Study on the Biological Activity of Crude Extraction of Castor Bean Shell against Wheat Aphid

WU Xue-ping et al (Henan Institute of Science and Technology,Xinxiang,Henan 453003)  
In this paper,the effect that the crude extraction of castor bean shell on wheat aphid was studied.The regressive equation of the crude extraction against wheat aphid was y=1.342?7x+1.649?9,LC_(50)=312.64?mg/ml,r=0.972~(**) after 48?h,and the regressive equation of the crude extraction against wheat aphid was y=2.629?4x+0.376?9,LC_(50)=57.31?mg/ml, r=0.942?9~* after 72?h.
