Galleria mellonella (Lepidoptera: Pyralidae), the greater wax moth, is a major pest of stored or unattended beehive brood combs. The environment in which Galleria lives requires the continuous production of silk that is both strong and elastic; from the second instar onward, larvae produce large quantities of silk to construct feeding tubes which protect them from the bees. Continuous silk production differentiates Galleria from many other lepidopterans, where silk production is largely restricted to cocoon construction, and thus Galleria silk is a biological material worth investigating for many potential end-uses. To use this silk, the insects must first be euthanized and the cocoons dried to prevent spoiling in storage. The purpose of this study was to determine what effect the steps of freezing, thawing, and drying have on Galleria silk. The effects were evaluated visually using SEM and optical microscopy, and quantitatively using single-bave tensile strength tests.
