Do Termites Produce Naphthalene?
WouterNaphthalene is a hydrocarbon found in some wood and termite colonies. However, it is a very toxic substance. It is used by termites to defend themselves against natural enemies. They cement wood together with excrement and also use naphthalene in their nests.
Researchers at Louisiana State University Agricultural Center in Baton Rouge, Louisiana, have developed a new method to detect termite activity. This invention could save homeowners millions of dollars each year. The development of this invention was partially funded by the United States Department of Agriculture.
The new system uses a plastic cylinder that has two chambers. The first chamber is filled with a food source that attracts termites to enter. The second chamber has a plug that keeps termites out. Using a unique gas, researchers have developed a way to identify termite activity.
This invention is based on the discovery that naphthalene can be produced by termites. The presence of this substance can be detected by gas chromatography-mass spectrometry. It has been identified in a number of colony sites in the United States, including Florida and Louisiana.
The compound is a precursor in the production of phthalic anhydride. In addition to being a repellent, it can inhibit fungal growth. These properties make it ideal for use as a termite nest fumigant.
A naphthalene derivative called 2′-acetonaphthone has been shown to be highly effective as a termite repellent. In a recent study, the chemical reduced tunneling and feeding activities in termites. It also inhibited molting.
