Abstract：
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.
摘要：
ClanisbilineataWalker（鳞翅目：Sphingidae），一种新兴的可食用昆虫，中国和其他地区的需求正在上升。尽管有这种兴趣,幼虫生产目前受到人工生产技术的限制，特别是最佳寄主植物的选择。这项研究严格评估了C.bilineatha幼虫在四种主要寄主植物上的表现：圆叶大豆，尖叶大豆,黑刺槐,还有Kudzu.优选试验表明，幼虫最容易被刺槐吸引(34.76±4.65%)，随后对葛根的偏好(25.00±6.12%)，圆叶大豆(23.17±2.79%),和尖叶大豆(14.02±4.74%)。圆叶大豆与刺槐或葛根之间没有明显的偏好差异。在喂养试验中，幼虫对圆叶大豆表现出明显的偏好(37.36±0.81克，幼虫的总摄食量)，其次是葛根(37.26±0.82克)，尖叶大豆(35.38±1.31克)，刺槐(28.53±0.81g)。当幼虫以圆叶大豆为食时，他们表现出明显更高的生存率（39.33±0.90％），体重(9.75±0.07g),总生物量（383.43±7.35g），化蛹率(87.78±1.73%)，与其他宿主相比，产蛋量（189.80±1.06卵/雌性）。这些发现发现，圆叶大豆显着提高幼虫的性能，表明其在培养系统中提高双歧杆菌幼虫产量和可持续性的潜力。
