In 2023 and 2024, adult male Bactrocera dorsalis, a major fruit pest, were captured in community gardens and produce markets in Belgium. Genomic tracing via nuclear SNP analysis revealed that three adults originated from Africa and eight from Asia, indicating multiple independent occurrences. Intercepted larvae predominantly had an African origin, and a diagnostic set of nuclear SNPs was developed for origin tracing.
