摘    要:研究结果表明:①南美斑潜蝇为害大棚芹菜和芸豆,其虫道面积和产量呈负相关,与产量损失率呈正相关;②曲线回归方程为:Y(大棚芹菜产量)=4.233/(1+0.2669e0.0281X),Y(大棚芸豆产量)=500950.702/(1+39262,76541e^0.0103X),Y(大棚芹菜产量损失率)=68.075/(1+23.1517e^-0.071X),Y(大棚芹菜产量损失率)=71.765/(1+4.26245e^-0.0305X);③经济阈值模型为:X(大棚芹菜)=14.0845ln[23.1575L/(68.075-L)],X(大棚芸豆)=27.3973ln[4.26245L/(71.765-l)]。

Abstract:The study indicated that: (1) The yield ratio of kidney bean and celery in greenhouse were 3.60%-65.0% and 12.27%-61.12% respectively when the leaf area damaged by Liriomyza huidobrensis Blanchard was between 5% and 85%. (2)The correlation between the leaf area damaged and yield was negative, but positive with the yield loss ratio. The curvillinear regression equation were: Y(celery yield)= 4.223/(1+0.2669e 0.0281X ); Y(kidney bean yield)=500950.702/(1+39262.76541e 0.0103X ); Y(celery yield loss ratio )= 68.075/(1+ 23.1517 e -0.071X ); Y(kidney bean yield loss ratio)= 71.765/(1+4.26245e -0.0305X ). (3) the economic threshold model were: X(celery)= 14.0845ln[ 23.1575 L/(68.075-L)]; X(kidney bean)=27.3973ln[ 4.26245 L/(71.765-L)].
Keywords:Liriomyza huidobrensis Blanchard   celery   kidney bean   yield loss   economic threshold
