摘要: 黑肩绿盲蝽Cyrforhinus livisipennis(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y1,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=cxp(-3.0031+0.5223X-0.0105X2), Y2=-0.5971+0.0535X-0.0010X2,Y3=exp(-12.0791十1.3869X-0.0278X2 理论上26℃时周限增长率又最大,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±94.73、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。

Abstract: evelopmental rate, survival and age-specific fecundity of Cyrtorhinus lividipennis (REUTER), an important egg predator of the rice planthoppers, fed on eggs of white-backed planthopper (Sogatella furcifera Horvath), were determinedunder various constant temperatures from 17℃-33℃ and with different food. The developmental rate curve of this predator is in the shape of a sigmoid. The deve lopmental threshold and thermal constant were estimated to be 9.83℃ and 359.05day-degree, respectively. The generation survival (Y1), the intrinsic rate of capacity of increase(Y2) ,nd the total eggs laid per female (Y1)were higher at 21℃-29℃, which can be described by following equations, Y1= exp(-3.0031+0.5223X-0.0105X2), Y2= -0.5971+0.0535X-0.0010X2,and Y3= exp(-12.0791+l.3869X-0.0278X2), whereX is the temperature in ℃. The optimum temperature for the population growth is 26.00℃ with a maximum finite rate of increase of 1.1044.On average, the number of eggs laid per female are 247.63±74.73, 237.25±18.62, 196.83±69.08 and 128.14±81.29, when fed with BPH egg, WBPH egg, BPHyoung nymph and WBPH young nymph, respectively. However, the developmental rate and longevity are not significantly affected by these prey. Egg hatchability is 59.83, 58.26, 44.35, and 46.96, respectively. Therefore, BPH egg is the best food of Cyrtorhinus lividipennis.
