Electromagnetic field and the Phenomenon of Taxis in Termites (Cryptotermes Brevis)

This paper aimed to verify the influence of the electromagnetic field on the behavior of drywood termites (Cryptotermes brevis) for subsequent use in treating infestations of timber pieces. Different termites were subjected to a maximum electromagnetic field under different temperatures. The results showed that termites are able to sense the presence of an electromagnetic field and respond to its stimuli by means of negative taxis (removal of the field source) and body movements to suit field variations over the area of exposure, as a consequence of Faraday's law of magnetic induction and ferromagnetic hypothesis, which are based on the presence of magnetic particles in the body which act as field sensors. Also, the electromagnetic field caused the termites to present uncontrolled segments and accessory limbs.
