In the middle and later stages of sugarcane growth, it is vulnerable to cotton aphids. If it is controlled in time, it will cause serious reduction of sugarcane production.
Sugarcane M. aphids clustered on both sides of the midrib veins of the leaves to suck sap, so that the cane leaves withered and withered, and the honeydew was excreted on the leaves to induce soy disease, affecting the normal photosynthesis of the leaves, and reducing sugar cane yield and sugar content. The seedlings of damaged sugarcane shoots have low germination rate, and the roots of perennial plants are poor. Sugarcane M. mori overlapped from generation to generation, occurred throughout the year, originated from March to June, and entered the peak period in July, continuing until November or even harvest. The occurrence of cotton aphids is closely related to the climatic conditions. Generally, in the rainy season, the development of cotton aphids is slow, and in the dry season it is rapid.
1, eliminate the overwhelming source of insects. Remove overwintering parasitic reeds, weeds, and other overwintering sugarcane fields to eliminate overwintering mites.
2, protect natural enemies. The natural enemies of cottonworm worms are double-star ladybugs, thirteen-star ladybugs, food crickets, grass green ridges, etc. and should be protected.
3, cut off the leaves. Artificially obliterate or excise the leaves of insects, and the sporadic leaves of M. aeruginosa can be wiped off with the cloth or even cut off by the leaves and taken out of the sugarcane field to be trampled to death and burned.
4, pharmaceutical control. Occurs in the form of spotted cotton. When the number of damaged sugarcane plants is small, a 1:10 dimethoate solution is used to ring the leaves of the cane stems and leaves of the green leaves. In the case of a relatively wide range of cottonworm locust damage, with 40% dimethoate 800-1000 times spray, can also use 4.5% high efficiency cypermethrin 3000-35000 times liquid spray.
