Studies of the Coccoidea. 14. The genera Aspidiotus, Diaspidiotus and Hemiberlesia in Queensland

Abstract

In Queensland the genus Aspidiotus is represented by three species and Diaspidiotus and Hemiberlesia are each represented by two species. A. hederae (Vall.), H. lataniae (Sign.) and H. rapax (Comst.) are extremely widely distributed on a great variety of hosts. A. queenslandicus Brimb. and D. loranthi (Laing) are native species. None of the species in these three genera is of major direct concern to economic crops. H. lataniae, however, has in recent years become of some economic importance by the appearance of odd individuals on avocado fruit consigned to certain interstate markets.
