Aulacaspis yasumatsui Takagi The Cycad Aulacaspis Scale (CAS), Aulacaspis yasumatsui, a native of Southeast Asia, is found on plants from the gymnosperm order Cycadales. Its preferred host belong to the genus Cycas. CAS is highly damaging to cycads, which include horticulturally important and endangered plant species. The scale has the potential to spread to new areas via plant movement in the horticulture trade. Its known introduced range includes some states in the USA including Florida and Hawai‘i, Cayman Is. Puerto Rico and Vieques Islands, US Virgin Islands, Singapore, Hong Kong, Taiwan, and Guam. CAS has been reported from the island of Rota (Northern Mariana Islands) in 2007 and Palau in 2008. or at the base of the petiole.

Report and Recommendations on Cycad Aulacaspis Scale, Aulacaspis Yasumatsui Takagi (Hemiptera: Diaspididae)
IUCN/SSC Cycad Specialist Group – Subgroup on Invasive Pests Report and Recommendations on Cycad Aulacaspis Scale, Aulacaspis yasumatsui Takagi (Hemiptera: Diaspididae) 18 September 2005 Subgroup Members (Affiliated Institution & Location) • William Tang, Subgroup Leader (USDA-APHIS-PPQ, Miami, FL, USA) • Dr. John Donaldson, CSG Chair (South African National Biodiversity Institute & Kirstenbosch National Botanical Garden, Cape Town, South Africa) • Jody Haynes (Montgomery Botanical Center, Miami, FL, USA)1 • Dr. Irene Terry (Department of Biology, University of Utah, Salt Lake City, UT, USA) Consultants • Dr. Anne Brooke (Guam National Wildlife Refuge, Dededo, Guam) • Michael Davenport (Fairchild Tropical Botanic Garden, Miami, FL, USA) • Dr. Thomas Marler (College of Natural & Applied Sciences - AES, University of Guam, Mangilao, Guam) • Christine Wiese (Montgomery Botanical Center, Miami, FL, USA) Introduction The IUCN/SSC Cycad Specialist Group – Subgroup on Invasive Pests was formed in June 2005 to address the emerging threat to wild cycad populations from the artificial spread of insect pests and pathogens of cycads. Recently, an aggressive pest on cycads, the cycad aulacaspis scale (CAS)— Aulacaspis yasumatsui Takagi (Hemiptera: Diaspididae)—has spread through human activity and commerce to the point where two species of cycads face imminent extinction in the wild. Given its mission of cycad conservation, we believe the CSG should clearly focus its attention on mitigating the impact of CAS on wild cycad populations and cultivated cycad collections of conservation importance (e.g., Montgomery Botanical Center). The control of CAS in home gardens, commercial nurseries, and city landscapes is outside the scope of this report and is a topic covered in various online resources (see www.montgomerybotanical.org/Pages/CASlinks.htm).

Risks from Unknown Quarantine Organisms Posed by The
Recommendation of a Pathway Approach for Regulation of Plants for Planting A Concept Paper from the IUFRO Unit on Alien Invasive Species and International Trade* Issue: A Pathway Approach Is Needed Many forest pests have been introduced into new locations on plants for planting. Mounting scientific evidence suggests that the current pest-by-pest regulatory approach and reliance on inspection to detect pests is untenable in today’s global marketplace. Much recent experience demonstrates the need to curtail the introduction of plant pests that are present in an exporting territory but not yet known to science. Therefore, the forest entomology and pathology science community recommends a pathway approach to regulating nursery stock, similar to that adopted for wood packaging material (WPM). Best management practices effective at preventing known pests will significantly reduce the risk of introducing unknown pests as well. Introduction and Scope There are three problems with the current phytosanitary regulatory approach: 1) It relies on inspection, but the volume of world trade has expanded far beyond inspection capacity. 2) It focuses on addressing the risks associated with known quarantine organisms, but most pests introduced on plants for planting are previously unknown or unpredictably aggressive pests. 3) Article VI.2 of the IPPC prohibits requiring phytosanitary measures against unregulated pests. The limitations of current measures were accepted long ago to prevent the misuse of phytosanitary concerns as artificial barriers to trade. In the ensuing years, however, it has become evident that WPM and plants for planting routinely provide pathways for unanticipated pests. With the adoption of ISPM-15 (FAO, 2002), the exchange of known and unknown pests via WPM has been significantly reduced.

Hawaii 96822 and Plant Production and Protection Division. Food and Agriculture Organization. Rome. Italy The armored scales (Family Diaspididae) constitute one of the most successful groups of plant-parasitic arthropods and include some of the most damaging and refractory pests of perennial crops and ornamentals. The Diaspididae is the largest and most specialized of the dozen or so currently recognized families which compose the superfamily Coccoidea. A recent world catalog (19) lists 338 valid genera and approximately 1700 species of armored scales. Although the diaspidids have been more intensively studied than any other group of coccids, probably no more than half of the existing forms have been recognized and named. Armored scales occur virtually everywhere perennial vascular plants are found, although a few of the most isolated oceanic islands (e.g. the Hawaiian group) apparently have no endemic representatives and are populated entirely by recent adventives. In general. the greatest numbers and diversity of genera and species occur in the tropics. subtropics. and warmer portions of the temperate zones.
