Introduction Mango is considered as king of all fruits. India produces 80% of world's mangoes. About 175 species of insects have been reported damaging mango plant. Pests like Mango Hoppers, Mealy Bug and Stone Borer causes considerable damage during nursery stage of mango.

Mango Hoppers Nature of Damage: Mango Hopper nymphs and adults suck cell sap from the tender shoots during rainy session. Infested leaves of Mango shrivel, turn brown & ultimately fall down. Mango Hoppers secrete honeydew like substance which encourage the growth of black sooty mold which severely affects photosynthetic activity of leaves. Mango hoppers are known to affect the marketable quality of seedlings in the nursery. Shoot Damage by Mango Leafhopper Honeydew Secretion by Mango Leafhopper

Mango Hoppers Control Spray 0.05% Malathion 50 EC or 0.04% Phosphamidon 85 EC in Oct- Nov. Fogging with Mixture of Malathion and Diesel in 1.5 : 8.5 proportion. At higher level of hopper density (>4 hopper/ shoot), spray 0.005% Imidacloprid, while at lower density (<4 hopper/shoot), spray 3000 ppm Azadirachtin @ 2ml/liter. Use of natural enemies of hoppers like Reduviid and Irantha armiper. White fungus, Verticillum lacanii is also an effective control. Mango Leafhopper

Mango Mealy Bug: Drosicha maniferae Host Plants: Mango, Jackfruit, Guava, Papaya and Lemon. Nature of Damage : Nymphs sucks sap from tender shoots and leaves which dry and drop. Mango Mealy Bug Control Soil solarization and deep plough during summer to expose eggs. Application of 5 cm wide sticky bands around stem in mid December prevents nymphs from crawling up the seedling. Spray 2.5 ml Methyl Parathion in 10 liters of water.

Mango Stone Borer Stemochetus mangiferae Nature of Damage : Mango Stone Borer attacks soft fleshy varieties of mango. Stone borer grub on hatching, create tunnel in a zigzag manner through the pulp, endocarp and seed coat and reaches the cotyledons and destroys them. Stone borer adult also feeds on the developing seeds and it may hasten the maturity of infested fruits. Stone borer in Mango destroy the germination viability of seed/ stone in Mango nursery. Adult of Mango Stone Borer

Mango Stone Borer Stemochetus mangiferae Control Collect and destroy fallen fruits and keep the mother plant block clean. Raking soil around tree in October-November and March is helpful. Spraying 0.05% Diazinon on trunk of mango tree and primary branches in October-November. Infected Fruit by Mango Stone Borer Grub of Mango Stone Borer
