边缘Carpophilus marginellus是亚热带果树番荔枝和红叶的候选传粉者。在恒温18、20、25和30℃条件下，研究了该物种的发育时期和成虫大小，为其作为传粉者在温室中大量饲养和放生提供了基础资料。在所有温度下，光周期为16 h光照/8 h暗光照。温度越高，发育周期越短，成虫体型越小。25℃时死亡率最低，30℃时死亡率最高。不同发育阶段和性别的热阈值（发育零度）为11.9℃（雌幼虫）~ 15.6℃（雌蛹）。卵至成虫羽化期的总有效温度约为292℃。
Carpophilus marginellus is a candidate pollinator of the subtropical orchard trees cherimoya and atemoya. We investigated the developmental period and adult size of this species at constant temperatures of 18, 20, 25, and 30 degrees C as basic information for mass rearing and release in greenhouses as a pollinator. The photoperiod was 16-h light/8-h dark at all temperatures. The developmental period was shorter and the adult size was smaller at higher temperatures. Mortality was lowest at 25 degrees C and highest at 30 degrees C. The thermal threshold (developmental zero) ranged from 11.9 (female larvae) to 15.6 degrees C (female pupae) among developmental stages and sexes. The thermal constant (total effective temperature) of the period from egg to adult emergence was ca. 292 degree-days.
