采用酶组织化学方法研究了棉铃虫中肠三磷酸腺苷酶、酸性磷酸酶和碱性磷酸酶的分布和活性。结果显示三种酶在棉铃虫中肠均有分布，但分布部位各不相同，其中，三磷酸腺苷酶在肠壁分泌细胞、肠壁细胞、环肌和纵肌均有分布，以肠壁分泌细胞活性较高；碱性磷酸酶主要分布于肠壁分泌细胞，在肠壁分泌细胞做绒毛处活性最高；酸性磷酸酶分布于肠壁细胞、环肌和纵肌，在肠壁细胞底膜处活性最高。这些酶可以作为棉铃虫中肠不同条件下的生理指标。
The distribution and activity of adenosine triphosphate, acid phosphatase and alkaline phosphatase in the midgut of cotton bollworm were studied by enzyme histochemistry. The results showed that the three enzymes were all distributed in the midgut of H. armigera but distributed differently. Among them, adenosine triphosphate (ATP) was distributed in the secretory cells of intestinal wall, intestinal wall cells, Were higher than those in the control group. Alkaline phosphatase was mainly distributed in the secretory cells of intestinal wall and the highest was found in the secretory cells of secretory cells in the intestinal wall. Acid phosphatase was distributed in the intestinal cells, . These enzymes can be used as physiological indicators of Helicoverpa armigera in different conditions.
