Supplemental forage can be used to provide nutrition to bees during winter dearth. We examined the effects of supplemental forage on colony performance, colony survival, worker quality, and queen pheromone signaling in Nosema ceranae-infected overwintering colonies. Colonies were either supplemented with rapini or left unsupplemented for 1 mo before almond pollination. Unsupplemented colonies experienced higher mortality than supplemented colonies. Supplemental forage did not affect colony performance, worker mass, or hypopharyngeal gland protein content. However, supplemented queens released more of three queen QMP and QRP compounds (4-hydroxy-3-methoxyphenylethanol, Me oleate, and 1-hexadecanol) that promote queen care among workers. In addition, colonies that survived almond pollination thermoregulated their hives more than colonies that failed. Supplemental forage may prepare overwintering colonies for the stresses of early spring pollination. This study involved multiple reactions and reactants, such as 4-Hydroxy-3-methoxyphenethanol (cas: 2380-78-1Computed Properties of C9H12O3).
4-Hydroxy-3-methoxyphenethanol (cas: 2380-78-1) belongs to ethers. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits, including apples, durians, pears, bananas, pineapples, and strawberries. Many esters have the potential for conformational isomerism, but they tend to adopt an s-cis (or Z) conformation rather than the s-trans (or E) alternative, due to a combination of hyperconjugation and dipole minimization effects. The preference for the Z conformation is influenced by the nature of the substituents and solvent, if present. Lactones with small rings are restricted to the s-trans (i.e. E) conformation due to their cyclic structure.Computed Properties of C9H12O3
