Studies were conducted on the effects of sublethal doses of an organophosphate, Parathion, a chlorinated hydrocarbon, Dieldrin, and a carbamate, Sevin, on the acoustical and sexual behavior of Acheta domesticus L. The LD of orally administered Parathion was 0.100 μg/g, that of Dieldrin was 0.066 μg/g, and that of Sevin was 0.330 μg/g. Parathion treated crickets were unable to emit pure calling, threat, or courtship songs. As a result of these changes in acoustic behavior, treated male crickets were unable to complete copulation.Oral administration of both Dieldrin and Sevin resulted in complete cessation of singing in all specimens for 3 to 6 hours. Once singing resumed there was a significant increase in chirp rate and pulse rate of the calling song.It is suggested that sublethal doses of Parathion act primaily on the peripheral neuromuscular system and the thoracic ganglia, whereas both Dieldrin and Sevin appear to act upon components of the brain, first in an inhibitory capacity and subsequently as excitants.
研究了亚致死剂量的有机磷酸酯对硫磷、氯代烃狄氏剂和氨基甲酸酯西维因对家蟋蟀声学和性行为的影响。经口给予对硫磷的半数致死剂量为0.100μg/g，狄氏剂为0.066μg/g，西维因是0.330μg/g。用对硫磷处理过的蟋蟀无法发出纯正的求偶、威胁或求爱之歌。由于这些声学行为的变化，经处理的雄性蟋蟀无法完成交配。经口给予狄氏剂和西维因均导致所有样本在3至6小时内完全停止鸣叫。一旦鸣叫恢复，求偶之歌的啁啾率和脉冲率会显著增加。研究表明，亚致死剂量的对硫磷主要作用于外周神经肌肉系统和胸神经节，而狄氏剂和西维因似乎都作用于大脑的某些成分，首先具有抑制作用，随后表现为兴奋作用。
