Mango (Mangifera indica Linnaeus) is known as king of fruits in India and is considered as one of the most delicious, exotic, nutritious and attractive fruit. This fruit is recognized as a good source of β-carotene, vitamin A, vitamin B complex, vitamin C, nutritive minerals, digestive sugars and trace elements. However, insect pest problem is one of the major limiting factors in mango production. In the above perspective, this book comprehends the growth, development, reproduction and spatial distribution pattern of different life stages to generate basic data helpful in understanding the population dynamics and management of mango fruit flies (Bactrocera spp., Diptera:Tephritidae).
