Detailed Explanation of the Harm Caused by Sugarcane Termites and Control Methods
The main sugarcane termites are Odontotermes formosanus and Macrotermes barneyi. Sugarcane is subject to termite damage throughout its entire growth period, with the most severe damage occurring during the germination stage after planting. When attacking seed cane, they mostly invade through the cut ends at both sides, boring into and feeding on the internal tissues of the stem, preventing the seed pieces from sprouting.
