Biological pest control

There has been considerable concern over the role of climate change in promoting the emergence of new nematode diseases and in changing the distribution of existing ones. As the global warming increases, pests and diseases from low latitude regions, where they are much more prevalent may be introduced at higher latitudes. Recent developments in experimental and modeling techniques facilitate climate change impact assessment on nematode diseases. Pine wood nematode, bBursaphelenchus xylophilus, severity

Impacts of Agricutlure on the Environemnt The negative environmental effects of agriculture – water and air pollution, loss of habitats and biodiversity, greenhouse gas emissions, and nutrient losses – have received major attention and continue to persist. Environmental concerns arise from many agricultural activities and sources including concentrated livestock production, pesticide and chemical use, deforestation, drainage of wetlands, soil erosion from cropland, and the use of fragile lands

the most important element for agricultural ecosystems. Healthy soil comes with beneficial microbes and insects. Unfortunately, these are often killed off by the abuse of pesticides. Healthy soil can produce strong crops that are less vulnerable to pests. Damaged soils often need strong fertilizers application to produce a high amount of crops. Soil quality can be amplified in many ways, including leaving crop remainders in the field after harvest and adding composted plant material (Union of Concerned

1986). Therefore, it is essential that this crop remains prevalent in today’s agricultural world. Unfortunately, Vigna unguiculata faces a large amount of predation from multiple species, one of which is the bean beetle Callosobruchus maculatus. This pest, along with others, leads to crop failure and a complete loss in the resource for potentially an entire agricultural season. Callosobruchus maculatus, a plant-feeding insect, compromises the integrity of Vigna unguiculata populations by using either

In high school we have learned about that gene is the basic unit to control biological traits, genetic information is recorded biological procreation. Different information recorded in different genes, gene can be changed by modifying some or all of the features of an organism. After entering the university, after the completion of the study a semester general biology, although not yet talked about the genetic aspects of the content, but for the interest in this part of the simple read a bit. I learned

Dual Use Dilemma According to the U.S. National Science Advisory Board for Biosecurity, (NSABB) “dual use” research includes “life sciences research with legitimate scientific purpose that can be misused to pose a biological threat to public health and/or national security.” (Holohan, n.d.) The dual-use research dilemma refers to the challenge of producing and publishing research with the intent to improve public or animal health or to increase agricultural productivity, which, can be used for

THESIS STATEMENT: Research suggests that organic farming is a sustainable system of agriculture because it builds a toxin free biologically diverse ecosystem, controls soil erosion, and enhances the quality of air and water by reducing the hazardous chemicals.

A major measure of biological fitness in a population is the fecundity, or reproductive success rate, of female organisms (Berger et al, 2008). For insects in particular many factors influence the number of eggs produced during the lifetime of a female. One key factor in insect reproduction is the ambient environmental temperature. Insects are ectothermic and therefore rely on their environment to provide the heat needed to carry out normal reproductive functions. Ambient heat dependence for insects

the plants. Some if the provisioning services are energy, seafood, and transportation. Some of the regulating services are : flood prevention, climate regulation, erosion control, and control of pests. Some of the cultural services are : educational, recreational, and spiritual. Some of the supporting services are : biological diversity, nutrient recycling, and primary productivity. The things that humans are doing to destroy this ecosystem is that they pollute the ocean this is true because

“A Ratty Western World” When searching for “rats” on the internet; pests control services, campaigns of eradicating rodents, media reports on rat infestation and diseases, outnumbers the various other search results. This widespread negative image of the rat, according to Edelman (2002), can be traced back historically in the Western world. However, after rat-sporting became prohibited by English law in 1870s, the Western culture began to interact with the animal differently (Edelman 2002).By the
