Pillbug Case Study Answers

There is always opposition to pesticides because of the harm that it can cause on the environment and the animals alike. Pesticides though have saved a lot of hard work for farmers over the past couple of decades because it does all the dirty work, for example, the killing of weeds and other pests. Pesticides have also saved a lot of money for farmers by preventing pests from damaging crops or taking the nutrients and water supply away from crops. (Whitford, 7) In the future we need to start to find less toxic ways to prevent pests from attacking the crops and vegetation. This would prevent a lot of the other costs associated with pesticides for example, health costs for farmers that are exposed to the toxic chemicals or the killing of the habitats in the surrounding areas.

Although they may be small in size, they have had a significant impact on human activities in terms of agricultural production and in the same way it can be observed that human activities have impacted this species in terms of optimal conditions for reproduction and growth. Globally, invasive insects cost an estimated $2. 1 billion in forest damage and $13 billion in loss of crop depending on how detrimental the species is but nonetheless, a species such as the love bug demonstrates that even nuisances can provides benefits amide the costly

The overall purpose of this investigation was to determine the effects of different types of environments on pill bug attractancy. Pill bugs were exposed to 2 different environments (sugar and water). The attractancy was observed and recorded in a raw data table. A research hypothesis was formulated that the sugar would work as the best attractant for pill bugs. Sugar had the greatest impact of the two environments used because it attracted 8/9 ants.

A population increase

In “The Six-Legged Meat of the Future”, authors Marcel Dicke and Arnold Van Huis, believe the insects are going to become the new meat in place of pork, beef, or chicken. Dicke and Van Huis have researched the experiments and foods in the Netherlands to advocate their belief. These “insects are high in protein, B vitamins and minerals like iron and zinc, and they’re low in fat”(Dicke and Van Huis, para. 2). Also, most people believe that insects can have poisons, however, “less than 0.5% of all known insect species are harmful” (Dicke and Van Huis, para. 6).

In the recent years, there has been an increase of invasive species in Florida such as the Burmese phyton. These reptiles are initially from Southeast Asia but due to the irresponsibility of some pet owners, they have started to invade Florida specifically in the Everglades. So far, an alarming amount counting in the hundreds have been captured in the Everglades National Park, showing how important it is to keep their population under control and from wreaking havoc. Known for consuming birds and small mammals, they show an immense effect on the local ecosystem. Authorities have hired hunters and even started annual manhunt events for these pests.

For example, beginning with the population of America, up until 1860, it was 31,000,000 people, and in the thirty years, there was a “sudden” 92,000,000 (251 TAE)! As stated in Chapter 7, it was not “huge” population growth, but this was evidence that the population

We took a large net and set it vertically in the water, and then somebody got in the creek and kicked up sediment into the net. After doing this a few times, we collected all of the creatures off of the net and into an ice cube tray. We then examined the creatures and noted the variety (or lack thereof) of the creatures. The larger the variety in the species of the creek, the healthier the creek is. We noticed several species of fly larvae such as stone fly larvae and caddis fly larvae. We also noted a few worms.

In this experiment, we are testing whether or not the Isopods' have more of a preference for an environment with syrup or with water. The alternative hypothesis we devised is that if the Isopods are placed in between a syrup and a water chamber, then they will go towards the syrup chamber. This is believed because we believe the Isopods may have an attraction to the sweet scent and taste of the syrup. My group and I observed 10 pillbugs behavior over the span of 5 minutes, recording the number of pill bugs found in each chamber every 30 seconds. We fail to reject the null hypothesis because the chi squared value is 3.6 which is less than 3.84 (critical value at .05).

The bess beetle lives in damp rotten wood, which also serves as their source of food. Bess beetles can lift up to 100 times its weight. There are nearly 500 species of beetles in the family Passalidae. The Bessbugs are found in Eastern and south-central North America. The Bessbug Beetle ranges from 1.2 inches to 1.6 inches.

By doing this some of the consumers can be easy to catch a new disease or get even sickly with the pesticide and

Although China’s land is not as big as Russia or Canada, but their number of people make up more than two countries. Overpopulation in China is one of the serious problems that the world is facing because it brings unemployment, exhaustion of natural resources and also environmental at pollution. Why is China’s population more than other country, because

Pesticides and How it Works Abstract: A pest is "a plant or creature unfavorable to people or human concerns". Pesticide is Chemical or natural substance intended to slaughter or retard the development of pests that harm or meddle with the development of products, bushes, trees, timber and other vegetation coveted by people. Keywords: Antimicrobials, Antimicrobials, Herbicides Introduction:

Population size may vary as individuals are born or immigrate and other may die or emigrate. One model of population growth is the exponential Population Growth; which is the accelerating increase that occurs when growth is unlimited. It predicts that the larger the population is, the faster it grows. This growth model is normally for short lived organisms due to the introduction of a new or underexploited environment. Next, there is the Logistic Population Growth.

As expressed through this exploration, the exponential growth model is more simple and easy to illustrate, yet real life situations regarding population growth is more complex; as a result, the logistic growth model is considered more
