ANALYSES OF CHEMICAL EXTRACTS FROM THE ABDOMINAL GLANDS OF BLACK CARPENTER ANTS (Camponotus .......

Petroleum ether was used to extract chemical molecules from the abdomen glands of black carpenter ants (Camponotus pennsylvanicus), and nineteen chemicals were identified using the gas chromatography-mass spectrometry (GC/MS) approach in conjunction with Fourier transform-infrared spectroscopy (FT-IR). The majority of the substances were (Z)-9-octadecenoic acid (22.28 percent) and hexadecanoic acid (19.12 percent). Other compounds found were decane (1.45%), undecane (2.50%), dodecane (3.67%), 2,9-dimethyldecane (252%), 2,6,11-trimethyldodecane (1.44%), (8E)-8-heptadecene (1.66%), 2,6-dimethylheptadecane (0.90%), 9-heptadecanone (3.04%), hexadecanoic (5.47 percent ). Peaks at 1166.97, 1453.41, 1638.58, 2861.49, 2927.08, and 3425.69 cm-1 were found in the extract's FT-IR analysis, indicating the presence of alcohol, ether, ester, fluorinated ether, alkane, and alkene chemicals. There were 47.87 percent fatty acid, 14.14 percent hydrocarbons, 11.62 percent ester, 11.43 percent alcohol, 5.47 percent siloxane, 4.20 percent alcoholic ester, 3.04 percent ketone, and 2.25 percent fluorinated ester in these compounds. These chemicals were compared to other compounds that have been described as pheromones in other insects, and similarities were found.
