Citrus Leafminer

• The citrus leafminer is a small, light-colored moth that deposits larvae on the leaves of lime trees. The larvae feed on the leaves, creating shallow tunnels -- also called mines -- that distort the leaves. Young trees may experience a reduction in growth but leafminer infestation is rarely fatal.
  
  

Citrus Red Mite

• The feeding of the citrus red mite on the leaves of a lime tree results in the formation of white lines that crisscross the leaves, eventually causing leaves to drop and twig dieback. The same white lines also appear as the mite feeds on the fruit of the tree. The situation is exacerbated when the lime tree is deprived of water.
  
  

Planting

• Few diseases or pests that attack the lime place the tree in a life-threatening situation. The most serious problem is improper planting. Placing a young tree into a hollowed-out area to allow for easy watering will result in foot rot, and the likely death of the tree before 5 years of age.
