- Narrow distribution, Asia and Oceania (but not confirmed). On bele (aibika, sliperi kabis, island cabbage, Abelmoschus manihot), cotton, okra, beans, eggplant, peanut.
- Eggs laid on leaves; nymphs green-yellow, like the adults but wingless; both feed on leaves causing crinkling, yellow patches, sometimes white edges.
- Even small numbers cause damage, perhaps injecting toxic saliva when feeding. Worse in dry times.
- Natural enemies: ladybird beetles, parasitoid wasps, spiders.
- Cultural control: test varieties for resistance.
- Chemical control: PDPs: neem, derris, pyrethrum, or chill; spinosad or Bt (Bacillus thuringiensis); or synthetic pyrethroids, but they will kill natural enemies.
