Biological pest control

As the world’s population continues to grow, there is a mounting urgency regarding the lack of long-term sustainability of modern agricultural systems. The prevalence of chemical fertilizers, pesticides and monocultures reflect food production systems that not only require constant human intervention, but also lack internal regulation. To address these economic and environmental issues, one key strategy would be to enhance the biodiversity in agroecosystems in order to model the homeostasis present

types of chemical, biological, radioactive, nuclear and explosive weapons. Often times, which category depends on factors such as knowledge of the materials being utilized, funding and research capabilities, the ability of acquiring a weapon from an outside source or what the desired end state of the mission may be. In the case of the Rajneesh, that weapon was biological. In 1984, Rajneesh’s cult used a form of Salmonella to contaminate restaurants (Forest 2012). Biological threats, according

of synthetic pesticides, which is classical biological control. This is the practice of importing, and releasing for establishment, natural enemies to control an introduced pest. Classical biological control is long lasting and inexpensive. Other than the initial costs of collection, importation, and rearing, little expense is needed. When a natural enemy is successfully established it rarely requires additional input and it continues to kill the pest with no direct help from humans and at no

When an exotic pest enters an area and finds a suitable host tree, the lack of evolutionary resistance to the pest in that host tree, along with the lack of natural predators for the pest in that area, often creates a deadly combination (Foster et al. 2014). The hemlock woolly adelgid (HWA, Adeleges tsugae) is one such exotic pest that has had devastating consequences in eastern North America in recent years. HWA is a small adelgid native to Japan that was first found on ornamental Japanese hemlocks

slender. These eggshells become so thin that whenever the mother bird would lie on the egg waiting for it to hatch, the eggs would break. Thus, the predatory bird population had no means of increasing, since their reproduction was not successful. Biological magnification had a large role to play in the decrease of the predatory bird population. Spraying of DDT on vegetation led to contamination of the prey populations such as fish. These prey started building large concentrations of DDT within their

It was the result of nearly a decade of grassroots activism and a new American conscientiousness about environmental issues. The impetus for much of this activism can be identified in a book

Quarantine is forced isolation of a diseased organism to control the spread of infectious diseases (viruses, bacteria) establishing in Australia, as they can harm the

Without controlling these pests the New Zealand native bush and native species would be decimated. 1080 is a very effective poison and it is reported by The Department of Conservation (DOC) that 1080 kills approximately 98%
