Abstract

The effects of acute gamma-irradiation on the Colorado potato beetle (Leptinotarsa decemlineata Say) and sensitivity of insects, long time exposed on radioactively contaminated territories, to pesticides were studied. LD50 values of insects to ionizing radiation during the ontogenesis process was shown to increase (from 8 to 48 Gy). Differences were noted in the development rates of the natural population of beetles collected on agricultural lands with 137Cs contamination density of 0.05-1.2 MBq/m2, with the sensitivity to various pesticide groups being the same.

摘要

研究了急性γ射线辐照对科罗拉多马铃薯甲虫（Leptinotarsa decemlineata Say）的影响，以及长期暴露在放射性污染区域的昆虫对杀虫剂的敏感性。结果表明，昆虫在个体发育过程中对电离辐射的半数致死剂量（LD50）值增加（从8戈瑞增加到48戈瑞）。在137Cs污染密度为0.05 - 1.2兆贝克勒尔/平方米的农田采集的甲虫自然种群的发育速率存在差异，但其对各类农药组的敏感性相同。
