Biological control or biocontrol is a method of controlling pests, whether pest animals such as insects and mites, weeds, or pathogens affecting animals or plants by using other organisms. [1] It relies on predation , parasitism , herbivory , or other natural mechanisms, but typically also involves an active human management role.
Mosquito control is a vital public-health practice throughout the world and especially in the tropics because mosquitoes spread many diseases, such as malaria and the Zika virus. Mosquito-control operations are targeted to multiple problems: Nuisance mosquitoes bother people around homes or in parks and recreational areas;
Biological pollution (impacts or bio pollution) is the impact of humanity's actions on the quality of aquatic and terrestrial environment.Specifically, biological pollution is the introduction of non-indigenous and invasive species, [1] otherwise known as Invasive Alien Species (IAS).
For example, larvicides can be used in mosquito breeding zones; insecticides can be applied to house walls or bed nets, and use of personal repellents can reduce incidence of insect bites and thus infection. The use of pesticides for vector control is promoted by the World Health Organization (WHO) and has proven to be highly effective. [7]
A biological hazard, or biohazard, is a biological substance that poses a threat (or is a hazard) to the health of living organisms, primarily humans. This could include a sample of a microorganism, virus or toxin that can adversely affect human health. A biohazard could also be a substance harmful to other living beings. [a]
Human disturbance of ecology ecological systems, particularly the development of monoculture and the movement of species tends to stimulate pest problems by reducing biodiversity which usually has natural controls that keep pest populations in line. Biological pest control does not seek to eradicate pests, but to keep them to economically ...
A Biopesticide is a biological substance or organism that damages, kills, or repels organisms seens as pests. Biological pest management intervention involves predatory, parasitic, or chemical relationships.
A microbiologist working on the reconstructed virus of the 1918 Spanish Flu, using a fume hood for biocontainment. [1]Biosecurity refers to measures aimed at preventing the introduction or spread of harmful organisms (e.g. viruses, bacteria, plants, animals etc.) intentionally or unintentionally outside their native range or within new environments.
