The bioaccumulation of pesticides in honeybee products (HBPs) should be studied for a number of reasons. The presence of pesticides in HBPs can provide new data on the risk related to the use of pesticides and their role in bee colony losses. Moreover, the degree of contamination of HBPs can lower their quality, weaken their beneficial properties, and, in consequence, may endanger human health.

Long non-coding RNAs (lncRNAs) are emerging as critical regulators in honeybee physiology, influencing development, behavior, and stress responses. This study investigates the role of lncRNA LOC113219358 in the immune response and neurophysiological regulation of brains. Using RNA interference (RNAi) and RNA sequencing (RNA-seq), we demonstrate that silencing lncLOC113219358 significantly alters the expression of 162 mRNA transcripts, including genes associated with detoxification, energy metabolism, and neuronal signaling.

Purpose: Encephalitozoon intestinalis is an obligate intracellular microsporidian fungus that causes severe gastrointestinal infections, particularly in immunocompromised individuals. Propolis (PROP), a resinous substance derived from bees, has antimicrobial, anti-inflammatory and antioxidant properties, while royal jelly (RJ) has immunomodulatory, antioxidant and antimicrobial activities. The aim of this study was to investigate the therapeutic potential of PROP and RJ against E.

10-hydroxy-2-decenoic acid (10-HDA), a unique unsaturated fatty acid present in royal jelly, has attracted considerable interest due to its potential medical applications. However, its low concentration in royal jelly and complex conformational structure present challenges for large-scale production. In this study, we designed and constructed a de novo biosynthetic pathway for 10-HDA in Escherichia coli.
