稻虱缨小蜂Anagrus nilaparvatae对寄主白背飞虱Sogatella furcifera卵密度的功能反应为负加速曲线,其方程为:N_a=N{1-exp[-0.2121/(1+0.02935)]},其中N为寄主密度,N_a为日每雌蜂寄生寄主数。瞬时攻击率a为1.2121/天,处理时间Th为0.0242天,理论上每雌蜂日最高寄生卵数为41.3粒。第1天产出卵率(y)随寄主密度(N)变化方程为y=0.0342N~(0.7223)。搜寻效应a与寄生蜂自身密度P的关系方程为a=1.0913P(-1.1717),寄生蜂个体间存在明显的相互干扰效应。
The functional response of Anagrus nilaparvatae to the density of host whitebacked planthopper Sogatella furcifera eggs is negatively accelerated, with the equation: N_a = N {1-exp [-0.2121 / (1 + 0.02935)]}, where N For host density, N_a is the number of parasitized hosts per female per day. The instantaneous attack rate a is 1.2121 / day, the processing time Th is 0.0242 days, theoretically the maximum number of parasitic eggs per female was 41.3. The equation of egg yield (y) on day 1 with host density (N) was y = 0.0342N ~ (0.7223). The relationship between the searching effect a and the parasitic bee’s own density P is a = 1.0913P (-1.1717). There is obvious mutual interference between the parasitoids.
