Mealybug severely affects the crop of Mango.
Mango mealybug (Drosicha mangiferae), is a pest of mango crops in Asia. The nymphs and females suck plant sap from inflorescences, tender leaves, shoots and fruit peduncles.
There is a range of cultural, chemical and non-chemical techniques for minimizing damage to the mango crop, for example the use of physical barriers to stop Drosicha mangiferae nymphs from crawling up the stem of mango trees, by wrapping plastic sheets or sticky bands around the tree stem.
