Scolytinae species are among the most damaging forest pests, and many of them invasive. Over 1500 interceptions were recorded at New Zealand's borders between 1950 2000. Among 103 Dendroctonus ponderosae, Ips typographus, other high-risk species, but actual arrivals probably included more species. Interceptions primarily associated with dunnage, casewood (crating), sawn timber, originated from 59 countries, mainly Europe, Australasia, northern Asia, North America. Zealand United States interception data highly correlated, 7 10 intercepted shared. Interception frequency establishment in not clearly related. By combining true bark beetles we obtained on found shipments around world. Logistic regression analysis showed that frequently about four times as likely rarely to be established somewhere. records wood borers valuable for prediction invaders our general understanding invasions. The use alternatives solid packaging, such processed wood, should encouraged reduce spread invasive borers.
