Abstract

When larvae and adults of Tenebrio molitor L. were exposed at sublethal levels to 39-MHz radiofrequency (RF) electric fields, the RF treatment of last-stage larvae and adults reduced female fecundity. The reduction fecundity was more pronounced with longer periods of exposure and higher electrode voltages. The effect of RF energy on fecundity was more dependent upon treatment of males than upon treatment of females. Exposure of larval stages to RF energy resulted in a reduction in both the size of the ovaries and the number of eggs which developed in females that emerged from treated larvae.
