Influence of Different Diets on Growth and Development of Eastern Honey Bee ().

In recent years, honey bees have been stressed by multiple factors, with malnutrition posing a significant threat to the healthy development of honey bee colonies. To keep a colony healthy and productive, beekeepers supply their colonies with supplementary pollen or commercial pollen substitutes during periods of pollen dearth or insufficient pollen quantity or quality. In this study, we evaluated the effects of four natural pollen types (oilseed rape pollen, camellia pollen, lotus pollen and buckwheat pollen) and two commercial pollen substitutes (Diet 1 and Diet 2) against a control group (sucrose solution) on through cage experiments.

Dual-conjugation of aminated sugar beet pectin-oxidized tannic acid nanonetworks with cinnamaldehyde at the oil-water interface to stabilize a 3D printable high internal phase emulsion.

The morphological features and interactions among the assembly units of nanoparticles (NPs) significantly influence their ability to stabilize Pickering emulsions. In this study, the quinone group of oxidized tannic acid (OTA) was covalently cross-linked with the amino groups in aminated sugar beet pectin (SBP-NH) to form covalent composite nanonetworks (SBP-NH/OTA NNs). These NNs were subsequently conjugated with cinnamaldehyde (CA) to enhance interfacial activity, enabling the formation of 3D printable high internal phase emulsions (HIPEs).
