本文报道了丛生叶螨Tetramorium caespitum（L.）在实验室里用气相色谱-质谱法进行了研究。保留时间较短的色谱峰的质谱图与2，5-二甲基吡嗪相同，而保留时间较长的色谱峰鉴别为3-乙基-2，5-二甲基吡嗪。对10只工蚁毒囊中存在的2种吡嗪类化合物的平均总量进行定量，发现其相当于3.9 ng/ant，其中2，5-二甲基吡嗪约占70%，3-乙基-2，5-二甲基吡嗪约占30%，这些化合物的70：30混合物显示出最高活性，与由单一毒囊制成的试验相比，活性没有显著差异。
The trail pheromone ofTetramorium caespitum(L.) was studied in the laboratory using gas-chromatography-mass spectrometry. The mass spectrum of the peak with the lower retention time was identical to that of 2,5-dimethylpyrazine, while that with the higher retention time was identified as 3-ethyl-2,5-dimethylpyrazine. The average total amount of the 2 pyrazines present in the poison vesicle of 10 workers was quantified and found to be equivalent to 3.9 ng/ant, of which 2,5-dimethylpyrazine accounted for around 70% and 3-ethyl-2,5-dimethylpyrazine for around 30%, and a 70:30 mixture of these compounds showed the highest activity and did not differ significantly in activity when compared with a trail made of a single poison vesicle.
