Abstract The most serious borers of cultivated sugar-cane in Java were the striped borer, Proceras sacchariphagus Bojer, and the shining borer, Chilotraea auricilia Dudg. Other common ones were the grey borer, Argyroploce schistaceana Sn., and the purple borer, Sesamia inferens Walk. The first two almost exclusively tunnelled in young weak internodes and diminished their yield of sugar. They diminished the weight of younger internodes and the sucrose content of older internodes, even if they were not themselves infested. Infestation was assessed by the percentage of visibly infested parts. Few canes had to be checked and the method was reasonably accurate in the field.
Infestation varied between clones, and was higher with heavier N dressings and with rapidly growing good cane. It was probably associated with rind hardness and fibre content.

Control with insecticides was effective, especially if concentrated on the youngest leaves.
