黑肩绿盲蝽Cyrtorhinus lividipennis(Reuter)取食白背飞虱卵时,其未成熟期的发育速率与温度呈逻辑斯蒂曲线,世代发育起点和有效积温分别为9.83℃,359.05日度。在21—29℃时,世代存活率、Y种群内禀增长力Y2和成虫产卵量Y3粒/雌)较高,高低温区均呈下降趋势,各参数与温度X的关系方程分别为Y1=exp(-3.0031+0,5223X—0.0105X2),Y2=-0.5971+0.0535X—0.0010X2,Y3=exp(-12.0791+1.3869X—0.0278X2)。理论上26℃时周限增长率最大,达1.1044倍/天。以褐飞虱卵、白背飞虱卵、褐飞虱低龄若虫和白背飞虱低龄若虫四种食物作为猎物下,黑肩绿盲蝽成虫的产卵量分别为247.63±74.73、237.25±118.62、196.83±69.08、128.14±81.29粒/雌,其卵孵化率分别为59.83、58.26、44.35、46.96%。结果表明,褐飞虱卵是黑肩绿盲蝽发育、存活和繁殖的适宜食物。
Cyrtorhinus lividipennis (Reuter), a black-shouldered planthopper, developed a logistic curve of immature growth rate and temperature when fed on the eggs of the whitebacked planthopper. The starting point of development and effective accumulated temperature were 9.83 ℃ and 359.05 Japanese. At 21-29 ℃, the survival rate of generations, intrinsic growth potential of Y population Y2 and Y3 grain / females of adult population were higher than those of the control group, and both the high and low temperature regions showed a decreasing trend. The equations of each parameter and temperature X were Y1 = Exp (-3.0031 + 0,5223X-0.0105X2), Y2 = -0.5971 + 0.0535X-0.0010X2, and Y3 = exp (-12.0791 + 1.3869X-0.0278X2). In theory, the maximum growth rate at 26 ℃, up to 1.1044 times / day. With the brown planthopper eggs, white-backed planthopper eggs, young planthopper nymphs and white-backed planthopper young nymphs as the prey, the fecundity of the green-shouldered planthoppers were 247.63 ± 74.73 and 237.25 ± 118.62,196.83 ± 69.08,128.14 ± 81.29 seeds / female, the egg hatching rates were 59.83,58.26,44.35,46.96% respectively. The results showed that the brown planthopper eggs are suitable food for the development, survival and reproduction of Apodemus agrarius.
