Scientific name Odontotermes formosanus (Shiraki) isoptera, termite family. There are seven major termites that damage sugarcane: black-winged soil termites, domestic termites, yellow-winged termites, Hainan soil termites, yellow-legged termites, termite termites and termites. Among them, black-winged termites are more common. Distributed in Henan, Jiangsu, Anhui, Zhejiang, Hunan, Hubei, Sichuan, Guizhou, Fujian, Guangdong, Guangxi, Yunnan, and Taiwan.

Host sugar cane, peanuts, taro, fruit trees, rubber trees, fir, pine, eucalyptus and so on. The planting of sugarcane in Xinyidi was particularly affected.

Damage characteristics Termite feed stem tissue, the formation of multiple parallel tunnels with the sugarcane species, resulting in yellowing of the leaf color, ventilation easily inverted, resulting in whole plant withered. Morphological characteristics Termite colonies are divided into ant kings, queens, worker ants and soldiers. The soldier ants are 6mm long and 2.55mm long. Their heads are dark yellow, oval, long and wide. The widest part of the head is often in the posterior segment. The pharyngeal neck is slightly curved toward the head. There is 1 tooth in front of point. Body, wings dark brown. The distance between monocular and compound eyes is equal to or less than the length of the monocular eye. Antennas 15-17. The front of the thoracodorsal plate is narrow, obliquely tilted and wide at the back.

Living habits of winged adults occur in the nest in March, and they appear on the ground near the nests in April-June. There are 1 or more groups per nest and there are waiting rooms under the feather holes. Waiting room and the main nest 3-8m away. In the rainy days when the temperature is above 20°C and the relative humidity is higher than 85%, winged adults fly at around 19 o'clock. After the sub-fliers fly, the disemboweled adults generally drill into the ground to build a new nest. Workers have a very mixed diet. Sugarcane had two peaks of damage in the bud and in the middle and late stages of growth. The occurrence of termites is related to soil, vegetation, climate, temperature and humidity, age, methods, and varieties of vegetation.

Prevention methods (1) Use black light traps to kill termite fly seasons. (2) Use LD woodland termites trap package, 667m2 put 15-25 bags, from February to March, the ant nest was destroyed. (3) Deep plowing and soil reform in winter before sowing to destroy the nests. Seeds were soaked with 375-400% phoxim 75 per cent solution or 400 per cent with 40% methylisotriphos pump solution for 1-2 minutes. (4) After sowing, each 667m2 of 75% phoxim EC with 400-500g water 1000kg pouring in the cane ditch. In the period of July-October, when the sugarcane stem was found to be victimized, the above-mentioned liquid medicine could be poured and punched. In large soils, 3% methyl isofluosad granules can be used, 667m2 can be used with 4-6kg, sprinkled at the base of the planting cane seedlings, and then the soil can be effectively covered.
