Slipperi Kabis Jassids
What are they?
They are also called leafhoppers or Jassids. They
are small, leaf-feeding insects with needle-like
mouthparts that suck the juices from leaves and stems. There are many species: here we
describe the Okra leafhopper on sliperi kabi. The scientific name is Amrasca.
What damage do they do?
Eggs are laid in the leaves and leaf stalks. The young, called nymphs, are similar to adults
except in size, and they are without wings. The adults are light green, but difficult to see
(photo, right - arrows); they are small, about 1-2 mm long, similar in colour to the leaf. The
leaves turn yellow in patches (photo, left), dry up and die early.
How do I identify them?
Look at the leaves to see light yellow to white patches. Look at the underside of the leaf and
try and find the jassids. There are not many present on each leaf. The leaves may be more
crinkled than normal, but many healthy varieties of sliperi kabis have crinkled leaves.
How do I manage jassids?
Lady beetles, lacewings, spiders and other predators attack both adults and nymphs.
Resistant varieties:
One variety appears resistant. See Kastom Gaden Association for samples to test.
Cultural control:
• Plant new gardens as far away as possible from those with jassids.
Chemical control:
• In Papua New Guinea, derris is used to spray the leaves; a variety from PNG is being
multiplied in Solomon Islands. Contact MAL and KGA for plants to test.
• If insecticides are necessary, use synthetic pyrethroids (for example, lambda cyhalothrin).
