Pest of Rubber
Termites• form colonies at the base of the trunk. • Some species prefer living trees while others feed on
dead tissues.• Newly-budded plants are very susceptible to termite
attack• Affected young trees show deficiency symptoms. • In large trees, the trunk may be honeycombed with
disintegrating tissues, without any visible signs of injury, that may easily fall when strong winds blow.
• Termites are hard to control when the colonies are fully developed.
• Macrotermes sp. Coptotermes curvignathus
Control Measure
• Practice good sanitation in plantation• Destroy early colonies of termites• Regularly inspect termite tunnels and destroy
them
Leucopholis irrorata
• Root-feeding larvae• Eggs are laid singly or in clusters in the soil. • The larvae lives entirely in the soil. • They are voracious feeders and may consume the
roots of rubber (seedlings stage) and cover crops. • Affected young trees have yellow leaves and dying
shoots, and in severe cases, the trees may die.• Control: Use polybags in raising rubber seedlings to
prevent larvae attack, biocontrol
