以罩笼接虫法研究了棉株喷施缩节安对棉铃虫幼虫存活、发育及其危害的影响。结果表明；喷施缩节安可明显降低棉株上棉铃虫幼虫的存活及危害；但对幼虫的发育表现出低龄抑制而高龄促进的趋势，对棉铃虫不同龄期幼虫具有不同的影响。
The effects of sprayed acetaminophen on the survival, development and the damage of cotton bollworm larvae were studied by means of a cage cocooning method. The results showed that sprayed acetaminophen significantly reduced the survival and damage of cotton bollworm larvae on cotton plants, but showed a tendency of low-age inhibition and aging promotion to larvae, which had different effects on larvae of different instars.
