Technical Annual Report 2000/01 215 Pseudococcidae (Mealybugs) There are 25 species recorded from the NT. The most commonly collected species are introduced and widespread polyphagous species. Although comprehensive data is available on the Australian fauna, accurate identification is impossible without well-prepared microscope slides. The only new species record for the NT is ?Crisicoccus sp., although there are numerous new host records among the other species listed. The presence of Pseudococcus affinis needs to be confirmed. The most common pest species encountered during the year were Ferrisia virgata (Cockerell), Maconellicoccus hirsutus (Green), Nipaecoccus viridis (Newstead) and Planococcus citri (Risso). Examined material is as follows: ?Crisicoccus sp. (T61) on Acacia at Berrimah Agricultural Research Centre (New NT). Ferrisia virgata (Cockerell) (T99) on cocoa, Theobroma cacao in the quarantine glasshouse Berrimah Agricultural Research Centre (New host); (T163) on Durantia, Berrimah (New host). Maconellicoccus hirsutus (Green) (T62) on Pongamia pinnata at RAAF Darwin (New host); (T63) on Alpinia purpurata at Elizabeth Valley Farm (New host); (T79) on variegated hibiscus at Darwin city (New host). Near Melanococcus sp. (T85) on Eucalyptus bigalerita at Berrimah Agricultural Research Centre (New host); (T97A) on quinine tree, Petalostgma pubsecens at Holmes Jungle (different from T85 and T109) (New host); (T109) on Eucalyptus sp. at Berrimah Agricultural Research Centre. Nipaecoccus viridis (Newstead) (T41)on Citrus paradisi (Grapefruit) at Katherine Research Station; (T46) on Albizzia lebbeck (Indian Siris) at Katherine Research Station (New host); (T48) on Feronia limonia at Katherine Research Station (New host); (T76) on Philanthus multifolia at Nakara (New host); (T100) on cocoa in quarantine glasshouse at Berrimah Agricultural Research Centre (New host). Planococcus citri (Risso) (T26) on cocoa seedlings, Theobroma cacao in quarantine glasshouse at Berrimah Agricultural Research Centre (New host); (T55) on mango, Mangifera indica at Berrimah Agricultural Research Centre. Planococcus sp. T104 (C1438) on a pineapple, Ananas comosus intercepted in quarantine ex East Timor. Pseudococcus affinis (T20, T21) on roots of palm trees at a nursery, Girraween (New NT). Aleyrodidae (Whiteflies) There are 39 species recorded from the NT. Most are introduced and feed on a variety of plants. Neomaskellia bergii (Signoret) is a new record for Australia, while Aleurolobus marlatti (Quaintance), Siphoninus phillyreae (Haliday) and Tetraleurodes sulcistriatus Martin are new records from the NT. Siphoninus phillyreae is now well established in the Alice Springs area and is particularly abundant on pomegranate, Punica granatum. Several new host records were also discovered. Examined material is as follows: Aleurocanthus near spiniferus (Quaintance) (ET84) First East Timor Survey at Darwin.
