Special Issue Information

Dear Colleagues,

The ability to produce insects has a broad impact on human lives in a wide array of areas including insect pest and weed management, human and veterinary medicine, insect production for food and nutrient supplements, as well as research and education. Ideal insect rearing technologies should allow to produce insects which are physically and behaviorally similar to those in Nature in simpler, highly controlled, cost-effective, and convenient ways. Newer multi-omics technologies (transcriptomics, nutrigenomics, proteomics, metabolomics, microbiomics, etc.) increased knowledge of microbiomes, and the manipulation of nutrigenomic analysis and statistical optimization modeling have enabled advances in insect diet formulation. These advances have resulted in a better understanding of the effects of food stream ingredients on insects’ physiological and biochemical functions, in addition to improving insect rearing systems and promoting the production of high-quality insects.

Considering the success of the earlier Special Issue "Focus on Insect Rearing Methodology to Promote Scientific Research and Mass Production", we are pleased to launch a Special Issue on Advances in Insect Diet and Rearing Methodology. Both original submissions and reviews will be considered for publication.

Bombyx mori is a model lepidopteran insect of great economic value. Mulberry leaves are its only natural food source. The development of artificial diets can not only resolve the seasonal shortage of mulberry leaves but also enable changes to be made to the feed composition according to need. Metabolomic differences between the midguts of male and female silkworms fed either on fresh mulberry leaves or an artificial diet were studied using liquid chromatography–mass spectrography (LC-MS/MS) analysis. A total of 758 differential metabolites were identified. Our analysis showed that they were mainly involved in disease resistance and immunity, silk quality, and silkworm growth and development. These experimental results provide insights into the formulation of optimized artificial feed for silkworms. Full article

Pollen is an important source of nutrition for bumblebees to survive, reproduce, and raise their offspring. To explore the nutritional requirements for the egg laying and hatching of queenright Bombus breviceps colonies, camellia pollen, oilseed rape pollen, apricot pollen, and mixtures of two or three types of pollen in equal proportions were used to feed the queens in this study. The results showed that the camellia pollen with a higher essential amino acid content was superior to the pollen with a lower essential amino acid content in the initial egg-laying time (p < 0.05), egg number (p < 0.05), larval ejection (p < 0.01), time of first worker emergence (p < 0.05), and the average weight of workers in the first batch (p < 0.01). It took less time for colonies under the camellia pollen and camellia–oilseed rape–apricot pollen mix treatments, both with a higher crude protein content, to reach ten workers in the colony (p < 0.01). On the contrary, the queens fed apricot pollen never laid an egg, and larvae fed oilseed rape pollen were all ejected—both pollens with a lower essential amino acid content. The results emphasize that the diet should be rationally allocated to meet the nutritional needs of local bumblebees at various stages when guiding them to lay eggs, hatch, and develop a colony.

The sweetgum inscriber, Acanthotomicus suncei (Coleoptera: Curculionidae: Scolytinae), is a recently discovered pest of American sweetgum planted in China, with a potential for causing a devastating invasion into North America. Research on the beetle has been hampered by a dwindling access to breeding material. We tested the effect of four artificial diets on A. suncei’s developmental time, length and weight of adults, egg hatching rate, pupation rate, and eclosion rate. Additionally, we evaluated the same parameters on A. suncei reared on American sweetgum logs. Only one diet supported the full development of A. suncei after 30 d. Beetles reared on this diet, which was made of small quantities of agar and additives (i.e., inositol, potassium sorbate, and methylparaben), supported the shortest developmental time of 45.55 ± 1.24 d. Beetles reared on American sweetgum logs exhibited a longer developmental time of 59.52 ± 4.52 d. Beetles reared on the artificial diet were markedly bigger and heavier than those reared on American sweetgum logs (p < 0.01). The egg hatching rate (58.90% ± 6.80%) and eclosion rate (86.50% ± 4.69%) of A. suncei on the artificial diet were significantly greater than those on sweetgum logs. However, the pupation rate (38.60% ± 8.36%) was much lower on the artificial diet than on the sweetgum logs. Here, we reported the best artificial diet for A. suncei and discuss the advantages and disadvantages over rearing the beetle on American sweetgum logs. Full article

The development of artificial diets could considerably simplify and reduce the cost of mass rearing of natural enemies compared to conventional rearing methods. However, improvement of artificial diets can be tedious, convoluted and often uncertain. For accelerating diet development, a better method that can offer informative feedback to target deficiencies in diet improvement is required. Our previous research demonstrated several biological characteristics were diminished in the insect predator, Arma chinensis Fallou, fed on an artificial diet formulated with the aid of transcriptomic methods compared to the Chinese oak silk moth pupae. The present study reports differential proteomic analysis by iTRAQ-PRM, which unravels the molecular mechanism of A. chinensis responding to improvements in the artificial diet. Our study provides multivariate proteomic data and provides comprehensive sequence information in studying A. chinensis. Further, the physiological roles of the differentially expressed proteins and pathways enable us to explain several biological differences between natural prey-fed and improved diet-fed A. chinensis, and subsequent proposed reformulation optimizations to artificial diets.
