Evolution of Western Corn Rootworm Population Evolution of Western Corn Rootworm Population The aim of the research study was to find out how the western corn rootworm can thrive in fields that alternate between plantation of corn and soybeans. In the 20th century, there was decline in crop rotation in the U.S due to the use of fertilizers and insecticides. However, insecticides began to fail in the 1950s and crop rotation was introduced to kill worms that fed on corn. This method became effective for long but some year’s later rootworm damage was seen in the crop-rotated fields. The researchers found out that the rootworm had developed the ability to survive in the chemical warfare with soybeans by producing enzyme inhibitors that enabled them digest proteins in the soybeans leaves.
The characteristic that has allowed some Western corn root worm populations to become resistant to corn - soybean- corn rotation is that they produce higher levels of special class proteinases (cathepsin-L) that respond to soybeans defenses (Yates, 2012).
Darwin’s theory of natural selection states that evolutionary change occurs when individuals produce variations in each generation and differential ways of survival by combining these variable characters. Individuals with variable characteristics, which increase their chances of survival, will have more opportunities to reproduce and their offspring will benefit from these advantageous characteristics. Similar to this theory, the western corn rootworm has evolved to produce enzymes in their gut that has enabled them to become resistant to corn-soybean-corn rotation. The enzymes inhibitors enables them to survive for two to three days in the soybeans fields which is enough for some of rootworms to lay eggs, when corns are planted in the same fields the rootworm larvae feeds on the corn roots.
The modern view of evolution as a change in allele frequencies defines evolution as not only the development of new species from older ones but also the small changes within species from generation to generation-over long periods. Similarly, the western corn rootworm has been able to produce special class proteinases over long period of time, these small changes have enabled them to survive on soybean fields.

Western Civilization. History and Background of Evolution

...?Western Civilization History of Evolution The documentation on the history of evolution by Charles Darwin talks about the origin of genus using natural choice ways. The works by Darwin focused on evolution and became popular in the year 1859 after the publishing of his works. Darwin always had an interest in nature from his early childhood years. In the years between 1823 and 1913, Russell Wallace too discovered this idea of natural choice (Kemp, p.12). Darwin’s book “The origin of species” introduced the scientific theory that stated that the people did evolve through the ages through a process of natural choice. Background of evolution In the year...

Corn production

...being studied… (3) empirically invariant with respect to their classificatory criterion… (4) reflect the degree of availability of data referring to this unit… and (5) decisions to select and classify units of analysis should be based on standardised and repeatable procedures. The social issue that I have chosen is the issue of bio-ethanol production and agro-fuels – a contentious issue debated upon in an age of energy vulnerability and land shortages. The proponents of agro-fuels laud initiatives by the US government to embark on massive corn ethanol production, chiefly to decrease reliance on fossil fuels. On the other hand, its opponents argue that there are risks to small-farmers in rural places of production and can...

Corn farmers

...? Corn Farmers Corn Farmers The federal subsidy has ended in and farmers are feeling the pinch because the ethanol production has plummeted. Ethanol was used in the place of gasoline by blending it in certain proportion that has raised the demand of ethanol. It is known that gasoline has a huge demand. To reduce gasoline consumption, the government has provided subsidy to blenders of the ethanol. The withdrawal of subsidy now makes blending costly to that extent. Corn is a raw material for producing ethanol and thus, it suffers lesser demand from the ethanol producers. As per the law of demand and supply of economics, lesser demand of corn will push the price of...

...? Could Galinat’s scenario for corn be applied to the domestication of wheat? Explain your answer.  According to Galinat, the domestication of corn involved the addition of the number of spikelets in teosinte (572). Teosinte and Tripsacum both had only two spikelets or two rows of seeds and due to cultivation practices that the wise lady devised, some mutants of four spikelets were produced, although the best mutation that she hypothetically discovered was one with “eight male rows,” which she called “the breakthrough advance to create humanity’s maize” (572). This eventually led to the evolution of modern maize. The hunters then began domesticating this maize as society transformed into...

...of corn plants from the damages of insects as well as generating greater productivity along with quality grains for the environment (Syngenta, 2013). Potential Impact of Bt Corn On Individual Agricultural Ecosystem After acquiring a brief idea about the transformation of corn plants with Bt gene, it has been apparently observed that Bt-corn impose considerable impact upon individual agricultural ecosystem. In this modern context, the impact of Bt-corn on the agricultural ecosystem can be identified on the basis of the study that was propounded by the scientists of various nations regarding assessment of risks on the population of monarch...

Industrial Corn

...Industrial Corn Currently, corn is the most widely planted cereal in the world and seemingly, it will continue to dominate the food and industrial markets. This is hinted by the actions like those of the US Congress of subsidizing corn by the bushel therefore ensuring that its dominance is unchallenged. The boom in corn production is a result of production of corn for industrial purposes instead of just producing what is enough for normal human consumption. This is also called industrial corn. These surpluses have allowed corn to find a variety of uses, for example, making of biofuel and as livestock feed. Although the...

This book explores how modern human beings acquire, produce and even prepare food. Too the book tries to uncover the operations that concern the major facets of food system. Pollan too examines the local food movement, the organic movement and the importance of hunting and gathering. He tries to find out the connections between different systems and also speculates on the importance the different methods for getting food. In this book, Pollan seems to wax philosophical on the implications of different aspects of food. For instance, other than taking us as the caretakers of corn...

Corn Lab Report

...Corn Kernel Color Lab Report Corn Kernel Color Lab Report Introduction The primary aim of this laboratory exercise was to investigate the inheritance of corn kernel color (blue vs. yellow) and whether it is determined by only two alleles. Variations in the color of corn kernels normally follow the principles of Mendelian genetics and are widely known to be controlled by particular gene pairs (alleles). According to Ford (2000), the gene combinations (genotype) of the kernels can be deduced by simply observing their appearance (phenotype). Methods The simulated exercise involved monohybrid crossing of corn by breeding a true breed blue...
