Nosema ceranae is a microsporidian parasite that threatens current apiculture. N. ceranae-infected honey bees (Apis mellifera) exhibit morbid physiological impairments and reduced honey production, malnutrition, shorter life span, and higher mortality than healthy honey bees. In this study, we found that dimethyl sulfoxide (DMSO) could enhance the survival rate of N. ceranae-infected honey bees. Therefore, we investigated the effect of DMSO on N. ceranae-infected honey bees using comparative RNA sequencing analysis. Our results revealed that DMSO was able to affect several biochemical pathways, especially the metabolic-related pathways in N. ceranae-infected honey bees. Based on these findings, we conclude that DMSO may be a useful alternative for treating N. ceranae infection in apiculture.

Flavonoids have multiple functions, including host-plant defense against attacks from herbivorous insects. This manuscript reviewed and analyzed the scientific literature to test the hypothesis that flavonoids can be utilized to manage pests without causing significant harm to beneficials. The methodology involved using recognized literature databases, e.

Climate change significantly affects honey bee populations and their access to natural food sources, demanding alternative economic feed sources. Longan stands out as the most important fruit crop in Southeast Asia, but with a surplus of low-grade fruit that is not suitable for the market. This study investigates the potential of longan syrup as an alternative carbohydrate source for honey bees by measuring sugar composition, phytochemical profiles, feed, and survival, as well as the resulting gut microbial changes.

Honey, a natural food with a rich history, is produced by honeybees and other species of bees from nectar, other plant fluids, and honeydew of sap-sucking insects. During foraging, these bees may be exposed to plant protection products (PPPs), metals, and metalloids, potentially leading to residues in honey and hive products that could have a negative impact on human safety. Recognizing the lack of an appropriate methodology for pesticide contamination of honey and other hive products, this research aims to support the need for studies on residues in pollen and bee products for human consumption to establish safe maximum residue levels (MRLs) for consumers.

The most common bee species used for honey production is (), followed by stingless bees. This study included scientific articles using the PRISMA approach. A random effect model was implemented and the effect size (ES) was calculated and reported as the standardized mean difference (SMD) and raw mean difference (RMD).
