Abstract— Maggot Debridement Therapy (MDT) has been
recognized as one of the effective alternative treatment to
enhance healing and to decrease the mortality associated with
underlying injury. One of the most important procedures in
performing MDT is to use the correct maggot from suitable
species. In this case, maggots from the incorrect species would
consume the live tissue instead of the dead tissue. Hence, this is
highlighted as one of the difficulties in implementing MDT.
Currently the process of identifying flies is done manually by
experts or by using DNA traits. We explored and developed
another procedure to recognize the species using hybrid neuro-
expert technique. The percentage of correctness using standard
back propagation neural network yields 94.4% accuracy. By
adapting the neuro-expert technique, the prototype accuracy is
100%.

I. INTRODUCTION
Maggot Debridement Therapy (MDT) has been
implemented for centuries. The infestation of wounds by
species of fly larvae refers as maggot has been recognized to
debride, enhance healing and decrease the mortality of
underlying injury [1]. In Malaysia the flies that is commonly
used is the Lucilia cuprina species. It is really important for
the researchers to recognize the type of flies that can be used
to ensure the correct maggot to be used in the therapy for the
better treatment of the patient and a fast healing process. The
current method for recognizing the species of flies is by
physical or morphological traits of the adult flies and its
larvae. This method is perform by experts and might consume
time as the examination is manually done by the
entomologists. Other method for species identification of flies
is based on genetic examination or DNA [2]. This system will
be the first application for identifying the flies’ species using
neural-expert system with back-propagation algorithm
(BPNN).
II. MAGGOT DEBRIDEMENT THERAPY
A. Maggot Therapy Practices
Maggot therapy also known as Maggot Debridement
Therapy (MDT) has been used as a traditional way of
cleansing and healing infected wounds. Mayan Indians
wrapped wounds with a dressing made of sun-exposed beef
blood that would pulsate, apparently with maggots [3]. MDT
was successfully and routinely performed by thousands of
physicians until the mid 1940's, when its use was supplanted
by the new antibiotics and surgical techniques that came out of
World War II. Maggot therapy was occasionally used during
the 1970's and 1980's, when antibiotics, surgery, and other
modalities of modern medicine failed.
Recently, maggot therapy has become more popular among
the Malaysian citizen. There are even several specialist
laboratories that produce maggots for clinical and research
purposes. These Maggots are then supplied to clinical centers
worldwide for the treatment of chronic wounds, such as leg
ulcers, pressure sores, diabetic and necrotic ulcers, as well as
infected surgical wounds, burns and trauma injuries [4].
B. The Flies
There are two main species of flies used for MDT; Lucilia
sericata and Lucilia cuprina. However Lucilia cuprina is most
common in Malaysia as Lucilia Sericata is not found in tropics
climate. According to [5] Lucilia cuprina can be easily identify
by the metallic outer appearance and reddish eyes, have a shiny
green or greenish/blue abdomen with bronze/coppery
reflections, body shape is round to oval and their length varies
from 4.5–10 millimeters, have two pairs of wings, and has
bristles on the meron, in addition to the arista, hair on the
terminal antennal segment being plumose, strong dorsal setae,
and black thoracic spiracle. Other than that, the Lucilia cuprina
can also be identified by using the rDNA and looking at the
fine structure of the Lucilia cuprina egg shell.
