regulates amino acid metabolism in edible insect : a functional metagenomics study.

Introduction: The soybean hawkmoth, , is an edible insect that possesses high nutritional, medicinal and economic value. It has developed into a characteristic agricultural industry in China.

Methods: The dominant gut bacterium in diapause larvae of soybean hawkmoths was identified by metagenomics, and the effect of diapause time on gut microbiome composition, diversity and function was investigated.

Morphological Characterization of the Antenna and Scent Patch of Three Species (Papilionoidea: Nymphalidae, Danainae).

The scent system of is important for the study of butterfly sexual communication and relevant investigations in biomimetics due to its involvement with mimicry. Using light, scanning, and transmission electron microscopy, the morphological characteristics of ' antennae and scent patches of the scent system for three species, , , and , were investigated herein. Their apical clubs of the flagellums contain sensilla trichodea, sensilla chaetica, and sensilla coeloconica.

Nutritional and Feeding Adaptability of Larvae to Different Cultivars of Soybean, ().

The larvae of , a special species of Chinese edible insect, are of great nutritional, medicinal and economic value to humans. This study aimed to clarify the effect of different soybean varieties (Guandou-3 (G3), Ruidou-1 (R1), September cold (SC)) on the nutritional quality and feeding selection behavior of larvae. The results showed that soybean isoleucine (Ile) and phenylalanine (Phe) were positively correlated with larval host selection (HS) and protein content.

() regulates the synthesis of linolelaidic acid and tricosanoic acid, and alters the key metabolites in diapause .

Good exploitation and utilization of edible insects can effectively alleviate global food security crisis in years. The study on diapause larvae of (DLC) was conducted to explore how gut microbiota regulate the nutrients synthesis and metabolism of edible insects. The results showed that maintained a total and stable nutrition levels at early phase of diapause.

Universal cooling patterns of the butterfly wing scales hierarchy deduced from the heterogeneous thermal and structural properties of Tirumala limniace (Lepidoptera: Nymphalidae, Danainae).

The radiative cooling of butterfly wing scales hierarchy has great value in understanding how poikilotherms adapt to the environment and developing bionic materials. However, it remains unclear what the cooling system is like and how the variation of hierarchy affects the cooling efficiency. Therefore, the correlation between the variations of the structure and emissivity of scale hierarchy is thoroughly investigated in Tirumala limniace (Cramer, 1775), whose thermal properties are highly heterogeneous among different wings and regions but similar between males and females.

Edible Aquatic Insects: Diversities, Nutrition, and Safety.

Edible insects have great potential to be human food; among them, aquatic insects have unique characteristics and deserve special attention. Before consuming these insects, the nutrition and food safety should always be considered. In this review, we summarized the species diversity, nutrition composition, and food safety of edible aquatic insects, and also compared their distinguished characteristics with those of terrestrial insects.

Nutritional Properties of Larval Epidermis and Meat of the Edible Insect (Lepidoptera: Sphingidae).

Insects represent a sustainable, protein-rich food source widely consumed in Asia, Africa, and South America. Eating Mell is common in the eastern part of China. A comparative characterization of nutrients in the meat and epidermis of was performed in this study.

Capacity for heat absorption by the wings of the butterfly (Cramer).

Butterflies can directly absorb heat from the sun via their wings to facilitate autonomous flight. However, how is the heat absorbed by the butterfly from sunlight stored and transmitted in the wing? The answer to this scientific question remains unclear. The butterfly (Cramer) is a typical heat absorption insect, and its wing surface color is only composed of light and dark colors.
