RFID Entomology

An area that seems in its infancy at the moment in Entomology is the use of Radio Frequency Identification [RFID] tagging insects.  RFID is, “a generic term for technologies that use radio waves to automatically identify people or objects. There are several methods of identification, but the most common is to store a serial number that identifies a person or object, and perhaps other information, on a microchip that is attached to an antenna (the chip and the antenna together are called an RFID transponder or an RFID tag). The antenna enables the chip to transmit the identification information to a reader. The reader converts the radio waves reflected back from the RFID tag into digital information that can then be passed on to computers that can make use of it”[1].

For entomology this could prove a valuable research into insect dispersal studies, migration, colony relationships, and added authority to the science of forensic entomology.  There are already studies underway.  Prof. N. Franks of the University of Bristol, UK is using RFID to study the division of labour of ant colonies[2].  The Zoological Society of London have successfully used FRID to monitor males and female paper wasps[3].

I suppose the question is could this be used further.  Perhaps we could RFID tag bees in the USA to solve the mystery of Colony Collapse Disorder[4].

There is no worries about the size of the RFID tag coming in the way of the research news is that the RFID tags are getting smaller[5].  There is also a US patent on using RFID technology with insects[6].
