Import notes:

Cameron et al. (1989) - between August 1927 and February 1928, natural enemies of Pseudococcus calceolariae were collected in Australia for the Citrus Experimental Station in California, USA. In February 1928, en route back to the USA, individuals of some of the species collected, including Pullus sp., were left in New Zealand. They were taken to the Cawthron Institute in Nelson, but were not released. In December 1928, a consignment of Pullus sp. was sent to the Cawthorn Institute from California, USA, originating from the material collected in Australia between August 1927 and February 1928. There were no releases from this consignment and by October 1929 all had died.
