With the accelerated development of global trade,invasive species seriously threaten agriculture,forestry,ecological environment and human health.Genomic study provides novel tools,platforms and big data for elucidating the molecular mechanisms and ecological adaptation of the invasive alien species (IAS),and developing new prevention and control technologies.We reviewed the status of invasive insect genomic study,systematically summarized the important roles of genes,gene families,transposons and repetitive sequences in determining insect invasiveness.We also analyzed the potential of genomic...
