The Queensland fruit fly is significant pest for many states and attacks a wide range of plants which decreases the production and making fruits inedible. This has large consequences for the local and international fruit and vegetable trade. The most common way that the Queensland fruit fly spread to new areas is by being carried interstate by infested fruit and vegetables. This fruit fly has a large potential to infest a large range of crops, garden plants, native plants and weeds. The female Queensland fruit fly is the main pest as it lays eggs inside of many fruits. The larvae then hatch of the fruit and eat the inside of the fruit which in turn destroys the fruit and deems it inedible. The larvae then shelter themselves in soil until they are fully formed flies. They then repeat the cycle and breed into fruits. …show more content…
South Australia is currently the only mainland state which is not infested with fruit flies.
This means that their fruit and vegetable industry is not only valuable to their state, but to the entire nation. Horticultural producers have a large amount of access to international export marks especially with New Zealand, Germany and Japan which are estimated to be worth $87 million a year. This access would not be available without the quarantine of the Queensland fruit fly. The citrus industry in particular saves a $4.2 billion a year due to the limited need for pesticides and any other pest controls. The Queensland fruit fly has outbreaks every couple of years, although they have been successful with its removal every time. South Australia remains under threat from a large number of fruit fly outbreaks throughout the state, so it is essential that prevention, detection and eradication measures continue so that the risk can be
reduced. The main exclusion zone is seen along the riverland area of South Australia as they need to protect the status of being a fruit fly area. The group responsible for the management of this exclusion area are the Government of South Australia, however they are consistent with informing the public about what they can do to prevent the risk of the Queensland fruit fly. Many strategies are put in place to ensure that fruit flies are not carried into the exclusion zone within South Australia. These include: large fines for anyone carrying fruit, vegetables or plant materials without a proof of purchase. Fines can exceed $100,000. The facilitatation of the movement of produce in accordance with each state's entry requirements. Series of fruit fly traps around the state that detect the presence of any fruit flies. They work with the public to ensure that they know how to identify when fruit flies may be infesting fruit. eradicate fruit fly outbreaks. monitor fruit movement with: quarantine stations where fruit and vegetables can be declared or disposed of and disposal bins where fruit and vegetables can be disposed of. Run digital advertsing, billboards and a 24 hour hotline for the prevention and control of the fruit fly. Lastly, the Government of South Australian invest in the discoveries of new technologies to keep fruit flies out of the state. All of these strategies have been seen to be extremely effective and made a significant contribution to the decline of fruit fly outbreaks within South Australia. These measures are also valid as even though fruit flys have out breaks on occasion, their prevention, control and treatment of the pest have evidently worked as there are currently no sign of the Queensland fruit fly in South Australia, in particular, the exclusion zone. Their management plans have been so successful as they include education the public about the risks and how they can play their part to ensure that the risk can always be kept in a manageable state. Providing education has significant impacts as the public are able to report any possible cases and know the signs of when the Queensland fruit fly may be present. The Queensland Fruit Fly is a problem for many states of Australia and has devastating affects on the production of fruit, but South Australia are able to successfully combat this threat but implementing management plans that have seen to keep the fruit fly out of their state. This means that South Australia has a wide income from their fruit production due to these management programs.
The objective of this experiment is to determine what genes are responsible for the white-eye color in two strains of Drosophila melanogaster, known as the common fruit fly. Drosophila is used as the experimental organism for many reasons which include its small size, easy maintenance, short 10 day generation time, and a fully sequenced genome. The characteristics of the wild type, which is the most common phenotype found in nature, include brick red eyes, long wings, gray/tan body, and smooth bristles. Of course, there are mutations that occur that cause specific traits to deviate from the wild-type phenotype. These traits include wing length, bristle shape, body color, and eye color.
Foreign plants which turn into weeds are continuously being introduced to Australia both accidentally and intentionally. They can cause extreme damage to Australia’s environment, as they threaten the survival of many native plants. They are successful in growing as they - usually grow faster than native plants competing for nutrients, water, space etc, they survive better as they do not have the pests and diseases that would normally control them in their natural habitats, they take over the native plants that the native animals use for shelter, food and nesting. The Cobblers peg (Bidens pilosa) also known as farmers friend, Spanish needle and beggars tick was introduced from South America and has become a weed in Australia. Individual flowers are yellow with white petals and do not last for very long, eventually turning into seeds.
Through a comparative study of Lord of the Flies by William Golding and The Mosquito Coast directed by Peter Weir it can be seen that both establish microcosm to epitomize the larger political concerns of the time. They also use the disparity of mankind in the natural world as a means of exposing the truth of human nature.
Amongst the boys which have be stranded on the coral island, There is one certain character, a character that is different from the rest of the boys, a character which is wise and understanding but most of all importance a character with a symbol. This character is Simon. He is one of the most symbolic characters from the beginning to end.
Importance of Leadership Leadership is something that stands out in people. In a group, people tend to look for the strongest person to follow. However, the strongest person may not be the best choice to follow. In Lord of the Flies by William Golding, Ralph and Jack each have leadership qualities. Jack is probably the stronger of the two; however, Ralph is a better leader.
From 1947 to 1991, the United States and the Soviet Union battled without a war. This conflict, the Cold War, was also notorious for the rivalry between the two countries. In literature, these rivalries also occur but are between characters or groups. In William Golding’s Lord of the Flies, two clans of boys, led by dueling protagonists Ralph and Jack, have their own battle on a desert island about how to survive. However, the title, Lord of the Flies, is not a complete representation of the themes. Although a “Lord of the Flies” would bite heavily due to being noble, the conflict is not basic and the title Lord of the Flies does not convey the plot effectively. The title Tribes of Fate is a culmination of all of the aspects of the story because the title incorporates the three-sided conflict of person versus person, person versus nature, and person versus fate.
My Essay is about Ralph and and his Motivation’s and did he contribute to the tragedy in any way. Also about if he prevented any of the deaths and what would I have done differently in his situation. I defend Ralph’s actions as leader, He had tried his best but everyone fell apart. Did Ralph contribute to the tragedies? Ralph had tried his best but he was struggling at handling the problems on the island, He was unaware of the boy’s and what was going on. He had tried to contribute to all of the tragedies but there was too much going on around him it was just hard. What was wrong with Ralph too was that jack ignores everything and try’s to do his own thing the whole time instead of working together with everyone. All Jack wants is his way or his way to him there is no other way. So yes Ralph had try to contribute to the tragedies but Jack and other boys had just did what they wanted to do instead of doing what they should have done. So Ralph had really struggled dealing with everybody. In my opinion Ralph was doing a good job, Yes he kind of gave up for a little b...
How are the characters of Ralph, Jack and Piggy established in the opening chapters of the novel Lord of the Flies At the start of the novel we learn that during a nuclear war, there was an atomic explosion. Many boys were evacuated on an aircraft with a detachable passenger tube. They were flying over tropical seas via Gibraltar and Addis Ababa when the tube was released and crashed-landed in the jungle of an island. The aircraft flew off in flames and overnight the remains of the tube were swept out to sea in a storm.
To most, the honeybee can be an annoying insect that has a powerful sting. Yet, the honeybee is so much more than just another insect. The honeybee is arguably the most vital component in the development of our food crops. With roughly 90 percent of our food crops dependent on the pollination of our honeybees, our food system, agricultural development, and diet rest on the work and well being of these buzzing insects. Unfortunately, since 2006 there has been a major decline in the population of honeybees, and has gotten progressively worse because of colony collapse disorder. The first reported increase of CCD was documented in November 2006 in Florida. By February 2007, several states began reporting major losses associated with CCD, ranging from 30% to 90%. A little over a half decade later in 2012 the attention paid towards CCD has grown substantially with more research being done as CCD continues to get worse. The main culprit for CCD, as research has suggested, is the use of pesticides on our food crops. With major corporations such as Bayer making millions and millions of dollars in profit each year in the distribution of pesticides, it is no wonder that nothing is being done to stop this practice despite evidence linking the use of pesticides and the drastic deterioration of the health of honeybees. With the continuation of the use of deadly pesticides and the vital role bees play in the pollination and development of our food crops, both the environment and our economy will be effected directly and face the potential for catastrophic results.
Lord of the Flies: Final Essay Exam. Are the defects of society traced back to the defects of human nature? The defects of society, and how it relates to the defects of human nature, can be explained with the savagery that drives the defects of society and the same savagery that drives the defects of human nature. In this story, Lord of the Flies, Golding shows the id, ego, and superego within the characters in the book. Golding represents the id with Jack, whereas the id says “I want, and I want it now,” and Jack constantly wants and needs power, and wants his way in every situation.
The novel; “Lord of the Flies” is a highly renowned novel written by William Golding and published in 1954. The novel embodies many themes and events that are mysterious and unanticipated for the reader. During the course of the essay I will explain how the conch shell that is found at the foundation of the first chapter plays a significant role throughout the novel and how diverse themes are brought on from this influential shell. This essay will express an opinion on the conch shell, in the end has more power and order than the actual ‘beast’ that is signified on the island. I will also explore the social leadership of the conch throughout the novel which will also touch on a few themes that the conch shell plays a role in. The conch shell is one of the first real theme/symbol that readers are introduced too and stands its power for most of the novel which is why it should be explored in further detail in this essay.
Now I know the thought of eating a bowl of insects for your lunch does not appeal to the most part of the UK. But without these changes in the future our eco system may not be able to support itself, and that is a severely disconcerting thought. Although we may be quite far away from this change, we must start the gradual progression into trying new and exotic foods to ease the country into this lifestyle. Besides, I hear they are quite tasty.
Insect pollination as we all know, is the process that enables reproduction and fertilization by the transfer of pollen performed by insects. Insects are some of the oldest pollinators of plants. Pollinating insects date back to 140 million years ago. Since then, due to how effective insect pollinators are, these flowering plants have become the major group of terrestrial vascular plants. Flowering plants, also known as angiosperms, have imperative roles within our ecosystems, both natural and agricultural. For instance, insects provide food, fiber and shelter for wildlife and humankind alike (2007). It is commonly know that in humans, high levels of fruit and vegetable consumption are associated with decreased risk of chronic disease (Calderone 2012). Aside from these important roles, plants have also been considered as a viable option for fuel sources (Calderone 2012). There are around 300,00 species of flowering plants in the world and without pollination, the reproductive process would be very difficult since pollination causes the production of seeds (Calderone 2012). Of the 300,000 plant species worldwide, a little over 3,000 of these plants have been used as a source of food. Close to 300 of these species are grown around the world today and only 12 of these plants make up about 90 percent of the food sources in our world. These 12 include the grains...

“Spread your wings and fly” they said, well it’s not that easy. It all started when I was a caterpillar, I wasn’t bothering anybody, I was just minding my own business eating a leaf on the tree. All the sudden I see a couple of birds flying around me. When I noticed them I just wanted to get out if there because my aunt Ruthie was just eaten by a bird. It was a sad time.
