Integrating plant production with insect farming, termed "entomoponics," involves using plant waste as a substrate for insect rearing, while returning insect frass to fertilise the plants. In this study, vegetative wastes from strawberry (Fragaria x ananassa), and common bean (Phaseolus vulgaris), were incorporated into a wheat bran-based substrate for rearing the yellow mealworms (MW; Tenebrio molitor). The wastes were either autoclaved or autoclaved then fermented with the fungus Trichoderma reesei, and mixed in a 50:50 ratio with wheat bran. Replacing 50% of the wheat bran with autoclaved beans waste did not significantly affect MW yield, but the yield was reduced when beans wastes were fermented or left untreated. Incorporating beans waste, whether treated or untreated, increased the Ca, K, and Fe content in the MW. Incorporating strawberry vegetative waste into the substrate compensated the yield regardless of the pre-treatment, but enhanced Mn, Zn, and Fe levels in the produced MW. Plant flavonoids were reduced when the wastes were pre-treated and did not accumulate in the MW biomass. These findings provide insights into using plant vegetative wastes as a partial supplement in MW rearing substrates, and the potential effects on the growth and nutritional composition of the resulting MW biomass.
将植物生产与昆虫养殖相结合，即所谓的“昆虫种植法”，涉及利用植物废料作为昆虫饲养的基质，同时将昆虫粪便返还给植物作为肥料。在本研究中，草莓（凤梨草莓）和菜豆（菜豆）的营养废料被掺入以麦麸为基础的基质中，用于饲养黄粉虫（MW；黄粉虫）。废料要么经过高压灭菌，要么经过高压灭菌后再与里氏木霉进行发酵，并与麦麸以50:50的比例混合。用经过高压灭菌的豆类废料替代50%的麦麸对黄粉虫产量没有显著影响，但当豆类废料经过发酵或未处理时，产量会降低。掺入豆类废料，无论是否经过处理，都会增加黄粉虫体内的钙、钾和铁含量。将草莓营养废料掺入基质中，无论预处理如何，都能补偿产量，但会提高所产黄粉虫体内的锰、锌和铁含量。当废料经过预处理时，植物类黄酮会减少，并且不会在黄粉虫生物量中积累。这些发现为将植物营养废料用作黄粉虫饲养基质的部分补充以及对所得黄粉虫生物量的生长和营养成分的潜在影响提供了见解。
