Ceroplastes sinensis Del Guercio (Chinese wax scale) is an adventive species recorded on 14 native plant species from 11 genera in 12 families (including one fern sp.) ( Hodgson & Henderson 2000, Morrison 2007, Martin 1999, Plant and Food 2010, Anon. 2009). It also feeds on cultivated/exotic species such as weeping bottlebrush ( Callistemon viminalis ), Citrus sp., flowering gum tree ( Corymbia ficifolia ), Myoporum insulare, Nematolepis squamea, and pomegranate ( Punica granatum ) ( Bain 2008, Hodgson & Henderson 2000, Hedley-Stevens 2009, Plant and Food 2010, Philip 2008, Anon 2009). Young scales were recorded on K. salicornioides while adults were seen on the mistletoe host Leptospermum scoparium in the present study. These are new host records for this scale.

Previous host records for soft brown scale include 24 native species from 16 families and 18 genera (including two fern species: Blechnum fraseri and Histiopteris incisa ) ( Hodgson & Henderson 2000, Walker 2008, de Lange 1997, Martin 1999, Plant and Food 2010). Cultivated/introduced hosts recorded include Abutilon , Dendrobium , blackcurrant ( Ribes nigrum ), alfalfa ( Medicago sativa ), Citrus sp., radiata pine ( Pinus radiata ), apricot ( Prunus armeniaca ), wild cherry ( Prunus avium ), cherry laurel ( Prunus laurocerasus ), nectarine ( Prunus persica var. nucipersica ) and grape ( Vitis vinifera ) ( Hodgson & Henderson 2000, Plant and Food 2010).

Kalasiris perforata (Maskell) (fringed scale). This is the only native coccid recorded on a Korthalsella sp. so far. Previous hosts recorded for this scale comprise of 16 native spp. from 10 genera in 10 families ( Hodgson & Henderson 2000, Plant and Food 2010). In the present study it was recorded on K. lindsayi , which is a new host record for this coccid.

Saissetia coffeae (Walker) (hemispherical scale). Hosts recorded for this adventive species in New Zealand include 20 native species from 16 genera in 15 families (including 6 fern species) ( Hodgson & Henderson 2000, Plant and Food 2010). Cultivated/exotic species infested include boxwood ( Buxus sempervirens ), Citrus sp., quince ( Cydonia oblonga ), Japanese aralia ( Fatsia japonica ), nectarine ( Prunus persica var. nucipersica ), grape ( Vitis vinifera ), Meryta coriacea , umbrella tree ( Schefflera actinophylla ) and tree germander ( Teucrium fruticans ) ( Bain 2008, Hodgson & Henderson 2000, Plant and Food 2010, Anon 2009, Philip 2008). In the present study this scale was recorded on K. salicornioides . This is a new host record for this scale.

Material examined: NEW ZEALAND, CL, Gemstone Bay, on K. salicornioides , 11 April 2010, A. Sultan.

Saissetia oleae (Olivier) (black scale, olive scale, ‘H’ scale) is an adventive species. Previous host records for this species include 19 native plants from 15 families and 18 genera ( Hodgson & Henderson 2000). Cultivated/exotic hosts recorded for black scale include kiwifruit ( Actinidia deliciosa ), pear ( Pyrus communis ), Citrus sp., grape ( Vitis vinifera ), Mexican orange blossom ( Choisya ternata ), Abutilon , Hibiscus sp. and pyramid tree ( Lagunaria patersonia ) ( Hodgson & Henderson 2000).
