| 中文摘要: |
| 在室内研究了捕食性天敌食虫齿爪盲蝽成虫对枸杞木虱2龄若虫的捕食作用。结果表明,食虫齿爪盲蝽对枸杞木虱的捕食功能反应符合HollingⅡ型反应,拟合的圆盘方程为Na=0.964 9N/(1+0.313N)。捕食木虱数量随木虱密度增加而增大,但寻找效应随之而降低。食虫齿爪盲蝽对自身密度的功能反应用Watt模型拟合为A=43.089 0P-0.780 5,其捕食作用率与个体间相互干扰作用的关系用Hassell-Varley的干扰反应模型拟合为E=0.5394P-0.378 7,饥饿48 h的食虫齿爪盲蝽的捕食速度与时间段关系的数学模型为V=2.128 1x-1.007 2。 |

| The predation of adult Deraeocoris punctulatus Fallen on second instars of Paratrioza sinica Yang & Li was studied in laboratory.The results showed that the functional response of adults of D.punctulatus to second instars of P.sinica was fitted to Holling Ⅱ-type equation and the equation was Na=0.964 9 N/(1+0.313N).The relationship between the quantity of P.sinica preyed by D.punctulatus and the density of P.sinica could be represented by a negative accelerative curve.The searching efficiency decreased with the increase of P.sinica density.The functional response of adult D.punctulatus to the density of itself could be fitted by the Watt model,A=43.089 0P-0.780 5.The relationship between predation efficiency and individual interference could be fitted by the Hassell and Varley model E=0.539 4P-0.378 7.When they were starved for 48 hours,the relationship between predation rate of adult D.punctulatus and time could be described as V=2.128 1 x-1.007 2. |
