About This Project
Could Mealworms be used as an alternative to dermestid beetles for skeleton preparation? In museums, dermestid beetles can cause infestation problems and destruction of valuable collections if let loose. Through this experiment, we would like to find a way to reduce the chances of museum infestations and give amateur osteologists and hunters an easier way of processing animal materials to get clean skeletons.

What is the context of this research?
For years, museums have used dermestid beetles to remove residual tissue from skeletal preparations. The way in which these beatles eat the soft tissue resembles natural decomposition and is less damaging to small bones. However, these beetles can also become a hazard to museums, since they can consume skin collections and other museum displays.
There are chemical alternatives to the process of skeleton preparation, but they often leave skeletons weak and prone to breakage. We would like to find a way to limit the chance of infestation while creating a strong and long lasting skeletal display.
What is the significance of this project?
In 1950, a research study by E. Ross Allen and Wilfred T. Neil proposed Mealworms as an alternative to dermestid beetles for skull preparation because of these advantages: they are easy to get, require little care, can be kept in any contianer, and won't spread to infest valuable collections.
This research wasn't exhaustive and no published experimentation has been done since. We want to test their proposal and find out if mealworms can be used to remove flesh from osteological collections. If we find that they can be used for skeleton preparation, the method could be used by museums, hunters, and scientists all over the world as a safer easier alternative to dermestid beetles and chemical solutions.
What are the goals of the project?
The goal of this experiment is to find out if Mealworms can be used to prepare skeletal remains and determine the rate at which they can clean mammal skulls. We will do a pilot study to determine the number of mealworms needed to clean a mouse skull and the estimated rate of tissue removal per 1,000 mealworms. We will use 10 skulls.
The study will be done using 4000 Mealworms in a container. We will place a weighed skinned and defleshed mouse skull in the substrate. When it is clean it will be removed and weighed again. We will use the initial weight and clean weight to determine the rate of removal of flesh.
For this project we're going to use several thousand mealworms to clean out the skulls of 40 frozen mice. Other materials that we will need to carry out the experiment are dissection trays and kits, scalple blades, and a scale to determine how efficient mealworms are at removing residual tissue from the skull.
We will start by doing the skull preparations. We will then do a pilot study to confirm the findings of Allen and Neill 1950. The only scientific citation of using Mealworms in skull preparations. After doing our pilot experiment, we will collect the data for our study and we will end by writing a scientific paper outlining our findings.
