How to control sugarcane aphids?

What are sugarcane aphids? How to control sugarcane aphids? Please introduce that sugarcane is vulnerable to cotton aphids in the middle and later stages of growth. Sugarcane aphids gather on both sides of the midvein on the back of the leaves to suck juice, wither and wither the leaves, excrete honeydew on the leaves, induce soot disease, affect the normal photosynthesis of leaves and reduce the yield and sugar content of sugarcane. The germination rate of damaged sugarcane shoots was low, and the persistent roots were poor. The generations of sugarcane aphids overlap and occur all the year round, starting from March to June, entering the peak period in July, and continuing until November and even the harvest period. The occurrence of cotton aphids is closely related to climatic conditions. generally speaking, cotton aphids develop slowly in the rainy season and spread rapidly in the dry season. Sugarcane aphids can be controlled with reference to the following methods: 1. Eliminate the source of overwintering insects. Remove overwintering parasitic reeds, weeds, etc., and spray on overwintering sugarcane fields to eliminate overwintering cotton aphids. 2. Protect natural enemies. The natural enemies of cotton aphids are double-star ladybug, 13-star lady beetle, aphid-eating gadfly, grass green ridge and so on, which should be protected. 3. Cut off the insect leaves. If the insect leaves are wiped or cut off manually, the sporadic leaves of woolly aphids can be wiped to death with cloth or cut off with leaves, and then trampled to death or burned out of the sugarcane field. 4. Chemical control. When the woolly aphid occurred in a punctate shape and caused less damage to sugarcane plants, 1 ∶ 10 dimethoate solution was used to coat the leaf marks at the base of sugarcane and green leaves. When cotton aphids have a wide range of damage, spray with 40% dimethoate 800 mi 1000 times, or 4.5% high efficiency cypermethrin 3000Mel 35000 times.
