The reason for collecting data by the researchers from the coffee shrubs before installing the nets to exclude birds.

Introduction:

Borers are the beetles that affect the production of coffee berries. The study was done to understand the role of predation of borers by the birds by installing the nets. These nets excluded the interference of birds or predation of borers. It was found out that percentage of berries with borers was enhanced due to exclusion of birds in treatment plots. The given graph depicts the percentage of berries with borers before and after installing the nets to exclude birds.
