Dipteran insects and their positive role in environment.
The word Diptera is derived from Greek di meaning two and ptera meaning wings.Though these
insects are known to have two wing they efficiently use only there for flight and the hind wings
being reduced to balanced organs called \"Halterers\".
The order diptera includes a large number of species most of them are known for their ability to
cause diseases in human beings but they are of considerable ecological and human
importance.They are known to cause dreadful diseases like malaria,dengue, yellow fever by
acting as vectors but their beneficial role in ecosystem cannot be ignored.
Some of the positive aspects of the order can be listed as follows:
1. We know that pollination is an essential mechanism for fruit production and we are aware that
bees are important pollinators .Dipterans are the second largest pollinators after the
hymenopterans.In fact they are said to be the earliest pollinating agents. Many crop plants are
dependent on these insect for pollination without which the fruit bearing process is not
completed.
The chocolate which we enjoy would have not been there had there been no flies. It is a known
fact that the chocolate plant Theobroma cocoa produces very small flowers and are self
incompatable for various reasons very small midges of the families Ceratopogonidae and
Cecidomyiidae pollinate the small white flowers emerging from the stems. so next time we curse
a fly remember that we will go without chocolate if we eradicate them.
2. The study of genetics has made many things impossible possible now , we should not forget
the contribution of our fruit fly here . Most of the genetic studies are based upon the experiments
conducted on fruit flies,because of there smaller genome and easy to rear they serve as excellent
genetic model organisms.
3. They play an important role at various trophic level both as consumers and as prey. In many
aquatic ecosystems they form the main food source for birds and fishes.As herbivores in
wetlands, flies can be very beneficial in controlling potential eutrophication.Many of the aquatic
flies are known to reduce algal proliferation, despite very high algal productivity.
4. They form a dominant taxa in temperate ecosystems.
5.Maggots are reared and are used as fishing baits.
6. Some of the maggots which selectvely feed on the necrotic tissue are used in medicine in
debraidment to clear wounds.
7.Some members belonging to the families Muscidae or the Sphaeroceridae are detritivores,
meaning they feed on decaying material. . These are beneficial in that they speed up nutrient
cycling and thus lead to a richer soil (indirectly).Larve of some of the diptran insects are known
to act as excellent scavengers , decomposers.
