Hidden viruses in traded insects may quietly harm wild pollinator colonies
Bojko J, Abd-Alla A
Pollinators
Bees, beetles, and other insects pollinating your garden or producing your honey may carry hidden viruses that weaken colonies without any visible warning signs, and regulators are only beginning to catch up.
Insects and other invertebrates can carry viruses that don't always make them look sick but still affect how healthy they are and how well they reproduce. Scientists can now detect these hidden infections using modern gene-sequencing tools that are fast and affordable. The tricky part is figuring out what these viruses actually do to the insects, and whether trading or moving insects across borders could spread them to wild populations or other species.
Key Findings
Modern genome-sequencing technologies enable rapid, low-cost detection of invertebrate viruses even at very low infection levels in both wild and mass-reared populations.
Covert (symptom-free) viral infections in mass-reared invertebrate colonies raise unresolved questions about impacts on colony performance, sanitation, and animal health.
The special issue links viral sequence diversity and detection directly to food, feed safety, and international trade policy for invertebrate products.
chevron_right Technical Summary
Advances in DNA sequencing now let researchers detect viruses in insects and other invertebrates quickly and cheaply, even when infections show no obvious symptoms. This matters because insects used in farming, pollination, and food production may carry hidden viruses that affect their health or spread to plants and animals.
