Hæmocyte Counts on the Large Milkweed Bug, Oncopeltus fasciatus


THE increasing interest in biological means of controlling insects intensifies the need for investigations of the response of insects to disease organisms and foreign proteins. The hæmolymph, the hæmocytes in particular, offers a readily accessible criterion of response. For work on responses of insects to be meaningful, the normal laboratory insect should be examined thoroughly throughout its life. It was decided to use the milkweed bug (Oncopeltus fasciatus: Hemiptera, Lygaeidae) as the experimental animal in these investigations because it represents a relatively important group of plant-sucking insects and it can be reared easily in the laboratory throughout the year.
