【目的】 洋虫Palembusder mestoides是一种药食兼用昆虫，应用潜力巨大，但产量低，规模小，产能不足。本研究旨在探究洋虫的最佳果蔬辅料方案，提高其繁殖能力。【方法】 开展7种果蔬辅料（橘皮、甜瓜、苹果、白菜、胡萝卜、南瓜和梨）全生命周期饲喂洋虫的研究，统计洋虫成虫产卵量、育成幼虫数量和化蛹数量等，分析洋虫不同虫态生长发育和全生命周期育成率。【结果】 甜瓜、苹果、胡萝卜和饲喂白菜（CK2）处理与不饲喂辅料（CK1）相比，均能有效缩短洋虫雌成虫的产卵前期、延长产卵期及提高单雌产卵量。甜瓜处理的产卵前期最短[（5.33±0.33）d]且产卵期最长[（133.00±4.04）d]，相比CK1处理产卵前期缩短3.34 d，产卵期延长24.00 d。甜瓜处理的单雌产卵量最多，达（231.98±15.19）粒，多于苹果处理74.00粒。取食苹果的处理20 d内（20头）幼虫总增重最大，达（103.34±19.85）mg，有效化蛹率和有效羽化率最高，分别达88.89%±2.94%和83.33%±1.93%，甜瓜处理表现次之。苹果和甜瓜的全生命周期育成率分别为54.64%±0.92%和52.05%±1.98%，显著高于其他处理（P<0.05），南瓜和胡萝卜处理的全生命周期育成率分别为41.54%±1.27%和37.42%±2.67%，橘皮处理的全生命周期育成率仅为16.27%±1.94%。【结论】 成虫期最佳辅料为甜瓜，幼虫期最佳辅料为苹果。按各虫期最佳果蔬饲喂，一对洋虫可产卵（305.80±10.82）粒，育成幼虫（259.05±13.69）头，繁育成虫（170.32±20.19）头。

 [Aim]  Palembus dermestoides is an insect with great potential for use as both medicine and food. However, it is currently underutilized due to low, modest-scale production with limited outputs. This study aims to determine the optimal fruit and vegetable supplementation regime for P. dermestoides and enhance its reproductive capacity. [Methods]  P. dermestoides were fed 7 different fruit and vegetable supplements (orange peel, cantaloupe, apple, cabbage, carrot, pumpkin, and pear) for one entire life cycle. Adult laying quantity, larval development quantity, and pupal quantity were measured to determine the growth and development of P. mestoides at different developmental stages and the overall life cycle breeding rate. [Results]  Compared to the CK1 control group (no supplemental feeding), P. dermestoides fed cantaloupe, apple, carrot, CK2 treatments（Feeding cabbage） had a shorter female pre-oviposition period, an extended oviposition period, and an increase in the quantity of eggs laid. The cantaloupe treatment group had the shortest pre-oviposition period [(5.33 ±0.33) d], but the longest oviposition period [(133.00±4.04) d]. The pre-oviposition period and oviposition period were 3.34 d shorter and 24 d longer, respectively, compared to the CK1. The cantaloupe treatment group had the highest single female laying quantity, with (231.98±15.19) grains, compared to the apple treatment group which laid 74.00 grains. Larvae fed with apples exhibited the largest total weight gain within 20 days (20 individuals), reaching (103.34±19.85) mg. Additionally, the apple treatment group had the highest effective pupation rate and effective eclosion rate, reaching 88.89%±2.94% and 83.33%±1.93%, respectively, followed by the cantaloupe treatment group. The overall life cycle breeding rates for the apple and cantaloupe groups were significantly higher than the other groups with rates of 54.64%±0.92% and 52.05%±1.98%, respectively. The overall life cycle breeding rates for the pumpkin and carrot treatment groups were 41.54%±1.27% and 37.42%±2.67%, respectively（P<0.05）. The overall life cycle breeding rate of the orange peel treatment was the lowest at 16.27%±1.94%. [Conclusion]  The results of this study indicate that cantaloupe and apple are the most effective supplements during the adult and larval stages, respectively. Feed with the best fruits and vegetables for each insect stage, a single pair of P. dermestoides can lay (305.8±10.82) eggs, hatch (259.05±13.69) larvae, and ultimately produce (170.32±20.19) high-quality adults.
