Classification “What is a locust?” When we classify animals we need to put them into groups. First of all we need to see if they are vertebrates, which mean that they have a backbone like us, or invertebrates which means that they don’t have a backbone. Is your locust an invertebrate or a vertebrate? Locusts are also Arthropods. These are all of the small invertebrates with jointed legs and a hard skin called a cuticle. Arthropod actually means “Jointed Legs” in Latin. Arthropods include insects, spiders, millipedes, centipedes and crustacea (like crabs). Insects have three main body parts, the head, thorax and abdomen. All insects have three pairs of legs and they have joints where the legs bend. Most insects also have one pair of antennae, compound eyes and one or two pairs of wings. Do you think that locusts are insects, spiders, millipedes, centipedes or crustacea? We can classify our locust still further! There are lots of different groups of insects. We call these Orders. You may have heard of some of them: Type of insect Order True bugs Hemiptera Beetles Coleoptera Fleas Siphonaptera True flies Diptera Butterflies and moths Lepidoptera Bees, wasps and ants Hymenoptera Grasshoppers and crickets Orthoptera Locusts are in the order Orthoptera. This includes grasshoppers and crickets. Locusts are large grasshoppers. There are lots of different types of locusts. We can also put them in more groups, but the smallest group is called a species. This only has one type of animal in it that is able to interbreed. All breeds of dogs, for example, belong to the same species because they can all breed with each other. When scientists first started to classify plants and animals in the 17th and 18th centuries they wrote in Latin or Greek, which we still use today. If you could understand these languages then the words may help to describe the insect. Orthoptera actually means “straight wing”. Our classification is: Common name: The desert locust Scientific name: Shistocerca gregaria Kingdom: Animal Phylum: Arthropoda Class: Insecta Order: Orthoptera Suborder: Caelifera Family: Acrididae Genus: Shistocerca Species: gregaria 1.

Phylum Arthropod Silvia Rondon, and Mary Corp, OSU Extension Entomologist and Agronomist, respectively Hermiston Research and Extension Center, Hermiston, Oregon Member of the Phyllum Arthropoda can be found in the seas, in fresh water, on land, or even flying freely; a group with amazing differences of structure, and so abundant that all the other animals taken together are less than 1/6 as many as the arthropods. Well-known members of this group are the Kingdom lobsters, crayfish and crabs; scorpions, spiders, mites, ticks, Phylum Phylum Phylum Class the centipedes and millipedes; and last, but not least, the Order most abundant of all, the insects. Family Genus The Phylum Arthropods consist of the following Species classes: arachnids, chilopods, diplopods, crustaceans and hexapods (insects). All arthropods possess: • Exoskeleton. A hard protective covering around the outside of the body (divided by sutures into plates called sclerites). An insect's exoskeleton (integument) serves as a protective covering over the body, but also as a surface for muscle attachment, a water-tight barrier against desiccation, and a sensory interface with the environment. It is a multi-layered structure with four functional regions: epicuticle (top layer), procuticle, epidermis, and basement membrane. • Segmented body • Jointed limbs and jointed mouthparts that allow extensive specialization • Bilateral symmetry, whereby a central line can divide the body Insect molting or removing its into two identical halves, left and right exoesqueleton • Ventral nerve

Guidance for POP Pesticides
Guidance for POP pesticides 1. Background on POP pesticides POPs Pesticides originate almost entirely from anthropogenic sources and are associated largely with the manufacture, use and disposition of certain organic chemicals. Of the initial 12 POPs chemicals, eight are POPs pesticide. In the new POP list, five chemicals may be categorised as pesticides. These are alpha hexachlorocyclohexane (alpha-HCH), beta hexachlorocyclohexane (beta-HCH), Chlordecone, Lindane (gamma, 1,2,3,4,5,6- hexaclorocyclohexane) and Pentachlorobenzene. This module addresses baseline data gathering and assessment of POPs pesticides. Particular care is required to address DDT due to its use for vector control and Lindane due to its use for control of ecto-parasites in veterinary and human application, which may be under the responsibility of authorities other than those responsible for primarily agricultural chemicals. In addition, it is important that all uses of HCB, alpha hexachorocyclohexane, beta hexachlorocyclohexane and pentachlorobenzene (industrial as well as pesticide) be properly addressed. Specialists with knowledge of each of these areas might be included in the task teams. 2. Objective To review and summarize the production, use, import and export of the chemicals listed in Annex A and Annex B of the Convention (excluding other chemicals listed under Annex A and B which are not considered as pesticides). To gather information on stockpiles and wastes containing, or thought to contain, POPs pesticides. To assess the legal and institutional framework for control of the production, use, import, export and disposal of the chemicals listed in Annex A and Annex B (excluding other chemicals which are not classed as pesticides) of the Convention.

There are three 13-year America. There is probably no insect that attracts as cicada broods (XIX, XXII and XXIII) and 12 17-year much attention in eastern North America as does the cicada broods (I-X, XIII, and XIV). Also, there are three periodical cicada. Their sudden springtime emergence, distinct species of 17-year cicadas (M. septendecim, filling the air with their high-pitched, shrill-sounding M. cassini, and M. septendecula) and three species of songs, excites much curiosity. 13-year cicadas (M. tredecim, M. tredecassini, and M. tredecula). Two races of the periodical cicada exist. One race has a life cycle of 13 years and is common in the southeastern In Tennessee, Brood XIX of the 13-year cicada had a United States. The other race has a life cycle of 17 years spectacular emergence in 2011 (Map 1). In 2004 and and is generally more northern in distribution. Due 2021, Brood X of the 17-year cicada primarily emerged to Tennessee’s location, both the 13-year and 17-year in East Tennessee (Map 2). Brood X has the largest cicadas occur in the state. emergence of individuals for the 17-year cicada in the United States. Brood XXIII of the 13-year cicada last Although periodical cicadas have a 13- or 17-year cycle, emerged in West Tennessee in 2015 (Map 3).

Vertebrates and Invertebrates
Vertebrates and invertebrates The animal kingdom is divided into two groups: vertebrates and invertebrates. Vertebrates have been around for millions of years but have evolved and changed over time. The word vertebrate means “having a backbone." Many animals have backbones. You have a backbone. So does a cow, a whale, a fish, a frog, and a bird. Vertebrates are animals that have a backbone. Most animals have a backbone that is made of bones joined together to form a skeleton. Our skeleton gives us our shape and allows us to move. Mammals, fish, birds, reptiles, and amphibians have Vertebrae backbones so they are all vertebrates. Each bone that makes up the backbone Scientists classify vertebrates into five classes: is called a vertebra. These are the • Mammals building blacks that form the backbone, • Fish also known as the spinal cord. The • Birds vertebrae protect and support your • Reptiles spine. Without a backbone, you would not • Amphibians be able to move any part of your body. Animals without a backbone are called invertebrates. Most The human animals are invertebrates. In fact, 95% of all living creatures backbone has 26 on Earth are invertebrates. vertebrae. Arthropods are the largest group of invertebrates. Insects make up a large part of this group. All insects, such as ladybugs, ants, grasshoppers, and bumblebees have three body sections and six legs. Most arthropods live on land, but some of these fascinating creatures live in water. Lobsters, crabs, and shrimp are arthropods that live in the oceans. Many invertebrates have skeletons on the outside of their A frog only has bodies called exoskeletons.

Introduction to Phylum Chordata
Unifying Themes 1. Chordate evolution is a history of innovations that is built upon major invertebrate traits •bilateral symmetry •cephalization •segmentation •coelom or "gut" tube 2. Chordate evolution is marked by physical and behavioral specializations • For example the forelimb of mammals has a wide range of structural variation, specialized by natural selection 3. Evolutionary innovations and specializations led to adaptive radiations - the development of a variety of forms from a single ancestral group Characteristics of the Chordates 1. Notochord 2. dorsal hollow nerve cord 3. pharyngeal gill slits 4. postanal tail 5. endostyle Characteristics of the Chordates Notochord •stiff, flexible rod, provides internal support • Remains throughout the life of most invertebrate chordates • only in the embryos of vertebrate chordates Characteristics of the Chordates cont. Dorsal Hollow Nerve Cord (Spinal Cord) •fluid-filled tube of nerve tissue, runs the length of the animal, just dorsal to the notochord • Present in chordates throughout embryonic and adult life Characteristics of the Chordates cont. Pharyngeal gill slits • Pairs of opening through the pharynx • Invertebrate chordates use them to filter food •In fishes the gill sits develop into true gills • In reptiles, birds, and mammals the gill slits are vestiges (occurring only in the embryo) Characteristics of the Chordates cont. Endostyle • mucous secreting structure found in the pharynx floor (traps small food particles) Characteristics of the Chordates cont. Postanal Tail • works with muscles (myomeres) & notochord to provide motility & stability • Aids in propulsion in nonvertebrates & fish but vestigial in later lineages SubPhylum Urochordata Ex: tunicates or sea squirts • Sessile as adults, but motile during the larval stages • Possess all 5 chordate characteristics as larvae • Settle head first on hard substrates and undergo a dramatic metamorphosis • tail, notochord, muscle segments, and nerve cord disappear SubPhylum Urochordata cont.

Fins, Limbs, and Tails: Outgrowths and Axial Patterning in Vertebrate Evolution Michael I
Review articles Fins, limbs, and tails: outgrowths and axial patterning in vertebrate evolution Michael I. Coates1* and Martin J. Cohn2 Summary Current phylogenies show that paired fins and limbs are unique to jawed verte- brates and their immediate ancestry. Such fins evolved first as a single pair extending from an anterior location, and later stabilized as two pairs at pectoral and pelvic levels. Fin number, identity, and position are therefore key issues in vertebrate developmental evolution. Localization of the AP levels at which develop- mental signals initiate outgrowth from the body wall may be determined by Hox gene expression patterns along the lateral plate mesoderm. This regionalization appears to be regulated independently of that in the paraxial mesoderm and axial skeleton. When combined with current hypotheses of Hox gene phylogenetic and functional diversity, these data suggest a new model of fin/limb developmental evolution. This coordinates body wall regions of outgrowth with primitive bound- aries established in the gut, as well as the fundamental nonequivalence of pectoral and pelvic structures.
