What is biocontrol Inundative?
Inundative biocontrol – a large quantity of natural enemies are periodically applied to reduce weed populations. Biopesticides – the application of formulations containing whole natural enemies (generally a pathogen that causes disease in a weed) or toxic components of natural enemies to reduce the weed population.
What are two examples of biological controls?
This guide emphasizes the biological control of insects but biological control of weeds and plant diseases is also included. Natural enemies of insect pests, also known as biological control agents, include predators, parasitoids, and pathogens. Biological control of weeds includes insects and pathogens.
What are three biological pest control methods?
There are three basic biological pest control strategies: importation (classical biological control), augmentation and conservation.
- Combined use of parasitoids and pathogens.
What are biological control methods?
Biological control or biocontrol is a method of controlling pests such as insects, mites, weeds and plant diseases using other organisms. It relies on predation, parasitism, herbivory, or other natural mechanisms, but typically also involves an active human management role.
Is used in biological pest control?
Biological control involves the mass-production and release of natural enemies such as parasitoids and predators to control pest insects in an environmentally sound manner. Radiation is used to increase the applicability, cost-effectiveness and safety of rearing, shipping and deploying such natural enemies.
When to use inundative and inoculative biological strategies?
These strategies are used to control pests when natural enemies are absent, when the control due to natural enemies would naturally occur too late to prevent damage, or when natural enemies occur naturally in numbers too low to provide effective control.
When do inundative releases have to be repeated?
Because control is only due to the released individuals, inundative releases would have to be repeated if pest populations increase again after natural enemies are released.
What is the purpose of augmentative biological control?
Augmentative biological control (or “augmentation”) is simply the release of large numbers of insectary reared natural enemies with the goal of “augmenting” natural enemy populations or “inundating” pest populations with natural enemies.
Which is an example of a biological control program?
There are many examples of successful classical biological control programs. One of the earliest successes was with the cottony cushion scale, a pest that was devastating the California citrus industry in the late 1800s. A predatory insect, the vedalia beetle, and a parasitoid fly were introduced from Australia.
