Why Are Insects So Successful At Being Pests

Insects comprise about three-quarters of all the different species of animal that live on earth. While there exists great diversity in form and function among insects as a group, a number of general characteristics may contribute to their success.

 Size

 Insects range in size from microscopic to those which are as large as the smaller mammals. Overall, they are relatively small compared to most other animal life forms, and this can be regarded as a distinct advantage best appreciated by considering the enormous range of habitats available. Lice can live and feed for their entire lifespan on just one part of the host animal. Hundreds of flies can develop from the droppings of one large grazing animal. Thousands of cockroaches can find living space in the cracks and crevices of a kitchen, along with enough food and water to sustain an enormous population. One disadvantage of such a small size in animals is that, because of the ratio of body surface area to body volume, moisture is lost more easily than in larger animals.. Conservation of moisture is critically important to any life form, and insects have accommodated to this problem by developing, in most cases, a remarkable, protective body covering.

 Rapid reproduction

 Insects produce huge numbers of offspring, which often develop quickly into reproductive mature adults. Termites can fill huge colonies in no time and can spread in the entire wood area within a few months. Environment friendly solution hence is important where house have a lot of wood work done. By and large, most female insects lay large numbers of eggs in any location that is likely to facilitate the feeding of the young insects after they hatch. As well, most insects undergo a relatively rapid development and life cycle. These two factors together provide a key to the doorway of adaptability.

 Adaptability

When life forms reproduce at a rapid rate in large numbers, they create a vast genetic pool. A large population has a potential genetic variability so that selection can operate to specialize and adapt to a vast range of environmental conditions. This ability to adapt to different conditions is perhaps their greatest asset in survival over the eons and now in their competition with humans for their food and shelter. A short life cycle means they can keep up with change and not become extinct because they couldn’t or didn’t.

 Over millions of years of exploiting different food sources, insects have evolved a diverse range of mouthpart types for different diets. The more primitive chewing mouthparts, such as on cockroaches and grasshoppers, have in some insects been modifies through long periods of evolution into equipment that can pierce plant or animal tissue to suck up the blood or juices. This evolution is very evident in experience Singapore pest control and fleas.

 Equipped with such weapons on hand, insects have become highly successful in cohabiting with the humans and becoming the pests that they are.
