Records of insect pests on Christmas Island and the Cocos (Keeling) Islands, Indian Ocean.
A survey for pests of crops on Christmas Island and the Cocos (Keeling) Islands was conducted in May 2000. Fifteen new pest records were obtained from Christmas Island: Aleurocanthus woglumi and Neomaskellia bergii (Aleyrodidae), Pentalonia nigronervosa (Aphididae), Coccus sp. and Saissetia sp. (Coccidae), Lepidosaphes sp. and Lindingaspis sp. (Diaspididae), Dysmicoccus sp. and Nipaecoccus viridis (Pseudococcidae), Amrasca devastans [Amrasca biguttula biguttula] (Cicadellidae), Ophiomyia phaseoli (Agromyzidae), Bactrocera albistrigata, B. arecae and B. umbrosa (Tephritidae) and Cosmopolites sordidus (Curculionidae). Six new records were obtained from the Cocos (Keeling) Islands: Aphis gossypii and Rhopalosiphum maidis (Aphididae), Ceroplastes rubens (Coccidae), ?Icerya sp. (Margarodidae), Ferrisia virgata and Saccharicoccus sacchari (Pseudococcidae) and Cosmopolites sordidus (Curculionidae). Aleurocanthus woglumi, Amrasca devastans, Bactrocera albistrigata and B. arecae also represent new records for Australia although these species are known so far only from Christmas Island. A list of insect pests so far recorded from these islands is also included.
