【摘要】 研究了60Co-γ射线辐照对黄曲条跳甲成虫取食能力和死亡率的影响。结果表明:经200 Gy60Co-γ射线辐照后15 d内,跳甲雌雄成虫死亡率较高,雌成虫和雄成虫累计死亡率分别达到61.67%和68.33%。相同辐照剂量下,雄成虫死亡率略高于雌成虫。辐照剂量在10~100 Gy范围内,对雌雄成虫的取食量影响较小。经200 Gy辐照后,雌雄成虫的取食量明显减少。相同辐照剂量处理后相同时间内,跳甲雌成虫的取食量高于雄成虫。更多还原

【Abstract】 The effects of 60Co-γ ray irradiation on the feeding ability and mortality of adults of Phyllotreta striolata were studied.The results showed that the mortality of adults of P.striolata was greatly influenced in 15 days after 200 Gy 60Co-γ ray irradiation,and the mortality rates of male and female adults were 61.67% and 63.33%,respectively.The mortality rate of male adults was higher than that of female adults under the same irradiation dose.10-100 Gy 60Co-γ ray irradiations had little effect on the feeding amount.The feeding amount reduced obviously after 200 Gy 60Co-γ ray irradiation,and that of female adults was higher than that of male adults in the same period under the same irradiation dose.更多还原
