Targeting Surveillance for Invasive Agricultural Pests and Diseases

Table of Contents Below.
As a mathematical statistician Gericke Cook is involved in informing invasive species surveillance efforts by the USDA APHIS. She describes how surveillance systems are designed and the various drivers that may impinge on the process. She describes the importance of developing risk maps and illustrates the process using the European gypsy moth as an example. Initial field trials of gene drive mosquitos could likely benefit from the broad and deep experiences of invasive species managers when considering how the design of surveillance schemes intended to detect unwanted movement of the investigational organisms beyond the designated trial site.
