Plagues of mango

The main pests of mango are:

  • The fruit fly (Ceratitis capitata) is an insect that lays eggs in fruit that spoil them. The affected fruits must be removed to avoid affecting the rest. Prevention is done by placing traps to catch the flies before they lay their eggs.
  • Beetles (Trachysomus sp.) It is a beetle that feeds on dead wood. It cuts the stems around preventing the flow of sap. Then it puts the larvae in the affected branch that eventually becomes rot.
  • Mango scales (Aulacaspis tubercularis) are insects that suck sap from the plant.
  • Cowpea aphid (Aphis craccivora Koch.) The nymphs of these insects will eat the fruit at an early stage.Other pests that affect this plant are aphids, bugs and mites fundamentally. Treatment of the latter is usually done with sulfur while the other three above can be treated with malathion.
