概要

Catalase activity was qualitatively observed in two species of insects (Blattella germanica and Musca domestica) after different periods of immersion in a series of phosphate buffer solutions (pH 2.2, 3.0, 4.0, 5.0, 6.0, 7.0, 8.0). The catalase reaction was detected by dropping 3% hydrogen peroxide water solution on the crushed insect body. In B. germanica, catalase activity was lost after 10 days in the buffer solution at pH 2.2, 15 days at pH 3.0, 30 days at pH 4.0. The catalase activity was also lost after 20 days at pH 2.2 in M. domestica. On the other hand, the catalase activity was maintained for 30 days in B. germanica and M. domestica soaked in other solutions. The egg-cases of B. germanica immersed in each solution maintained the catalase activity for 30 days.
