The chemical composition of the compounds contained in the tergal spots of Lutzomyia longipalpis was investigated. Four populations of L. longipalpis were examined, originating from: Sobral, Ceará, Brazil (one spot and two spot populations), Santarém, Pará, Brazil (one spot) and Marajó Island, Pará, Brazil (one spot). The tergal spots were dissected out, extracted in hexane and analysed on a gas chromatograph/mass spectrometer. Two compounds were found, identical to compounds found in earlier studies, but there was no correlation between number of tergal spots and type of compound present. It was suggested that the number of tergal spots could not be used as a marker for reproductively isolated populations, and that analysis of the compound present within the spots might be necessary to characterize potentially good vector populations.
对长须罗蛉背板斑点所含化合物的化学成分进行了研究。研究了长须罗蛉的四个种群，分别来自：巴西塞阿拉州索布拉尔（一个斑点种群和两个斑点种群）、巴西帕拉州圣塔伦（一个斑点种群）以及巴西帕拉州马拉若岛（一个斑点种群）。将背板斑点解剖出来，用己烷提取，并在气相色谱仪/质谱仪上进行分析。发现了两种化合物，与早期研究中发现的化合物相同，但背板斑点数量与所含化合物类型之间没有相关性。研究表明，背板斑点数量不能用作生殖隔离种群的标记，可能需要对斑点内所含化合物进行分析，以鉴定潜在的优良病媒种群。
