(There is no hemoglobin in insects except in immature Chironomus spp. The Insects (Class Insecta) are divided into a number of Orders. used to refer to large groups of insects, such as families or orders. • Female are more aggressive than male and usually dominant males. - Posess chitinous exoskeletion that must be shed during growth. Rhinotermitidae (Subterranean termites) — These insects build nests in the soil and generally infest wood that is in contact with the ground. their relatively low strength. The most common eusocial insects are bees, wasps, ants, and termites (Table 1). Isoptera. In body shape, aquatic nymphs resemble their terrestrial adults. The Animal Kingdom is a big place with insects being an important part of it. For the reader who is unfamiliar with the biology or ecology of insects, this primer will provide needed background information.

Insects have an open circulatory system, this means their "blood" is free floating, contacting organs Hemolymph: Insect blood Carry nutrients to tissues, carry away wastes, function in phagocytosis Insect blood cells that have engulfed bacterial or fungal invaders Unlike human blood, insect blood cells lack hemoglobin and do NOT carry oxygen From Central America, some greenheart and angelique are used. Physical Characteristics The maximum obtainable length of timber piles is of the order of 110 ft, but lengths over 80 ft are scarce. Insect compound eyes have thousands of more or less equivalent sensory cartridges called ommatidia. Understand ecology of insect pest 2. and a few others.) Insects can also be adapted to their . - Paired appendages (e.g., legs, antennae) are jointed. variousharacteristics are used to c group insects into orders (Table 1). This can be done with the help of a key. Body regions are not . Class Insecta - The insects c. Carry disease - mosquitos, fleas, flies 5. This family includes the most destructive species found in the United States: the eastern subterranean termite (Reticulitermes flavipes), the western subterranean termite (R. hesperus), and the Formosan subterranean termite (Coptotermes formosanus). their development, insects undergo a drastic change in form known as metamorphosis. Insects were counted , based on their order as they landed on the pillowcase in 30-minute intervals Insects were captured, identified, and then released so the correct order was assigned Insects were then allowed to disperse for 30-minutes The light covering was switched and the process repeated Literature Cited Gould, J. Characteristics of insect societies They live in groups of closely related individuals Individuals are usually faithful to their "family" Often live in a confined locality ("nest, hive") In eusocial insects Overlapping generations: parents live with offspring Members collaborate in raising the offspring Sterility of a large number of . Many of these are of minor importance and are studied only from the standpoint of scientific interest. The study of insects is a science called entomology. German scientist found that the worldwide economic value of the pollination service provided by insect pollinators, bees mainly was dollar153 billion in 2005 They are hardwoods and have considerable resistance to marine borers. Abstract. There were dragonflies as big as seagulls are today, and 225 million years ago some millipedes were 2.5 metres long and had a diameter of a few centimetres. Do the following: a.

Classification of Insect Orders ( from Wheeler et. INSECTS IN ANIMAL KINGDOM AND ITS RELATIONSHIP WITH OTHER ARTHROPODA Insects are invertebrates grouped in the phylum Arthropoda (Subphylum : Uniramia) Characters of the Phylum Arthropoda: (Arthro-joint, poda-foot) i. Segmented body ii. ( Beetles) The arthropoda characteristics are mentioned below: The body is triploblastic, segmented, and bilaterally symmetrical. Renewable chitinous exoskeleton iv. Also, regional and world catalogs are avail- able for many insect groups, and these are useful in determining synonymy and, in some cases, in providing . Animals with heavy fur coats are adapted for cold environments. By now as you know what invertebrates are, let's get to know about their characteristics. the insects Within the class Insecta, . Males can appear very different from females are their distinguishing characteristics are given below: The role of blood in insects is the transport of nutrients, wastes, and hormones. 2. The classification of insects can be complex but it is very important to group and identify insects so that they can be studied reliably. Birds, Birds, Birds - There are about 9,703 species of birds divided up into 23 orders, 142 families . Its reproduction is asexual by fission and its life cycle presents various body forms, there is also polymorphism within the trypomastigotic phase. Normally, these are tiny and don't grow very large. PHYLUM: Anthropoda. Control of insects a. They have three characteristics in common — a seg- Blattodea (cockroaches and termites) is one of the oldest extant orders of insects, with fossils of ancestral cockroaches dating to the Paleozoic, and those of modern-type cockroaches dating to the Cretaceous (>140 Ma) (Bell et al., 2007). Introduction of insect predators c. Integrated Pest Management 1. I can identify insects and the characteristics that place them in the six most common insect orders. A person who studies insects is called an entomologist. 1. Giant insects During the Carboniferous many of the insects and related arthropods reached a huge size. Insects are adapted their environment in many ways. Development of chemicals to kill insects 1. The order is one of the four largest groups of living organisms. There are two basic types of metamorphosis: incomplete and complete. Sort by . Use various techniques to combat insect a. Some new classifications and new insect Orders in current literature, but it is a good general reference. Insects orders. Find each part of the grasshopper's head listed in your lab printout. Introduction of insect predators c. Integrated Pest Management 1. FLOW: History of Philippine Entomology What is Entomology Importance of Insects to Man and Agriculture Classification and Taxonomy of Insects General Characteristics of Insects Insect growth and development Characteristics of each Insect Orders Concept Of Pest Short Quiz - 20 ITEMS FLOW: History of Philippine Entomology What is Entomology Importance of Insects to Man and Agriculture . These are grouped together into two sub-classes called the Apterygota (wingless insects) and the Pterygota (winged insects) - for further information on Classes, Orders and Sub-classes see the Classification section.In addition to the Class Insecta there are three other classes of invertebrates that have six legs, these three . Recent Classification of Orders of Insects Author: Gary Parsons Subject: Recent Classification of Orders of Insects Keywords: insect order; order of insects; insect family Created Date: 11/3/2016 11:54:21 AM The economic importance of the group is immense. Class Insecta - The insects c. Carry disease - mosquitos, fleas, flies 5. • Their geologic age . wasps, beesants, and , termites. Appendages of the thorax include the legs and the wings. The Class Hexapoda is generally studied under a classification system with approximately 30 orders. Insects have been hugely successful in terms of both species . Birds, Birds, Birds - There are about 9,703 species of birds divided up into 23 orders, 142 families . Members of several lineages of this order produce sounds using a mechanism known as stridulation. 3. You will need a good hand lens to observe some of the smaller parts of the insect, for example to count the number of segments in the tarsi, or to have a close look at the antennae. Body is divided into three regions 2. death . different insect orders located in Michigan. All invertebrates do not have a spinal cord or vertebral column, instead, most of them possess an exoskeleton that encompasses the entire body. Contestants will be expected to know the insects, their scientific order or family names, their food, and their ordinal characteristics as given in the list. The first four orders are known as the Apterygote orders because all the adults are wingless. Resistant crops 2. The 29 insect orders are numbered in an approximate series of evolutionary complexity, with the oldest and most primitive groups being listed first. Characteristics of Invertebrates. Not very selective b. ¾Cells are the smallest units that have all the characteristics of life ¾All organisms are composed of cells 8 Objective 4 d Concept: In order to maintain their high level of organization, as well Insect Biology and Ecology: A Primer. Animals that have webbed feet are adapted for living in the water. More than 1 million of the categorized 2 million species are arthropods . Some Common Insect - Some Common Insect Orders Silverfish and their allies. Insect Orders About 28 different orders of insects Divided into these orders based on structure of wings and mouthparts and their type of metamorphosis Ametabolous: growth without change Paurometabolous: incomplete or gradual Hemimetabolous Holometabolous: complete metamorphosis ( Cockroaches) COLEOPTERA. • Basal or generalized insect mouthparts A parasitic wasp (family Aphelinidae) has developed within this aphid, killed it, and emerged . Insect Orders - Introduction. also has several close contenders with the Andean . •Most insects have separate males and females and reproduce sexually •Individuals find and recognize members of their own species by bright colors, sound, or odors •Some insects are beneficial as pollinators, while others are harmful as carriers of diseases, or pests of crops •Insects are classified into more than 30 orders 4. These characteristics are easily visible and do not require a microscope; for example, mouthparts, wings, and type of metamorphosis are all identifying characteristics. Alternatives 1. KINGDOM: Animalia. Keys can be used to identify different species. It supports the eyes, antennae and and jaws of the insect Note: insects do not breath through their mouths, but through their thoracic and abdominal spiracles. insects, you will be fascinated with the wide variety of forms and their ways of life. insects have them. Only the cold arctic and antarctic ice caps are without flies. 8. In this introduction, we have described the insect orders beginning with the most primitive wingless insects, and ending with the insect groups that have undergone the greatest evolutionary change. Parasitic species deposit their eggs inside another insect, and the larva(e) develop within that "host," killing it only after the parasites are nearly mature. When trying to identify an unknown insect you will always first try to determine its correct Order. Phylum : Arthropoda (with several classes) Class: Insecta (Hexapoda) Characters of class Insecta 1. Their body has jointed appendages which help in locomotion. • Characteristics: - Small to large insects usually with two pairs of wings but apterous (wingless) forms are common - Wings when present, have larger forewings and heavier texture than hind wings (uniformity) - ( Homoptera) while in sub-order Heteroptera the tip of forewings is more membranous than the base (hemelytra) Here is an example using the marmalade hoverfly, Episyrphus balteatus: 19.17 Hoverfly migration.jpg. In head a pair of antenna and a pair of compound eyes are usually present. 1) Beetle Order - Coleoptera. All of the ants and termites are eusocial, while both the bees andwasps have many species that live solitary lives. Most orthopterans are large- or medium-sized insects. Members of this order include: a huge diversity of beetles, including ladybugs, fireflies, junebugs, stag beetles, weevils, burying beetles, rove beetles, click beetles, rose chafers, and many others. Their life cycle includes three stages - egg, nymph and adult. As you may remember from elementary school, the most basic definition of an insect is an organism with three pairs of legs and three body regions: head, thorax, and abdomen.
