Simple Summary Bactrocera latifrons has caused great losses to peppers, eggplants, and tomatoes, which have always been favored by people as fruits and vegetables. In recent years, this pest has been intercepted in fruits and vegetables imported from other countries at many ports in China, indicating that the risk of B. latifrons spreading along with its hosts is very high, and thus should attract wide attention. To conduct a risk assessment of B. latifrons, it was group-reared with eggplant as the host, and an age-stage two-sex life table was adopted to explore the growth and development indexes and population parameters of B. latifrons. The results showed that the egg, larval, and pupal stages lasted 4.3, 11.3, and 9.3 days, respectively. The average lifespan of adult females and males was 101 and 102 days, respectively. The egg hatching rate, larval survival rate, and pupal emergence rate were 96%, 88%, and 84%, respectively. The average generation time was 43.96 days, with an intrinsic rate of increase of 0.097 d−1 and a net reproductive rate of 73.4. This study provides a basis for the monitoring of B. latifrons and the formulation of effective control strategies.
