ABSTRACT
The study was conducted to identify the different families of Diptera; to record
the distribution of Diptera; and to determine which among the families has the most
abundant in species on the different vegetations. Collecting was done through sampling
of the different traps from May to September 2008 at Bektey, Puguis, La Trinidad,
Benguet.
The collected specimens at BSU Nature Park yielded a total of 50 species
belonging to 31 families of Diptera.
The distributions of Diptera in both vegetations were 32 species, 11 species from
the mixed forest and 7 species in coffee under pine tree.
In both vegetations, the families with the most abundant in species were:
Calliphoridae, Anthomyiidae, Agromyzidae, Cecidomyiidae, Culicidae, Drosophilidae,
Muscidae, Stratomyiidae, Heleomyzidae, and
Tachinidae.

INTRODUCTION
Order Diptera or true Flies is composed of 99 families. It has so many species
with so many different styles thus it is difficult to generalize. Typical adult have a single
pair of membranous wings, rarely scaled. The wings have few cross veins and moderate
number of veins. Only a pair of slender knobbed balancing organ called halters represents
the hind wings. Mouthparts are of various types; in some groups they are modified for
piercing and sucking, in other groups for rasping and lapping. The body form is diverse.
In a few groups, the adults are completely apterous. The eyes are usually large and their
antennae vary from three to forty segments. These are holometabolous insects with
legless larvae, usually either with distinct mandibulate head or with an external
sclerotized skeleton attached to a pair of hook-like mandibles. The pupa is either free or
formed with the skin of the third instar larvae.
As a group, fly larvae are moisture loving, the great majority living in water,
rotting flesh, inside the bodies of other animals, in decaying fruits or other moist organic
materials, or inside living plant tissue. A few live in relatively dry soil or more about
exposed to the air.
Flies has the largest number of pest and one of the best vector pathogen that may
harm and kill animals, high volume crops that may lead to low cost value of the livestock.
And usually have low returns to the farmers investments, low quality vegetables, fruits
and cut flowers because of the diseases of the pathogen that have been introduced or of
the insects daily activities, completing its lifecycles in or out of the host plant resulting to
its defoliation and all the related parts of the crops will be affected by flies, considered
nuisance pest (Professional Pest Control, 2004), domestic of filth flies (Lyon, 2004).

These best known to transmit diseases like conjunctivitis, poliomyelitis, typhoid fever,
tuberculosis, anthrax, leprosy, cholera, diarrhea, and dysentery (Lyon, 2004). Dura pest
control (2004) added hepatitis, diphtheria, scarlet fever, yaws, pink eye, tapeworm and
hookworm. Bloodsucker insects are directly responsible for the transmission of malaria,
filariasis, leishmaniasis, trympanosomiasis (sleeping sickness) and a wide rage of
arbiviruses including yellow fever, dengue, and various encephalatides. Most of the
vector species are the mosquitoes.
At present sustaining biodiversity of plants and animals is now becoming a
concern worldwide. This is brought about by the conversion of forested areas into
agricultural areas with monocrops, building of houses and industrial areas with toxic
waste and many more. As a result, incidences of pest outbreak on crops occur and even
human diseases. With the realization that species and habitats as well as fertile lands are
being lost, the International Union for Conversion Nature (IUCN) was established to help
and encourage nations to conserve wildlife and natural resources.
Insect fauna in Benguet State University (BSU) Nature Park need to be studied
and identified before they become instinct and need to be preserved as a basis for the next
generation.
The results of the study may provide a benchmark data on the students who
wishes to study more on the different families under Diptera and a basis or guide to
anyone whose studies are related to Insect Systematic. These also provide information
regarding families of Diptera inhabiting at the BSU Nature Park.
The study aims to come up with a general idea on Diptera inhabiting on selected
vegetations at BSU Nature Park. Specifically, it aims to: identify the different families of
Diptera Inhabiting Selected Vegetations at BSU Nature Park / Esther C. Tonged. 2009

Diptera; and to record the distribution of Diptera and which among the families has the
most abundant in species on the different vegetations.
The study was conducted at BSU Nature Park, Bektey, Puguis, La Trinidad,
Benguet from May to September 2008.

REVIEW OF LITERATURE
Characteristics of Flies
The major morphological feature, which distinguishes flies from other insects, is
their reduced hind wings, termed halteres. The halteres are small, club-like structures that
function as balancing organs during flight. Thus, adult flies have only one pair of
functional wing, hence their scientific name- Diptera (di-two, pteron-wing). A few other
groups of insects have also convergent, attained a similar two-winged form such as
coccids (Hemiptera-
Sternorrhyncha). A few flies have lost their wings (and halteres)
altogether (CSIRO, 1990).
The mouthparts of flies are also characteristically suctorial and many have large
fleshy pads with drainage canals termed pseudo tracheae for efficient liquid uptake.
Habitat
Larvae occur in aquatic, semi aquatic and moist terrestrial environments, as
endoparasites of other animals or as miners within plant tissues, but because their cuticle
is soft and susceptible desiccation, only a few live in dry environments.
Adults
are
usually
terrestrial, active in the day time, and almost free-living, the
exception being the ectoparasitic adults of the louse flies (family
Hippoboscidae,
Streblidae and
Nycteribiidae) (Borror, 1976).
Feeding Ecology and Diet
Larvae are pythopagous (feeding on leaves, fruits or roots of plants), filter organic
matter, or are spacers of algae, predators, parasitoids and sarcophagus feeders or decating
organic matter including vegetables, dead animals or dung. Endoparasitic larvae include
Diptera Inhabiting Selected Vegetations at BSU Nature Park / Esther C. Tonged. 2009
5
those in the family
Tachinidae, which parasitise other insects, particularly spiders and
centipedes; those in family
Pipunculidae, which parasitize the larvae of cicadas and leaf
hoppers; and some species of bee flies (family
Bombyliidae), which develop in the eggs
or larvae of bees and wasps, other flies, beetles and butterflies.
Adults typically consume liquid food such as nectar and other plant exudates or
decomposing organic matter, or they prey on other insect or mollusk; adult of some
species for all little or nothing at all. Females of some groups may take blood meals from
vertebrates (Sci-tech Encyclopedia, 2005).
Characters Used in the Identification of Diptera
The principal characters used in the identification of Diptera are those of the
antenna, legs, wing venation, and chaetotaxy (the arrangement of the bristles, chiefly on
the head and thorax). Occasionally various other characters are used such as the presence
or absence of certain sutures, the shape of the head or abdomen, the form of the mouth
parts, and the presence or absence of the ocelli.
Description of Families of the Insect Order
Agromyzidae. This are small to minute flies and usually blackish or yellowish in
color. The larvae are leaf miners and the adults occur almost everywhere. Most species
are mare easily recognized by their mines than by the insects themselves. There
mesopleural bristles are present; tibia without preapical dorsal bristles, female abdominal
segments 7 enlarged, entirely esclerotized (Borror, 1976).

Anisopodidae. These are usually found in moist places on foliage and larvae live
near decaying organic matter and fermenting sap. Two branches of their wings (Rs) not
connected were not connected by the cross vein and antennae with 12 16 segments.
Asilidae. Also called the robber flies. They have the top of the head hollowed out
between the eye, the face more or less bared, and they have a stout thorax, with long
strong legs. Most of them were elongate, with the abdomen tapering, but some are stout
bodied and very hairy.
Anthomyiidae. The member of this group are very similar to the Muscidae but
they differ in having the anal vein (Cu2+2A) reaching the wing margin, at least as a fold;
most of them are dark bodied and rather slender and some are quite hairy.
Bibionidae. The members of this group are small to medium- sized, usually
colored, stout-bodied flies with rather short abdomen at rest; the wings of midges are
usually more elongate, and are held roof-like over the abdomen at rest.
Calliphoridae. Most blowflies are about the size of a housefly or a little larger,
and many are metallic blue or green. They have the aristae on the antennae plumose to
the tip. The hind most posthumeral bristle is usually more laterally located than is the
presutural bristle.
Canaceidae. The canaceids are small flies that resemble the Ephydrids in
appearance and habits, but have only a single break on the Costa, they have an anal cell,
and the ocellular triangle is quite large.
Cecidomyiidae. These are minute delicate flies with long legs and usually
relatively long antennae and with reduced wind venation. Their eyes are meeting above
the antennae and with two three ocelli.

color with black spots on the abdomen. R5 cell not narrowed apically; legs not usually
long and slender; length usually less than 7 mm and post verticals converging or absent.
Clusiidae. The clusiids are small, 3-4 mm in length and the body color vary from
pale yellow to black; some species have the thorax black dorsally and yellowish laterally.
Culicidae. This family was recognized by the characteristic wing venation, the
scale along the wing veins and the long proboscis extending clypeus. The prominent
mouth brush of setae present on either side of labrum, antennae well separated and with
short apical setae.
Dolichopodidae. These are small to minute flies that are usually metallic in color,
greenish, bluish or coppery. They lack of frontal sub suture and have a characteristic
wing venation: the r-m cross vein is very short or absent and is located to the basal forth
of the wing, and there is often swelling of Rs where it forks.
Drosophilidae. They are small flies or pomace flies. They are 3-4 mm in length
and usually yellowish in color, and are generally found around decaying vegetations and
fruits. They have reclinate fronto-orbital bristle near the eye.
Empididae. Small to minute flies; found in moist places; with large thorax and
long tapering abdomen, the male genetalia are terminal and often are rather conspicuous.
The r-m cross vein located beyond the basal fourth of wing; fork of Rs not swollen and
body are not metallic.
Gasterophilidae. These flies are somewhat similar to honey bees in general
appearance. Adults have vestigial mouthparts and all species are brown in color and it has
patterned wings.

Heleomyzidae. These flies are medium size and lack femoral bristles and has R1
ending beyond the middle of the wing. In profile, the third antennal segment appears
rounded, and the face is slightly concave below the antennae.
Lauxaniidae. They are small, relatively robust flies, rarely over 6 mm in length,
and some have patterned wings; they vary considerably in color. The complete subcosta,
no oral vibrissae, and the post verticals converging can distinguish them.
Lonchaidae. The lonchaeids are small, shinning blackish flies, with the abdomen
in the dorsal view oval and somewhat pointed apically; they occur chiefly in moist or
shady places.

recognized by the characteristic hind tarsi. Hind base tarsus much swollen, or shortened
or compressed; vibrissae distinct; fore leg not raptorial; tarsal claws not normal.

are brightly colored and wasp like in appearance. Their branches of the radius are rather
heavy and are crowded together toward the costal margin of the wing.
Sarcophagidae. Flesh flies are very similar to some blowflies, but are generally
blackish with gray thoracic stripes (never metallic). The abdomen with pearly maculae or
dark round maculae. Body densely plumose and with three or more notopleural bristle
present.

quite a bit in appearance but can recognize by the spurious vein in the wing between the
radius and the media. Many are brightly colored and resembles as bees.
Tachinidae. Subscutellum strongly developed, stout bodies, strongly bristled and
drab in coloration. They range in size from small species about half as big as a housefly.
Family Tephritidae. The members of this group are small to medium sized that
have usually spotted or branded wings. They can be recognized by the structure of the
subcosta, which bends forward at almost a right angle and at fades out; in most species
the anal cell has an acute distal projection posteriorly.
Basic Control Strategies of Flies
The basic strategy for control flies on diseases is to reduce the amount of potential
breeding locations. The primary fly breeding locations are in fresh manure, bedding
materials such as straw in calving areas around hatches and decaying plant materials such
as silage or hay. Composting grass clippings are also suitable breeding locations for some
flies. More expensive steps for fly control may include biological control and
insecticides (Kirk, 2007).

MATERIALS AND METHODS
Materials
The materials used in the study were the following: insect net, killing jar,
microwavable plastic containers, forceps, syringe yellow plastic plate, cellophanes,
grease, plastic containers, banana peelings, pork, microscope, lamp, digital camera, pins,
syringe, ruler, paper envelope, vials, mothballs, 70% ethyl alcohol, forceps, pen and
notebook and other references like Entomology books.
Site of Collection
The sites of collection were the selected vegetations found at the BSU (Benguet
State University) Nature Park, which is about three kilometers away from the BSU main
campus. The two vegetations are the mixed forest vegetations (Figure 1) and the coffee
under pine tree (Figure 2). The collection site has a sloping area and non-probability
sampling was used.

Time of Collection
Collecting of Diptera were done twice a month for the months of May to
September 2008.
Four methods of collecting techniques were used – the yellow plastic plate
(Figure 3), carrion trap (Figure 4), fruit trap (Figure 5), and the natural insect trap (Figure
6).

Trapping of Diptera
Yellow plastic plate. In each sites, 10 yellow plastic plates were set. This trap was
made up of plastic plate with a diameter of 30 centimeters, cellophanes and grease. The
grease was spread on the cellophanes with paper plastic plate inside. The trap was hanged
on the branches of trees with a height of four feet above the ground. Settings of this trap
were done three days before collecting. A forceps was used in gathering the trapped flies
and placed on vials with 70 % ethyl alcohol.
Fruit trap. This is a plastic container with pieces of banana peelings inside and
with a stand of two feet above the ground. Fine holes were made at the bottom of the
container to provide drainage for the rainwater. Five fruit traps were set on each site.
Setting of this trap was done three days before collecting the specimens. Insect net was
used in collecting the flies. The flies were put on killing jar and placed on vials with 70 %
ethyl alcohol.
Carrion trap. One kilo of pork was bought from the market and was divided into
four pieces. The pork was place inside a container with a stand of two feet above the
ground. Two carrion traps were set on each sites and setting was done three days before
collecting the specimens. Insect net were used in collecting the flies and placed on 70%
ethyl alcohol.
Natural insect trap. The natural trap used was the trap used by Sumingwa, 2004.
1. Fermented plant juice. Two kilo of banana trunk (cardava variety) were finely
chopped and mixed with one kilo of crude sugar and contained in a clay jar. The jar was
covered and left to stand for a day to let the contents settle at the bottom. The following
Diptera Inhabiting Selected Vegetations at BSU Nature Park / Esther C. Tonged. 2009
14
day, the jar was stored in a cool and a shaded place for fermentation for seven days. The
fermented juice was extracted and transferred to a container.
2. Decoction of vinegar. One gallon of pure white coconut vinegar was mixed
with half kilo grounded crude sugar. The mixture was heated until it reached its boiling
point. The boiled mixture was set aside to cool and was used in preparing the attractant.
3. Preparation of mixture. 350 millimeters of concentrated plant juice were
measured and added to the cooled decocted vinegar. The mixture was set aside and was
set for testing.
4. Setting of trap. The traps were made up of pet bottles containing one and one
half inch thick natural trap. Two opposite sides of the bottles were opened as the entrance
of the flies attracted. Five traps were set on each sites and setting were done three days
before collecting the specimens. Forceps was used in picking the flies and they were
placed in 70 % ethyl alcohol.
Preservation of Flies
Immediately after the flies’ dies inside the killing jar it was placed in a paper
envelope. This serves as the temporary storage of flies collected that cannot be fixed
immediately. The flies were placed in a vial with 70% ethyl alcohol.
Identification of Flies
The different families of Diptera were collected were seen under a stereo zoom
microscope for proper identification at MPRH building. Collected specimens were
classified according to their family and species. The Insect of Australia book and through
Diptera Inhabiting Selected Vegetations at BSU Nature Park / Esther C. Tonged. 2009

Distribution of Diptera on the Different Vegetations
Table 1 shows the distribution of Diptera on the mixed forest and Coffee under
pine tree vegetations. Diptera were widely distributed at the mixed forest than in coffee
under pine tree with 44 and 38 species, respectively.
Diptera were widely distributed at the mixed forest vegetation because of the
presence of different plants that serves as their host and it can support the foods of
insects, while in coffee under pine tree that has limited plants presents. Important note
regarding species distribution was mentioned by Clark, et al. (1967) who emphasized that
in nature, insect’s species exist and evolve as components of communities of plant and
animals in particular habits. Some insect species, including many predators, exist as
member of a number of a community. All insects have a limited distribution range; and
characteristically, insect numbers fluctuate to a greater or lesser extent both in time and in
space.

Families of Diptera which has the most abundant
species in the vegetations at the BSU Nature Park
Family
Calliphoridae has the most abundant in species collected in both
vegetations with four species each. Under mixed forest, three species of family
Anthomyiidae,
Culicidae, Drosophilidae, and
Stratomyiidae were collected and then the
family
Agromyzidae, Anisopodidae,
Cecidomyiiade, Muscidae and
Tachinidae has two
species each. While on the other hand, family
Cilicidae has three species collected and
two species of family
Anthomyiidae,
Agromyzidae, Cecidomyiidae, Muscidae,
Stratomyiidae and
Helcomyzidae at coffee under pine tree.
Meanwhile, Baucas (2007) mentioned that one of the top highest families at the
park were the order Diptera with 24 families collected and family
Drosophilidae had the
highest family with a population of 16.

SUMMARY, CONCLUSION AND RECOMMENDATION
Summary
The study was conducted mainly to identify the Diptera inhabiting different
Vegetations at BSU Nature Park; to record the distribution of Diptera; and to determine
which among the families has the most abundant in species at the park. It was done by
collecting through yellow plastic plate trap, carrion trap, fruit trap and natural insect trap,
for the month of May to December 2008. Individual species collected was identified
according to their families and species.
There were 50 species of Diptera collected belonging to 31 families. The 31
families were the
Agromyzidae,
Anisopodidae, Anthomyiidae, Asilidae, Bibionodae,
Calliphoridae, Canacidae, Cecidomyiidae, chamaemyiidae, Clusiidae, Culicidae,
Dolichophilidae, Drosophilidae, Empididae, Gastrerophilidae, Helcomyzidae,
Lauxaniidae, Lonchaidae, Micropezidae, Milichiidae, Muscidae, Neriidae, Phoridae,
Psychodidae, Sacrophagidae, Sepsidae, Sphaeroceridae, Stratomyiidae, Syrphidae,
Tachinidae and
Tephritidae.
Forty-four species of Diptera were widely distributed at mixed forest while 38
species at coffee under pine tree.
Like wise, family
Calliphoridae has the most abundant number of species
collected from the different vegetations.
Conclusion
It is therefore concluded that some species are widely distributed through out the
area which some are solely confined in one vegetation, which clearly implies that
Diptera Inhabiting Selected Vegetations at BSU Nature Park / Esther C. Tonged. 2009
41
arthropods prefers a place to live in or the kind of habitat determines the species that can
live on it.
Recommendation
It is therefore recommended that more study on this insect should be done to
determine their significance to animals and plants.
