Bark Borer Pest Management in Mango: Symptoms, Treatment, Chemical, Biological, Natural, and Organic Control

The Mango Bark Borer, Indarbela tetraonis, and Indarbela quadrinotata, belonging to the Family Metarbelidae of the Order Lepidoptera, are also known as Bark Eating Caterpillars. This pest is native to India. The Mango bark borer’s larvae feed on mango tree bark, creating tunnels that can weaken and even kill the tree. The larvae also feed on the phloem and xylem of the tree, reducing the tree’s ability to transport nutrients and weakening it.

Life Cycle of Mango Bark Borer Pest in Mango Crop

The life cycle of the mango bark borer pest has four stages. They are egg, larva, pupa, and adult. The cycle begins when the female bark borer lays eggs in clusters beneath the loose bark of the trees. The eggs hatch into caterpillar larvae within one to two weeks. The caterpillar is the most damaging stage of this pest, during which they feed on the tree’s inner bark and tunnel through the wood in a zig-zag manner in the April-December months.

These larvae produce silken webs on the wood consisting of their excrement and wooden particles. After several weeks of feeding, the larvae pupate in 3-4 months and transform into a pupa in the boreholes. The pupa hatches into an adult moth. The adult moth lays eggs on the bark of the mango tree, and the cycle repeats itself.
