Habitat Hummer is born in Guizhou for 13 generations. Overwintering adults are active in wheat fields in early March of the following year. They migrated to rice fields in early May. Rice earings are not mature. Adults migrate in large quantities to lay eggs and reproduce. They are the main pests in rice flowering stages. At an average temperature of 21-27°C, one generation was completed in 10-18 days. The average daily temperature was 17.2°C and the adult lived for 73 days. 27.2°C only survived 20 days. The worms and nymphs are more active and active in the heart and leaves. Their habitual sex is in the corn yellow peony. The worm mainly occurs before and after the corn trumpet period. In the middle and late June of the year in Beijing, there was frequent rainfall, heavy rainfall, and rapid decline of insect population. Indica tuber is born in Guizhou for 8 generations. It is wintered by the adults. It lays on the wheat flowering stage or just before the heading or earing ear of rice or on the corn tassel. Adults also like to move in the corn bell mouth. The droughty wheat field is an important source of insects for corn thrips, and the drought-fat fields are responsible for its occurrence and damage.

Prevention methods (1) The corn field adjacent to the wheat field should be strengthened with water and fertilizer management. When drought is found, timely watering and fertilizing can reduce the damage. (2) 20% butyl sulfide carbowax or 10% imidacloprid wettable powder, 1,8% albixine EC, and 10% demineralization 2000 times liquid in the land where the density of insect population is high or may occur. , 40% omethoate EC 1500 times, 25% Huifeng quick EC 1500-2000 times.
