Changes in acid phosphatase activity in 6 tissues of the fifth instar milkweed bug, Oncopeltus fasciatus

Acid phosphatase activity in the hemolymph and cuticle was higher during the early part of the fifth instar than at any other time. The enzyme activity in the fat body, testes, salivary glands, and midgut was statistically the same throughout the instar.
