Entomology: The Study of Insects and their Relatives Insects and their terrestrial relatives belong to the phylum called Arthropoda and have inhabited the earth for an extensive time. Paleontologists show that the earliest fossils, most primitive forms of arthropods date back to the Devonian Period over 350 million years ago (Henning 1981). By the Age of Dinosaurs, 300 million years ago, insects were abundant in number and diversity. Like the dinosaurs, some pre-historic forms of insects were enormous: the dragonfly Meganeuropsis had a wing span of 35 inches, and the giant Mesozoic relatives of the scorpions, the eurypterids, measured over 6 feet in length (Borror and others 1992).

The â€Å"guasanos de Maguey† larvae of the giant skippers collected from the fleshy leaves of maguey plants eaten in Mexico (Borror and others 1992). In the United States few people eat insects, knowingly. Those eaten are usually sold at gourmet shops. In Western society insect as a food source is ostracized however some including, honey, which is regurgitated by bees, and relatives of insects, such as lobsters, grayfish, shrimp, and crabs, are considered delicacies. Our society has considered eating bugs, â€Å"strictly for the birds.† In fact, presence of bugs in our food source is considered contamination and unsanitary. Although some bugs are highly lethal, not all should be cause for alarm when found on your plate- consider them as a source of extra protein and essential lipids (Gorham 1976). For centuries insects or their products have played a role in therapy. For instance, the jaws of soldier ants have been as sutures for skin wounds, bee venom has been used as treatment for arthritis, and cantharidin product from blister beetles has been used in the treatment of certain urogenital conditions. Since the Roman Empire, it has been known that soldiers with maggot-infested wounds had better outcomes in their wounds than those with un-infested wounds. In fact, the role of blow fly larvae in treating wounds andShow MoreRelatedThree Representative Organisms609 Words   |  2 Pagesthe center of the back (Coleoptera, General Entomology, 2012). The complete development cycle of beetles consists of the conventional egg, larva, pupa, and adult progression. The class is divided into four suborders. The most common are Aedephaga and Polyphaga. In the case of Aedephaga, the first abdominal sternum is divided by the hind coxae and in the case of Polyphaga the first abdominal stern um is undivided (Coleoptera, General Entomology, 2012).

Forensic investigations take different roles and turns in the investigations to ensure that they arrive at the desired results. One aspect of forensic investigation is entomology. The act involves the use of insects and their arthropod relatives that aid in decomposing remains to aid legal investigations. The insects in this case, can be used to approximate the time of death and this helps investigators determine the period within which the crime was committed. During these cases, the investigatorsRead MoreThe Importance Of Psychology In Your Life960 Words   |  4 Pagespattern of brain activity.

The broad field of forensic entomology is commonly broken down into three general areas: medicolegal, urban, and stored product pests. The medicolegal section focuses on the criminal component of the legal system and deals with the necrophagous (or carrion) feeding insects that typically infest human remains. The urban aspect deals with the insects that affectRead MoreHow does the number of maggots in the mass affect the temperature of maggot mass and development of maggots in the mass?2709 Words   |  11 Pagesresults. Introduction Forensic entomology is increasingly helping investigators to uncover serious crimes against victims. Insects make up more than a half of all existing species of living creatures on the Earth. They can be found nearly in all habitats. Fly larvae are the most useful insects for forensic investigations because they have relatively predictable development times (2.). The source of insect food is a variety of chemical ingredients.

Since the rates of resistance were progressing faster than drug development, it is clear that an effective surveillance system was required.

Kelley-Hope and colleagues also believed in using management strategies such as insecticide resistance surveillance system to allow for early detection of resistance
