Resumen

Protopulvinaria pyriformis is polyphagous but infestations in Australia are restricted to ornamental Hedera (Ivy) grown as amenity plants. Pyriform scales have a pear shaped body surrounded by a white waxy fringe. They feed on the underside of the leaves and secrete a clear, sugary liquid known as honeydew. Damage is caused by pyriform scales feeding on plant sap and impacting the plants’ nutrient uptake. Infestations of pyriform scale on plants can result in reduced vigour, leaf drop and reduction in size and quality of fruit. It can also result in the growth of black sooty mould on leaves which blocks sunlight and minimises energy available to the plant.

Peligro
Protopulvinaria pyriformis has been detected at a limited number of properties in Perth, with all infestations on Hedera (Ivy). Protopulvinaria pyriformis is a particularly economically important pest of the avocado industry and a pest of a number of other horticultural and ornamental plants. These include: Mango, avocado, citrus, banana, guava, passionfruit, pomegranate, papaya, eucalyptus, hibiscus, gardenia, ivy, myrtle, laurels, paperplant and frangipani. Given the spread of Protopulvinaria pyriformis it is considered not technically feasible to eradicate.
