Symptoms: Appearance of small holes with dark pale brown ring encircling it.

Fruit borer (D. albizonalis) or red banded caterpillar infestation has become very serious in major mango growing areas of the West Bengal, east coast of Andhra Pradesh and Orissa causing 10-52% damage of fruits from pin headed stage to full maturity.

Apart from D. albizonalis, another new lepidopteran larval borer (Citripestis eutraphera) has been recorded damaging mango fruits in Karnataka and Tamil Nadu. The larvae have been found boring and feeding on immature mango fruits causing extensive fruit damage.  The infested fruits have bored holes with frass and the fruit often blackened around the bored area.  Several infested fruits also exhibited split.  The young larvae were found scraping the fruit skin causing characteristic scab like patch and the later stage larvae found boring in to the fruit.  Even the adjacent fruits also found bored indicating single larva can damage several fruits.
