摘　　要：对原尾蜥虎 (Hemidactylusbowringii,Gray)的雌雄成体外形差异、性腺发育、产卵与孵化特性进行了观测。其雄性成体头部大于雌性成体。雌雄性腺发育具有较明显的季节性变化。雄性睾丸 5月为最大值 ,重量 2 2 5mg ,其长径为 7 2 8( 6 8～ 7 5 )mm ,短径为 4 2 9( 4 0～ 4 5 )mm ,8月降为最低值 ,重量 3 74mg,其长径为 4 62 ( 4 5～ 5 0 )mm ,短径为 1 2 2( 1 1～ 1 4)mm ;雌性产卵盛期 5～ 6月 ,一年一次性产卵 2枚 ,卵重 0 2 9( 0 2 4 8～ 0 32 5 )g,卵的长径为 9 5 8( 8 45～ 1 1 4)mm ,短径为 7 91 ( 7 70～ 8 41 )mm。孵化期 42～ 46d。 6月中旬出现当年幼体。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.
