IRRADIATION OF SCORPIONS OF THE SPECIES CENTRUROIDES LIMPIDUS WITH GAMMA RAYS (in Spanish)
Although radiation studies have been done on other Arthropoda, mainly with the purpose of their eradication, little is known about the effect of gamma rays on scorpions. In this study, four groups of 15 scorpions each were irradiated with gamma rays varying in dosage from 4500 to 11,500 r. After a dose of approximates 4500 r, apparently normal physical activity and food intake were maintained. Longest survival time in this group was 105 days as compared with more than 8 months for the controls. The 8000-r dose produced immediate immobilization with subsequent development of sluggish movement. No food was taken and longest surviva) time was 33 days. After 10,000 r all movement stopped, all deaths occurring before 17 days. After 11,500 r there was no survival beyond 7 days. The survival time for a control group of 100 scorpions was over 6 months in spite of the high mortality figure for these arachnids in captivity. The results indicate a very high vulnerability in scorpions of this species to gamma radiation as compared with arthropods of the class Insecta, which appear to show a much greater resistance. (BBB)
