Biopesticides are classified into three main types: microbial, biochemical, and plant-incorporated protectants. Each type targets specific pests using natural mechanisms.
Biopesticides offer an eco-friendly alternative to chemical pesticides. Derived from natural materials, they ensure minimal impact on the environment and non-target species. Microbial biopesticides include bacteria, fungi, and viruses that attack specific pests. Biochemical biopesticides use naturally occurring substances like pheromones or plant extracts to disrupt pest behaviors.

Categories Of Biopesticides
Biopesticides are natural substances used to control pests. They are safer for the environment. They come from animals, plants, bacteria, and certain minerals. Biopesticides have several categories. Each type works differently to protect crops. This blog will explore three main types of biopesticides.
Microbial Biopesticides
Microbial biopesticides use microorganisms to fight pests. These microorganisms can be bacteria, fungi, or viruses. They target specific pests without harming other organisms. This makes them safe for the environment.
Bacillus thuringiensis (Bt) is a common microbial biopesticide. Bt produces toxins that kill insect larvae. It is used widely in agriculture. Farmers spray Bt on crops to control pests.
Another example is Trichoderma fungi. These fungi protect plants from harmful fungi. They grow on plant roots and act as a shield.
- Bacteria: Bacillus thuringiensis (Bt)
- Fungi: Trichoderma
- Viruses: Baculoviruses
Microbial biopesticides offer a sustainable way to control pests. They reduce the need for chemical pesticides. This helps to protect the environment and human health.
Biochemical Biopesticides
Biochemical biopesticides are natural substances. They control pests by non-toxic mechanisms. These substances include pheromones, plant extracts, and essential oils.
Pheromones are chemicals that insects use to communicate. Farmers use pheromones to disrupt insect mating. This reduces pest populations without killing them.
Neem oil is a popular plant extract. It comes from the neem tree. Neem oil repels and kills a variety of pests. It is safe for beneficial insects and humans.
Essential oils like peppermint oil also act as biopesticides. They repel insects with their strong smell.
| Type | Example | Use |
|---|---|---|
| Pheromones | Mating disruption | Reduce insect populations |
| Plant Extracts | Neem oil | Repel and kill pests |
| Essential Oils | Peppermint oil | Repel insects |
Biochemical biopesticides offer a natural way to manage pests. They are safe and eco-friendly. This makes them an excellent choice for sustainable farming.
Plant-incorporated Protectants (pips)
Plant-Incorporated Protectants (PIPs) are plants that produce their own pesticides. Scientists use genetic engineering to create these plants. PIPs protect crops from pests without the need for external sprays.
Bt cotton is a well-known example of a PIP. This cotton plant produces Bt toxin. The toxin kills specific insect pests that feed on the plant.
Another example is Bt corn. This corn plant also produces Bt toxin. It protects the corn from pests like the European corn borer.
- Bt cotton: Produces Bt toxin to kill pests
- Bt corn: Produces Bt toxin to protect against European corn borer
PIPs reduce the need for chemical pesticides. This helps to protect the environment. Farmers can grow healthier crops with fewer inputs. This makes farming more sustainable and cost-effective.

Mode Of Action
Biopesticides are natural pesticides derived from animals, plants, bacteria, and certain minerals. They are used in controlling pests by non-toxic means. Understanding the mode of action of biopesticides helps in selecting the right type for specific pests. This ensures effective pest management and promotes sustainable agriculture.
Microbial Biopesticides
Microbial biopesticides contain living organisms or their byproducts. These can be bacteria, fungi, viruses, or protozoans. They work by infecting and killing pests. Bacillus thuringiensis (Bt) is a common example. Bt produces toxins that target specific insects. When pests ingest these toxins, their guts are destroyed, leading to death.
Below are some types of microbial biopesticides:
- Bacteria: Effective against caterpillars and beetles.
- Fungi: Targets aphids, whiteflies, and other soft-bodied insects.
- Viruses: Mainly used against moths and butterflies.
- Protozoans: Effective in controlling mosquito larvae.
Microbial biopesticides are specific to their target pests. They do not harm beneficial insects, animals, or humans. This makes them a safe choice for integrated pest management programs.
Biochemical Biopesticides
Biochemical biopesticides are natural substances that control pests. These include plant extracts, pheromones, and natural repellents. They interfere with the mating, feeding, or growth processes of pests. Pheromones are chemicals that attract pests into traps. This disrupts their mating cycle and reduces pest populations.
Some common biochemical biopesticides are:
- Neem oil: Extracted from neem trees, it repels insects and disrupts their growth.
- Insect growth regulators (IGRs): These prevent pests from maturing and reproducing.
- Plant oils: Oils like eucalyptus and clove have insecticidal properties.
- Repellents: Substances that deter pests from plants.
Biochemical biopesticides are safe for humans and the environment. They offer a natural way to control pests without harmful chemicals.
Pips
PIPs, or Plant-Incorporated Protectants, are pesticidal substances produced by plants. These plants are genetically modified to produce specific proteins. These proteins protect them from pests. For example, Bt corn is engineered to produce Bt toxin. This makes it resistant to certain insects.
PIPs offer several benefits:
- Targeted action: Only affects specific pests.
- Reduced pesticide use: Farmers use fewer chemical pesticides.
- Environmental safety: Lower risk to non-target organisms.
PIPs are developed through genetic engineering. This ensures that the pesticidal proteins are safe for human consumption and the environment. Regulatory agencies rigorously test these plants before they are approved for use.
