Effect of the concentration of agar, alginate and carrageenan on the stability, toughness and nutrient leaching in artificial diets for abalone

Ciencias Marinas, 2001
In order to evaluate the effect of different binders on the quality of artificial diets for abalone in terms of stability, nutrient leaching and toughness, three phycocolloids (agar, alginate and carrageenan) were used at different concentrations (0.5%,

Dietary assessment across various life stages of seven-spotted lady beetle Coccinella septempunctata (Coleoptera: Coccinellidae)

Journal of Basic and Applied Zoology, 2023
Background Coccinella septempunctata (L.) is an important predator in fighting against aphids on edible crops and vegetables. However, to establish a successful mass-rearing technique, it is crucial to determine the optimal diets for larvae, pupae, and ...

Potential Involvement of Buchnera aphidicola (Enterobacteriales, Enterobacteriaceae) in Biotype Differentiation of Sitobion avenae (Hemiptera: Aphididae)

Insects
Buchnera aphidicola, an obligate endosymbiont of most aphid species, can influence aphids’ host adaptability through amino acid metabolism, potentially mediating biotype differentiation. However, its role in the biotype differentiation of Sitobion avenae

Does Larval Rearing Diet Lead to Premating Isolation in Spodoptera litura (Fabricius) (Lepidoptera: Noctuidae)?

Insects, 2021
Host plant preference during the larval stage may help shape not only phenotypic plasticity but also behavioral isolation. We assessed the effects of diet on population parameters and mate choice in Spodoptera litura.

Differential Proteomics Analysis Unraveled Mechanisms of Arma chinensis Responding to Improved Artificial Diet

Insects, 2022
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.

Validation of mobile artificial intelligence technology–assisted dietary assessment tool against weighed records and 24-hour recall in adolescent females in Ghana

, 2023
Background Important gaps exist in the dietary intake of adolescents in low- and middle-income countries (LMICs), partly due to expensive assessment methods and inaccuracy in portion-size estimation.
