How can beneficial microorganisms control insect pests?
Microbial control of insects is achieved through the inundative application of allowable formulations of insect-pathogenic bacteria (e.g., Bacillus thuringiensis), insect-pathogenic fungi (e.g., Beauveria bassiana), or insect viruses.
What is the biological method of controlling pest?
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.
What is microbial pest control?
Microbial pest control agents or MPCAs are the active ingredients that drive the efficacy of biologically derived pesticides. A specific microorganism can have multiple strains, so understanding and identifying it correctly helps to determine the organism’s effect on both humans and the environment.
What’s an example of biological control?
Examples of biological control include the destruction of the citrophilus mealybug in California by two parasitic species of chalcid wasps imported from Australia, Coccophagus gurneyi and Tetracnemus pretiosus; the effective predation of an Australian ladybird beetle, or vedalia beetle (Rodolia cardinalis), on the …
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.
What are the advantages of biological control?
Advantages of biological control An effective agent will search out all suitable plants of the weed. Biological control has no adverse effect on human health or the environment. Biological control is self-sustaining.

Why is exerting a biological control of insects harmful?
Biological toxin material is derived from microorganism, for example, fungus or bacterium, this is called microbial toxin. These types of microorganism may cause death or rupture the gut of the pest because these entomopathogens are highly toxic.
What is meant by the biological control of insects?
Biological control is a component of an integrated pest management strategy. It is defined as the reduction of pest populations by natural enemies and typically involves an active human role. Natural enemies of insect pests, also known as biological control agents, include predators, parasitoids, and pathogens.
How does the natural control of insect occur?
Natural control refers to the maintenance of insect populations within certain bounds by environmental conditions, or factors. Both non-biological and biological factors contribute to the natural control of insects. These include: Physical factors such as weather (e.g. cold winters can reduce some insect populations).

How does a systemic insecticide work?
Systemic insecticides kill insects when they ingest a lethal concentration during feeding. Systemic fungicides form a barrier on and within the plant, killing fungal spores and fungal roots, called hyphae, as they germinate and begin to grow.
