Parasitic Roundworms ( Cattle Bankrupt Worm )

There is a constant battle for farmers to find new and cost effective ways to rid their flock from endoparasites, in particular worms. Endoparasites are a parasite, for example worms, that live in the internal organs or tissues of a host. The most common species of worms that live amongst sheep in Australia are Haemonchus contortus (barbers pole worm), Trichostrongylus colubriformis (Black scours worm) and Teladorsagia circumcincta (brown stomach worm); all of these worms are examples of roundworms. The type of roundworm that is most commonly found in Queensland and the northern half of NSW is the barber’s pole worm. This is due to the climate of these two States where summer rainfall is common or dominant. The barber’s pole worm is located

For the farmers of south east QLD (Australia), Barbers Pole worm is the main worm internal parasite infecting their sheep. This is due the amount of rain and the summer heat. Due to the weather and the climate of south east QLD, makes it the perfect environment for the Barbers Pole worm to infect the sheep. The Barbers pole life cycle is as so, once the barbers pole worm has laid its eggs in the stomach of the sheep, (barbers pole worm can lay up to 10,000 eggs per day), the worm eggs move through the digestive track and are mixed in this the fesses, the fesses are pooped out and into the land, the eggs hatch within 4-10 days, they will hatch faster in hot climate and slower in cold. Once the eggs have hatched they begin to feed on the bacteria

The purpose of this assignment is to learn, observe and experience the biology of the Tobacco Hornworm through the different stages of its lifecycle, along with describing the processes which occur through each development stage. When I picked up my hornworm, I received three eggs in the tubular container. During my examination, the hornworms lived in two environments. They first lived in the small, tubular container they arrived in until they outgrew it. I then placed them in a large plastic container for the remainder of their lifecycle.

March-April: They lay their eggs on the leaves of milkweed plants. The larvae eat, grow and metamorphose into chrysalis.

Small birds and mammals because they forage for seeds. A tiny amount of the parasite needs to be ingest to begin causing problems and it can be found in raccoon feces.

Females lay white spherical eggs on the trunk, and produce a yellow viscous material from the ovipositor which is smoothed over into a covering, before fading to white or grey. Larvae exit the egg directly into the plant, never becoming exposed, and so are impervious to sprays. Young larvae are restricted to the cambium, circling the cane 3-4 times in a close spiral, girdling the primocane, and producing gall-like swellings. As larvae grow, they extend feeding deeper into wood and pith, and staightening the spiral and heading usually toward the distal end of the cane (tunnels may extend 15 cm below to 64 cm above the gall). Larvae reach a length of 12 mm, and have a pair of horn-like projections on the posterior end. The larvae are white and legless, with a flattened head (the family is often called flat headed borers). Larvae winter in the cane, and in March create a pupal chamber. The pupa is formed in late April. The pupal period lasts 20-40 days. When the adult leaves the pupal skin, it remains in the tunnel for about 10 days before chewing a D-shaped emergence hole. Adults feed on foliage for several days before beginning oviposition. They are most easily found on the plants on warm sunny days. There is one generation

Tapeworms that infect beef is called Taenia saginata (beef tapeworm), Taenia solium (pork tapeworm), and Diphyllobothrium latum (fish tapeworm). The pork and beef tapeworms are large and flat, they can grow up to 15 to 30 feet long. When a human ingests pork tapeworms they can become an intermediate host, which means they are able to become the host that can transfer the tapeworms to other humans. This can happen if the infected person does not wash there hands properly and has feces on hands that have the eggs in it or by swallowing the pork tapeworm egg in food or water contaminated with human feces. They can also transfer the eggs to there mouth after contact with an infected person or with contaminated clothing and furniture. The fish tapeworm is the only one that can cause inadequate absorption of nutrients causing anemia due to it absorbing B12 from your system necessary for red blood cells to

Adults emerge from surrounding areas to plant eggs in alfalfa stems during late winter, early spring. Larvae make their way up stems and cocoon/pupate by early

Barbers Pole worm (Haemonchus contortus) is most commonly found in southern Queensland and Northern New South Wales it is most common to find the worms here because is humid but no to humid in order to kill off the worms and not too cold to kill the worms. Refer to figure 1 in order to see where about they are most commonly found. The Barbers worm is found in the 4th stomach (abomasum) they live in that area of the stomach because the most common way to detect weather or not there is any worms in the stomach is to conduct a worm egg test commonly known as FEC (faeces egg count).

In summer the worm lives, but then when the season of winter the worm dies.

The new guinea flatworm is from the united states of America.this worm is native to the island of New Guinea where it was originally to have been found in. You can find these worms in tropical areas,coastlands ,planted forests, riparian zones shrubs and urban areas as well.it feeds on earthworms ,slugs and arthopods. This worm can harm the snail called The Giant East African Snail. This worm also can mainly eat mollusks and it especially likes to prey on snail. To hunt for it's prey the worm deposits itself to the bottom of a cabbage leave. It also can follow snail mucus trails to find it`s trail. It also has a infectious rate at least 14.1% and this thing usually lives on cabbage leaves. This worm not only affects the whole population of animals or a specific area this worm can affect humans as

Economic threshold depends greatly on the height of the plant. On average “around 20 or more larvae per sweep” (UC IPM, 2011).

The goldenrod gall fly (or Eurosta solidaginis) is a parasite whose life depends upon and revolves around the goldenrod plant. After mating, the female gall fly uses its ovipositor (structure used to inject eggs into a plant) to insert its eggs into the stem of a goldenrod plant. After about ten days, the fly larvae hatch and begin to eat the inside of the plant. The saliva of the larva contains a chemical that causes the plant to swell, creating what is known as a gall; this serves as a food source and a protective shell for the growing larva. When fall approaches, the larva digs an escape tunnel by which it will later exit the gall as an adult; however, the larva does not complete the tunnel, instead it leaves a thin membrane of plant material for protection (Abrahamson & Heinrich, n.d.). E. solidaginis larvae then pupate in late winter or early spring, and leave the gall as adults soon afterwards (Abrahamson, Sattler, McCrea, & Weis, 1989). Once freed from the gall,

Glow worms are found in the artic, caves, and in dense woodland. Glow worms are animals that tend to have a meat based diet. They eat slugs, snails, and other small insects. The glow worm’s conservation status is threatened. The glow worm is long and fat. They are really small. And they have a green light on their tail.
