A New practical Method for Profiling and Topping Up Alcohol Preserved Entomology Collections

Key aspects of recent research into topping up entomology spirit collections are summarised. A new method of profiling alcohol preserved collections is presented and its use as a diagnostic tool is discussed. A novel tool is also presented as a reference table for calculating the concentration of topping up alcohol, which allows the regulation of preservative alcohol concentration within close limits. The method can be used for remedial and routine topping up and can be adapted to the needs of different collections
