"Histology, ultrastructure and morphological arrangement of male and female reproductive system of Aphelocheirus aestivalis (Fabr.) have been studied in nymphs of instar 1 - 5 and variously aged apterous adults. Testicular follicles and ovarioles start to differentiate in instar 2 and their entire differentiation is finished in instar 3. Paired accessory mesadenia dichotomically branched in adult males differentiate in instar 2 as well. The anlage of male ectodermal accessory gland is formed during instar 3, spermatheca and bursa copulatrix start to invaginate in instar 4. Similarly, differentiation of germ cells as well as formation of the germarial trophic core are described. The timing of crucial reproductive processes (permanent spermatogenesis and oogenesis ceased only in winter) seems to be rather different from those most of aquatic bugs showing a clear tendency to semivoltinism." . . . .
