The mango stone weevil (Sternochetus mangiferae) is an important monophagous pest of mango, infesting the seed (stone) within. Life-cycle is completed in 40 to 50 days during June-July. Adults hibernate until the next fruiting season. There is only one generation in a year.

In recent years, scale insects (Chloropulvinaria polygonata, Aspidiotus destructor and Rastococcus  sp.) become serious pest on mango. The nymphs and adults of pest suck the sap of leaves and other tender parts which result in reduction of vigour of plants. Scale also secrets honeydew which facilitates in development of sooty mould on different plant parts.

The shoot gall psylla (Apsylla cistallata) is very serious pest of mango. Infestation of this pest results in formation of green conical galls in leaf axis. The pest becomes active from the month if August and galls dry after emergence of adults in the month of march.

Stem Borer (Batocera rufomaculata ) is widely distributed in India and attack a number of fruit trees including mango. The grub of this pest feeds inside the stem, making tunnel upward which results in drying of branches and in severe cases death of tree.

Bark eating caterpillar (Indarbela spp.) has a wide host range and found infesting fruit trees, forest tress and ornamental plants.

Fruit Fly are very small insects  that  lay their eggs in various plant tissues. The Tephritidae contains about 1,200 species characterized by wide heads, black or steely green or blue bodies, iridescent greenish eyes, and wings that are usually mottled brown or black.

Discription of Leaf Webber are Inconspicuous brown moth, Eggs are laid in clusters of about ten, on buds and young leaves, Cream-yellow larvae pupates in the webs, etc.

The mango inflorescence midge (Erosomyia indica) is a major pest of  mango. The adult midge are harmless minute flies which are short lived and die within  24 hours of  emergence after copulation and oviposition.

Mango Mealybug (Drosicha mangiferae), is a serious pest on mango. The nymphs damage sap from tender shoots and inflorescence. In case of  severe  infestation, the  inflorescences dry up and the young  fruits  fall easily.

Three species of hoppers Idioscoynio chypeabis, I. nitidulus and Amritodus atkinsoni are the most important and found on panicles, leaves and stems, respectively.  The adult and nymphs of hoppers, suck the sap from tender parts resulting in reduction of vigoure.
