摘要：本文分析了 4组不同湿度和 3组光照条件下桑白盾蚧 Pseudaulacapis pentagona(Targioni-Tozzetti)的种群生长状况;组建生命表。相对湿度在 55%;77%;80 %;95%时;种群的内禀增长率分别为 :- 0 .0 0 57,0 .0 510;0 .0 50 8,0 .0 0 94;净增殖率分别为 :0 .6 92 0;2 7.2 10 0;2 7.6 6 80;1.86 0 6;后 3者世代增倍时间分别为 13.5910;13.6 4 4 6;73.7391天;光周期在 L∶D=14∶ 10;12∶ 12时;种群内禀增长率分别为 :0 .0 4 4 5,0 .0 334,净增殖率分别为 2 3.96 2 8,12 .156 2;增倍时间为 15.576 3,2 0 .752 0天;而 L∶D=10∶ 14时;净增殖率为 0;内禀增长率和增倍时间都不存在;种群将消亡。

Abstract: The influences of humidity and photoperiod on the population growth of Pseudaulacapis pentagona (Targioni|Tozzetti) were studied in the laboratory. Life tables, at 55%, 70%, 80%, 95% RH and under three photoperiods (L∶D=14∶10, 12∶12, 10∶14) were constructed. According to the life tables, at 55%, 70%, 80%, 95% RH, its net reproduction rates ( R-0 ) are 0 6920, 27 2100, 27 6680 , 1 8606 respectively and innate capacities of population increase ( r m ) are -0 0057, 0 0510, 0 0508 , 0 0094 respectively. Under photoperiods of L∶D=14∶10, 12∶12, its net reproduction rates ( R 0) are 23 9628, 12 1562 and innate capacities of population increase ( r m ) are 0 0445, 0 0334. With a photoperiods of L∶D=10∶14, its net reproduction rate ( R -0) is 0, and innate capacity of population increase didn’t exist population would lead to extinction.
