γ-射线对荔枝蒂蛀虫卵和蛹的杀虫效应(英文)

EFFECTS OF GAMMA IRRADIATION ON LITCHI STEM-END BORER EGGS AND PUPAE

应用0．25～0．60kgy的^(60)Co-射线对荔枝蒂蛀虫ConopomorphasinensisBradley卵和蛹进行了辐照处理的研究，结果表明，卵的孵化率随辐照剂量的增加而降低。0．60kGy辐照后，卵不孵率和幼虫死亡率达93．64％。前期蛹比4～5天龄的蛹对γ-射线敏感。经0．50kGy辐照后，供试的前期蛹不能羽化为成虫，经0．50和0．60kGy辐照4～5天龄的蛹后，蛹的羽化率分别为74．93％和67．68％，而且羽化出来的成虫为不育成虫。
