A molecular method for biomonitoring of an exotic plant-pest: leafmining for environmental DNA
<p><span>1. Understanding how invasive species respond to novel environments is limited by a lack of sensitivity and throughput in conventional biomonitoring methods.<i> </i>Arthropods in particular are often difficult to monitor due to their small size, rapid lifecycles, and/or visual similarities with co-occurring species<i>. </i>This is true for the agromyzid leafminer fly, <i>Liriomyza sativae</i>, a global pest of vegetable and nursery industries that has recently established in Australia. </span></p> <p><span>2. A robust method based on environmental DNA (eDNA) was developed exploiting traces of DNA left inside 'empty' leaf mines, which are straightforward to collect and persist longer in the environment than the fly. This extends the window of possible diagnosis to at least 28 days after a leaf mine becomes empty. The test allowed for visually indistinguishable leafmining damage caused by <i>L. sativae</i> to be genetically differentiated from that of other flies. </span></p> <p><span> 3. Field application resulted in the identification of new local plant hosts for <i>L. sativae</i>, including widely distributed weeds and common garden crops, which has important implications for the pest's ability to spread. Moreover, the test confirmed the presence of a previously unknown population of <i>L. sativae</i> on an island in the Torres Strait. </span></p> <p>4. The developed eDNA method is likely to become an important tool for <i>L. sativae</i> and other leafmining species of biosecurity significance, which, historically, have been difficult to detect, diagnose and monitor. More generally, eDNA is emerging as a highly sensitive and labour-efficient surveillance tool for difficult to survey species to improve outcomes for agricultural industries, global health, and the environment.</p>
