摘要
在温度T=(26±1)℃,相对湿度RH=(75±5)%条件下,室内饲养二斑叶螨(TetranychusurticaeKoch)的卵期4.57d,幼螨期1.93d,前若螨期1.90d,后若螨期2.52d,实验种群雌成螨的平均寿命15.96d,雌雄性比29∶7,单雌产卵量62.54粒。实验种群的内禀增长力为0.1566/d。在稳定种群年龄分布中,未成熟期占总量的93.01%,成熟期占6.99%。
Under the condition with the temperature(T) of (26±1)℃ and the ralative humidity(RH) of (75±5)% Tetranychus urticae (Koch) were reared indoors. The results showed as follows: length of egg period was in 4.57 d, larva in 1.93 d, protonympha in 1.90 d,deutonympha in 2.52 d, and life period of adult was in 15.96 d,♀/♂=29∶7,number of oviposition was 62.54 eggs/♀ .This paper dealed with the fecundity table of Tetranychus urticae (Koch),it turned the innate increase capacity (r_m)=0.1566/d. In age distribution of constant population ,the immature period was 93.01% and mature period was 6.99%.
