Fruit Flies Research Paper

Throughout this experiment a number of random and procedural errors were apparent; these errors could have affected the results of the experiment in a number of ways. One experimental error that occurred during the experiment was that some flies became stuck in the food source and died. The main cause of this was the fact that the fly vials were stood up (vertically) before the flies had fully recovered from the anaesthetic. This could be overcome in future experiments by ensuring that the vials are kept horizontal until all of the flies fully recover from the anaesthetic.

Drosophila melanogaster is a small, common fly found near unripe and rotted fruit. It has been in use for over a century to study genetics. Thomas Hunt Morgan was the best biologist studying Drosophila early in the 1900’s. Morgan was the first to discover sex-linkage and genetic recombination, which placed the small fly in the forefront of genetic research. Scientists have used Drosophila for many reasons. For one they are very easy to maintain, breed, anesthetize, and kill with little equipment. They are also very small and it is easy to distinguish males vs females and sexually mature flies and virgins. At lastly, the flies have a very short two week life span. On days 2-7 of their life

With the presence of natural selection (fly paper hanging from top of cage) posing a larger threat to the wild flies b/c they can fly better, this will allow vestigial flies to prosper better.

Introduction: The intention of this lab was to gain a better understanding of Mendelian genetics and inheritance patterns of the drosophila fruit fly. This was tasked through inspecting phenotypes present in the dihybrid crosses performed on the flies. An experimental virtual fly lab assignment was also used to analyze the inheritance patterns. Specifically, the purpose of our drosophila crosses is to establish which phenotypes are dominant/recessive, if the traits are inherited through autosome or sex chromosomes and whether independent assortment or linkage is responsible for the expressed traits.

Moss might be used were it not that it directly breeds a swarm of flies.” Superior conditions, indeed.

California grizzlies had been around earth for centuries before humans invaded their territory. In the state of California, “some [California grizzlies] grew to a formidable height of 8 feet and weighed 2,000 pounds, according to a history of California written in 1898”, which made them targets for the various resources they could provide naturally (Staff). When miners came to California to harvest the gold, they began to see the grizzlies as a threat. In “less than 75 years after the discovery of gold… every grizzly in California had been tracked down and killed” making it extinct shortly after (Staff). Grizzlies in California were hunted and killed because they were seen as dangerous and hunters would harvest them for their resource of warm

Even when subjected to these temperatures, some bed bugs and eggs simply will not die. However, chemical only treatments alone, such as DIY bug bombs also fail. That is why a pesticide combined with either extreme heat or extreme cold is the best option to give the bugs and eggs a double-whammy that they are less likely to survive.

3. Get rid of colonies. Colonies of aphids can be snipped off. If you find aphids in groups or colonies, snip off the part of the plant that contain the colonies and kill the bugs. This will not get rid of all the bugs, will it will help to lessen the additional breeding.

Did you know that you can catch fruit flies WITHOUT our Bait Booster? Yes it is true, bananas alone will do a good job of luring the little critters into eek-o. You just need two extra things, patience and diligence. Patience because it can take up to a day for fruit to start the fermentation process which releases into the air odor signals telling fruit flies that their preferred food source is nearby. And diligence because if you don’t dispose of or empty your trap in a timely manner, the next generation of fruit flies will start to emerge, which can be disconcerting to say the least.

Heavy feeding by the whitefly causes the death of numerous plants, or degradation in growth of older plants, because of the loss of sap. “When adult and immature whiteflies feed, they excrete honeydew, a sticky excretory waste that is composed largely of plant sugars. The honeydew can stick cotton lint together, making it more difficult to gin and therefore reducing its value. Sooty mold grows on honeydew-covered substrates, obscuring the leaf and reducing photosynthesis, and reducing fruit quality grade” (USDA 2016). By noticing the harmful effects that the whitefly has on the environment, many actions are being made to prevent the spread of further

METHODS: In this experiment, the instructor provided us with 30 ebony individuals and 20 wild type individuals. In order to get an exact amount of each type, we anesthetized the flies and counted them off by gently using a fine point paint brush. Then all 50 Drosophila were put into a population cage which had a lid that had six holes for the centrifuge tubes. Two food tubes and four clean, empty tubes were added on the first day. Each food tube consisted of half a cup full of food mixed with 6-7 milliliters of water. This was the fly medium. The food should turn blue once the water is added. Each tube was labeled with a number and with the date. Every two to three days we added one more food tube until all 6 tubes contained the fly medium. After all 6 tubes were filled, the following days after we exchanged the first food tube with a new food tube. At the end of the experiment, we fed the flies with a total of 8 food tubes. Then the flies were anesthetized, again. At the end of this four week lab, the number of living ebony and wild

Use Insecticides: If you’re unsure what type of insecticide to use, talk with an exterminator. Many will recommend the bee control

“The trap will remain closed for eight to ten days. when it reopens , all that is left of the ant is an exoskeleton , which the wind soon blows away.” The fly trap will get as many insects and then it would shout for at least 1 week closed. That so weird that a plant gets to eat insects and move around .

I whipped out my laptop, Googled fruit fly traps, selected the most promising-looking trap to create and studied on how to craft it. Vinegar, check, dish soap, check, paper cone, check, bait, check. I had everything needed to make a fruit fly vinegar trap. I made several traps

First, if you have the money to spend, you may call a professional to do it for you. A pest control company can treat your mattress, carpet, furniture, and sheets to get rid of the bedbugs. If the bedbugs are confined in your mattress, inspect it to see the extent of the infestation. If there are too many cracks, holes, or tears, you have to throw this out. Bedbugs love to live in those crevices. If the infestation is still manageable, you can get rid of bedbugs by following these methods.
