1. Define Entomology. a. "Entomology is the study of insects." -P.J. Gullan and P.S. Cranston, 2010 b. "Entomology (from Greek ἔντομος, entomos, "that which is cut in pieces or engraved/segmented", hence "insect"; and -λογία, -logia[1]) is the scientific study of insects, a branch of arthropodology."
2. List down five branches of branches of entomology and describe it. a. Ecology and Behaviour - Ecology is the scientific study of interactions among organisms and their environment, such as the interactions organisms have with each other and with their abiotic environment while behaviour can be regarded as any action of an organism that changes its relationship to its environment. Behavior provides outputs from the organism to the environment. b. Taxonomy- It is the study of classification. Classification of insects and their relatives is also part in studying entomology. Classifications are tools that gives names for groups of species that serves as an easy way for communicating information about those species. c. Anatomy and Physiology- This is the study of the internal and external body parts of an organism where it is discussed anatomically (where it is found) and physiologically (what is its purpose). This is very important in studying entomology because throughout the class, the parts of insects will be described and pointed out. The anatomical and physiological properties of the insects' body parts will be tackled too. d. Biochemistry- is the study of chemical processes within and relating to living organisms. e. Genetics - is the study of genes, heredity, and variation in living organisms.[1][2] It is generally considered a field of biology, but it intersects frequently with many of the life sciences and is strongly linked with the study of information systems.
3. Briefly recall the experiment using insects as basis for the Abiogenesis Theory. In 1837, Andrew Crosse reported to the London electrical Society concerning the accidental spontaneous generation of life in the form of Acurus genus insects while he was conducting experiments on the formation of artificial crystals by means of prolonged exposure to weak electric current. Throughout numerous strict experiments under a wide variety of conditions utterly inimical to life as we know it, the insects continued to manifest. The great Michael Faraday also reported to the Royal Institute that he had replicated the experiment. Soon afterwards, all notice of this phenomenon ceased to be reported, and the matter has not been resolved since then. While examining with a microscope a thick plate of mica from Siberia, about 5 inches long and 3 inches wide, Sir David was surprised to observe the remains of minute animals, some the 70th of an inch, and others only the 150th of an inch in size. Some of these were enclosed in cavities, round which the films of mica were in optical contact. These acari were, of course, not fossil, but must have insinuated themselves through openings between the plates of mica, which afterwards closed over.

4. How do you know that such organisms are called insects? Give 5 examples of insects. * Insects' skeleton is found outside (exoskeleton), or upside down * Nerve cords extends along the lower side of the body and the heart lies above the alimentary canal. * They have no lungs and breath in the many microscopic holes in their body wall * Most insects are relatively small and ranging from about 0.25 to 330 mm in length and 0.5 to 300 mm in wingspread. * They are the only invertebrates with wings * They range in color from drab to brilliant * Insects are coldblooded creatures 1. Butterfly 2. Fruit Fly 3. Spider 4. Beetle 5. Grasshopper
5. What are the benefits of having insects around us? a. Medicine Insects also help us in discovering new medicines that helps in curing diseases in humans. For example, Blister Beetles can cause serious blistering to human skin, the chemical they secrete from their joints - called "Cantharidin" - is, ironically, used in some wart removal products. b. Agriculture "A great many insects are extremely valuable to humans, and society could not exist in its present form without them. By their pollinating activities, they make possible for the production of many agricultural crops, including orchard fruits, nuts, clovers, vegetables, and cotton; they provide us with honey, beeswax, silk, and other products for commercial value." - CA Triplehorn and NF Johnson, 2005 c. Food "Probably, 1000 or more species of insects in more than 370 genera and 90 families are or have been used for food somewhere in the world, especially in central and southern Africa, Asia, Australia, and Latin America. Food insects generally feed on either living or dead plant matter, and chemically protected species are avoided. termites, crickets, grasshoppers, locusts, beetles, ants, bee brood and moth larvae are frequently consumed insects. Although insects are high in protein, energy, and various vitamins and minerals, and can form 5 - 10% of the annual animal protein consumed by certain indigenous peoples. Western society essentially overlooks entomological cuisine." -P.J. Gullan and P.S. Cranston, 2010 "They serve as food for many birds, fish, and other beneficial animals." -- CA Triplehorn and NF Johnson, 2005 20 “‘All flying insects that walk on all fours are to be regarded as unclean by you. 21 There are, however, some flying insects that walk on all fours that you may eat: those that have jointed legs for hopping on the ground. 22 Of these you may eat any kind of locust, katydid, cricket or grasshopper.23 But all other flying insects that have four legs you are to regard as unclean." -Leviticus 11: 20-23 d. Biological Control "They perform valuable services as scavengers; They help keep harmful animals and plants in check." - CA Triplehorn and NF Johnson, 2005 e. Education and Research Insects can be helpful in our education too. One example is the entomology class. It adds to the knowledge of students about their course and insects can be used as their samples, subjects and topic for research. 6. What are the detrimental effects of having insects around us? Give particular insects that are detrimental. "A few insects are harmful and cause enormous losses each year in agricultural crops and stored products, and some insects transmit diseases that seriously affects the health of humans and animals." - CA Triplehorn and NF Johnson, 2005 Examples of these insects: 1. Locusts - eat agricultural plants plants 2. Caterpillars- eat plants and destroy fruit crops 3. Mosquitoes- causes dengue fever, West Nile disease and malaria 4. Tick- Babesiosis, Tick-borne encephalitis, Heartland virus disease, Lyme disease, and Rickettsial diseases, 5. Sandfly - Leishmaniasis

The Cure or the Disease?

...requires more cropland to produce.( Turk, J., & Bensel, T. 2011) We cannot simply do nothing. We have to find new and better ways to produce food. We cannot just search for short term benefit and not research what the future may bring. Genetically engineered food could give people enough food to eat but does come at too high a cost. Genetic Engineering of Food is not the way to cure world hunger but it is a way to stop or slow the growth of hunger. The question must be answered on several different levels. We see that the yeilds of the genetically engineered food is higher but at what cost. The cost of feeding people today could mean starving people tomorrow or worse contaminating them. Genetically engineered food yeild more crops but we must examine how it is done. The plant crops are resistant to insects. Through gentic means these crops are either unappealing to insects or at worse poison to them. Making it unappealing means these insects have to find alternative foods. This could mean that they will devestate other products and start a change in the way ecosystem. Poisoning the insect would cause a similar change. We have to consider that these insect maybe the food source for other insects and birds. What happens when they must seek new food sources? What happens when these insects are...

Anthropological Study on the Effect on Travel

...who have traveled there. I found that people who have traveled to Asian countries tend to have less food taboos than do those who have traveled to Europe. In fact, people who have traveled to Asia often could not cite one food that they refuse to eat. Everyone who has been to Europe on the other hand, could name at least one food that they personally consider to be inedible. I believe that the reason for this disparity can be found in the economic differences between the East and the West, and also, in the personal reasons people have for traveling to either Europe or Asia. Southeast Asians lack specific food types they refuse to eat. Besides the more conventional meats, i.e., beef, pork, poultry, they also eat dogs, cats, dingoes, and insects. An explanation for this can be traced to historical, ecological, and economical aspects of Southeast Asia. Marvin Harris, anthropologist and author of Good to Eat explores this specific field, and says the following about one of the unconventional meat eating trends in Southeast Asia. "Dog-eating cultures generally lack an abundance of...

Reduction of Bees and Its Effect on the Environment

...Introduction Bees are essential organisms of almost all of the world’s terrestrial ecosystems. Bees are flying insects that are in the same class as the ants and wasps among others. These small insects are responsible for pollination and wax production and honey production. They inhabit every continent except for a continent known as Antarctica. Importance of bees The insects are known for its role in pollinating a large percentage of the flowering plants. They participate in sexual reproduction that ensures cross pollination. This process ensures genetic diversity in the food chain that ensures that there is flow of energy from the primary producers to higher levels of consumers. Since green plants are source of food for other organisms, the reduction of one of the primary pollination agents, or even their possible disappearance, is of concern. The bees are on the decline due to various reasons that will be considered later on. I believe the there more pros than cons that can be obtained from the bees. Factors for reduction of bees The disappearance of bees is a very frightening scenario that is subject to an explanation. There various reasons as to why there has been a reduction of bees. This are explained as follows: The sustainability of agriculture is a healthy function of ecosystem services ensures as that it intensifies to meeting growing demands for food production. Climate change, however, may have major influence on the main ecosystem functions...

Genetically Modified Foods

...Collins February 26th, 2012 Genetically Modified Foods Genetically modified foods have increased the total harvest of many cash crops by eradicating the harm done by weeds and insects, and for the most part, this has been the single greatest benefit that GMOs have presented within the last decade. There are benefits being speculated and tested as of now to future speculation on what this science can bring us. There are other ways that GMOs are able to increase the overall bounty of a crops harvest, such as resisting dangerous diseases and being able to sustain the plant with less water or less nutrients. There have also been attempts to create plants resistant to more untamable forces of nature rather than pests, such as the temperature. There have been many speculations that cold-resistant crops, mainly corn and other fruits and vegetable, could be created by taking the DNA of cold-tolerant fish in the Arctic and splicing it with these foods. “An antifreeze gene from cold water fish has been introduced into plants such as tobacco and potato. With this antifreeze gene, these plants are able to tolerate cold temperatures that normally would kill unmodified seedlings,” (Whitman). One benefit in particular that has seemed to have caught the eye of retailers especially adding more nutritional benefits to foods, such as rice with built-in Vitamin A that can help prevent blindness in 100 million children suffering from Vitamin A deficiency.” (Sakko) The practice promises to increase...

Case Study 1: Monsanto Attempts to Balance Stakeholder Interests

...Case Study 1: Monsanto Attempts to Balance Stakeholder Interests This case involves Monsanto, the world’s largest seed company. This is no ordinary seed company, it specializes in the genetic manipulation of organisms, known as biotechnology. Weeds, insects, and drought have been a huge issue for farmers. Herbicides and pesticides were creators to keep pests off of plants, however, applying them proved to be expensive and time consuming. Monsanto answered this problem by creating seeds that contained the herbicide Roundup, which kills weeds without harming the crops themselves. These types of genetically modified (GM) seeds were just the beginning. Drought-tolerant seeds were also created for dry area such as Africa. Opponents of genetically modified crops have various reasons for believing that these products will have a negative effect on the people and insects that consume it. Monsanto has a history of unethical cultures that have had a negative effect on many stakeholders such as the environment, plants, animals and humans. The benefits of growing genetically modified seeds for crops do not seem to outweigh the negative consequences of using them. In an effort to manage the potential harm to plant and animal life from using products such as Roundup, Monsanto should adhere to the code of ethics and follow the EPA’s guidelines. “Ethical culture is acceptable behavior as defined by the company and industry” (Ferrell, Fraedrich, & Ferrell, p. 15).

Be ore specific. which are pests, diseases and natural environment changes, increase the agricultural yield, and reduce the pollution of the environment. There are some advantages of GM food on increasing the resistance of the natural risk. Firstly, it decreases the risk of the effect of insects. Most plants are the food of the insects, especially the crops which are important in people’s life. Crops do not have an effective means to protect them from insects, so farmers use pesticide to kill the insects that eat the crops. The seeds of GM food have their own resistance of insects, because scientist use the genes from other plants which release the smells that the insects hate or produce a natural bacterium called “Bacillus thuringiensis (BT)”Eva Schubert2015-11-07T08:41:00Put BT in brackets here. Then you can use BT alone for the rest of the essay. (Gatehouse, 2008). BT occurs in soil to produce a protein. When insects eat this protein, it destroys the digestive system of the insects and reduces the growth of the larva (Gatehouse, 2008). Secondly, it has resistance of the disease. “Viral disease” and “Fungal infection” are the two main diseases that affect the plants (Engel et al, 2002).

Bloodstain Pattern Analysis

...Insects are very location specific, and if insects are found on or within the remains that are not specific to that location, it can provide detail as to the place of death. Entomology can determine if a body has been moved or disturbed. This information can be critical to solving a crime. Bloodstain Pattern Analysis can be helpful in the determination of a crime scene provided that there is bloodstain present. It can determine whether something or somebody has been moved, and it can tell whether a crime scene has been contaminated through swipe patterns, and blood transfers. It can provide the direction of travel that the victim, or perpetrator moved, and offer a relative rate of speed. A perfect example of BPA offering information about the location is Sergeant...

Shade vs Sun Grown Coffee

...grown. The shaded coffee plants were resting places for migrating songbirds like warblers, orioles, wood thrushes and fly catchers. Thhese coffee plants were their food. Now there are fewer species of birds in the sun shaded coffee plants as compared to shade grown coffee plants. Many insects like orchids, amphibians and reptiles lived on shaded coffee plants but they cannot live on sun grown coffee plants. Stats show that sun coffee varieties has three times more production that than shaded coffee. But many chemicals as fertilizers, insecticides, herbicides and fungicides are used for their growth. These plants have very small roots which increases erosion. It is true that most of the worlds’ coffee produce is now from sun grown but that was not always the case. Initially most of the produce was shade grown. Most of the varieties of coffee were traditionally intolerant of direct sunlight. Trees provided the proper environment like organic wastes and moisture for proper growth. Nitrogen-fixing legumes are also present in this enviroemnt which convert nitrogen in usable forms. This environment has many natural advantages like it keeps the earth cool, creates clouds for rainfall, controls insects and provide them living place. Many studies have also revealed that shade based coffee farms have less birds and wild life diversity than sun based farms. The presence of trees and shaded coffee plants on very steep mountainous landscapes in high-rainfall areas helps to stabilize...

Changing Ecosystems Chapter 6 Summary

...Summary of chapter 6 We live in a world that has increasingly forgotten the powerful influence our environment plays in our daily lives. If we come to the conclusion that a plant or animal is inconvenient to us we pursue for its destruction or removal. Changing ecosystems for any benefit must be heavily considered with the knowledge of the current benefit the habitat already serves as well as its history. Interspecific and intraspecific relationships weave a web, so to speak, of any ecosystem that can easily fall apart if one strand is broken. Weed eliminating chemicals are largely used without any thought of later consequence. An example of this method was implemented for sage brush lands of the rocky mountains. Citizens wanted to see the sage land destroyed to give rise to a grassland habitat. This area contains high plains from the west that connects to the low slopes of mountains. The climate is harsh due to the location with high winds, heavy annual snowfall, and intense summer heat. The plants of this area took many long years learning how to adapt to this and eventually the sage took over. The physical characteristics of the sage allowed it to not only benefit the land but also the animals residing in it. The sage grouse relies on the sage bush for their nesting...

Importance of Adopting Policies of CSR Codes of business standards are basic to the organization of CSR policies which are necessary to sustain and create an ethical culture within an organization (Erwin, 2011). The actions and conduct of employees of an organization are governed by the codes of conduct that ultimately affect the organizational culture (Erwin, 2011, p.536). This code of business standards promote ethical business practices and help avoid legal consequences. This commitment to social responsibility leads to reputational benefits as it shows a symbol of responsiveness and engagement of CSR by the organization (Erwin, 2011, p. 536). Other benefits of adopting codes of business standards are improved customer relations, product differentiation, reduced insurance premiums and risk management (Erwin, 2011, p. 536). Addressing CSR issues, organizations are becoming tempting organizations of all business showing commitment to ethical standards and enhancement, as well as, financial performance (Erwin, 2011).
