Taro egg-sucking bug (399)
Pacific Pests, Pathogens and Weeds
- Narrow distribution. Southeast Asia, Oceania. Present in most Pacific island countries. Many introductions. Preys on eggs of Tarophagus species, the taro planthopper.
- Nymphs and adults suck the eggs of Tarophagus. Adult with black antennae, head, pronotum (the area behind the head); wings and legs are orange. Nymphs similar but without wings.
- Eggs are laid into the leaf or into the collapsed eggs of the planthopper. Spread on the wing and in planting material.
- Effective control reported from some countries, but often in dry times there are high populations of both bug and planthopper. Not sufficient for control of viruses diseases.
- Biosecurity: need to assess risk before introduction even though it is probably specific to Tarophagus.
- Avoid use of organophosphates, carbamates and synthetic pyrethroids if Cyrtorhinus present, or leave at least 4 weeks between their use and release of bug.
