| Abstract: | The breeding habits of Hemidactylus bowringii ,Gray was invastigeted.The adult male's head is bigger than the female's.The size of sexual gland changes seasonally.In May the male's testis reaches its maximum,with weights being 22.5 mg in average, the long diameter being 7.28(6.8～7.5)*!mm and the short diameter 4.29(4.0～4.5) mm. In August testis is at its minimum with the weights being 3.74 mg, the long diameter being 4.62(4.5～5.0)mm and the short diameter 1.22(1.1～1.4) mm. The females lay eggs mainly in May and June. It lays 2 eggs per year.The egg weighs 0.2941(0.248～0.325) g The long diameter of the egg is 9.58(8.45～11.4)mm.Its short diameter is 7.91(7.70～8.41) mm.The incubation needs 42～46 days.The egg will hatch in the middle of June. |
