摘要:

A life table was developed for two consecutive univoltine generations of the red sunflower seed weevil,Smicronyx fulvusLeConte, a major pest of cultivated sunflower in North Dakota. A mean mortality of 86.9% for fifth instar and pupa in the soil was the highest for all life stages. A 94.6% generation mortality indicates a slightly declining weevil population for the two years of the study.
