Since Fye and Medler (1954) described methods of obtaining establishment of bumble bee queens in artificial domiciles in Wisconsin, we have been obtaining colonies for pollination and food-preference studies by similar means. The following is a summary of our experiences with the Fye-Medler type of above-ground domicile. Most of the trials were conducted in the prairie region of southern Alberta with grassland species of bumble bees; one was conducted in the foothills of the Rocky Mountains in southern Alberta, where species peculiar to treed areas are common. Because bumble bee queens make their nests in deserted mice nests, domiciles with entrance holes 1 ¼ inches in diameter were partly filled with roughed-up flax straw and set out in the fall to first provide homes for mice. The following spring, the mice were expelled and mice-excluders (thin metal plates 2 inches square, with holes 5/8 inch in diameter) were nailed over the original holes (cf. Fye and Medler, 1954).

Dic Technique

In this paper, the dynamic deformation and rupture of pre-notched thin metal plates subjected to confined blast loading were investigated. The thin copper plates with cross-shape pre-notch were clamped on the end of a confined cylinder vessel by a cover flange. An explosive charge with a mass of 4g was detonated in the vessel center to generate blast load acting on the metal plates. The images of metal plates were recorded by two high-speed cameras. The displacement and strain fields during the deformation and rupture process were measured by using 3D digital image correlation (3D DIC). The effects of pre-notches on the dynamic deformation and rupture of thin metal plates were analyzed. The microstructure of fracture surface was examined The 3D DIC technique is proven to be an effective method to conduct dynamic full-field deformation measurement.
