“…In order to investigate various supplementary feeds, aloe (Saponaria), apple (Busa), banana (Cavendish), sweet persimmon (Buyoo) and sweet pumpkin (Danhobak) were purchased from a traditional market in Korea. Supplementary feeds were sliced into 3 mm sections and positioned on top of fermented sawdust once a week (10, 15, or 20 g depending on the larval growth stage; Yoon et al, 2016). Remaining supplementary feed was removed 48 h after feeding.…”

“…P. brevitarsis have been successfully reared in an artificial breeding environment (Park et al, 1994) and their morphology and growth characteristics have been examined (Kang et al, 2005;Kim, 2005;. In addition, feeds that are important during the rearing process have been studied with a fermented aloe replacement resource (Kang, 2011) and various supplementary feeds (Yoon et al, 2016), however, these studies have not comprehensively evaluated nutritional content.…”

The goal of this study was to evaluate the influence of various supplementary feeds on the chemical composition and production of bioactive substances in Protaetia brevitarsis larvae. The primary feed-oak-fermented sawdust-was supplemented with a variety of substances, including aloe, apple, banana, sweet persimmon (S. persimmon) and sweet pumpkin (S. pumpkin). Crude protein and fat content were the highest in the control and S. pumpkin group, respectively. Supplementary feeds increased the content of unsaturated fatty acids, except in the group receiving S. pumpkin, in which oleic acid was the most abundant (58.2%-64.5%). Free essential amino acids in larvae receiving supplementary aloe were higher compared with the control group except for Lys and His. Polyphenol and flavonoid contents and the antioxidant activities of ABTS and DPPH were higher in all treated groups compared with the control group. Although supplementary feeds led to a decreased crude protein content in the treated larvae when compared with the control group, these treatments generally improved the levels of unsaturated fatty acids and antioxidative activity. Therefore, we suggest that among the supplementary foods tested, aloe is a better resource for P. brevitarsis based on crude protein content, free amino acids and other bioactive compounds such as unsaturated fatty acids and antioxidants.

“…Moreover, since the pretreatment conditions needed to utilize Pbl as a food ingredient were defined by Kwon et al (2013), the Ministry of Food and Drug Safety (MFDS) approved its use as food from October 2014 onward. Pbl can now be manufactured and marketed as food in the Republic of Korea (Yoon et al 2016).…”

To develop a system for the mass production of Protaetia brevitarsis larvae (Pbl), this study analyzed the oviposition characteristics of third instar Pbl through successive rearing and cold treatments. In the first generation, females laid 50 eggs each on average, and spawned higher numbers of eggs for the first 5 days but then fewer after this. However, all of the 2nd‐generation females that were produced through the successive rearing of eggs from the 1st generation did not spawn. When test insects (TI) were raised at 32°C, their mean ± SE pupal period and emergence rate were 28.4 ± 1.9 days and 87%, respectively. However, most individuals raised in cold treatments (5°C and − 5°C) without a pre‐cooling period did not survive. Individuals exposed to a pre‐cooling period, however, had a 7–10 days longer pupal period than those raised at 32°C, and their emergence rate (90%) was slightly higher. Different cold treatment temperatures (0°C, 3°C, or 5°C) and periods (30 or 60 days) were tested in further experiments. The experimental group kept for 30 days at 0°C and 3°C had the shortest pupal period of all, and emergence rates exceeded 90% in most groups. With respect to the number of eggs spawned by the second generation females after cold treatments, the experimental groups held in cold treatments at 5°C for 30 and 60 days were found to spawn the most eggs. Consequently, the experimental group kept at 5°C for 30 days was the most effective set of conditions tested during the entire breeding period.
