Maize is one of the main grains in southern Shanxi. In southern Jinmian cotton and wheat-growing areas, summer sowing crops are more than middle and late May. Intercropping with wheat or wheat in late June and late in mid- Severe insect damage, in the year of big occurrence, lack of seedlings serious, and even caused “destruction of species.” This insect has a long history in Jinnan.

About this worm research, the past few reports, in 1958 Wei Hongjun had introduced this worm. In the prevention and control, in recent years, many local people in the soil prior to sowing 0.5% 666 in the soil or seedlings sprinkled with 6% wettability of 666 200 times the root perfusion root soil, can receive some results.
