receptive stigma to ensure proper seed set for their offspring. Show how insects are different from centipedes and spiders. Bird Characteristics PowerPoint PPT Presentations The classification of insects can be complex but it is very important to group and identify insects so that they can be studied reliably. not their own; and 3) overlapping generations: offspring contribute to colony labor while their parent(s) (at least their mothers) are still alive and inside the colony. The first four orders are known as the Apterygote orders because all the adults are wingless. The economic importance of the group is immense. Beneficial Insect Guilds Insects that eat pests Parasites- Insects complete their life inside a pests ( parasitic wasp) Predators - Insects that consume other insects (lady beetles) Pollinators - Insects that move pollen between plants (wasps, bees and flies) Decomposers - Insects that feed on dead and decaying plant and animal matter . The arthropoda characteristics are mentioned below: The body is triploblastic, segmented, and bilaterally symmetrical.

The most common eusocial insects are bees, wasps, ants, and termites (Table 1). Use various techniques to combat insect a. The PowerPoint PPT presentation: "Common insect orders" is the property of its rightful owner. Sufficient food production for a growing human population has become an issue of global concern. 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. Orthoptera: grasshoppers and locusts For more information on plague locusts visit the Australian Plague Locust Commission tralian Plague Locust Commission. In an order, there are classes, orders, suborders, families and genera, which constitute the living things that procreate with one another. Living organisms can be classified according to their characteristics. wasps, beesants, and , termites. Incomplete metamorphosis is characterized by immature insects that resemble adults and change mostly in size and the development of wings and genitalia. 4. Two Orders of winged insects, the Ephemeroptera and Odonata, have not evolved this wing-flexing mechanism, and their axillary sclerites are arranged in a pattern different from that of the Neoptera; these two orders (together with a number of extinct orders) form the Paleoptera. There are more known flies than vertebrates. and a few others.) More than 1 million of the categorized 2 million species are arthropods . 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 Hymenoptera, while the termites are in the Order .

Insects can also be adapted to their . • 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) and type) Protura Proturans Chewing Lacking Collembola Springtails Chewing Lacking Diplura Diplurans Chewing Lacking Microcoryphia Jumping bristletails Chewing Lacking Thysanura Bristletails, silverfish Chewing Lacking Orthoptera is the order of insects that includes grasshoppers, locusts, crickets, katydids, and their relatives. 2. Control of insects a. Considered here are some of the more important orders which are likely to be encountered. Insects are adapted their environment in many ways. Physical Characteristics The maximum obtainable length of timber piles is of the order of 110 ft, but lengths over 80 ft are scarce. Not very selective b. 47 North American (NA) species, 580 species worldwide (WW). Resistant crops 2. Segments grouped into 2 or 3 regions known as Tagmosis iii. 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. Entomologists, scientists who study insects, might also add that insects have a pair of antennae and external mouthparts. Animals that have webbed feet are adapted for living in the water. The insect's body is divided into three functional regions (tagmata): head, thorax, and abdomen. • Basal or generalized insect mouthparts Many of these are of minor importance and are studied only from the standpoint of scientific interest. Grow by . Insects, their characteristics, other Arthropods and birds that eat bugs . 1. Most orthopterans are large- or medium-sized insects. Classification - Insects Orders Illustrated (3-6th) (Printable Version at Bottom) Kingdom - Animals. 8. Resistant crops 2. Normally, these are tiny and don't grow very large. 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 .
