雄性和雌性埃及伊蚊Aedes Aegypti(L.)用130mWAr 514.5 nm激光微束照射实验品系岩石蚊虫，照射剂量分别为0.04、0.25、0.4、0.5 S。用产卵量、孵化率和生产力(3wk后存活的平均成虫数量)来评估诱变效果。在所有激光辐射组中，男性的死亡率都很高，并且随着暴露时间的延长而增加。除了S剂量为0.25%的那一组，当父母亲暴露在激光辐射下时，所有其他实验者的F1后代总数也都显著减少。在S激光照射下，雌鼠死亡率较高。0.2 5、0.4、0.5 S照射亲本均不产生F1代，而0.0 4 S激光照射可显著减少F1子代的数量。每周平均子代数量的比较表明，当雄性或雌性成年亲本受到激光照射时，生产力的重要差异分别出现在第一周和第二周。
Male and femaleAedes aegypti(L.) mosquitoes of the laboratory strain ROCK were irradiated with 130 mw of argon 514.5 nm laser microbeams for 0.04, 0.25, 0.4, and 0.5 s, respectively. Egg production, percentage hatch, and productivity (average number of adults surviving after 3 wk) were used to assess mutagenic effects. Mortality was high for males in all laser radiation groups and increased with time of exposure. Except for the group treated for 0.25 s, significant reductions in total F1progeny also were demonstrated for all other experimentals when male parents were exposed to laser radiation. Females showed a high mortality when subjected to 0.4- and 0.5-s laser radiation. No F1progeny were produced when parental females were exposed for 0.25, 0.4, and 0.5 s. Numbers of F1progeny from females exposed to 0.04 s of laser radiation were significantly reduced. A comparison of weekly mean number of progeny showed that the important differences in productivity occurred during the first and second week, respectively, when either male or female adult parents were subjected to laser radiation.
