INTRODUCTION

Scope

This standard provides guidelines for assessing the quarantine risks posed by scale insects of potential economic importance and the risk management measures that may be applied.

The scope of this standard is restricted to scale insects affecting fresh fruit and vegetables for human consumption moving in international trade, and excludes plants and plant products intended for propagation or processing.

Outline of requirements

Guidelines for a PRA on scale insects associated with fresh fruits and vegetable in international trade for human consumption include the consideration of aspects of initiation, assessment of probability of introduction and spread and the assessment of potential economic consequences. Options for risk management include sourcing the commodities from pest free areas, in-field management of the insects, areas of low pest prevalence, pre-export or on arrival phytosanitary inspection and possible remedial action, and disinfestation.

This standard is complementary to ISPM No. 11, Pest Risk Analysis for Quarantine Pests Including Analysis of Environmental Risks and Living Modified Organisms, and other relevant standards.
