【摘要】 本文研究了生境、温度等因素对芬兰真绥螨捕食功能的影响 ,结果表明芬兰真绥螨幼、若、成螨对针叶小爪螨幼、若、成螨的功能反应均为HollingⅡ型 ,生境大小及温度变化均能引起功能参数值的变化 ,但不改变反应类型。芬兰真绥螨雌成螨对针叶小爪螨的控制能力最强 ,对若螨捕食量最大。功能反应参数瞬时搜寻率 (a)与温度 (T)的关系式为a =- 0 .0 0 14T2 +0 .0 82 3T - 0 .7848,r2 =0 .93,处置时间 (Th)与温度 (T)的关系式为Th =- 0 .0 0 0 0 3T3 +0 .0 0 2 3T2 - 0 .0 5 98T+0 .5 35 6 ,r2 =0 .95 98。干扰反应方程拟合为E =0 .2 0 12P- 0 .80 84。更多还原

【Abstract】 By studying the effects of stages ?life environment and temperature on the predation of Euseius finlandicus,this paper concludes that the predatory response model of Euseius finlandicus(include larvae ?nymphs and adults)preying on Oligonychus ununguis(include larvae ?nymphs and adults)are found all belonging to HollingⅡ?The rang of life environment and temperature can affect the parameters,but cannot change the predatory reaction model?The equation of the instantaneous rate of discovery(a)and temperature is a= -0.0014T 2 + 0.0823T - 0.7848,r 2=0.93,and that of the handling time (Th)and temperature is Th= -0.00003T 3 + 0.0023T 2 - 0.0598T + 0.5356,r 2=0.9598?The functional response to predator density is E=0.2012P -0.8084?更多还原
