Responding to incursions of exotic sirex spp.into New Zealand

摘要

Two recent and noteworthy siricid woodwasp incursions are presented as case studies, with an emphasis on the science used as decision support. The first case study describes the advantages of using morphological and molecular diagnostic approaches incombination. This case resulted in the first published host record association between Sirex noctilio and Amylostereum areolatum, on Cedrus atlantica host. The second case study reports the application of published life cycle developmental data (Madden 1981) to assess establishment risk, and profiles the entry of Sirex juvencus into New Zealand within timber stamped with the ISPM 15 Mark, and the Ministry of Agriculture and Forestry Biosecurity New Zealand's (MAFBNZ) actions to mitigate this risk entrypathway. Historical records of siricid woodwasps border detections in New Zealand are examined and discussed, in relation to the patterns of interception over time, and the key species intercepted.
