Black soldier fly (BSF) larvae, Hermetia illucens L. (Diptera: Stratiomyidae), bio-convert organic side streams into high-quality biomass, the composition of which largely depends on the side stream used. In the present study, BSF larvae were reared on feed substrates composed of dried brewers’ spent grains, each supplemented with either water, waste brewer’s yeast, or a mixture of waste brewer’s yeast and cane molasses to obtain 12 different substrates: barley/water, barley/yeast, barley/yeast/molasses, malted barley/water, malted barley/yeast, malted barley/yeast/molasses, malted corn/water, malted corn/yeast, malted corn/yeast/molasses, sorghum-barley/water, sorghum-barley/yeast, and sorghum-barley/yeast/molasses. The crude protein, fat, ash, and mineral contents of the BSF larvae fed each feed substrate were quantified by chemical analyses. The effect of substrate, supplementation, and their interaction on crude protein, fat, and ash contents of BSF larval body composition was significant. Calcium, phosphorus, and potassium were the most abundant macrominerals in the larvae and their concentrations differed significantly among substrates. These findings provide important information to support the use of BSF larval meal as potential new source of nutrient-rich and sustainable animal feed ingredients to substitute expensive and scarce protein sources such as fishmeal and soya bean meal. 相似文献

In the present study a new species of the genus Anabolia, A. anatolica sp. n. from the Taurus Mountains in southern Anatolia is described and illustrated. The new species is related to A. laevis Zetterstedt, 1840 from northern Europe and is a glacial relict species of Pleistocene origin. 相似文献

We investigated insects associated with flowerfalls from seven tree species belonging to the Brazil nut family (Lecythidaceae) in the lowland rain forest of French Guiana. Freshly fallen androecia were collected from the forest floor and incubated in rearing chambers. Over 1300 insects representing 21 families were collected from the caged flowers, including abundant Diptera and Coleoptera, five moth morphospecies and four species of lycaenid butterflies. These insects feed on androecia. We also documented the presence of predators and parasitoids, indicating an additional trophic level. 相似文献
