摘 要 ：

研究了微波和电场对蒙古裸腹溞存活、生长和生殖的影响.结果表明: 35 s以上的2 450 MHz的微波辐照对蒙古裸腹溞的致死效应明显.短时间(<25 s)微波处理显著提高了蒙
古裸腹溞的每窝产幼量及一生产幼量，其中10 s微波处理组一生产幼量最高.微波处理使蒙
古裸腹溞的寿命显著延长(总寿命15.8～18 d).短时间的微波处理对幼溞的发育无显著影
响，但对成溞的生长具有一定的抑制作用.脉冲电场可大幅提高蒙古裸腹溞的一生产幼量,
其中29 kV·cm^-1的脉冲电场效果最佳; 高压静电场对蒙古裸腹溞的繁殖无显著影响.高压静
电场和脉冲电场对幼溞的发育均无显著影响，高压静电场对成溞的生长影响不明显，而脉冲
电场则对成溞的生长具有一定的抑制作用，且电压越高，抑制作用越明显.

Abstract:The study showed that 2 450 MHz microwave irradiation for 35 seconds o
r more had significant death effects on Moina mongolica Daday. Shortterm (less than 25 seconds) microwave irradiation could obviously increase the larvae number per clutch and the total fecundity over life span of the animal, with the highest fecundity under 10 seconds irradiation. Microwave irradiation could significantly prolong the life span (15.8-18 d) of M. mongolica. The short-term microwave irradiation had less effect on the development of larvae nimal, but inhibited the adult growth to some degree. Impulse electromagnetic field could significantly increase the fecundity of M. mongolica, with the highest effect of 29 kV·cm^-1; while high-voltage electrostatic field had less effect on the reproduction of M. mongolica. Both high-voltage and impulse electrostatic fields had no remarkable effects on the development of larvae animal. Highvoltage electrostatic field had lesseffect on the growth of adult animal; while impulse electromagnetic field had definite inhibition effect on it, and the inhibition effect was increased with increasing voltage.
