芒果实蝇是重要的检疫性有害生物,对芒果等寄主植物造成严重危害。本文报道了γ-射线对芒果实蝇的辐照效果。10、20、30、40、50、60、70、80、90、100、110、120、130、140和150Gyγ-射线辐照处理试验结果表明,≥70Gy剂量辐照处理下芒果实蝇成虫不能羽化。通过机率值分析,获得芒果实蝇辐照处理的LD99.9968为107.10 Gy(97.09,123.08)。在0～60Gyγ-射线辐照处理下,芒果实蝇老熟幼虫虽然不能100%死亡,但其羽化百分率、成虫寿命、产卵量和卵孵化率均随辐照处理剂量增大而降低。
Mango fruit fly is an important quarantine pest, causing serious damage to host plants such as mango. This paper reports the γ-ray irradiation on mango fruit fly. 10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 110, 120, 130, 140 and 150Gy γ-ray irradiation treatment results show that adults can not be mango fruit fly adult Feathering. Through the probability analysis, the LD99.9968 of the irradiated mango fruit fly was 107.10 Gy (97.09,123.08). Under 0 ~ 60Gy γ-ray irradiation, although mature larvae of M. mangifera could not die 100%, their percentage of emergence, adult longevity, egg production and egg hatching rate decreased with the increase of irradiation dose.
