摘 要 ：在室内条件下 ,初步研究了寄主挥发物、叶色和表皮毛在美洲斑潜蝇寄主选择中的作用。在嗅觉仪试验中 ,寄主叶片挥发物对美洲斑潜蝇雌成虫没有明显的引诱作用 ;在叶色反应试验中 ,美洲斑潜蝇雌成虫在叶子圆片上停留的时间明显大于在滤纸圆片上停留的时间 (p<0 .0 1) ,其在有叶片区域分布的数量明显多于空白对照 (p <0 .0 1) ;在表皮毛试验中 ,美洲斑潜蝇在无毛叶片上的产卵量明显大于在有毛叶片上的产卵量 (p <0 .0 1)。上述结果表明 ,在对寄主的定向和定位过程中 ,美洲斑潜蝇的视觉起着重要的作用 ,而嗅觉不起作用 ;叶片表皮毛有抑制产卵的作用。

Abstract:The serpentine leafminer, Liriomyza sativae Blanchard, is one of the most serious worldwide pests of a great variety of vegetables and ornamental crops. It was first recorded in China in the Hainan province in 1993. Since then it has spread to the most regions of China, and it has attacked a wide variety of crops causing great economic losses. Previous studies have shown that the leafminer has different preferences for host plants. The mechanism on its host selection, however, is so far unknown. In this pap...
