Abstract
The biological characteristics of Ambrostoma quadriimopressum were studied by breeding in the lab and observing in fields.The results show that the Ambrostoma quadriimopressum propagates has one generation in a year and it hibernates as imago.The larval stage has 5 instars,and the hatching stage is 8 days in condition of 15～21℃.While the larval stage is 18.5 days,the female imago spawns 19.46 eggs on average at one time,and spawns 678 eggs at a year under 19～26℃,the rate of hatchability is 98.06 percent.
