Abstract
Abstract Pepper weevil, Anthonomus eugenii Cano, is the major arthropod pest of peppers, Capsicum spp. L., in tropical and subtropical America. Adult weevils feed and oviposit in buds, flowers, and, especially, fruit. Larvae develop and feed inside those plant structures, thus reducing crop yields. Management is difficult and requires precise knowledge of developmental times and thresholds for maximum efficiency. Therefore, the developmental biology and life history parameters of A. eugenii were characterized in the laboratory on Capsicum annuum ’Jalapeno’ fruits at seven constant temperatures ranging from 15 to 33°C. A. eugenii developed through three instars at all temperatures. Linear regression analysis estimated a lower developmental threshold of 9.6°C and a degree-day requirement of 256.4 for development from egg to adult. Fecundity increased with increasing temperatures to a maximum at 30°C but declined at 33°C. Net reproductive rate (Ro), intrinsic rate of increase (rm), and finite rate of increas...
