A Comparative Genomic Assessment of Invasive Potential in the Planthopper Orosanga japonica (Hemiptera: Ricaniidae)
TL;DR
This study read the insect’s genetic material and examined which of its genes are active, then compared them with those of related insects to identify candidate genes potentially linked to finding and feeding on host plants, tolerating plant toxins and environmental stress, and strengthening the insect’s protective outer barrier.
Abstract
Simple Summary The planthopper O. japonica is an insect native to Asia that has invaded Türkiye, where it spreads through the Black Sea region and damages valuable crops such as tea, hazelnut, and kiwifruit by feeding on plant sap; it is now beginning to invade Southern Europe as well. Because it thrives in new environments and chemical control is often limited, scientists need to understand what makes it such a successful invader. In this study, we read the insect’s genetic material and examined which of its genes are active, then compared them with those of related insects. We identified candidate genes potentially linked to finding and feeding on host plants, tolerating plant toxins and environmental stress, and strengthening the insect’s protective outer barrier. These genes may help explain its invasive success and could serve as targets for more precise, environmentally friendly control methods to help protect crops.
