Branch 3 Structural Pest Control Study Overview Rated A+

Branch 3 Structural Pest Control Study Overview Rated A+ Species Groups of plants or animals that look-alike with similar characteristics and living traits Hexapoda The Class that all insects belong to, formally "insecta" Chordata The most familiar Phylum that includes the mammals, birds, reptiles and fish "vertebrate pests" Mollusca Phylum that includes snails, clams, etc. These are also tiny organisms, almost too small to be seen with the naked eye, called protozoa. Arthropoda largest phylum by far that contains the largest class,"Hexapoda". no one feature alone will separate the Arthropoda from all other animals. Segmented bodies, jointed appendages, shell like body "exoskeleton". They also have bilateral symmetry. (Each side of the body is the same as the other) Crustacea water inhabiting animals which breath either by gills or through the surface of their bodies. Numerous pairs of legs; two pairs of antennae, fused head to the body. Lobster, crawfish, crab, sowbug & pillbug Diplopoda Land animals which breath through air tubes on the side of their bodies. one pair of antennae, cylindrical bodies with a series of segments which look very much alike. each segment has two pairs of legs. "Millipedes" Chilopoda Have antennae and breath by air tubes. body is more flattened and each segment bears only one pair of legs. "centipedes" Hexapoda INSECTS: have three distinct body regions. The head, the thorax and the abdomen. they have only one pair of antennae, six legs that are all attached to the thorax. usually four wings if they have them that are also attached to the thorax. "Air tubes" Arachnida Have only two body regions, The cephalothorax and the abdomen. they do not have antennae and the cephalothorax bears eight legs. they breath with book lungs. Some smaller arachnids breath through surfaces on the body. 8 Characteristics of Insects 1. bilaterally symmetrical 2. segmented body 3. three body regions 4. exoskeleton 5. three pairs of jointed legs 6. one pair of antennae 7. two pairs of wings, usually 8. airs tubes for breathing Ametabola (No Metamorphosis) group said to have no metamorphosis. "Silverfish and springtails" Heterometabola (Gradual Metamorphosis) there is some change in the insect as it grows up other than merely a change in size. development of wings as the insect gets larger. Life Stages: Egg, Nymph, Adult (Roaches, grasshoppers, bedbugs, termites, stink bugs) Holometabola (Complete Metamorphosis) insects that have four distinct life stages. Usually the larvae live on entirely different food and do not resemble the adults. Egg, larva, pupa, adult.
