Study on morphometric parameters of the blue bug, Chrysocoris purpureus

Abstract

The blue bug, C. purpureus attacked mainly the tender shoots and fruits of Jatropha. It was found sucking the sap from fruits, due to which the color of fruits changed from green to yellow. In case of severe infestation the fruits turned brown. The infestation adversely affected the quality of seed and oil and ultimately reduced the fruit and oil yield.
