摘要： Clanis bilineata Walker (Lepidoptera: Sphingidae), a burgeoning edible insect, is experiencing rising demand in China and other regions. Despite this interest, larval production is currently constrained by the limitations of artificial production technologies, particularly the selection of optimal host plants. This study rigorously evaluated the performance of C. bilineatha larvae on four main host plants: round-leaf soybean, pointed-leaf soybean, black locust, and kudzu. Preference tests demonstrated that the larvae were most attracted to black locust (34.76 +/- 4.65%), with subsequent preferences for kudzu (25.00 +/- 6.12%), round-leaf soybean (23.17 +/- 2.79%), and pointed-leaf soybean (14.02 +/- 4.74%). No significant preference differences were noted between round-leaf soybean and either black locust or kudzu. In feeding assays, the larvae exhibited a marked preference for round-leaf soybean (37.36 +/- 0.81 g, total feeding amount for larvae), followed by kudzu (37.26 +/- 0.82 g), pointed-leaf soybean (35.38 +/- 1.31 g), and black locust (28.53 +/- 0.81 g). When the larvae were fed on round-leaf soybean, they exhibited significantly higher survival rate (39.33 +/- 0.90%), body weight (9.75 +/- 0.07 g), total biomass (383.43 +/- 7.35 g), pupation rate (87.78 +/- 1.73%), and egg production (189.80 +/- 1.06 eggs/female) compared to other hosts. These findings uncovered that round-leaf soybean significantly enhances larval performance, suggesting its potential for improving C. bilineata larval production and sustainability in cultivation systems.
