Summary
The scale insect Orthezia insignis damages the host plant by feeding on its phloem and excreting nutrients which promote the growth of sooty mold. Biocontrol using the coccinellid predator Hyperaspis pantherina has proven to be successful in controlling the scale insect on Saint Helena (in the South Atlantic Ocean).
Uses
Orthezia insignis may have uses for biocontrol of the invasive shrub lantana (Broughton 2000).
Reproduction
Orthezia insignis is a mobile scale insect, which as an adult female has a large wax ovisac. The species is parthenogenetic. The eggs hatch inside the ovisac and the 1st instar nymphs then move out to feed (Fowler 2005).
Nutrition
Orthezia insignis is highly polyphagous (CBD 2001).
Pathway
Orthezia insignis has been accidentally introduced into many tropical countries on imported plants.

General Impacts
The scale insect Orthezia insignis damages the host plant by feeding on its phloem and excreting nutrients which promote the growth of sooty mold. It may threaten indigenous plants.
Management Info
Biological: Orthezia insignis has a history of successful biological control in Hawaii, and several African countries, through the introduction between 1908 and 1959 of the predatory South American coccinellid beetle, Hyperaspis pantherina (Fowler 2005). Successful biological control and protection of indigenous flora from the scale insect has also been achieved by H. pantherina on the island of Saint Helena in the South Atlantic Ocean; the action was successful in saving a field population of an 'Endangered (ER)' endemic gumwood species (see Commidendrum robustum in IUCN Red List of Threatened Species) from extinction (Fowler 2004; 2005).
For more information on the rearing and transport of H. pantherina for use in biocontrol of O. insignis please see: Fowler, S.V. 2005. The successful control of Orthezia insignis on St. Helena saved natural populations of endemic gumwood trees Commidendrum robustum.

Summary: Abstract: Between 1908 and 1959, the predatory coccinellid, Hyperaspis pantherina Fuersch, was released for the biological control of the ensign scale Orthezia insignis Browne in Hawaii, four African countries and Peru. Substantial control was reported after all the releases, although the outcome was disputed in Malawi. Other coccinellid species and predatory Diptera were released against Orthezia spp. in various programmes from 1952 to 1977. In most cases these agents failed to establish, and there were no reported effects on the target Orthezia spp. In 1993, H. pantherina was released in St Helena for the control of O. insignis on the endemic gumwood tree, Commidendrum robustum (Compositae). Preparatory investigations for this release revealed that the taxonomy and biology of this biocontrol agent were poorly known. Hyperaspis pantherina is redescribed and shown to be the correct name for the species previously known incorrectly as H. jocosa (Mulsant). Hyperaspis laeta Gorham and H. levrati (Mulsant) are transferred to the genus Cyra Mulsant (comb. n.). Hyperaspis metator (Casey) (stat. rev.) is resurrected from synonymy with H. levrati auctt. Studies of the life history revealed that H. pantherina normally lays its eggs directly onto the adult female O. insignis and that the first two instars of the larvae are frequently passed inside the ovisac of the female host, after which the host itself is often consumed. The information on the biology and taxonomy of H. pantherina, together with details of culturing methods, should facilitate the further use of this agent for the classical biological control of O. insignis, a pantropical pest.
