooty mold in more than 200 plant species, especially in citrus plantation. It was accidentally introduced to California in about 1868 and devastated the citrus industry there until a natural enemy from Australia was introduced in 1888. In: Van Driesche, R.G.

She oversaw the first biological control program in the Galapagos Islands against the cottony cushion scale, Icerya purchasi. The importation 70 years ago of the vedalia beetle, Rodolia cardinalis, for the control of Icerya purchasi in Israel, established an equilibrium of the scale below the economic level for most susceptible vegetations. The devastation on citrus in California (see under Natural Enemies) and, later, in other countries when the scale was accidently introduced, shows how important this scale can be when not under biological control.

Riley, later head of the USDA's Division of Entomology, resulted in swift reductions of I. purchasi populations, saving the burgeoning Californian citrus industry from this destructive pest. It relies on predation, parasitism, herbivory, or other natural mechanisms, but typically also involves an active human management role.It can be an important component of integrated pest management (IPM) programs. The exception being the use of insecticides against ants (see under Chemical Control). Biol. The cottony cushion scale (Icerya purchasi Maskell) program in California over the period 1877- 1879 was the first scientifically and institutionally backed biological control program. Importations of the vedalia ladybird (Rodolia cardinalis) in 1888-1889 by C. V.

Biol. Icerya purchasi is important as one of the first major successes of biological control. In January 2002, the first biological control program was implemented on the Galapagos Islands with the release of the Australian coccinellid Rodolia cardinalis Mulsant to control the invasive cottony cushion scale, Icerya purchasi Maskell. Colonization trials were conducted with the cryptochetid Cryptochetum iceryae and the coccinellid Rodolia iceryae, reared on the margarodids Icerya purchasi and I. aegyptiaca infesting different plant species.

Control History in Galapagos: A multi-agency review concluded that biological control was the only feasible option to manage this species. Importations of the vedalia ladybird (Rodolia cardinalis) in 1888-1889 by C. V. Riley, later head of the USDA's Division of Entomology, resulted in swift reductions of I. purchasi populations, saving the burgeoning Californian citrus industry from this destructive pest. It relies on predation, parasitism, herbivory, or other natural mechanisms, but typically also involves an active human management role.It can be an important component of integrated pest management (IPM) programs.
