Exploring the Life Cycle of Bactrocera latifrons: A Detailed Age-Stage, Two-Sex Life Table

<i>Bactrocera latifrons</i> (Hendel) is a serious pest requiring quarantine in many countries worldwide. It has caused huge economic losses to the cultivation of solanaceous plants, such as peppers and eggplants. In this study, we constructed an age-stage, two-sex life table using eggplant as the host to clarify the occurrence and damage patterns of <i>B. latifrons</i> on this crop for better field prevention and control in the laboratory. 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. We established the life table based on group rearing. The research findings provide essential data for rearing <i>B. latifrons</i> in the laboratory, offer a reference for the dynamic prediction of field population dynamics, and offer a theoretical foundation for developing pest control strategies for <i>B. latifrons</i>.
