Changes in ornithine decarboxylase activity in response to temperature stress and stimulation of juvenile hormone in Anastrepha fraterculus (Diptera, Tephritidae).

Ornithine decarboxylase ( ODC) activity was analyzed in Anastrepha fraterculus (Diptera) females (4 days old) submitted to temperature stress (6 degrees C and 20/6 degrees C) and the topical application of juvenile hormone (JH). ODC activity and ejaculatory apodeme measurements (length and width) were made in males (15 days old) after 6 degrees C stress. JH dose of 500 ng and incubation of 3, 7, and 18 h increased ODC activity. Females reared at 6 degrees C and 20/6 degrees C had higher ODC activity than those reared at 25 degrees C. The treatment of 6 degrees C and JH incubation for 1 h increased ODC activity when compared to 6 degrees C treatments only. However, the treatment of 20/6 degrees C only after 3 or 18 h of JH incubation resulted in higher ODC activity than controls (20/6 degrees C) or 20/6 degrees C plus 1 h of JH incubation. Males did not undergo differences in ODC activity when reared at 6 degrees C or 25 degrees C but the ejaculatory apodeme measurements was higher in those reared at 25 degrees C than in those reared at 6 degrees C. The results can be considered an adaptive process to environmental changes.[1]
