The clinical importance of Insects to Man
Insects are by far the largest group of organisms (Class Insecta) on earth. Whether measured in terms of numbers of species or numbers of individuals. Insects live in every conceivable habitat on land and fresh water, and a few have even invaded the sea. More than 70% of all named animal species are insects, and the actual proportion is doubtless much higher, because millions of additional forms await detection, classification and naming. Most insects are relatively small, ranging in size from 0.1mm to head, thorax, and abdomen; three pairs of legs, all attached to the thorax; and one pair of antennae. In addition, they may have one or two pairs of wings. Most insects have compound eyes, and many have ocelli as well. The mouth parts of insects are elaborate. They usually consist of the jaws or mandibles, which are tough and unsegmented; a secondary pair of mouth parts, the maxillae, which are segmented; and the lower lip, or labium, which probably evolved from the fusion of another pair of maxilla-like structures. The upper lip, called the labrium, is of less certain origin. The hypopharynx is short, tongue-like organ (in chewing insects) that lies between the maxillae and above the labium, the salivary glands usually open on or near hypopharynx. Within this basic structural framework. the mouth parts vary widely among groups of insects, mainly in relation to their feeding habits. Many orders of insects- such as Coleoptera, the beetles; Hymenoptera, grasshoppers, crickets, and their relatives- have chewing, or mandibulae mouth parts. In other orders, the mouth parts may be elongated or style-like. For example, in some flies (order Diptera) such as mosquitoes, black flies, and horse flies. there are six piercing, fused styles: the labrium, the mandibles, the maxillae, and the hypopharynx; the labium sheaths the stylets. In more advanced flies, the labium may be the principal piercing organ or may be expanded into large soft lobes through which liquid food is absorbed. The insect thorax consists of three segments (tagmata), each of which has a pair of legs. Occasionally, one or more of these pairs of legs is absent. Legs are completely absent in the larvae of certain groups- for example, in most members of the order Hymenoptera, the bees, wasps and ants- and among the flies, order Diptera. If two pairs of wings are present, they are attached to the middle and posterior segments of the thorax; if only one pair of wings is present, it is usually attached to the middle segment. The thorax is almost entirely filled with muscles that operate the legs and wings. The wings of insects arise as sack-like outgrowth of the body wall; in adult insects, they are solid, except for the veins. The internal features of insects resemble those of the other arthropods. Insects posses sophisticated means of sensing their environment, including sensory hairs to detect chemical signals called pheromones. Most young insects hatch from fertilized eggs laid outside their mother’s body. The zygote develops within the egg into young insect, which escapes by chewing its way out or by bursting the shell. During the course of their development into adults, young insects undergo ecdysis a number of times before they become adults and stop molting permanently. Most insects molt 4 to 8 times during the course of their development. The stages between the molts are defined as instars.</p><p><b>Metamorphosis</b><br>There are two principal kinds of metamorphosis in insects: simple and complete. In simple metamorphosis, the wings develop internally during the juvenile stages and appear externally only during the resting stages that immediately preceeds the final molt. During this stage, the insect is called a pupa or chrysais, depending on the group to which it belongs. A pupa does not normally move around much, although the pupae of mosquitoes do move around freely. A very large amount of internal reorganization of the insect’s body takes place while it is a pupa or chrysalis. In the insects with simple metamorphosis, the immature stages are often called nymphs. They are usually quite similar to the Adults, differing mainly in their smaller size, less well-developed wings, and sometimes in their color. More than 90% of the insects, including the members of all of the largest and most successful orders, display complete metamorphosis, in which the juvenile stages and adults often live in distinct habitats, have different habits, and are usually extremely different in form. In these insects, development is indirect. Larvae in insects are immature stages, often worm-like, which differ greatly in appearance from the adults of the same species. Larvae do not have compound eyes. They may be legless or have legs as well as sometimes having leg like appendages on the abdomen. Pupae do not feed and are usually relatively inactive. As pupae, insects are extremely vulnerable to predators and parasites, they are often covered by a cocoon or some other protective structure. Groups of insects with complete metamorphosis include the moths, and butterflies; beetles; bees, wasp, and ants; flies and fleas.</p><p>I am Funom Theophilus Makama. I advertise through writing.

Things You Need to Know to Enhance Your Insect Collection
Create a fascinating and educational insect collection display to showcase your favourite species.
This way you can develop a much better appreciation for your entomology collection while showing it off to friends and family at the same time.
One of the best ways to augment your existing bug collection is to simply upgrade the general appearance.
You can begin by neatly arranging each of the different types of species into an orderly fashion inside a simple box or container. The best way to arrange this is from the top to the bottom and from the left side to the right side. The box or container should be a standard size and cleaned thoroughly before use. You can paint or wax the box to make your insect collection stand out more.
When placing the insects into the box make sure to group the specimens under their correct order and family names. Line up each category of similar insect groups together wherever possible as this is necessary to maintain a proper order in your overall display. You can distinguish the different orders and families from each other if you include labels which are clearly typed in a neat and organized way.
The background color of your insect collection display is also important as helps to exhibit your collection in a much better manner. A standard white color is usually best but you can choose other lighter shades of colors as well such as blue, green or red.
When deciding which particular species to include in your insect collection display it is best to choose the insects that are in the best condition from your entomology collection.
For example, the wings on any butterflies or moths need to be properly spread. Antennae, legs, and other protruding body parts need to be properly positioned when attempting to dry them. When drying your insect collection you need to support the head and abdomen of large and less rigid specimens to prevent any type of sagging that may ruin the appearance. If possible, try to recreate realistic or life-like positions when displaying your insects.
You never want to display damaged or poorly mounted bug specimens. It is far better to display a properly mounted simple specimen as opposed to a badly mounted rare specimen.
To properly display each insect in your container you will need to pin each specimen so that they are level and not tilted at an angle on each pin. If you have long pins it is best to place each specimen at a similar height on the pins themselves so it does not look uneven. Make sure to pin the insects according to the order of each family group of each species.
After you have pinned all of your insect collection you will then need to produce labels that are neatly printed or written. For improving the education value of your entomology collection it is good to make sure each label contains sufficient data of the species being displayed.
Position the printed labels on the pins so they are level, straight, and facing the same direction. Group the labels into specific insect species groups to organize the placement of specimens within the container. These labels should be held down by the pins so that they lie flat against the bottom of the display box container.
To produce appropriate specimen identification labels you need to be as accurate as possible when identifying your insect collection. Order level is important while common species names are necessary but not always required.
Make sure that the mounting technique is appropriate for a particular specimen as you do not want to pin any immature insects. It is best to use fully grown or mature adult specimens only.
For the most visibly appealing insect collection display you should include a varied selection of insects from as many different species as possible. Do not allow one group of insects to dominate the collection and overshadow all the other specimens in your display which would make it imbalanced. The types of specimens you choose to display are more important in advanced insect collections. Choosing perfectly mounted rare specimens is the ultimate goal.
The best way to produce an educational experience for your entomology collection is to simply make an educational display box.
Educational display boxes are created to educate others something about your insect collection. These types of displays utilize similar insect boxes as the regular insect collection boxes but much more creativity is demonstrated in educational displays than in insect collections. Educational display containers teach almost any subject in regards with insects and usually feature real specimens as part of the box. Subjects often select and include comparisons of specific details such as insect body parts, camouflage, habitat, growth and development, behaviour, food resources, or other important tidbits of information topics.
To create a good quality educational display you will need to remember that the purpose of the educational box is to educate others.
Keep the description simple try not to teach multiple concepts within a single display. Make sure the information presented is scientifically accurate. Note a heading in the container that clearly lets the viewer know exactly what the display is about. The display should tell its own story in as few words as possible to get the point across. For the best results display something you have personally witnessed or experiments you have actually conducted and last, but not least, try to be original.
Now that you know all the necessary tips to improve your insect collection go ahead and try to create your own insect collection display. There is nothing better than knowing that you created a beautiful and educational display for your entomology collection with your very own hands.
