Abstract

We have been studying the mitotic activity of the hemocytes and the protein concentration of the hemolymph of the milkweed bug, Oncopeltus fasciatus (Hemiptera: Lygaeidae) to see wheter and how they reflect stress situations of changes in the insect's environment. To study the effects of a high altitude on the milkweed bug we took stock cultures of the bug from our laboratory at St. Louis (elevation approximately 600 feet) to the Jackson Hole Station (elevation 6,750 feet). Project Number 141.
