通过硅胶色谱法分离了佛罗里达州两个热带火蚁种群(深色和红色)工蚁的角质层碳氢化合物 (CHC),并通过 GC/MS 分析进行了鉴定。深色形式和红色形式都产生相似的 CHC,碳链长度范围为 17 至 35。然而,两种颜色形式之间这些 CHC 的相对百分比始终不同。深色形式中最大的 CHC 成分是二十三烷,红色形式中最大的 CHC 成分是 (Z)-9-二十三碳烯。百分比组成存在几个显着差异。例如,深色形式的特点是二十三烯:二十三烷比率较低(约 0.25),而红色形式的该比率> 2.5。三二十碳烯:二十三烷的比例可用作诊断生物标志物来界定深色和红色形式。聚类分析表明,深色型菌落的CHC模式与红色型菌落的CHC模式完全分离。这种黑暗形态和红色形态的工蚁之间的社会行为差异,如同巢伴侣识别和一夫多妻制,有待进一步调查。
The cuticular hydrocarbons (CHCs) from hexane rinses of workers from two Florida populations (dark and red forms) of the tropical fire ant, Solenopsis geminata, were separated by silica gel chromatography and identified by GC/MS analysis. Both the dark form and the red form produce similar CHCs with carbon chain lengths ranging from 17 to 35. However, the relative percentages of these CHCs were consistently different between the two color forms. The largest CHC component in the dark form is tricosane, and (Z)‐9‐tricosene for the red form. There were several significant differences in percent composition. For example, the dark form was characterized by a low tricosene:tricosane ratio (ca. 0.25), whereas this ratio was > 2.5 for the red form. The ratio of tricosene:tricosane can be used as a diagnostic biomarker to delimit the dark and red forms. Cluster analysis showed that the CHCs patterns of dark form colonies are completely separated from the CHC pattern of red form colonies. Differences in social behaviors like nestmate recognition and polygyny between workers from this dark form and the red form await further investigation.
