摘  要:
橘小实蝇是一种毁灭性果蔬害虫,本文研究了高能电子束对香蕉中橘小实蝇的致死效果,探索其用于防治和口岸检疫诊断的可行性。通过AB5.0~20x型电子直线加速器对香蕉中橘小实蝇的卵和幼虫、沙土中蛹辐照,辐照剂量为0、500、1000、1500、2000、3000Gy,结果显示高能电子束辐照对橘小实蝇卵、幼虫、蛹的LD50分别为879.8、2839.1、868.5Gy,表明幼虫对高能电子束的耐受能力较强。3000Gy能有效抑制卵的孵化(孵化率1.05%)、蛹的羽化(羽化率0),而幼虫致死率仅62.22%。高能电子束辐照效应还有待进一步研究优化。

摘  要:
Bactrocera dorsalis is a destructive pest that causes severe damage to the fruit and vegetable,this article studied the lethal effects of high energy electronic beam on the eggs and larvae in bananas and pupae in soil of Bactrocera dorsalis. By used of irradiation doses were 0,500,1000,1500,2000,3000Gy of AB5. 0- 20x electron linear accelerator,the LD50value of egg,larvae and pupae were 879. 8,2839. 1 and 868. 5Gy respectively. The results showed larvae were better tolerant to high electronic beam than eggs and pupae. The dose of 3000Gy can effectively inhibit the hatching of eggs( hatching rate: 1. 05%) and eclosion of pupae( eclosion rate: 0),but the motality of larvae was merely 62. 22%,Much more research should be proceed to improve the irradiation effects.
