Barcoding as a tool to track emerging pests: the case of the sugarcane long-horned beetle

Identifying agricultural crop pests quickly and reliably is critical to track their spread and to apply suitable control measures where needed. However, the identification of insect pests is often hampered by the lack of taxonomic expertise, especially in complex and poorly known tropical groups. DNA barcoding is often used as a supporting tool to identify species in the context of invertebrate pest management but relies on comprehensive and well-curated molecular databases.

Addressing uncertainty in impact assessments for alien species

Impact classification schemes for alien taxa are becoming more prominent as the threats posed by biological invasions increase. A recent study found that despite a high variety of uncertainties occurring in impact assessments, some of which cannot be eliminated easily, communicating their existence, cause and variety can lead to more useful and reliable outcomes of impact assessments.

Insights into the future distribution of invasive alien plants in the Heuningnes catchment

A recent study by former C∙I∙B student, Bongolethu Mtengwana, demonstrated the advantage of combining different species distribution models to identify areas that are at risk of future invasions by Invasive Alien Plants (IAPs).

Alien pest of wheat and maize could pose a threat to South Africa

Alien pests of agriculture cause billions of Rands’ worth of damage to South African crops every year. Knowledge on which pests could pose a threat in the future is vital to inform South Africa’s biosecurity.
