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.
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 ...
Effective biocontrol agents include predatory fish that feed on mosquito larvae such as mosquitofish (Gambusia affinis) and some cyprinids (carps and minnows) and killifish. Tilapia also consume mosquito larvae. [38] Direct introduction of tilapia and mosquitofish into ecosystems around the world have had disastrous consequences. [39]
Some species of bee are beneficial as pollinators, although generally only efficient at pollinating plants from the same area of origin, facilitating propagation and fruit production for many plants. This group includes not only honeybees, but also many other kinds of bees that are more efficient at pollinating plants native to their region.
The scientific journal Entomophaga was the official journal of the organization, until superseded by BioControl. In 1971, Global IOBC was established and the former IOBC became the West Palearctic Regional Section. There are six regional sections world-wide: Afrotropical [9] Asia and Pacific [10] East Palearctic [11] Nearctic [12] Neotropical [13]
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. They are obtained from organisms including plants, bacteria and other microbes, fungi, nematodes, etc.
More than a thousand papers have been published on Trichogramma species, and they are the most used biological control agents in the world. [ 6 ] Trichogramma spp. are also of interest in neuroscience research, having fewer than 10,000 neurons , approaching the theoretical lower limit of the size of an insect brain, yet exhibiting complex ...
Over 1.5 million living animal species have been described—of which around 1 million are insects—but it has been estimated there are over 7 million in total. Animals range in size from 8.5 millionths of a metre to 33.6 metres (110 ft) long and have complex interactions with each other and their environments, forming intricate food webs .
