摘　　要：对马缨丹(Lantanacamara)、黄花马缨丹(Lantanacamaracv.‘Flava’)和紫花马缨丹(Lantanamontevidensis)花序上中华微刺盲蝽(Campylommachinensis)的密度调查结果表明,中华微刺盲蝽在3种颜色马缨丹花序上的分布与花序颜色无关(偏相关系数为0.240,P=0.147,n=40),但与花序中的黄胸蓟马数量和花序中小花数的偏相关系数分别为0.512(P<0.0001,n=40)和0.451(P<0.0001,n=40),达到极显著水平.中华微刺盲蝽对不同颜色粘卡的试验也表明,该盲蝽寻找植物寄主时,视觉刺激并不起作用.四臂嗅觉仪的试验结果表明,中华微刺盲蝽对马缨丹的气味有强烈的趋向作用.采用固相微萃取和气相质谱联用技术分析表明,3种马缨丹花序的挥发物有7种相同的化学成分.Investigations were carried out on the orientation behavior of adult Campylomma chinensis Schuh (Hemiptera:Miridae) toward plant hosts Lantana camara,L.camara cv.‘Flava',and L.montevidensis (Spreng.) Briq.(Verbanaceae).Surveys on three Lantana plants showed that the distribution of C.chinensis in inflorescences was not related to floral color (partial correlation coefficient was 0.240,P=0.147,n=40),but to the number of Thrips hawiiensis Morgan (partial correlation coefficient was 0.512,P<0.0001,n=40) and the flowers per inflorescence (partial correlation coefficient was 0.451,P<0.0001,n=40).In a colour preference experiment,no adult C.chinensis attracted to six different colour plates in longan field.The testing results of four-armed olfactometer indicated that adult C.chinensis had a significantly higher preference for L.camara.It was concluded that olfactory stimuli played an important role in searching for plant hosts of C.chinensis.Solid phase micro-extraction (SPME) and GC-MS were employed to analyze the volatiles compounds of Lantana,and seven same chemical constituents were detected from the volatiles of three Lantana plants inflorescence.
