After the bud is injured, it is very easy to change color and fall off. Sometimes the growth point of the stem was broken, which affected the normal growth of sesame. In severe cases, only the bare rod and a few malformed capsules were left in the later stage of the injured plant, resulting in a significant reduction in yield. Overwintering with eggs on weeds usually begins in late June, and the peak period of damage is from July to August. That is, the damage is the most serious before and after budding and flowering of sesame. It can occur 1-4 generations a year, there is generation overlap, and can spread viruses and other diseases. The control methods of aphids and blind bugs are as follows: (1) remove weeds and eliminate the source of Zhaodong insects in autumn and winter. (2) good results can be obtained by spraying 40% omethoate 1000-1500 times, 4.5% cypermethrin 2000 times and 10% imidacloprid 2000 times when it occurs in the field.
