To better understand the mechanisms involved in the insect behavioural response to stimuli, it is necessary to introduce the concept of insect learning. Darwin was the first who gave importance to the psychic activities of animals and to address scientifically the problem of instinct or innate behaviour (Dukas, 2008). Insects use instinct to manage many type of different situations, most of them predictable. Animals, including insects, need to know such things as what food is good to eat, when and where to find it, whom to avoid and approach, with whom to mate, and how to find its way home. When these things are not genetically pre-programmed, the animal must learn them. Learning can be defined as a persistent change in behaviour that occurs …show more content…
Forward, it will acquire new skills and knowledge through trials and errors, observation of other individuals, or memory of past events. In general, learned behaviours are non-heritable because they are acquired just throughout observations and/or experience; permutable because, in fact, the sequence of behaviours may possibly change over time; adaptable due to their capacity of modification in order to adapt to different conditions, and finally, they are progressive because they could be improved trough practice and training (Giurfa and Menzel, 2013). Insects have relatively simple nervous systems, and they have demonstrated the ability to learn in each of the following ways such as habituation, sensitization, pseudonditioning, classical conditioning and instrumental conditioning (Dukas, 2008). Learning is divided into non-associative learning which includes habituation, sensitization, pseudoconditioning and associative learning which includes both classical and instrumental conditioning (Giurfa and Menzel, 2013). In this essay the non-associative learning will not be …show more content…
As a consequence, landmines injure and kill a huge number of people every year and the presence of unexploded landmines can also negatively affect the environment and the economy of a determined country (Kasban et al., 2010). In fact, landmines are responsible for the non-usage of entire areas of lands that could be use for agricultural purposes or livestock (Kasban et al., 2010). The conventional demining system is characterized by a deminer and a demining crew. Firstly, the demining crew clears the suspected area of vegetation and divides it into lanes of one metre, secondly, the deminer goes through each lane using a handled metal detector and a device (for example a pointed stick) to detect the presence of any mines. In case that the metal detector indicates the presence of a mine, another deminer will check and confirm whether it is a mine or not. This procedure should be done as fast as possible but unfortunately, this process requires long time and, especially, high costs (Habib, 2007). Moreover, another disadvantage of this conventional technique is that the metal detector signals every type of metal fragment that it finds, without giving any information about whether the piece is really a mine. The result is

Home in The Secret Life of Bees Sonsyrea Tate’s statement about “home” aligns with Sue Monk Kidd’s novel, The Secret Life of Bees. In this novel, the main character, Lily Owens, embarks on a Bildungsroman journey after leaving her birth home to find her true identity and “home.” The idea of “home” guides Lily on a path of self-discovery and leads her to the pink house and the feminine society that lies within, in which she finds true empowerment and womanhood in her life. “Home” plays an important role in Lily’s journey throughout the novel. Lily feels lost and alone at the Peach House with T. Ray because of his continuous physical and mental abuse.
ImageText BoxImageOne of the biggest threats to the environment of Ontario is the Gypsy Moth (Lymantria dispar dispar). The species itself is native to Europe and Asia. How this affects us is by weakening trees across Ontario and North America. The first time the gypsy moth was found in Ontario was 1969. The gypsy moth can be found in southern Canada (Ontario), New Brunswick, Nova Scotia and British Columbia. It is known to weaken trees and the caterpillar form live in trees and during most outbreaks its caterpillar feces would fall from the trees to the ground or even on top of humans. The average Gypsy Caterpillar can grow 5-6 centimeters long. With five pairs of blue spots and six pairs of bright red dots on their back. The female moth are white and can fly on the other hand, the male moth are brown and can also fly. The female have a 5cm wing span but male have a 2.5cm wing span. The gypsy moth usually lives in open forests and other forests and take up at least 20% of the space. The Gypsy moth are about 4cm long, tan coloured and can be located on tree trunks, furniture, and buildings. (OFAH Invading Species Awareness Program, 2012)
Cephalopods are known to be exceptionally intelligent by invertebrate standards and in some respects even rival “higher” vertebrates. These animals have many highly evolved sensory and processing organs that allow them to gain a greater understanding of their environment and their place within it. Due to their advanced structures, many of which are analogous to vertebrate structures, and abilities they have been widely studied. Their methods of learning have been of prime interest and many experiments have been conducted to determine the different ways in which octopuses can learn. From these experiments four main kinds of learning have been identified in octopuses: associative learning, special learning,

“‘I’m staying here,’ I said. ‘I’m not leaving.’ The words hung there, hard and gleaming. Like pearls I’d been fashioning down inside my belly for weeks” (Kidd 296). This is one of the examples in Sue Monk Kidd’s novel, the Secret Life of Bees, where Lily has finally transitioned into adulthood. The author communicates the message that throughout the novel Lily endures an emotional struggle that helps build her into the woman she is at the end of the novel with indirect characterization, allusions, and symbolism. These literary devices display the characters’ emotions and feelings throughout the book. In doing this, Kidd establishes the relationships between Lily and the people around her as ones that giver her a hard time, but teach her to be more strong. Therefore, the author included literary devices as a method of emphasizing the maturing of Lily through hardships that she eventually resolves.
In observational learning, a child takes note of what his or her mother or father considers to be threatening. On the other hand, children can also be conditioned by their own life experiences through a process called operant conditioning (SOURCE). In some instances, children tend to generalize their fears, subsequently forming a phobia. For example, a young girl who became increasingly cautious of flying insects after an unpleasant encounter with a nest of agitated yellow jackets. After being assaulted by these creatures, she associated all flying bugs with the painful sting of a yellow jacket. Of course, children can also be classically conditioned to display a fearful response; that is, they learn to associate an unconditioned fear-relevant stimulus with a conditioned stimulus, provoking a conditioned, fearful response. One of the most well-known examples of this is an experiment involving a young boy, famously dubbed Little Albert. Little Albert learned to fear small furry animals in a laboratory setting when the presence of these creatures was paired with loud banging noises (SOURCE). From the aforementioned experiments and studies, it is undeniable that external circumstances and experiences assist in the configuration of fear in
In a world where every individual desires to acquire money, prosper, and make a life for themselves nevertheless no part of my being aspires any of it. My life's work wants nothing more than to help other people because at the end of the day, my long list of people I have helped will be worth more than your money. The way I grew up, I would have been the same way as everyone else, but it was with the experiences I have gone through along with my favorite movie, book, quote, historical figure, and my very own personal hero which all single handedly helped mold me to the person I am glad to be today.
What can we actively take part in to stop the collapse of bee colonies? Bees are such a vital part of our everyday agriculture production, however, colonies are diminishing before our eyes. Colony Collapse Disorder is a massive decrease of bees in hives and it is greatly affecting our crops because bees are not distributing the necessary amount of pollen to crops in order for them to grow the maximum, most nutritious produce possible. There are many solutions that may help CCD, such as banning neonics, urban beekeeping, and interbreeding honey bees with African killer bees. The most effective way to decrease CCD is by interbreeding honey bees with a stronger specie of bees labeled African killer bees.
Forensic entomology is the learning of all types of insects and how they connect with criminal investigation. Forensic entomology can tell us how long since the offspring’s death which is known as postmortem interval (PMI) and whether the body has been relocated since putting one foot in the grave, and what injuries it may have suffered. At the start of decomposition, insects launch a new community by hatching eggs on the remains; the eggs will emerge into cankers (larvae) that will graze upon the human organs and tissues. A Forensic entomologists can figure out what specific bugs are presently in the body and gauge how long the body has been left unprotected by investigating how far along the cankers have come; although, what is found isn’t
Drosophila melanogaster, commonly known as fruit fly, is mainly used as a human disease model organism for genetic analysis. It was during the 20th century that D. melanogaster was considered as the most significant model organism. D. melanogaster is small in size, and it has a short life span with a good reproduction rate, perfect for raising in large number and generation counts for genetics experiments. Additionally, it has a small genome which makes it easier for geneticists to keep track of changes in molecular level. Geneticists were able to uncover many human genetic diseases through the homologous genome of human and fruit flies. It started out with a small group of people led by Thomas Hunt Morgan at Columbia University. Many principles and rules of transmission genetics that are still being used in the generation of today were established in the laboratory of Dr. Morgan. Many animal models were being used before fruit flies. Using the whole-animal as a model set limitations to the types and amounts of experiments can be conducted. The use of Drosophila was able to led geneticists to overcome these limitations with tremendous promises in finding greater quality results. It was Frank Lutz, who wrote many papers on Drosophila, which introduced Drosophila to Dr. Morgan. Many experimental works on plants and animals were carried out on Drosophila instead. Through Drosophila, the discovery of mutation, recombination, relocation of chromosome, and many others were made possible. The cinnabar, cn, gene encodes an enzyme essential in the eye color formation of drosophila. It codes for the enzyme, kynurenine-3-monooxygenase, that is essential in the biological pathway of ommochrome for the brown pi...
Antipersonnel landmines kill thousands of people every year. Antipersonnel landmines do not recognize a cease-fire; they continue killing or maiming for many years after the conflict is over. Antipersonnel landmines do not discriminate between soldiers or civilians. On the contrary, more and more they are being used in an indiscriminate way, terrorizing civilians and transforming agricultural fields into killing fields. In addition, de-mining is a very slow and very expensive process, and after a war most countries are not prepared to cope with the constant health care demands imposed by the number of injured by landmines. Finally, landmines make it very difficult for refugees to go back to their cities and villages. As response to the landmine problem, the international community has come up with a treaty to ban landmines. On March 1, 1999, the 1997 Mine Ban Treaty came into effect; so far 134 countries have signed the treaty. Unfortunately, the U. S. is not one of them.
Child and Insect is a lovely poem about the disappointment in life, which a little boy is just running into and starting to realize. Robert Druce has portrayed a simple but very appealing image of a very humane situation in a child’s life. The writer has delivered his massage to the readers trough a game of the little boy and the grasshopper. Child and Insect is a poem filled with great a variety of literary terms such as alliteration, symbolism, onomatopoeia, repetition, comparison, contrast, personification and run on lines which work all together in order to reveal three different stages in the poem characterized by a drastic change in the mood and the tone of the writing.
Learning is defined as a “process of change that occurs as a result of an individual’s experience” (Mazure, 2006). Researchers assume that the process of learning follows certain general principles, which were developed, into the general process learning theories. These include operant conditioning and classical conditioning which has been put forward by leading psychologists like Pavlov, B.F.Skinner and Thorndike. However, in learning, operant and classical conditoning are opposed by biological constraints that state that there are limitations to the theories. Some of these biological constraints on learning will be discussed below.
