Scale insects

Is this a Minor Pest?
Yes
Minor Pest Description

Infestations of tubers and sometimes foliage cause poor growth. Stored tubers are particularly susceptible to attack and large numbers cause shrivelling.

 

Adult female scales are pinkish-brown, roughly oyster-shaped, conical, with a white patch at the tip of the cone. Younger scales are relatively more white. Crawlers are yellow.

Minor Pest What to do.
  • Inspect yams in storage regularly, and remove those that become infested with the scale.
  • Select tubers that are free of scale insects for planting.
