摘要：There is no morphological identification key to satisfactorily distinguish between the larvae of Aedes (Stegomyia)species with special consideration to endemic and exotic species in Australia. Difficulty in differentiation betweenexotic Aedes (Stegomyia) albopictus (Skuse) and Aedes (Stegomyia) scutellaris Walker has been described previously.1Aedes (Stegomyia) larvae were collected during an interception from an overseas vessel in Darwin, NorthernTerritory, and link bred. The adults were identified as Ae. albopictus. The larval skins and larvae were used todescribe the variation in hair features of larval segment VII that are used to identify Ae. albopictus. The median hairnumber of hair 1–VII was three, whereas the description in Huang's identification key2states four. The median ofhair 2–VII was one, confirming Huang.2However, the variability was higher than described by Huang2and nearlyhalf of the specimens showed different hair numbers on both sides. Individual specimens are therefore not clearlydistinguished from other members of the Aedes (Stegomyia) scutellaris group. This paper also describes thedetection, elimination and surveillance procedures following the interception. These were successful in preventingthe establishment of exotic Ae. albopictus in the Northern Territory following the interception
