Rowan Siu

Rowan Siu is a Biological Sciences graduate with a master’s-level specialization in Entomology. His earlier work involved sorting insect samples from field surveys and preparing short reference guides on bees, wasps and mites.

At CAB Direct, Rowan covers bees and wasps, varroa and other mites, insect communication through pheromones, sound and vibration, and the long-term datasets behind reports of insect decline. His articles explain how insects were sampled or counted, how long the records run and whether a decline in one region reflects a wider trend.

His articles appear under his name and stated role. Insect counts, trend estimates and varroa treatment thresholds are checked against traceable sources before publication, the source and date are given for every number, and any correction is dated and kept visible in the article.
