The CottonInfo NymphCheck App is a digital tool to assist with sampling for silverleaf whitefly nymphs by providing image-derived insect counts using a phone camera.
As at late January 2026, NymphCheck is available on app stores as a Beta release.
The software is based on research and development undertaken with support from CRDC by Dr Derek Long and Dr Alison McCarthy from the University of Southern Queensland (UniSQ) Centre for Agricultural Engineering in partnership with Queensland DPI and CottonInfo IPM Technical Lead Dr Paul Grundy.
