Objective: The objective of the present study was to determine the chemical compounds present in the nests of the mud dauber wasp, Sceliphron caementarium.Methods: Gas chromatography-mass spectrometry analysis of the nest samples was carried out by standard procedures. The resultant compounds were compared with the database of the National Institute Standard and Technology (NIST), WILEY8, FAME.Results: The results of the gas chromatography-mass spectrometry analysis of the concentrated ethanol extract revealed the presence of chemical compounds such as methylene chloride, 1, 1’:3’, 1’’-Terphenyl, 5’-Phenyl, Di N Decylsulfone, Eicosanoic acid, 1, 2-Bis (Trimethylsilyl) Benzene, and Androstane-11, 17-Dione, 3-[(Trimethylsilyl) Oxy]-, 17-[O-(Phenylmethyl) O.Conclusion: The compounds identified were found to have biological properties such as anti-inflammatory, antibacterial, and antifungal, and further study of these isolated compounds may prove their medicinal importance in future.
The beneficial interaction between individuals of two species, commonly referred as mutualism, is recognized as a common and important ecological interaction. Ant-hemipteran mutualisms are wide spread in nature in which homopterans produce honeydew collected by ants, and ants provide protection or other services. Hence the present investigation has been conducted to assess the life cycle of thorn mimic treehopper and to determine the effects of mutualistic strength between Thorn Mimic Treehopper, Leptocentrus taurus (Hemiptera: Membracidae) and the Godzilla ant(Camponotus compressus). It was observed that the secretion of honey dew occurred by tree hopper during evening hours of the day when compared to morning hours. The more the numbers of tickling by the ant, the more honey dew was secreted. There was a significant reduction in the nitrogen and phosphorous level in the host plant after the attack of the host plant by the tree hopper.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
