The Dutch Plant Protection Service daily receives samples with insect specimens from imported end products like cut flowers and vegetables. A quick and adequate diagnosis of the intercepted specimens is required to hinder trade as little as possible. At the inspection locations dispersed over The Netherlands trained inspectors are allowed to take the decision for release or hold up of any consignment under official control, so-called first-line diagnosis. Depending on the species identity, a consignment will be subsequently released or rejected, the latter after second-line diagnosis of a quarantine or otherwise regulated pest. An additional list of 63 species intercepted in The Netherlands, partly as a result of selective first-line diagnosis, is given. After risk analysis,
Ceratothripoides brunneus, Frankliniella bispinosa
were placed under phytosanitary supervision. At present 219 species have been intercepted, with 54 species not identified to species level.
