Sliperi Kabis Shoot Borer
What is it?
It is an insect that feeds inside shoots of
sliperi kabis. It also eats cotton, okra and
tomato. The scientific name is Earias.
What damage does it do?
Caterpillars do the damage. Eggs are laid on stems and
buds. Caterpillars enter the buds and tunnel down the
shoots, or they penetrate the young stems directly. Shoot tips and leaves wilt and die.
How do I identify it?
Look at the stems and leaves to see if they are wilting (photo, top right) and dying.
Look closely for small holes in the stems of these shoots. The caterpillars push their
waste out of these holes. Break the stem near a hole to find the caterpillar in its tunnel
(photo, left). The adult is a green-white moth (photo, below right).
How do I manage shoot borer?
Small wasps attack the eggs, caterpillars and pupae. Lacewings and ladybird beetles
eat the eggs. It is important not to kill these natural enemies with insecticides.
Cultural control:
• Cut out the wilting shoots as soon as they are seen;
• If many shoots are attacked, pull out the plants, stop growing cabbage for a few
weeks, and then plant the crop in another garden;
• Grow more sliperi kabis during the wet season: the damage is less;
Chemical control:
• Use plant-derived pesticides, such as pyrethrum or derris, as they are natural
insecticides and do not last long in the environment. See MAL extension staff.
• Or use insecticides made from bacteria, for example:
o Spinosad, also known as Success; or Bt - Bacillus thuringiensis kurstaki.
