The economic impacts of Huanglongbing disease have prompted global surveillance of citrus psyllid vectors. While yellow sticky traps (YSTs) are widely used to detect pests such as the African citrus psyllid (Trioza erytreae) and the Asian citrus psyllid (Diaphorina citri), alternative methods may capture unique species and greater taxa richness and abundance, which could impact downstream species identification and diagnostics. The writers assessed psyllid richness and abundance across 4 sites within major citrus-growing regions of eastern Australia, and found that combining hand sampling with YSTs captured more species compared to light trapping and pan traps, but all sampling techniques collected unique taxa.
