其他摘要：Examination of old Sceliphron jamaicense (Fabr.) nests at 4 localities near the tip of the Baja California peninsula showed levels of brood success (i.e., the fraction of fully provisioned, closed cells producing viable adult offspring) between 24.6% and 58.1% per site. Failure was predominantly at the pupal stage at all localities. Successful cells are commonly reutilized by other solitary wasps, primarily Trypoxylon ( Trypargilum ) dubium Coville and Chalybion californicum (Sassure, 1867). There is a pronounced clumping tendency in successes and failures among nests.
