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.
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.
Ladybirds (also known as lady bugs in North America) are a beneficial insect commonly sold for biological control of aphids.. Beneficial insects (sometimes called beneficial bugs) are any of a number of species of insects that perform valued services like pollination and pest control.
Cultural controls include keeping an area free of conducive conditions by removing waste or diseased plants, flooding, sanding, and the use of disease-resistant crop varieties. [19] Biological controls are numerous. They include: conservation of natural predators or augmentation of natural predators, sterile insect technique (SIT). [26]
A Hygieostatic Bat Roost, custom-built to house bats for biocontrol of mosquitos. Biological pest control, or "biocontrol", is the use of the natural enemies of pests like mosquitoes to manage the pest's populations. There are several types of biocontrol, including the direct introduction of parasites, pathogens, and predators to target mosquitoes.
Pseudomonas fluorescens has multiple flagella, an extremely versatile metabolism, and can be found in the soil and in water.It is an obligate aerobe, but certain strains are capable of using nitrate instead of oxygen as a final electron acceptor during cellular respiration.
The most common species, S. maltophilia, is very versatile and can be beneficial for plant growth and health, can be used in agriculture, biocontrol, bioremediation and phytoremediation strategies as well as the production of biomolecules of economic value. [3]
One example of a biocontrol program that resulted in ecological damage occurred in North America, where a parasitoid of butterflies was introduced to control gypsy moth and browntail moth. This parasitoid is capable of utilizing many butterfly host species, and likely resulted in the decline and extirpation of several native silk moth species.
