Advantages of Pheromone Application in Controlling Pests Essay

Although insecticides aren’t sprayed directly to get rid of bees, the plants that bees have to pollinate are more likely farm crops instead of wild flowers found in their natural habitats. Some of the problems that chemicals present include reduced physical capabilities, a gradual decline in function, and loss of a queen bee. Because bees were being treated for the chemicals, their natural defense systems were impaired. Bees that were sick or infected stayed in the hive with the colony for longer periods of time. When the hive got too tainted, the queen would leave and the bees would have no eggs for future bees. The colony would either have to find a new queen or wait for an eventual end of the

PEST analysis will be able to be utilized to help detect trends in the external environment that will eventually discover their method into the competitive environment. It gives a relation between the general and competitive environments in that weak signals in the general

Migita and Moriyama (2004) declare that in unknown environments, animal behaves inappropriately by expressing their innate or learned behavioral patterns. A. vulgare are often found constantly moving around the edge of the Petri dish because the environment is unfamiliar and appears as an obstacle (Migita and Moriyama 2004). One observation of pill bug’s movement is when they follow each other. Males can detect females through distance chemical communication (Beauché and Richard 2013). Due to aggregation pheromone, the A. vulgare are attracted to each other.

-Arthropods use pheromones, this includes sowbugs and cockroaches. Chemical signals are picked up by antennae.

The gypsy moth (Lymantria dispar) is a highly disruptive species that can, and has played a distinctive role in the lives of many organisms. Included in these organisms are various deciduous trees and shrubs, wildlife species that share the same environment, and even humans. The gypsy moth destroys the beauty of woodlands via defoliation, alters ecosystems and wildlife habitats, and disrupts our own lives. It should therefore come as no surprise that the U.S. Department of Agriculture and many other agencies have taken huge steps to help diminish populations of this small, yet persistent species. In an effort to control these overwhelming populations, five chemical control agents have

In this experiment, we tested three different environments, soil, sand, and a leafy mixture to see which one a pill bug would prefer the most. Originally, we believed that the pill bug would find the leafy substance to be most favorable. Five pill bugs and then a single pill bug was placed in the center so that it could select one of the substrates. The data collected at the end of the experiment opposed our original hypothesis as we discovered that the most favored environment was the soil. This finding could correlate with the dark color of the soil closely matching the color of the pill bug or the moisture in the soil.

This experiment was constructed to determine which type of writing utensil the termites were most attracted to and why. The experiment was performed by placing two separate circles (one red papermate and one lead pencil) on a piece of paper to see what line is favored by the termite. The termite was placed on the lead pencil path first, and then on the red papermate pen path to count how many seconds the termite remained on or followed the pathway. The termite stayed on the red papermate line for a much more significant time than on the lead pencil line. “The presence of insect pheromones that chemically control the behavior of highly specialized social insect

In the early 1940’s, a new technology emerged that was able to successfully combat crop-damaging and disease-carrying insects. A new age of synthetic chemical pesticides use arose. After their impressive success in fighting deadly insect-borne diseases during World War II, pesticides were used widely to combat insect pests for agriculture and public health. Few people challenged the benefits of the new scientific and technological products and many embraced pesticide use with enthusiasm. Despite its success, doubts about pesticide use began to appear a decade later in the 1950’s, when the government began a vigorous pesticide campaign across the country against insect pests. Scientists began reporting heavy losses of avian and

One aspect of our results was close to having a significant difference. There was no difference among the frequency of male antennal grooming between the three different B. dubia densities with pheromones, but the data was close to being statistically significant (p= 0.051), and we think that with more refined methods, and a better understanding of B. dubia social interactions that future data may be statistically significant. We thought that antennal activity would be the most important aspect of cockroach behavior when it came to the spread of disease and social interactions, but our data did not support our hypothesis. We made many observations, that we did not quantify, that demonstrated much more active behavior in the presence of pheromones. These behaviors, including males approaching the cotton ball with the female pheromones and the males sparring with each other, were much more common in the

However, pesticides are used to control pests, which include insects, mice and other animals, unwanted plants (weeds), fungi, or microorganisms like bacteria and viruses. Often misunderstood to refer only to the insecticides, the term pesticide also applies to herbicides (that control weeds), fungicides (that control fungi), and substances used to control other pests. In addition, because many pests tend to travel between farms, resistance to pesticides can evolve at an inefficient rate. Farmers can increase the economic efficiency of chemical use by adapting integrated pest and resistance management practices, such as rotating crops and pesticides, reducing reliance on a single pesticide, adjusting planting and harvesting dates, scouting fields, and using more benign, and biological control

Carson clarifies that “the sprays, dust, and aerosols are now applied almost universally to farms, gardens, forests, and homes-nonselective chemicals that have the power to kill every insect, the “good” and the “bad”.” In contemporary world today many people use these mankind chemicals without understanding the effects of nature. For example, the reproduction of bees are dropping traumatically because of the pesticides effects on the insects. According to CNN “How Pesticides are killing the bees “Recent data published in science, Nature and other un journals show that bees are dying from some pesticides that are found in our food supply.” The damaged the chemicals are doing to the bees have worries many scientists. The New York Times wrote, pesticide linked to honeybee deaths, “a group of pesticide believed to contribute to mass deaths of honeybees.” Another example of the harmful chemicals affecting the good insects are by destroying favorable insects such as lady bugs and butterflies, which are another great alternative way to pollinate flower. These beneficial insects are very important for human wellbeing; therefore, we should minimize the use of

This suggests that the roadsides was once beautiful and bloomed with healthy and lively vegetation; however, they are now destroyed due to the use of pesticides. From these examples, it can be shown that even though pesticide is beneficial, its deadly effects outweigh its benefits; in addition, it is a dangerous substances to the environment, organisms, and even human.

America the Beautiful! So why are we destroying it everyday with the use of pesticides? It has been proven that pesticides have affects on it's surrounding, although made to improve earths resources, they typically take there negative effect on the environment in time. Pesticides affect more than the environment; they also affect the animals and humans living in the environment. There are alternative, to this major problem but, we as the caretakers of earth must act fast. In the following paper I'm going to share with you what pesticides are. I'll tell you why they are not safe to use and some of the affects of pesticides. Last, I will talk about some new alternatives there are

In the book 'Silent spring ' written by Rachael Carson we find a picture of Carson 's deep concept about the connection between nature’s equilibrium and the web of life that has been ruined by the uncontrolled use of insecticides which in turn affected the healthy livelihood of this earth’s creatures. Furthermore, she tells the readers of substitute techniques of achieving the same ends. The title of the book is enough to make us understand that it was a hint of a spring season with no bird songs painting our atmosphere meaning that all birds had vanished due to misuse of pesticides.
